How to create angular login register form step by step

Creating a login and register form in Angular involves multiple steps, including setting up your Angular application, creating components, setting up routing, and handling user authentication. Below is a step-by-step guide to creating a basic login and register form in Angular.

Step 1: Set Up Your Angular Application

Make sure you have Node.js and npm installed. Then, install the Angular CLI globally:

npm install -g @angular/cli

Create a new Angular application:

ng new angular-authentication

Navigate to the project directory:

cd angular-authentication

Step 2: Create Authentication Components

Create two components for the login and register forms:

ng generate component login
ng generate component register

Step 3: Set Up Routing

Edit the ‘app-routing.module.ts’ file to define the routes for your login and register components:

// app-routing.module.ts

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { LoginComponent } from './login/login.component';
import { RegisterComponent } from './register/register.component';

const routes: Routes = [
  { path: 'login', component: LoginComponent },
  { path: 'register', component: RegisterComponent },
  { path: '', redirectTo: '/login', pathMatch: 'full' },

  imports: [RouterModule.forRoot(routes)],
  exports: [RouterModule],
export class AppRoutingModule {}

Step 4: Create Login and Register Forms

Edit the HTML and TypeScript files of the ‘login’ and ‘register’ components (‘login.component.html’, ‘login.component.ts’, ‘register.component.html’, ‘register.component.ts’). Add form controls and validation as needed.

Example ‘login.component.html’:


Step 5: Implement Authentication Service

Create an authentication service that handles user authentication. You can use Angular services for this purpose:

ng generate service auth

Implement authentication logic in the auth.service.ts file.

Example ‘auth.service.ts’:

// auth.service.ts

import { Injectable } from '@angular/core';

  providedIn: 'root',
export class AuthService {
  constructor() {}

  login(username: string, password: string): boolean {
    // Implement login logic here
    return true; // Placeholder, replace with actual authentication logic

  register(username: string, password: string): boolean {
    // Implement registration logic here
    return true; // Placeholder, replace with actual registration logic

Step 6: Integrate Authentication Service with Components

Inject the ‘AuthService’ into the ‘login’ and ‘register’ components, and use it to handle user authentication.

Example ‘login.component.ts’:

// login.component.ts

import { Component } from '@angular/core';
import { AuthService } from '../auth.service';

  selector: 'app-login',
  templateUrl: './login.component.html',
  styleUrls: ['./login.component.css'],
export class LoginComponent {
  constructor(private authService: AuthService) {}

  onSubmit(username: string, password: string): void {
    if (this.authService.login(username, password)) {
      // Navigate to the home page or perform desired action
      console.log('Login successful');
    } else {
      console.log('Login failed');

Step 7: Update HTML with Form Binding

Update the HTML forms to bind to the corresponding component methods:


Repeat the same process for the ‘register’ component.

Step 8: Test Your Application

Run your Angular application:

ng serve

Visit http://localhost:4200 in your browser and navigate to the login and register pages.

Note: This is a basic example, and in a real-world scenario, you would use a server-side backend for authentication and securely store user credentials. Additionally, you may want to explore Angular forms, reactive forms, and form validation for a more robust solution.
