Real-time Salad order tracker application using Full Stack

SALAD ORDER TRACKER APPLICATION

  • A real time application to track orders online. Users can order Salads, view cart, and check the delivery status.
  • Part of 100 days of code challenge.

Technology Stack

  1. JavaScript - NodeJS Framework
  2. ExpressJS
  3. EJS Template
  4. YARN (package manager)
  5. MongoDB
  6. Laravel Mix
  7. Tailwind CSS
  8. Socket.io
  9. ES6
  10. SCSS

Project Structure - MVC pattern

  1. Model is the Database part of the application. It represents the structure of data, the format and the constraints with which it is stored.
  2. View is the User Interface part. It utilizes the Model(using controllers) and presents data as static/dynamic pages to the user for further tasks.
  3. Controller is the request-response handler. The user interacts with the View, which in turn generates a request, that will be handled by a controller. The controller renders the appropriate view with the model data as a response.

Installations

  1. Download & Install NodeJS
  2. Download & Install YARN
  3. Download & Install GIT
  4. Steps for Installing Laravel
  5. Using Tailwind CSS via CDN (No need to install complete framework)
  6. MongoDB for Windows
  7. MongoDB Compass

YARN Commands

  1. yarn -v (check version of YARN)
  2. cd realtime-salad-app (to work in the project folder)
  3. yarn init (Initializes package.json file in root of project)
  4. yarn add express ejs express-ejs-layouts (The above command performs 4 tasks-)
    • Writes dependencies to package.json,
    • Downloads express, ejs and express-ejs-layouts dependencies from there respective repositories on the Cloud,
    • Adds node_modules folder, which contains all the dependencies like a Tree structure, and
    • Creates yarn.lock file, which locks down the versions of the dependencies specified in the package.json file.
  5. yarn add nodemon -D (downloads nodemon that automatically restarts the server on any changes in the project & adds nodemon to devDependencies in package.json)
  6. yarn dev (runs the server)
  7. yarn add laravel-mix -D (downloads Laravel Mix, updates node_modules & adds laravel to devDependencies in package.json)
  8. yarn add cross-env --save-dev (to handle different environments)
  9. yarn watch (performs the following tasks -)
    • installs sass, sass-loader & resolve-url-loader dependencies when executed first time, and saves to package.json.
    • compiles SCSS & JS files using laravel-mix, and stores the compiled code to public folder i.e. CSS & JS.
  10. yarn add mongoose (helps in interaction of JS code with MongoDB)
  11. yarn add express-session (helps in storing sessions in key-value form)
  12. yarn add dotenv (a zero-dependency module that loads environment variables from a .env file into process.env)
  13. yarn add express-flash (used to flash messages for the application)
  14. yarn add axios (promise based HTTP client for the browser and node.js)
  15. yarn add noty (notification library that makes it easy to create alert, success, error, warning, information and confirmation messages)
  16. yarn add bcrypt (A library which helps in hashing passwords)
  17. yarn add passport passport-local (Authentication)

NPM Commands

NPM package manager is automatically downloaded with NodeJS, and it can be used as an alternative to YARN. Since NPM has a drawback that it works quite slow when compared with YARN (as YARN installs dependencies simultaneously), I will be using YARN in this project. However, I am providing NPM commands as well for reference.

  1. npm -v
  2. cd realtime-salad-app
  3. npm init
  4. npm install express ejs express-ejs-layouts
  5. npm install nodemon --save-dev
  6. npm run dev
  7. npm install laravel-mix --save-dev
  8. npm install cross-env --save-dev
  9. npm run watch
  10. npm install mongoose
  11. npm install express-session
  12. npm install dotenv
  13. npm install express-flash
  14. npm install axios
  15. npm install noty
  16. npm install bcrypt
  17. npm install passport passport-local

GIT Commands

  1\. git --version (checks version)
  2\. git init (creates .git file )
  3\. git status (to check if files are committed or not)
  4\. git add . (adds all files, ready to commit)
  5\. git commit -m "commit message here"
  6\. git push origin master -f (pushing all changes to github; -f stands for forced push)
  7\. git status (recheck files)
  8\. [.gitignore commands](https://stackoverflow.com/questions/12501324/how-to-use-gitignore-command-in-git)
  9\. [.gitignore for NodeJS guide](https://github.com/github/gitignore/blob/master/Node.gitignore)

Why use Laravel Mix?

  • A tool used to compile resources like modern JavaScript and SCSS code and store it to the public folder in JS and CSS format.
  • Advantage over other tools - avoids manual configuration (internally uses WebPack).
  • Works inside Laravel framework usually, but has an benefit that it can be used in Stand Alone projects like this one.
  • Laravel Guide

webpack.mix.js

  • A configuration file downloaded to node_modules while installing Laravel Mix.
  • Copy this file from node_modules to the root of project directory using the command given below.
  • cp node_modules/laravel-mix/setup/webpack.mix.js ./ (use copy in case of Windows OS)
  • This file imports laravel-mix module, and uses the methods js() & sass() for compilation and then storing of the compiled files.

Scripts in package.json

  • Update scripts in package.json file to compile these files.
  • The watch command automatically compiles the file everytime it is changed, eliminating the need to manually compile repeatedly.
  • cross-env : Runs Scripts that set and use environment variables across platforms (useful in production).

layout.ejs

  • An ejs file that serves the common content such as header, footer and nav bar to all the pages in the application.
  • Code in other ejs files like home, login and register, is simply embedded using <%- body%> after the nav bar.

Session Configuration

  • Done using express-session module, needed to store Cart data in this project.
  • The server creates & stores a session ID (sid) when a new client Requests for the web page.
  • Then it sends a message in Response header, which has sid, asking the client to create a cookie using that session id.
  • For every next request header from client, the cookie will be send to server, so that the server can recognize the client as an existing one.

Express Methods (Assets)

Built-in middleware functions in Express.

Database Connectivity - MongoDB, NodeJS & Mongoose

  • Mongoose is an Object Data Modeling library, that provides object mapping between MongoDB and NodeJS.
  • Connection is established using mongoose.connect() for single connection, or mongoose.createConnection() for multiple connections.
  • A Schema helps in defining the fields stored in each document along with their validation requirements and default values.
  • The timestamps parameter helps to add createdAt and updatedAt properties automatically to the particular document in the collection.
  • Schemas are then “compiled” into Models using the mongoose.model() method.
    • const MyModel = mongoose.model('ModelName', mySchemaName);
    • The first argument is the singular name of the collection your model is for. Mongoose automatically looks for the plural version of your model name.
  • Mongoose exists() method
  • Mongoose findById() method
  • Mongoose findOne() method

Hashing Passwords using bcrypt library

Using bcrypt is a secured way to store passwords in a database regardless of whatever language the app’s backend is built in — PHP, Ruby, Python, Node.js.

const bcrpyt = require("bcrypt")
const hashedPassword = await bcrpyt.hash(password, 10)

Passport - authentication middleware for Node.js

  • passport-local is a passport strategy for authenticating with a username and password.
  • Usage/Configuration
  • Middlewares
    • passport.initialize()
    • passport.session()
  • Passport will serialize and deserialize user instances to and from the session using:
    • passport.serializeUser()
    • passport.deserializeUser()

Is Full-Stack Developer A Vaccine For Startups?

There's a wise old saying: "Working with a full stack developer can lead to better technology solutions." And in recent years, this saying has proven to be true for many startups.

In the last few years, we have heard a lot about full-stack developers.

We know that a full-stack developer is a person who has complete knowledge of the different layers involved in application development. Whether you are dealing with the front or back end or working in the business layer, they take care of everything with ease.

But did you wonder why a full-stack developer is so important for a startup? 

This blog will answer all such queries. So let's get started.

The Demand for Full-Stack Developers

As per a development report published recently, it was seen that there had been a 206% increase in demand for full-stack developers from 2018 to 2020. This is because more companies seek multifaceted skills. 


Full-stack developers or a full-stack development company are able to take care of all the development needs of your project. So whether it's front-end or back-end development or enterprise layer development, they are competent to work on everything. You can always hire full-stack developers for your business needs.

What can a Full-Stack Developer Do?

In terms of software development, there are front-end developers and back-end developers. Front-end developers create the interface, while backend developers design the software. 

A full-stack developer can do everything. They take care of application design, server-side scripting, client-side coding, coding, administration, database creation, and any other project development needs.

The following are the responsibilities of a full stack developer that you hire:

  • Manage web development

  • Code applications and programs

  • Solve problems

  • Coordinate with other team members and developers

  • Think about testing techniques for web applications

In short, a full-stack developer has a strong understanding of the technologies that determine how a website looks, functions, and functions. The said developer must have a working knowledge of HTML, JavaScript, CSS, PHP, Angular, Ruby, MySQL, Node, MongoDB, Apache, etc. The knowledge to work with animations and design will add a bonus point to a candidate's portfolio.

Over time, the skills required for full-stack development have expanded and evolved. Long ago, the LAMP stack included Linux, Apache, MySQL, and PHP. It is more than MEAN and beyond today. 

Currently, a typical mean stack development service provides developers who can perform front-end development using JavaScript, HTML, CSS, and other JS frameworks; for the backend, they use Express and Node, and for databases, they follow MySQL and MongoDB.

Top Reasons to Hire Full-Stack Developers

  • Effective troubleshooting

When hiring a full-stack developer, companies are always looking for candidates who are capable of solving a problem. Full-stack developers are competent to handle all aspects of the project. They prove to be a practical solution for startups that are not willing to spend more money on many developers.

  • Wide range of technology skills

The main reason companies choose full-stack developers for their projects is their potential rather than their knowledge. Over time, companies teach them the skills they want them to have. In this way, in a few years, they learn different technological skills as the company expands.

  • Executive and management skills

Companies like to have people with business experience on board. A full-stack developer has the knowledge and expertise to work on the front-end, backend, and media architecture layers. This means that they are capable of performing better than an individual front-end or backend developer.

  • Economic

As full-stack developers can develop all aspects of a project, it is not necessary to form a team of experts. They will easily handle the project without help from anyone. This will save the right amount of money for the recruiting team.

  • Faster development process

Full-stack developers know different technologies, tools, and techniques. This means that when they take the project, they will be able to complete it faster. They will spend less time discussing and collaborating with the team on the project.

Benefits of Full-Stack Developers for Startups and Small Businesses

  • Established developers

Full-stack developers have enough experience to create outstanding features for the final product, which will be able to excite the market. They have the ability to build a complete product from scratch. If you want to gain some benefits from your product, you will have to collaborate with these experts. Remember that not all developers are capable of handling the project from a 360-degree perspective.

  • Versatility

A full-stack developer is able to work equally well on the front-end and the backend of a website or application. Front-end developers write code using JavaScript, HTML, and CSS, which are able to control the appearance of the solution and how it interacts with the browser and users. Backend developers write code that connects the website or application with other content management systems. A full-stack developer is capable of handling both tasks. They are focused on meeting customer expectations and finding solutions on their own.

 

  • Vast experience

Full-stack developers take on different web projects. This has helped them gain in-depth knowledge of various technologies and the experience to find quick solutions in web and application development. Such understanding and knowledge improve the performance of the project and its reception in the market.

  • The largest photograph

The main advantage of choosing a full-stack developer for your project is that they will come up with the complete structure of the project and offer their valuable input to the project as needed. Their services go beyond project development to maintain and optimize existing solutions.

  • Upgrades

Web design plays a crucial role in whether most people love or reject a website. Full-stack developers will make sure that the website is pretty user-friendly. They keep up with trends and technological innovations. To make sure their clients get the best interactive and responsive website, the developers implement intelligent features in their projects.

  • Troubleshooting issues

Full-stack developers have complete knowledge and experience of the different stages and aspects of website development. They are skilled enough to identify problems that may arise during the development of the project. They will propose long-term solutions to ensure that the website or application works optimally based on their findings.

  • All-inclusive

In addition to leading your web project and enabling enhancements to it, full-stack developers move to the level of representing your product to stakeholders or your company at conferences. They can move quickly from one operation to another with ease, streamlining the development process.

  • Economic

If you are on a tight budget but want to create a fantastic website, then you should consider hiring full developers for the job. You can even think about having a remote full-stack developer for the project. As such, a developer is capable of handling all aspects of project development; you won't have to hire different people for the job. This will save you a lot of money.

  • Delivery time

It will be easy for developers to share responsibilities among the team and coordinate with each other for better project progress. This will result in faster delivery of the project.

  • Project ownership

When you hire full-stack developers for your project, you can be sure that they will take care of everything. Such a developer will be able to develop MVP from start to finish. If you hire a full-stack developer in the middle of the project, even then, you'll find a way to join the flow seamlessly. Such a developer will work towards quality control of the design project.

 

 

Summing Up

So these were the advantages of hiring a full-stack developer. I hope you have noted the changes that a full-stack developer can bring to the table and in your company. However, working with a full-stack developer is the best way to work with a top full-stack development company in India.

Authentication In MEAN Stack - A Quick Guide

I consider myself an active StackOverflow user, despite my activity tends to vary depending on my daily workload. I enjoy answering questions with angular tag and I always try to create some working example to prove correctness of my answers.

To create angular demo I usually use either plunker or stackblitz or even jsfiddle. I like all of them but when I run into some errors I want to have a little bit more usable tool to undestand what’s going on.

Many people who ask questions on stackoverflow don’t want to isolate the problem and prepare minimal reproduction so they usually post all code to their questions on SO. They also tend to be not accurate and make a lot of mistakes in template syntax. To not waste a lot of time investigating where the error comes from I tried to create a tool that will help me to quickly find what causes the problem.

Angular demo runner
Online angular editor for building demo.

Let me show what I mean…

There are template parser errors that can be easy catched by stackblitz
