Create HTTP Get and HTTP Post Server using Nodejs and express

For creating Http Get or Http Post Server using Nodejs (Not consuming Get or Post) Follow instructions below:

First Create a Nodejs project by running:

npm init -y

Then install express and body-parser dependencies by running

npm i express body-parser

Now create and edit the index.js file and add below code for serving Get & Post requests:

const express = require("express");
const bodyParser = require("body-parser");
const router = express.Router();
const app = express();
// add router in express app
app.use("/", router);
app.use(bodyParser.urlencoded({extended: false}));
app.use(bodyParser.json());
//sample Get Server
router.get('/', function (req, res) {
  res.send('hello world')
});
//sample Post Server
router.post('/', (req, res) => {
    req.on('data', function (data) {
        res.writeHead("200", "OK");
        res.end("end");
        console.log("Getting JSON!")
        let result = JSON.parse(data.toString());
        console.log(data.toString());
  })
});
app.listen(6000, () => {
    console.log("Started on PORT 6000");
})

For running the code just simply run:

node index.js

Then you can test your code by calling curl commands:

curl http://localhost:6000

curl –request POST ‘http://localhost:6000’ \
–header ‘Accept: application/json’ \
–header ‘Content-Type: text/plain’ \
–data-raw ‘{“id”: “1”}’
