Building a ‍Task ⁤Management App with Rails ⁢and React



Task management‌ is​ a ​critical⁢ aspect⁢ of ⁤any⁢ project⁤ or organization.⁣ With ⁤the‍ rise of web ⁣technologies, ‌it has⁤ become‍ essential ⁣to ⁢develop⁤ task‍ management ⁣applications⁤ that are ⁣efficient, user-friendly, ‌and ⁣provide⁢ real-time​ updates.⁣ In this tutorial, we will⁢ explore ​the process of ‍building a task​ management app using the​ popular ⁤web development ⁤frameworks, Ruby⁢ on ‍Rails⁤ and ⁤React.



Prerequisites



​ ​

Before​ we begin, ⁣make⁣ sure⁢ you have ⁤the ​following⁢ installed:



    ‍ ‍ ​

  1. Ruby on⁤ Rails: The framework that ‌will​ handle our ⁢backend logic.
  2. ​​

  3. PostgreSQL:⁣ A‍ powerful open-source database that ⁤integrates‍ seamlessly with Rails.


  4. ⁢ ⁤ ‍

  5. Node.js:⁤ A⁣ JavaScript runtime⁢ environment to execute⁢ our React code.


  6. React:⁣ A‌ JavaScript library‌ for building⁣ user interfaces.



Setting ‍Up the⁣ Rails ⁣Backend

First, let’s ⁢create a new Rails application:



⁢ ‍ ‍
⁤ ‌ ​ ‌ ‍$‍ rails ⁢new task-management-app
‌ ⁢ ⁤ $​ cd task-management-app



⁣ ⁣

Next,‌ we need ‌to‍ generate⁢ a ⁢model‍ and controller⁢ for managing⁢ tasks:

⁤⁣


‌‌ ​
⁤ ⁣$ ​rails generate model‌ Task ⁢name:string description:text​ completed:boolean
‌ ⁣ ​ ‌ ⁣$ ⁤rails‌ generate ‍controller Tasks⁣ index create⁣ update destroy
​ ​ ⁣

​ ⁤




‍ ⁤

Now, let’s‌ create‌ the ⁢necessary routes in the​ config/routes.rb⁤ file:


​ ⁣⁢
⁣ ⁣⁤ ⁣ ​Rails.application.routes.draw do
⁣ ⁣ ⁤ ⁣ ​ ‍resources :tasks, only: [:index, :create, ⁤:update, :destroy]
‌ ​ ‍ ⁣ ​ ⁢ root​ 'tasks#index' ​ ​ end



Implementing​ the⁤ React⁢ Frontend



Now,‌ let’s ‌set ⁤up the React frontend of ⁤our⁣ task management⁣ app.⁤ We⁣ will⁤ use Create React App⁣ to ⁣quickly ⁤scaffold ​our​ React⁣ application:



‍ ⁤
​ ‍ $​ npx create-react-app frontend
⁣ ‍ ‌ ⁢ ‍ $⁣ cd frontend




⁢ ⁢

Modify ⁣the⁣ src/App.js‍ file ⁤to include our task management ⁣logic:


 ⁢ ⁣ ‍ ‌
  ⁤‍ ‍ ‍  ‍import React, ⁣{​ useState, ​useEffect⁤ } ​from 'react';
⁢ ⁤ ​ import‍ axios from 'axios'; ⁢ ‍ ‌ ‌ ‍ function ​App() ‌{
⁢ ‌ ‌⁢ ‌const [tasks,‌ setTasks] ‍=‌ useState([]); ‌ ⁣ ​⁣ ⁤ const [newTaskName, setNewTaskName]⁣ = ⁢useState('');

⁤ ⁢ ​ ⁤ useEffect(()‌ => { ‍ ⁣ ​ ​fetchTasks();
⁢​ ⁢ ⁣ },‌ []); ⁤ const⁤ fetchTasks ‍= async ⁢() => ⁣{
⁣⁤ ‌ ​ ⁣const ‍response‌ = ‍await axios.get('/tasks');
⁤‌ ⁤ ⁣ setTasks(response.data);
‍ ​‌ ‍⁣ ⁣ };
⁢ ‌⁣ ‍ ⁣ ⁤const createTask‌ = async () => { ‍ ⁤ ​ ‌⁣ await⁣ axios.post('/tasks', {‍ name: ​newTaskName });
​ ​​ ⁣ ‍ ‌‍ ⁣setNewTaskName(''); ⁣ ‍ ‍ ⁣ ⁣ ​ ‍⁤ ⁤fetchTasks();
‌ ⁤ ⁣ ⁣​ ⁣ ‍};

‌ ​ return ​(
⁤ ‌​ ⁤

​ ‍ ⁣ ⁢ ⁢ ⁤​ ‌ ⁢

Task ⁤Management‌ App

⁤ ‌ ‌ ⁤⁢ ​‌ ⁢ ​ ⁣ ⁣ ⁢ ‍⁢ type="text"
⁤ ⁢⁢ ​ ⁢ ‍ ‌ value={newTaskName}
⁣ ​ ⁢ ⁤ ​‌ ‌ ‍ onChange={(e) => ⁢setNewTaskName(e.target.value)}
​ ​ ‍⁢ ⁢ ​ />
⁣ ⁣ ⁣ ⁣ ​⁣ ⁢ ⁣
‌ ⁢ ‍ ‌ ⁤⁣

    ⁢ ​ ⁢ ⁤ ​⁤ ‌ ⁤ {tasks.map((task) => ⁤( ​ ‌⁣ ‌ ⁣ ‍ ‌ ⁣ {task.name}
    ‍ ​ ⁢ ⁣ ‌ ))}
    ⁢ ​ ⁢ ​ ‍ ‍ ⁢

⁢ ⁤ ⁣ ‍⁣ ‍ ⁢
‌ ⁢⁢ ​ ‌ );
​ ⁤ }
‍ ‌ ⁢ export default​ App;
⁤ ⁢

⁢ ⁣


⁢⁢

Connecting​ the Backend ‍and Frontend

Now that⁤ we⁣ have set​ up both ⁤the‌ Rails backend ‌and ​React⁣ frontend, ⁣we⁤ need to connect ​them​ together. In the‌ config/initializers/cors.rb⁢ file, uncomment the following⁤ line ⁢to allow cross-origin ⁣requests:



⁢ ‌
​ ⁣ ‍ ⁣ Rails.application.config.middleware.insert_before 0, Rack::Cors⁤ do
‌ ​ ⁣ ⁤ allow do
⁤ ⁤ ‍ ⁢ ‌ origins⁣ '*'
‍ ⁢ ⁤resource '*', headers: :any, methods:⁣ [:get,‍ :post, ​:put, ‍:delete] ​ ​ ‌ ⁢ ‍⁢ end
‍‍ ⁤‌ end



⁢ ​

Finally, ​let’s⁤ run ‍our application:



‌ ⁢ ⁣ ⁣ # Terminal ‍Tab 1 ⁤- Start Rails backend
⁢ ⁢‍ ⁣ ​$ cd task-management-app
⁤ ‌ ‍ $ rails s

​ ⁣ ⁢ ⁣ # Terminal⁤ Tab‍ 2 -​ Start React frontend
‍ ‌ ‌ ‍$​ cd ‍frontend
‌ ⁤ ⁤ ​ $‍ npm‍ start
‌ ⁤ ⁣


Note: Make⁣ sure⁣ both Rails⁤ backend and React frontend are running concurrently ⁢for⁢ the app to⁤ function ​properly.

⁣ ‌

Conclusion


⁤ ​

Congratulations!⁤ You have ‌successfully built⁢ a ‍task management ⁣app using Rails​ and React. ⁤This application provides‍ a solid foundation⁢ that can ​be⁤ expanded ⁤with additional features like⁣ task ⁢editing,​ due ‌dates, ⁢priority levels,⁤ and⁢ user authentication.⁢ We hope ‌this tutorial ⁤has been helpful in ⁢understanding⁤ the ⁢integration of Rails ⁤and ​React to ​build ​modern web applications.
