Datastore with AWS Amplify & React

Amplify DataStore provides a programming model for leveraging shared and distributed data without writing additional code for offline and online scenarios, which makes working with distributed, cross-user data just as simple as working with local-only data.

AWS Amplify is a JavaScript library for frontend and mobile developers building cloud-enabled applications

AWS Amplify provides a declarative and easy-to-use interface across different categories of cloud operations. AWS Amplify goes well with any JavaScript based frontend workflow, and React Native for mobile developers.

Our default implementation works with Amazon Web Services (AWS), but AWS Amplify is designed to be open and pluggable for any custom backend or service.

Real-Time Message Board With AWS Amplify & React

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.

How to Integrate AWS Amplify Authentication For React Native

This tutorial is going to take a look at one of the most important features of a mobile application — the authentication. You know the scenario. You need to store some amount of user information (credentials) for them to get back and re-use the application rather than creating a new account.

Please make sure to have an AWS account before you begin this tutorial. If you don’t, please sign up for one.

What is AWS Amplify?

Amazon Web Service is a technology that provides cloud services. Since its launch in 2017, Amplify has come a long way in terms of providing a set of services in the form of the toolchain. It is also open source.

To build authentication into a React Native and Expo application with Amplify you first need to install the AWS Amplify CLI. Open a terminal window and execute the command below to install the CLI. We are going to install it as a global module.

npm install -g @aws-amplify/cli

Using Amplify’s CLI tool you are going to find several really helpful CLI plugins and services that you can enable with one click when integrating with a framework like React Native. Services such as GraphQL and REST APIs, authentication UI as well as backend support, storage, hosting, and many more are made available by Amplify’s CLI.

Getting Started with React Native and AWS Amplify

Start by creating a new application project. We are going to Expo CLI to generate the project. Open a terminal window and create a new React Native app.

npx expo-cli init expo-amplify-example

This command creates a new directory called expo-amplify-example. You can name it whatever you want. Inside this directory, you are going to find a complete React Native + Expo SDK project generated. Please note that, on running the above command, you’ll be asked by the CLI which template to use. This tutorial uses a blank template from the managed workflow. If you are familiar with any other template, feel free to choose that.

Expo CLI is a command-line utility to create React Native apps with no build configuration. The reason we’re relying on it is that, first, it’s an awesome tool for such use cases.

Build fast and production ready apps with React and AWS Amplify

A little while ago I did a session for my friends at college for Student Developer Clubs (you can watch the session here). The topic we sunk in was React for Beginners. Towards the end of the session I built a Todo app with React and use React’s state to manage the todos.

I thought what if I could use the same front-end code for my an Amplify app!? So I started reading the documentation for Amplify and asked an experienced friend with Amplify to share some light on the topic.

So… Lets get this started and build the app. I suggest you guys to code as you read this piece of article.

What is amplify?

Amplify is an open-source framework that Amplify CLI, Libraries and UI Components to build fullstackk iOS, Android, Flutter, Web and React apps. It provides api, auth, functions, etc. That cater the needs of any application.

Amplify Console is an AWS service that provides a git-based workflow for continuous deployment & hosting of fullstack web apps.
