How to Build a Full Stack App with AWS Amplify and React

AWS Amplify is a tool developed by Amazon Web Services that helps make app development easier.

It includes loads of features which allow you to quickly and easily work with other AWS services. This means you can spend more time building the features that make your app unique.

This tutorial is split into four parts:

How to create the app with login
How to add a database and work with the data
How to add file storage and use those files
How to allow users to upload their own files and data

How to Create the App with Signup, Login and Logout

In this first section we’ll be setting up a new React App with AWS Amplify to add Sign up, Login and Logout in the easiest way possible.

We need to start by creating a new React app using create-react-app. Open a terminal and run these commands. If you don’t have create-react app installed then you can run npm i -g create-react-app first.

npx create-react-app amplify-react-app

cd amplify-react-app

With that set up we can now install Amplify and then configure it.

npm install -g @aws-amplify/cli

amplify configure

This will open up an AWS console tab in your browser. Make sure that you’re logged into the correct account with a user that has admin permissions.

Go back to the terminal and follow the steps, adding a region and name for the user. This will then take you back the the browser where you can follow the steps to create the new user. Make sure to stay on the page where you see the key and secret!

Back in the terminal again you can follow the steps, copying the access key and secret into the terminal when asked. When you are asked if you want to add this to a profile say Yes. Create a profile that is something like serverless-amplify.

Now we can initialise the amplify setup by running amplify init. You can give the project a name and answer all the questions. Most of them should be correct already. This then takes a while to make the changes on your account.

Once done we need to add authentication to the app. We do this with amplify add auth. Select the method as default the sign in to email and then no, I am done. We can now deploy this by running amplify push. This takes a while but at the end, our src/aws-exports.js file has been created.

How to Build the React App

Now we can get onto creating the react app. Start by installing the Amplify npm packages we need.

npm install --save aws-amplify @aws-amplify/ui-react

Now we can start editing the code of our app. In our src/App.js file we can remove everything in the headers and replace it with this:

<header className="App-header">
    <AmplifySignOut />
    <h2>My App Content</h2>
</header>

This is a very basic set up but you could put the main content of your site here and put the AmplifySignOut button where ever you want it to be.

We also need to add some extra imports to the top of the file:

import Amplify from 'aws-amplify';
import awsconfig from './aws-exports';
import { AmplifySignOut, withAuthenticator } from '@aws-amplify/ui-react';

Amplify.configure(awsconfig);

Now the last thing that we need to do is to change the way that we export the app. Change the last line to be export default withAuthenticator(App); to add Amplify to this app.

Now when we run npm start we should get a login screen. We’ve not created this so it has come from Amplify itself.

If we try and log in then it will fail, as we need to sign up first. We can click create account and then enter our email and a password to sign up.

Once we’ve confirmed our email by submitting the code we were sent, we get onto the home page of our app. If we log out we can now log back in as expected.

How to Add a Database to our App

If you want to add data to your React app but don’t want to have to build an API, then this is the section for you. We’ll be having a look at how we can use AWS amplify inside our React app to allow us to access our database on the back end using GraphQL.

To start we need to go into the terminal and run:

amplify add api

This will start us in a set of CLI options, asking us a few configuration questions:

What kind of API we want to use: GraphQL

The name of the API: songAPI

How we want to authenticate the API: Amazon Cognito User Pool

Advanced Settings: No, I am done

Do you have a schema: No

What kind of schema do you want: Single object with fields

After a little setup we are asked if we want to edit our new schema. We want to say yes. This opens the GraphQL schema which we’re going to update to be the schema listed here.

type Song @model {
    id: ID!
    title: String!
    description: String!
    filePath: String!
    likes: Int!
    owner: String!
}

With our schema set up we’re going to run amplify push which will compare our current amplify setup with that on our AWS account. As we’ve added a new API we’ll have changes, so we will be asked if we want to continue with the changes.

Once we’ve selected Yes then we’re put into another set of options.

Do we want to generate code for our GraphQL API: Yes

Which Language: JavaScript

File pattern for the new files: src/graphql//*.js**

Generate all operations: Yes

Maximum statement depth: 2

This will now deploy all of the changes to AWS and also set up the new request files in our React app. This does take a few minutes to do.

Once that is completed we can go into our App.js file and rename it to be App.jsx. This just makes it easier to write our JSX code.

We now need to write a function in here to get the list of songs from our new database. This function calls the GraphQL API passing in the operation of listSongs. We also need to add a new state to the App component.

const [songs, setSongs] = useState([]);

const fetchSongs = async () => {
    try {
        const songData = await API.graphql(graphqlOperation(listSongs));
        const songList = songData.data.listSongs.items;
        console.log('song list', songList);
        setSongs(songList);
    } catch (error) {
        console.log('error on fetching songs', error);
    }
};

We now need to add or update a few imports to our file to get this working:

import React, { useState, useEffect } from 'react';
import { listSongs } from './graphql/queries';
import Amplify, { API, graphqlOperation } from 'aws-amplify';

The listSongs is one of those functions created by amplify to help us access our data. You can see the other functions that are available in the ./graphql folder.

Now we want this function to be called once when the component renders, but not every time that it re-renders. To do this we use useEffect but make sure to add a second parameter of [] so that it only gets triggered once.

useEffect(() => {
    fetchSongs();
}, []);

If we now start our app using npm start and then go to the app we can open the console and see a log of song list []. This means that the useEffect has called the fetchSongs which is console logging out the result, but currently there is nothing in the database.

To correct this we need to log into our AWS account and add the DynamoDB service. We should find a new table called something like Song-5gq8g8wh64w-dev. If you can’t find it make sure to check other regions as well.

This currently has no data so we need to add some. For now we’re going with manually creating new data in here. Under Items click Create item and then make sure the dropdown in the top left shows text. If it shows tree then just click it and change it to text. We can then make the data go into that row.

We start with the GraphQL schema, giving the row some data for each attribute. But we also need to add createdAt and updatedAt values. You can find this using the browser console.

Type new Date().toISOString() and copy the result of that. You should end up with an object like this:

{
  "id": "gr4334t4tog345ht35",
  "title": "My First Song",
  "description": "A test song for our amplify app",
  "owner": "Sam Williams",
  "filePath": "",
  "likes": 4,
  "createdAt": "2020-08-13T07:01:39.176Z",
  "updatedAt": "2020-08-13T07:01:39.176Z"
}

If we save that new object then we can go back into our app and refresh the page. We should now be able to see our data in the console.log.

We can now use this data in our app to show the list of songs that we just got. Replace the existing text of song list with this set of JSX.

<div className="songList">
    {songs.map((song, idx) => {
        return (
            <Paper variant="outlined" elevation={2} key={`song${idx}`}>
                <div className="songCard">
                    <IconButton aria-label="play">
                        <PlayArrowIcon />
                    </IconButton>
                    <div>
                        <div className="songTitle">{song.title}</div>
                        <div className="songOwner">{song.owner}</div>
                    </div>
                    <div>
                        <IconButton aria-label="like">
                            <FavoriteIcon />
                        </IconButton>
                        {song.likes}
                    </div>
                    <div className="songDescription">{song.description}</div>
                </div>
            </Paper>
        );
    })}
</div>

This code is mapping over each song in the list and rendering a new Paper for them with all the details we need.

We’re using the MaterialUI library to help make this look nice for us so we need to make sure to run npm install --save @material-ui/core @material-ui/icons to install those packages and then add them to the imports at the top of the file too:

import { Paper, IconButton } from '@material-ui/core';
import PlayArrowIcon from '@material-ui/icons/PlayArrow';
import FavoriteIcon from '@material-ui/icons/Favorite';

With this, if we save and reload our app we now get this:

Whilst this is ok, we can update the CSS to make it look far better. Open up your App.css file and change it to this:

.App {
    text-align: center;
}

.App-logo {
    height: 10vmin;
    pointer-events: none;
}

.App-header {
    background-color: #282c34;
    min-height: 5vh;
    display: flex;
    align-items: center;
    justify-content: space-around;
    font-size: calc(10px + 2vmin);
    color: white;
}

.App-link {
    color: #61dafb;
}

.songList {
    display: flex;
    flex-direction: column;
}

.songCard {
    display: flex;
    justify-content: space-around;
    padding: 5px;
}

.songTitle {
    font-weight: bold;
}

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

Performance: It delivers optimal performance.
Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
UI design: React Native enables you to design simple and responsive UI for your mobile app.
3rd party plugins: This framework supports 3rd party plugins.
Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
Near-native user experience: React Native provides several native components, and these are platform agnostic.
The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

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.

It is a good idea that full-stack development companies bring to your projects are phenomenal and groundbreaking due to the expertise and experience that full-stack development companies bring to your projects.

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research

_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.
