React Flask Authentication

Open-source full-stack seed project that uses a React UI powered by a simple Flask API Server. React Flask Authentication sample can be used to bootstrap fast a new project using a tested development-ready stack or simply for eLearning purposes by beginners. For newcomers, React is a popular Javascript library for coding user interfaces baked by Facebook and Flask is a leading web framework written in Python.

✨ Start the Flask API via Docker

$ cd api-server-flask
$ docker-compose up --build  # Start with Docker

At this point, the API should be up & running at http://localhost:5000, and we can test the interface using POSTMAN or curl.

✨ Start the React UI (use another terminal)

👉 Step 1 - Once the project is downloaded, change the directory to react-ui.

$ cd react-ui

👉 Step 2 - Install dependencies via NPM or yarn

$ npm i
// OR
$ yarn

👉 Step 3 - Start in development mode

$ npm run start 
// OR
$ yarn start

Once all the above commands are executed, the React UI should be visible in the browser. By default, the app redirects the guest users to authenticate. After we register a new user and signIN, all the private pages become accessible.

✨ General Information

The product is built using a two-tier pattern where the React frontend is decoupled logically and physically from the API backend. In order to use the product in a local environment, a few simple steps are required:

• Compile and start the Flask API Backend
  • be default the server starts on port 5000
• Compile and start the React UI
  • UI will start on port 3000 and expects a running backend on port 5000
• Configuration (Optional)
  • Change the API port
  • Configure the API port used by the React UI to communicate with the backend

✨ Manual build

👉 Start the Flask API

$ cd api-server-flask
$ 
$ # Create a virtual environment
$ virtualenv env
$ source env/bin/activate
$
$ # Install modules
$ pip install -r requirements.txt
$
$ # Set Up the Environment
$ export FLASK_APP=run.py
$ export FLASK_ENV=development
$ 
$ # Start the API
$ flask run 

👉 Compile & start the React UI

$ cd react-ui
$
$ # Install Modules
$ yarn
$
$ # Start for development (LIVE Reload)
$ yarn start 

Configuration (Optional)

Change the port exposed by the Flask API

$ flask run --port 5001

Now, the API can be accessed on port 5001

Update the API port used by the React Frontend

API Server URL - src/config/constant.js

const config = {
    ...
    API_SERVER: 'http://localhost:5000/api/'  // <-- The magic line
};

✨ API

For a fast set up, this POSTMAN definition can be used.

Register - api/users/register (POST request)

POST api/users/register
Content-Type: application/json

{
    "username":"test",
    "password":"pass", 
    "email":"[email protected]"
}

Login - api/users/login (POST request)

POST /api/users/login
Content-Type: application/json

{
    "password":"pass", 
    "email":"[email protected]"
}

Logout - api/users/logout (POST request)

POST api/users/logout
Content-Type: application/json
authorization: JWT_TOKEN (returned by Login request)

{
    "token":"JWT_TOKEN"
}
