Screenshot

Set-up

$ mkdir fullstack-like-page
$ cd fullstack-like-page
$ irongenerate server
$ npx create-react-app client
$ code .

Server side: Rest API

The goal: create 2 endpoints (routes)

• GET /api/likes: To get all likes (JSON)
• POST /api/likes: To add one like (JSON)

Model:

• Like
  • name: String
  • createdAt: String

To run the back-end:

$ cd server
$ npm run dev-windows

To test the API, we will use Postman:

• GET http://localhost:5000/api/likes
• POST http://localhost:5000/api/likes (BODY => name:Alice)

Client side: React Application

Install axios in the client project

$ cd client
$ npm install axios

To run the front-end:

$ cd client
$ npm start

To solve CORS issues

$ cd server
$ npm install cors

// server/app.js

// ...
const cors = require('cors')
const app = express()

app.use(cors({
  origin: (origin, cb) => {
    cb(null, origin && origin.startsWith('http://localhost:'))
  },
  optionsSuccessStatus: 200,
  credentials: true
}))
// ...
