Creating a login page in Angular 6 can seem like a daunting task, but with the right guidance and a little bit of patience, it can be a rewarding experience. In this article, I’ll guide you through the process of creating a login page in Angular 6, while adding personal touches and commentary along the way.
Getting Started
Before we dive into the code, let’s make sure we have everything set up properly. To create a login page in Angular 6, you’ll need to have Angular CLI installed on your machine. If you haven’t installed it yet, you can do so by running the following command:
npm install -g @angular/cli
Once you have Angular CLI installed, you can create a new Angular project by running the following command:
ng new login-page
This command will create a new Angular project called “login-page” in the current directory. Change directory to the newly created project folder:
cd login-page
Creating the Login Component
Now that we have our project set up, let’s create the login component. In Angular, a component is a reusable piece of code that represents a section of the user interface. To create a new component, run the following command:
ng generate component login
This command will create a new folder called “login” inside the “src/app” directory, along with the necessary files for the component. Open the newly created “login.component.ts” file and let’s start adding some code.
Inside the “login.component.ts” file, import the necessary classes and modules:
import { Component, OnInit } from '@angular/core';
Next, define the component class and implement the necessary methods:
@Component({
selector: 'app-login',
templateUrl: './login.component.html',
styleUrls: ['./login.component.css']
})
export class LoginComponent implements OnInit {
constructor() { }
ngOnInit() {
}
}
In the above code, we’ve defined the component class “LoginComponent” and implemented the “OnInit” interface, which provides a lifecycle hook called “ngOnInit”. This hook is invoked after Angular has initialized all the data-bound properties of the component.
Adding the HTML Template
Now that we have our component class set up, let’s add the HTML template for the login page. In the same directory as the “login.component.ts” file, create a new file called “login.component.html” and add the following code:
<h2>Login</h2>
<form>
<div>
<label for="username">Username</label>
<input type="text" id="username" [(ngModel)]="username">
</div>
<div>
<label for="password">Password</label>
<input type="password" id="password" [(ngModel)]="password">
</div>
<button type="submit">Login</button>
</form>
In the above code, we’ve created a simple login form with two input fields for the username and password, along with a submit button. The “[(ngModel)]” directive is used for two-way data binding, which allows us to bind the input values to the component properties.
Adding the CSS Styles
To add some styling to our login page, let’s create a CSS file for the component. In the same directory as the “login.component.ts” file, create a new file called “login.component.css” and add the following code:
h2 {
color: #333;
}
label {
display: block;
margin-bottom: 5px;
}
input {
width: 100%;
padding: 5px;
margin-bottom: 10px;
}
button {
padding: 10px 20px;
background-color: #333;
color: #fff;
border: none;
}
In the above code, we’ve added some basic CSS styles to the login page. Feel free to customize the styles to match your personal preferences.
Adding Routing
Now that we have our login component set up, let’s add routing to our application. Routing allows us to navigate between different components in our Angular application. Open the “app-routing.module.ts” file located in the “src/app” directory and add the following code:
import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { LoginComponent } from './login/login.component';
const routes: Routes = [
{ path: 'login', component: LoginComponent }
];
@NgModule({
imports: [RouterModule.forRoot(routes)],
exports: [RouterModule]
})
export class AppRoutingModule { }
In the above code, we’ve defined a route for our login component. Now, when we navigate to “/login” in our application, the login component will be rendered.
Conclusion
In this article, we explored the process of creating a login page in Angular 6. We started by setting up our development environment and creating a new Angular project. Then, we created a login component, added the necessary HTML template and CSS styles, and configured routing for our application.
With the knowledge gained from this article, you should now be able to create a login page in Angular 6 with ease. Feel free to add your personal touches and customize the login page to fit your specific needs.
Now, it’s time to put your skills to the test and create your own login page in Angular 6. Happy coding!
