Integrating React, Vue, or Angular with Rails Tutorial

1. Introduction

• This tutorial aims to demonstrate how to integrate frontend frameworks such as React, Vue, or Angular with Rails. By integrating these frameworks, you can maintain complex user interfaces and accelerate the development process.
• You will learn how to set up and integrate React, Vue, and Angular with Rails. You will also understand the benefits of using these frameworks with Rails.
• Prerequisites: Basic understanding of Rails, JavaScript, and one of the mentioned frontend frameworks.

2. Step-by-Step Guide

Integrating React with Rails

• Concept: Rails supports React out of the box thanks to the webpacker gem. You can create a new Rails application with React configured by using the --webpack=react flag.
• Steps:
• Run rails new myapp --webpack=react to create a new Rails app with React.
• Navigate to your new Rails app: cd myapp.
• Start the Rails server: rails s.

Integrating Vue with Rails

• Concept: Similar to React, Rails also supports Vue out of the box.
• Steps:
• Run rails new myapp --webpack=vue to create a new Rails app with Vue.
• Navigate to your new Rails app: cd myapp.
• Start the Rails server: rails s.

Integrating Angular with Rails

• Concept: Angular integration with Rails is a bit different. You need to create separate applications for Rails (as API) and Angular, then connect them.
• Steps:
• Create a new Rails API: rails new myapp --api.
• Navigate to your Rails API: cd myapp.
• Start the Rails server: rails s -p 3001.
• Create a new Angular app: ng new myapp.
• Navigate to your Angular app: cd myapp.
• Start the Angular server: ng serve.

3. Code Examples

Creating a React Component in Rails

// app/javascript/components/HelloReact.js
import React from 'react';

const HelloReact = () => (
  <div>
    <h1>Hello, React!</h1>
  </div>
);

export default HelloReact;

• This code creates a simple React component that displays "Hello, React!". You can use this component in your Rails views.

Creating a Vue Component in Rails

// app/javascript/app.vue
<template>
  <div id="app">
    <h1>Hello, Vue!</h1>
  </div>
</template>

<script>
export default {
  name: 'app',
};
</script>

• This code creates a simple Vue component that displays "Hello, Vue!". You can use this component in your Rails views.

Creating an Angular Component

// src/app/app.component.ts
import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: `<h1>Hello, Angular!</h1>`,
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'myapp';
}

• This code creates a simple Angular component that displays "Hello, Angular!". You can use this component in your Angular application.

4. Summary

• You've learned how to integrate React, Vue, and Angular with Rails.
• For further learning, explore how to make API requests from these frameworks to Rails and how to deploy these applications.
• Some resources to help you:
• React on Rails
• Vue on Rails
• Angular on Rails

5. Practice Exercises

• Exercise 1: Create a Rails application with React and display a list of items.
• Exercise 2: Create a Rails application with Vue and add CRUD operations.
• Exercise 3: Create a Rails API and an Angular application. Connect them to display a list of items.

Solutions
- Solutions can be found in the official documentation of each framework and Rails. Make sure to understand how data flow works in these frameworks and how to make API requests. Keep practicing by creating different types of applications.
