how to start writing API request

In order to request data from API, we need to set up an express to do get request

npm install express
create file name index.js for my main server foler
const express = require('express')
to call express
const db = require('../databasefolder')
call db folder & file
start express by writing
const app = express();
const port = 1004;

port can be any 4 digit numbers

app.listen(port, () => console.log(Successfully connected to the port ${port}))
write your get, put, post requests

ex.

app.get('/products', (req, res) => {
  let { page, count } = req.query;
  if (page === undefined) {
    page = 0;
  };
  if (count === undefined) {
    count = 5;
  };
  db.getProducts(page, count, (err, result) => {
    if (err) {
      res.status(400)
      console.log(err);
    }
    res.status(200)
    res.send(result);
  })
});

app.get('/products/:product_id', (req, res) => {
  const { product_id } = req.params;
  db.getCurrentProduct(product_id, (err, result) => {
    if (err) {
      res.status(400)
      console.log(err);
    }
    res.status(200)
    res.send(result);
  })
});
