In this article, we would like to show you how to send the form from node server in Express.js.
To send the form from the node server using Express.js, we use the sendFile method on the response object.
Practical example
Project structure:
/C/

|
+-- server.js
server.js
const express = require('express');
const app = express();
app.get('/', (request, response) => {
const pathToFile = __dirname + '/loginForm.html'
response.sendFile(pathToFile);
});
app.post('/auth', (request, response) => {
const username = request.body.username;
const password = request.body.password;
// authentication
if (isCorrect) {
response.send('Success')
} else {
response.send('Incorrect Username and/or Password!');
}
}
app.listen(3000, () => {
console.log(`server is listening at http://localhost:3000`);
});
