Creating a Login function Using Express.js Part 1
Welcome to Part 1 of our tutorial series on creating a login function using Express.js. In this article, we will cover the basics of setting up our Express.js server and creating a simple login form.
Setting Up the Server
First, we need to set up a basic Express.js server. If you haven’t already installed Node.js and Express.js, you can do so by following the instructions on their respective websites.
Once you have Node.js and Express.js installed, create a new directory for your project and navigate to it in your terminal. Then, run the following commands to initialize a new Node.js project and install Express.js:
$ npm init -y
$ npm install express
Next, create a new file called app.js in your project directory. This will be the main file for our Express.js server. In app.js, add the following code to create a basic Express.js server:
const express = require('express');
const app = express();
const port = 3000;
app.listen(port, () => {
console.log(`Server is running on port ${port}`);
});
Now, if you run node app.js in your terminal, you should see a message indicating that your server is running on port 3000.
Creating a Login Form
Now that we have our server set up, let’s create a simple login form. In app.js, add a new route to handle the login form:
app.get('/login', (req, res) => {
res.send(`
Login
`);
});
app.post('/login', (req, res) => {
// Handle login logic here
});
In the above code, we created a new route for the /login URL, which will render a simple HTML form with fields for the username and password. We also added a POST route to handle form submissions, but we will implement the login logic in the next part of this tutorial.
And that’s it for Part 1! In the next part of this tutorial, we will focus on handling form submissions and implementing the login logic. Stay tuned for Part 2!
