This may be a good start to understand how to trigger API calls from Js
fetch('https://reqres.in/api/deleteUser', {
method: "DELETE",
headers: {
'Content-type': 'application/json'
},
body: JSON.stringify({
id: '1'
})
})
.then(res => {
if (res.ok) { console.log("HTTP request successful") }
else { console.log("HTTP request unsuccessful") }
return res
})
.then(res => res.json())
.then(data => console.log(data))
.catch(error => console.log(error))
And then for NodeJs
// Module dependencies
var express = require('express'),
ejs = require('ejs'),
fs = require('fs'),
mysql = require('mysql');
// Application initialization
var connection = mysql.createConnection({
host : 'localhost',
user : 'root',
password : '' //<your password
});
var app = module.exports = express.createServer();
// Database setup
connection.query('CREATE DATABASE IF NOT EXISTS test', function (err) {
if (err) throw err;
connection.query('USE test', function (err) {
if (err) throw err;
connection.query('CREATE TABLE IF NOT EXISTS users('
+ 'id INT NOT NULL AUTO_INCREMENT,'
+ 'PRIMARY KEY(id),'
+ 'name VARCHAR(30)'
+ ')', function (err) {
if (err) throw err;
});
});
});
// Configuration
app.use(express.bodyParser());
// Post delete user
app.post('/deleteUser', function(req, res) {
var id=Number(req.query.id);
console.log(id);
connection.query('delete from users where id='+id,
});
