In this blog, we’re going to know about the useful techniques you can use to improve your website performance, be it front-end or back-end.

Introduction

Before we start to optimize your website’s performance, it’s essential to set a goal for where you want it to be. That can be difficult for you if you’re not aware of what acceptable page speed is.

As per the Google’s latest guidelines, the faster your website loads, the higher the chances are to achieve favourble results, and improve your conversion rate.

That’s the main reason why website optimization is the most crucial aspect for any website owner. Here we’re going to measure your website performance and the tips that help increase website loading speed by optimizing your website’s back-end and front-end because front-end issues are equally important as back-end.

So, let’s get started!

Facing Website Performance Issues?

A website with good performance represents a brand and its image. It is essential to keep an eye on your website performance as it doesn’t take much time to have a better UI/UX. Every user expects their website to be best and fast.

Sometimes, the website does not work correctly, and you face issues that may impact your business and your activities. Out of 20, 17 digital product owners believe that there might be back-end issues that cause trouble to the website performance. Well, they are undoubtedly right. Almost 60% to 70% is the possibility that there could be Back-end issues. However, when it comes to improve your website performance, do you know it could be slow down because of a front-end issue as well? Some of you will agree, whereas some of you won’t.

According to Steve Souders, 80% of the average page load times occur after the markup is completely downloaded. For your users, a 50% speedup in your front-end code is going to mean a lot more to them than a 50% speedup in your back-end code.

Common website performance issues (Back-end only)

  1. The N+! Query Problem

  2. Database optimization

  3. Server and Browser Caching

  4. Web Hosting Solutions

  5. Content Delivery Network (CDN)

**Only Back-end Issues? What if There are Front-end Issues Which are Affecting your Website Performance.

The back-end issues, as mentioned above, are not the ones that can hamper. There could be front-end issues as well. Because of these common front-end issues, people won’t even give your application a second thought if it is not visually appealing. Nobody will care if your back-end is fast if your front-end is not convincing. Moreover, solving front-end issues won’t be that much more critical than it is in the back-end. So, let’s have a look at common front-end issues.

  1. Lazy loading

  2. Large images

  3. Unused CSS

  4. Brotli and Gzip Compression

These are the common front-end issues people come across, and that hampers the website performance for sure.
Now, you might be wondering. We already know these common issues, and some of you might know how to solve them as well. But let me tell you that there is always a learning curve. Let’s educate each other about the issues and how to get rid of them with better solutions.

You must be wondering if there is any one-stop solution that can solve back end and front-end problems both. And guess what? A full-stack web developer is a one-stop solution and knows how to get rid of them with better solutions.

A full-stack web developer can be a one-stop solution to solve the front-end as well as back-end issues and guide you properly on “how to speed up website performance?

What is a Full Stack Developer?

To put it in a nutshell, a full stack developer meaning a well-versed programmer who has the expertise of both ends to offer a smooth user experience: front-end and back-end development. A full-stack developer can jump from one part of the application to another without significant overload. This is a huge advantage when planning forward or when designing new features. That’s why more and more developer wants to become a full-stack developer in 2020.

A full-stack developer can efficiently work on both front-end and back-end technologies like;

Front-end: Angular, Vue, and React

Back-end: ROR, Laravel, .NET, PHP, Python, Golang, and many more.

A full-stack developer is the one who is well-versed with more than one technology in a project and have in-depth knowledge of various tech stacks. So, let’s get some details on “How to improve website performance tips.

How a Full-stack Developer Can Help You Solve Back-end Issues

  1. The N+1 Query Problem

The N+1 query intricacy frequently happens when any queries are assigned to associated fields in your database instead of printing one compound SQL query, including all the reports which are to be regained. Using eager loading, all associated questions are requested with a single entity instead of multiple queries that may slow down your application’s performance.

  1. Database Optimization

Database optimization plays a significantly vital role in improving website performance. Sometimes unoptimized databases may slow down your performance and denormalize your database.

Normalizing a Database
Normalizing your database is a logical outcome when designing a relational database, but some developers still decline this process at times. Optimizing databases reduces the amount of space that a database requires and organizes your data to improve website performance.

Database Indexes
A common issue that slows down your website’s performance is database indexes. If database indexes aren’t used properly or are not used properly, then the website performance may slow down. Database indexes serve the same purpose as indexes in a book; every index element has the required object’s name and an identifier showing its location. The primary purpose of creating database indexes is to search for matching data instead of going through all the searches in the database.

Database Denormalization
It is a speculative correction of any normalized database, so it doesn’t give up standard forms. Denormalization reduces the time required to select queries and adds redundant data into existing tables to make it more accessible.

  1. Server and browser caching

In computing, caching is the process of storing data and reloading it so that future requests for that data can be served faster, and the web page isn’t rendered repeatedly for each user.

Caching allows users to work with the bulk of data quickly while using minimal server resources to be implemented on the client and server-side.

Fragment Caching
Fragment caching typically refers to boundless caching. Your website’s web pages are cached using fragment caching for dynamic web applications that may quickly become irrelevant. Complex web apps contain many blocks and components, so it needs to be re-rendered when any modifications are done to the web pages.

Page Caching and Action Caching
Page caching is the most effective and widely used caching for performance optimization, which is wholly implemented on the webserver. After executing on the web server, it returns cached static content to your application. But in some cases, page caching is not suitable for applications having frequent results that would produce content a user has seen before.

Caching enhances your website performance by diminishing the load time and server load time because every cached web page can be conveyed to users’ multiple times.

  1. Web hosting service

Web hosting services are for backups and server management. It helps to improve your website performance depending on the web hosting service and web hosts with various capabilities and scalability options. Compared to all web hosting, shared web hosting is the most popular, widely used, and popular web hosting.

Here we’re going to cover VPS, cloud hosting, and dedicated hosting that plays a significant role in performance optimization, and it has enough capabilities like how to improve your website performance.

Virtual Private Servers
A low-cost shared web hosting package and costly dedicated hosting connect the VPS that extends a personal virtual server for a specific client and configures shared hosting considering your configurations don’t affect other clients.

The prices of VPS are affordable, but it may go up if your website requires some additional services. It is an optimal solution for your website, having average traffic that expects traffic spikes during specific periods.

Cloud Hosting
Cloud hosting is suitable for small and medium businesses implementing applications with uncertain traffic for eCommerce websites. Computing resources becomes easy if you’re using cloud services and pay only for what you use. Therefore, with cloud hosting, you’re not required to pay for resources that your website doesn’t use.

Dedicated Hosting
Dedicated hosting offers you a dedicated server that pertains only to you, which is an unreasonable solution. First, you’re obligated to pay the server rent, which is 0 per month. Secondly, you should have a system administrator that can manage your server. This way, with dedicated hosting, you get all the power and resources that you need from the operating system to the type of memory where security and speed are critical.

  1. Content Delivery Network (CDN)

Content delivery network, commonly referred to as CDN, is a distributed proxy server called “edge servers.” its functionality helps you cache static content such as CSS files, JavaScript files, and images files, which is also dynamic cache content.

It helps to improve website performance, enhancing page load speed and performance on its server’s location to decrease your performance.

Reduced Costs
CDN allows users to retrieve requested content faster. Imagine that any user from the USA is trying to retrieve content from a server-based India. If your website is working great and gaining popularity, it is proof that more people will access it. Do you think these issues might have caused your website performance in the past? If yes, then not to worry, you will get solutions for these back-end issues once you complete this blog.

What are the solutions for front-end issues?

  1. Lazy Loading

When you request to load a web page, the browser requests for its images, overlooking other things like whether they’re in the viewport or out of sight. With lazy loading, all the visible images and asynchronous load the rest on-demand when the user scrolls. It helps you to improve website performance, reducing the loading request.

Lazy Loading medium

Lazy loading was implemented with the Intersection Observer API in 2019. The exceptionally well-written tutorial was implemented by Google showing the importance of lazy loading, which you should check out if it’s something you’re looking for.

  1. Responsive Images

Responsive Images

It is another significant way to reduce your website’s page size for the better use of viewport space. To show the appropriate image size depending on the viewport size, implement the srcset and sizes attributes like:

< picture > < source media=“(max-width: 799px)” srcset=“dog-480w.jpg” > < source media=“(min-width: 800px)” srcset=“dog-800w.jpg” > < img src=“dog-800w.jpg” alt=“A picture of a dog” > < /picture >

  1. Remove Unused CSS

In modern front-end development, Bootstrap is a suite of highly reusable classes for creating quicker and more responsive UI creation.

  1. Brotli and gzip Compression

With the help of compression devices like gzip and Google’s Brotli, it is so convenient to decrease the file sizes requests:

Brotli and gzip Compression

When you compare the CSS and JS files, you’ll notice that the PNG’s compression ratio is pretty dull. Gzip and Brotli are perfectly suited for text-based files where the repetition rate is pretty higher for the compression to be more successful.

Top Front-end web development and Back-end Web Development Tools 2020

Best front end optimization tools in web development are:

React, Vue, or Angular (UI frameworks)
Gatsby, Ruby on Rails, or NodeJS (Web framework)
Babel or TypeScript (Compiler)
Webpack, Rollup, or Parcel (Bundlers)
Sass, Bourbon, or PostCSS (CSS tools)

Best back end optimization tools in web development are:

AWS EC2 (Cloud Servers)
AWS Lambda or AWS S3 (Serverless Services)
MongoDB or PostgreSQL (NoSQL Databases)
Languages like Python or Javascript via NodeJS
Serverless Framework (web application framework)
Not only this, but a full stack web developer can also help you with other tools and technologies to improve your website performance and scale up your business.

If you have cross-platform applications built-in Flutter, React Native, Ios, Android, Ionic, they are well-versed enough to help you with 360-degree solutions.

Conclusion:
Currently, a typical user expects web pages to load less than after 3 seconds. If you don’t meet this expectation barrier, you lose a lot of website traffic and, as a result, your revenue.

So, website performance is the most important concern for any digital product owner who has to look into it frequently, regardless of its size. Nobody likes a slow website. So, I hope your purpose of landing on this blogpost is served, and you got a better understanding of why you should hire full stack developer or a team to improve your website performance. Full-stack developers are the ones who are well-versed and skilled enough in offering top-class solutions for both front-end as well as back-end issues.

A Simple Wrapper Around Amplify AppSync Simulator

This serverless plugin is a wrapper for amplify-appsync-simulator made for testing AppSync APIs built with serverless-appsync-plugin.

Install

npm install serverless-appsync-simulator
# or
yarn add serverless-appsync-simulator

Usage

This plugin relies on your serverless yml file and on the serverless-offline plugin.

plugins:
  - serverless-dynamodb-local # only if you need dynamodb resolvers and you don't have an external dynamodb
  - serverless-appsync-simulator
  - serverless-offline

Note: Order is important serverless-appsync-simulator must go before serverless-offline

To start the simulator, run the following command:

sls offline start

You should see in the logs something like:

...
Serverless: AppSync endpoint: http://localhost:20002/graphql
Serverless: GraphiQl: http://localhost:20002
...

Configuration

Put options under custom.appsync-simulator in your serverless.yml file

| option | default | description | | ------------------------ | -------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------- | | apiKey | 0123456789 | When using API_KEY as authentication type, the key to authenticate to the endpoint. | | port | 20002 | AppSync operations port; if using multiple APIs, the value of this option will be used as a starting point, and each other API will have a port of lastPort + 10 (e.g. 20002, 20012, 20022, etc.) | | wsPort | 20003 | AppSync subscriptions port; if using multiple APIs, the value of this option will be used as a starting point, and each other API will have a port of lastPort + 10 (e.g. 20003, 20013, 20023, etc.) | | location | . (base directory) | Location of the lambda functions handlers. | | refMap | {} | A mapping of resource resolutions for the Ref function | | getAttMap | {} | A mapping of resource resolutions for the GetAtt function | | importValueMap | {} | A mapping of resource resolutions for the ImportValue function | | functions | {} | A mapping of external functions for providing invoke url for external fucntions | | dynamoDb.endpoint | http://localhost:8000 | Dynamodb endpoint. Specify it if you're not using serverless-dynamodb-local. Otherwise, port is taken from dynamodb-local conf | | dynamoDb.region | localhost | Dynamodb region. Specify it if you're connecting to a remote Dynamodb intance. | | dynamoDb.accessKeyId | DEFAULT_ACCESS_KEY | AWS Access Key ID to access DynamoDB | | dynamoDb.secretAccessKey | DEFAULT_SECRET | AWS Secret Key to access DynamoDB | | dynamoDb.sessionToken | DEFAULT_ACCESS_TOKEEN | AWS Session Token to access DynamoDB, only if you have temporary security credentials configured on AWS | | dynamoDb.* | | You can add every configuration accepted by DynamoDB SDK | | rds.dbName | | Name of the database | | rds.dbHost | | Database host | | rds.dbDialect | | Database dialect. Possible values (mysql | postgres) | | rds.dbUsername | | Database username | | rds.dbPassword | | Database password | | rds.dbPort | | Database port | | watch | - *.graphql
- *.vtl | Array of glob patterns to watch for hot-reloading. |

Example:

custom:
  appsync-simulator:
    location: '.webpack/service' # use webpack build directory
    dynamoDb:
      endpoint: 'http://my-custom-dynamo:8000'

Hot-reloading

By default, the simulator will hot-relad when changes to *.graphql or *.vtl files are detected. Changes to *.yml files are not supported (yet? - this is a Serverless Framework limitation). You will need to restart the simulator each time you change yml files.

Hot-reloading relies on watchman. Make sure it is installed on your system.

You can change the files being watched with the watch option, which is then passed to watchman as the match expression.

e.g.

custom:
  appsync-simulator:
    watch:
      - ["match", "handlers/**/*.vtl", "wholename"] # => array is interpreted as the literal match expression
      - "*.graphql"                                 # => string like this is equivalent to `["match", "*.graphql"]`

Or you can opt-out by leaving an empty array or set the option to false

Note: Functions should not require hot-reloading, unless you are using a transpiler or a bundler (such as webpack, babel or typescript), un which case you should delegate hot-reloading to that instead.

Resource CloudFormation functions resolution

This plugin supports some resources resolution from the Ref, Fn::GetAtt and Fn::ImportValue functions in your yaml file. It also supports some other Cfn functions such as Fn::Join, Fb::Sub, etc.

Note: Under the hood, this features relies on the cfn-resolver-lib package. For more info on supported cfn functions, refer to the documentation

Basic usage

You can reference resources in your functions' environment variables (that will be accessible from your lambda functions) or datasource definitions. The plugin will automatically resolve them for you.

provider:
  environment:
    BUCKET_NAME:
      Ref: MyBucket # resolves to `my-bucket-name`

resources:
  Resources:
    MyDbTable:
      Type: AWS::DynamoDB::Table
      Properties:
        TableName: myTable
      ...
    MyBucket:
      Type: AWS::S3::Bucket
      Properties:
        BucketName: my-bucket-name
    ...

# in your appsync config
dataSources:
  - type: AMAZON_DYNAMODB
    name: dynamosource
    config:
      tableName:
        Ref: MyDbTable # resolves to `myTable`

Override (or mock) values

Sometimes, some references cannot be resolved, as they come from an Output from Cloudformation; or you might want to use mocked values in your local environment.

In those cases, you can define (or override) those values using the refMap, getAttMap and importValueMap options.

  • refMap takes a mapping of resource name to value pairs
  • getAttMap takes a mapping of resource name to attribute/values pairs
  • importValueMap takes a mapping of import name to values pairs

Example:

custom:
  appsync-simulator:
    refMap:
      # Override `MyDbTable` resolution from the previous example.
      MyDbTable: 'mock-myTable'
    getAttMap:
      # define ElasticSearchInstance DomainName
      ElasticSearchInstance:
        DomainEndpoint: 'localhost:9200'
    importValueMap:
      other-service-api-url: 'https://other.api.url.com/graphql'

# in your appsync config
dataSources:
  - type: AMAZON_ELASTICSEARCH
    name: elasticsource
    config:
      # endpoint resolves as 'http://localhost:9200'
      endpoint:
        Fn::Join:
          - ''
          - - https://
            - Fn::GetAtt:
                - ElasticSearchInstance
                - DomainEndpoint

Key-value mock notation

In some special cases you will need to use key-value mock nottation. Good example can be case when you need to include serverless stage value (${self:provider.stage}) in the import name.

This notation can be used with all mocks - refMap, getAttMap and importValueMap

provider:
  environment:
    FINISH_ACTIVITY_FUNCTION_ARN:
      Fn::ImportValue: other-service-api-${self:provider.stage}-url

custom:
  serverless-appsync-simulator:
    importValueMap:
      - key: other-service-api-${self:provider.stage}-url
        value: 'https://other.api.url.com/graphql'

Limitations

This plugin only tries to resolve the following parts of the yml tree:

  • provider.environment
  • functions[*].environment
  • custom.appSync

If you have the need of resolving others, feel free to open an issue and explain your use case.

For now, the supported resources to be automatically resovled by Ref: are:

  • DynamoDb tables
  • S3 Buckets

Feel free to open a PR or an issue to extend them as well.

External functions

When a function is not defined withing the current serverless file you can still call it by providing an invoke url which should point to a REST method. Make sure you specify "get" or "post" for the method. Default is "get", but you probably want "post".

custom:
  appsync-simulator:
    functions:
      addUser:
        url: http://localhost:3016/2015-03-31/functions/addUser/invocations
        method: post
      addPost:
        url: https://jsonplaceholder.typicode.com/posts
        method: post

Supported Resolver types

This plugin supports resolvers implemented by amplify-appsync-simulator, as well as custom resolvers.

From Aws Amplify:

  • NONE
  • AWS_LAMBDA
  • AMAZON_DYNAMODB
  • PIPELINE

Implemented by this plugin

  • AMAZON_ELASTIC_SEARCH
  • HTTP

However, when it comes to improve your website performance, do you know it could be slow down because of a front-end issue as well? Some of you will agree, whereas some of you won’t.

According to Steve Souders, 80% of the average page load times occur after the markup is completely downloaded. For your users, a 50% speedup in your front-end code is going to mean a lot more to them than a 50% speedup in your back-end code.

Only Back-end Issues? What if There are Front-end Issues Which are Affecting your Website Performance.

The back-end issues, as mentioned above, are not the ones that can hamper. There could be front-end issues as well. Because of these common front-end issues, people won’t even give your application a second thought if it is not visually appealing. Nobody will care if your back-end is fast if your front-end is not convincing. Moreover, solving front-end issues won’t be that much more critical than it is in the back-end. So, let’s have a look at common front-end issues.

  1. Lazy loading
  2. Large size images
  3. Unused CSS
  4. Brotli and Gzip Compression

These are the common front-end issues people come across, and that hampers the website performance for sure.
Now, you might be wondering. We already know these common issues, and some of you might know how to solve them as well. But let me tell you that there is always a learning curve. Let’s educate each other about the issues and how to get rid of them with better solutions.

You must be wondering if there is any one-stop solution that can solve back end and front-end problems both. And guess what? A full-stack web developer is a one-stop solution and knows how to get rid of them with better solutions.

A full-stack web developer can be a one-stop solution to solve the front-end as well as back-end issues.

What is a Full Stack Developer?

To put it in a nutshell, a full stack developer meaning a well-versed programmer who has the expertise of both ends to offer a smooth user experience: front-end and back-end development.A full-stack developer can jump from one part of the application to another without significant overload. This is a huge advantage when planning forward or when designing new features. That’s why more and more developer wants to become a full-stack developer in 2020.

A full-stack developer can efficiently work on both front-end and back-end technologies like;

**Front-end: Angular, Vue, and React **

**Back-end: ROR, Laravel, .NET, PHP, Python, Golang, and many more. **

A full-stack developer is the one who is well-versed with more than one technology in a project and came up with great solutions no matter what scale of application it is.

How a Full-stack Developer Can Help You Solve Back-end Issues

1. The N+1 Query Problem

The N+1 query intricacy frequently happens when any queries are assigned to associated fields in your database instead of printing one compound SQL query, including all the reports which are to be regained. Using eager loading, all associated questions are requested with a single entity instead of multiple queries that may slow down your application’s performance.

2.Database Optimization

Database optimization plays a significantly vital role in improving your website performance. Sometimes unoptimized databases may slow down your performance and denormalize your database.

*** Normalizing a Database**

Normalizing your database is a logical outcome when designing a relational database, but some developers still decline this process at times. Optimizing databases reduces the amount of space that a database requires and organizes your data to improve website performance.

*** Database Indexes**

A common issue that slows down your website’s performance is database indexes. If database indexes aren’t used properly or are not used properly, then the website performance may slow down. Database indexes serve the same purpose as indexes in a book; every index element has the required object’s name and an identifier showing its location. The primary purpose of creating database indexes is to search for matching data instead of going through all the searches in the database.

*** Database Denormalization**

It is a speculative correction of any normalized database, so it doesn’t give up standard forms. Denormalization reduces the time required to select queries and adds redundant data into existing tables to make it more accessible.

3.Server and browser caching

In computing, caching is the process of storing data and reloading it so that future requests for that data can be served faster, and the web page isn’t rendered repeatedly for each user. Caching allows users to work with the bulk of data quickly while using minimal server resources to be implemented on the client and server-side.

*** Fragment Caching**

Fragment caching typically refers to boundless caching. Your website’s web pages are cached using fragment caching for dynamic web applications that may quickly become irrelevant. Complex web apps contain many blocks and components, so it needs to be re-rendered when any modifications are done to the web pages.

*** Page Caching and Action Caching**

Page caching is the most effective and widely used caching for performance optimization, which is wholly implemented on the webserver. After executing on the web server, it returns cached static content to your application. But in some cases, page caching is not suitable for applications having frequent results that would produce content a user has seen before.

Caching enhances your website performance by diminishing the load time and server load time because every cached web page can be conveyed to users’ multiple times.

4.Web hosting service

Web hosting services are for backups and server management. It helps to improve your website performance depending on the web hosting service and web hosts with various capabilities and scalability options. Compared to all web hosting, shared web hosting is the most popular, widely used, and popular web hosting.

Here we’re going to cover VPS, cloud hosting, and dedicated hosting that plays a significant role in performance optimization, and it has enough capabilities to improve your website performance.

*** Virtual Private Servers**

A low-cost shared web hosting package and costly dedicated hosting connect the VPS that extends a personal virtual server for a specific client and configures shared hosting considering your configurations don’t affect other clients.

The prices of VPS are affordable, but it may go up if your website requires some additional services. It is an optimal solution for your website, having average traffic that expects traffic spikes during specific periods.

*** Cloud Hosting**

Cloud hosting is suitable for small and medium businesses implementing applications with uncertain traffic for eCommerce websites. Computing resources becomes easy if you’re using cloud services and pay only for what you use. Therefore, with cloud hosting, you’re not required to pay for resources that your website doesn’t use.

*** Dedicated Hosting**

Dedicated hosting offers you a dedicated server that pertains only to you, which is an unreasonable solution. First, you’re obligated to pay the server rent, which is $150 per month. Secondly, you should have a system administrator that can manage your server. This way, with dedicated hosting, you get all the power and resources that you need from the operating system to the type of memory where security and speed are critical.

5. Content Delivery Network (CDN)

Content delivery network, commonly referred to as CDN, is a distributed proxy server called “edge servers.” its functionality helps you cache static content such as CSS files, JavaScript, and images, which is also dynamic cache content.

It helps to improve your website performance, enhancing page load speed and performance on its server’s location to decrease your performance.

Reduced Costs

CDN allows users to retrieve requested content faster. Imagine that any user from the USA is trying to retrieve content from a server-based India. If your website is working great and gaining popularity, it is proof that more people will access it. Do you think these issues might have caused your website performance in the past? If yes, then not to worry, you will get solutions for these back-end issues once you complete this blog.

What are the solutions for front-end issues?

1. Lazy Loading

When you request to load a web page, the browser requests for its images, overlooking other things like whether they’re in the viewport or out of sight. With lazy loading, all the visible images and asynchronous load the rest on-demand when the user scrolls. It helps you to improve your website performance, reducing the loading request.

This is image title

Lazy Loading medium Lazy loading was implemented with the Intersection Observer API in 2019. The exceptionally well-written tutorial was implemented by Google showing the importance of lazy loading, which you should check out if it’s something you’re looking for.

2. Responsive Images

It is another significant way to reduce your website’s page size for the better use of viewport space. To show the appropriate image size depending on the viewport size, implement the srcset and sizes attributes like:

< picture >
< source media=“(max-width: 799px)” srcset=“dog-480w.jpg” > < source media=“(min-width: 800px)” srcset=“dog-800w.jpg” >
< img src=“dog-800w.jpg” alt=“A picture of a dog” > < /picture >

3. Remove Unused CSS

In modern front-end development, Bootstrap is a suite of highly reusable classes for creating quicker and more responsive UI creation.

Here is the example showing a typical grid system implemented using Bootstrap:

This is image title

All the classes shown in the following example create columns with full-width and generate a classic 3-column layout. It is generated in SASS file-based on the breakpoint variables provided to Bootstrap.

4. Brotli and gzip Compression

With the help of compression devices like gzip and Google’s Brotli, it is so convenient to decrease the file sizes requests:

This is image title

When you compare the CSS and JS files, you’ll notice that the PNG’s compression ratio is pretty dull. Gzip and Brotli are perfectly suited for text-based files where the repetition rate is pretty higher for the compression to be more successful.

Top Front-end web development and Back-end Web Development Tools 2020

Best front end tools in web development are:

  • React, Vue, or Angular (UI frameworks)
  • Gatsby, Ruby on Rails, or NodeJS (Web framework)
  • Babel or TypeScript (Compiler)
  • Webpack, Rollup, or Parcel (Bundlers)
  • Sass, Bourbon, or PostCSS (CSS tools)

Best back end tools in web development are:

  • AWS EC2 (Cloud Servers)
  • AWS Lambda or AWS S3 (Serverless Services)
  • MongoDB or PostgreSQL (NoSQL Databases)
  • Languages like Python or Javascript via NodeJS
  • Serverless Framework (web application framework)

Not only this, but a full stack web developer can also help you with other tools and technologies to improve your website performance and scale up your business.

If you have cross-platform applications built-in Flutter, React Native, Ios, Android, Ionic, they are well-versed enough to help you with 360-degree solutions.

Conclusion:

Currently, a typical user expects web pages to load less than after 3 seconds. If you don’t meet this expectation barrier, you lose a lot of website traffic and, as a result, your revenue.

So, website performance is the most important concern for any digital product owner who has to look into it frequently, regardless of its size. Nobody likes a slow website. So, I hope your purpose of landing on this blogpost is served, and you got a better understanding of why you should hire full stack developer or a team to improve your website performance. Full-stack developers are the ones who are well-versed and skilled enough in offering top-class solutions for both front-end as well as back-end issues.

Unfortunately, sometimes you may face challenges on the website that are clunky and bothersome to use. The poorly optimized websites may contain multiple issues and errors, including browser incompatibilities, slow loading time, etc. But we think that there may be some back-end issues that affect the website performance, but have Quick Summary: In today’s tech world, numerous websites are accessed every day for various reasons. Unfortunately, sometimes you may face challenges on the website that are clunky and bothersome to use. The poorly optimized websites may contain multiple issues and errors, including browser incompatibilities, slow loading time, etc. But we think that there may be some back-end issues that affect the website performance, but have you ever wondered if front-end issues may also slow down your performance. In this blog, we’re going to know about the useful techniques you can use to improve your website performance, be it front-end or back-end.

Introduction

Before we start to optimize your website’s performance, it’s essential to set a goal for where you want it to be. That can be difficult for you if you’re not aware of what acceptable page speed is.

As per the Google’s latest guidelines, the faster your website loads, the higher the chances are to achieve favourble results, and improve your conversion rate.

That’s the main reason why website optimization is the most crucial aspect for any website owner. Here we’re going to measure your website performance and the tips that help increase website loading speed by optimizing your website’s back-end and front-end because front-end issues are equally important as back-end.

So, let’s get started!

Facing Website Performance Issues?

A website with good performance represents a brand and its image. It is essential to keep an eye on your website performance as it doesn’t take much time to have a better UI/UX. Every user expects their website to be best and fast.

Sometimes, the website does not work correctly, and you face issues that may impact your business and your activities. Out of 20, 17 digital product owners believe that there might be back-end issues that cause trouble to the website performance. Well, they are undoubtedly right.

Content delivery network, commonly referred to as CDN, is a distributed proxy server called “edge servers.” its functionality helps you cache static content such as CSS files, JavaScript files, and images files, which is also dynamic cache content.

It helps to improve website performance, enhancing page load speed and performance on its server’s location to decrease your performance.

Reduced Costs
CDN allows users to retrieve requested content faster. Imagine that any user from the USA is trying to retrieve content from a server-based India. If your website is working great and gaining popularity, it is proof that more people will access it. Do you think these issues might have caused your website performance in the past? If yes, then not to worry, you will get solutions for these back-end issues once you complete this blog.

What are the solutions for front-end issues?

  1. Lazy Loading

When you request to load a web page, the browser requests for its images, overlooking other things like whether they’re in the viewport or out of sight. With lazy loading, all the visible images and asynchronous load the rest on-demand when the user scrolls. It helps you to improve website performance, reducing the loading request.

Lazy Loading medium

Lazy loading was implemented with the Intersection Observer API in 2019. The exceptionally well-written tutorial was implemented by Google showing the importance of lazy loading, which you should check out if it’s something you’re looking for.

  1. Responsive Images

Responsive Images

It is another significant way to reduce your website’s page size for the better use of viewport space. To show the appropriate image size depending on the viewport size, implement the srcset and sizes attributes like:

< picture > < source media=“(max-width: 799px)” srcset=“dog-480w.jpg” > < source media=“(min-width: 800px)” srcset=“dog-800w.jpg” > < img src=“dog-800w.jpg” alt=“A picture of a dog” > < /picture >

  1. Remove Unused CSS

In modern front-end development, Bootstrap is a suite of highly reusable classes for creating quicker and more responsive UI creation.

  1. Brotli and gzip Compression

With the help of compression devices like gzip and Google’s Brotli, it is so convenient to decrease the file sizes requests:

Brotli and gzip Compression

When you compare the CSS and JS files, you’ll notice that the PNG’s compression ratio is pretty dull. Gzip and Brotli are perfectly suited for text-based files where the repetition rate is pretty higher for the compression to be more successful.
