Angular: Setting up Routing

Introduction

Routing is one of the most important aspects of modern web development. Routing allows us to navigate between pages or views, creating a seamless user experience. In this tutorial, we'll be discussing how to set up routing in an Angular application.

Prerequisites

• Basic knowledge of Angular
• Angular CLI installed

Syntax

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { ComponentName } from './path/to/component';

const routes: Routes = [
  { path: '', component: ComponentName },
];

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

Example

Here is an example of how to set up routing in an Angular application:

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { HomeComponent } from './home/home.component';
import { LoginComponent } from './login/login.component';
import { ProfileComponent } from './profile/profile.component';

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'login', component: LoginComponent },
  { path: 'profile', component: ProfileComponent },
];

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

Explanation

In the above example, we first import the Routes and RouterModule from the @angular/router package. We then define the routes we want to use in our application. Each route is defined as an object with a path and component. The path is the URL to match, while component is the component to load when the URL is matched.

In our example, we have three routes:

• / maps to the HomeComponent
• /login maps to the LoginComponent
• /profile maps to the ProfileComponent

Finally, we import the RouterModule and configure the routes using the forRoot() method of RouterModule.

Use

Routing is a powerful feature of Angular and can be used to create Single Page Applications (SPAs) with various pages or views. It helps developers to maintain multiple views in a single application.

Important Points

• Routes are defined as an array of objects in Angular applications
• Each route object has a path and component property
• The path property is the URL to match, while the component property is the component to load when that URL is matched.
• Nested routing enables developers to have child routes, which are basically routes defined inside another route.

Summary

Routing is a crucial part of modern web development, and Angular makes it really easy to set up routing in your application. In this tutorial, we've gone over the syntax and explained how to use routing in Angular. We've also covered important points to keep in mind while configuring routing in Angular.
