How To Make Login Page In Angular

Web Development Software

Creating a login page in Angular is a crucial step in building a secure and user-friendly web application. As a web developer, I have had the opportunity to work on numerous projects that required implementing login functionality. In this article, I will guide you through the process of creating a login page using Angular, while also providing personal insights and commentary along the way.

Getting Started

Before diving into the code, make sure you have Angular CLI installed on your system. If you haven’t installed it yet, simply open your terminal and run the following command:

npm install -g @angular/cli

Once Angular CLI is installed, you can create a new Angular project using the following command:

ng new my-login-app

Navigate to the project directory:

cd my-login-app

Now that we have our project set up, let’s create the login page component. Run the following command to generate a new component called ‘login’:

ng generate component login

This will create a new folder called ‘login’ inside the ‘src/app’ directory, containing the necessary files for our login page component.

Building the Login Page

Open the ‘login.component.html’ file located inside the ‘src/app/login’ folder. This is where we will define the HTML structure of our login page.

Start by adding a form element with the ‘ngForm’ directive to handle form submission:

<form (ngSubmit)="login()" #loginForm="ngForm">

Inside the form, let’s add two input fields for the user to enter their username and password:

<input type="text" name="username" [(ngModel)]="username" required>
<input type="password" name="password" [(ngModel)]="password" required>

Next, include a button to submit the login form:

<button type="submit">Login</button>

Finally, close the form element:


Implementing the Login Logic

Now that we have our login page structure in place, let’s add the necessary code to handle form submission and authentication logic.

Open the ‘login.component.ts’ file located inside the ‘src/app/login’ folder. This is where we will write our TypeScript code.

First, let’s import the necessary modules and services:

import { Component } from '@angular/core';
import { NgForm } from '@angular/forms';

Inside the LoginComponent class, define the ‘username’ and ‘password’ properties:

username: string;
password: string;

Next, add the ‘login()’ method to handle form submission:

login() {
// Add authentication logic here

For simplicity, let’s assume we have a mock authentication service that checks if the entered username and password are valid:

login() {
if (this.authService.authenticate(this.username, this.password)) {
// Redirect to home page
} else {
// Display error message

Don’t forget to import the AuthService and inject it into the constructor:

import { AuthService } from '../auth.service';
constructor(private authService: AuthService) {}

With the login logic implemented, our login page is now ready to be tested.


Creating a login page in Angular is a fundamental step in building a secure web application. By following the steps outlined in this article, you can create a login page that allows users to authenticate and access protected resources. Remember to handle form submission, implement authentication logic, and provide appropriate feedback to the user. Happy coding!
