Getting started

The router in Aurelia 1 is a powerful and flexible system for managing navigation in your single-page applications (SPAs). It allows you to create a multi-view application with deep linking and powerful navigation features.

Here's a step-by-step guide to get you started with routing in Aurelia:

Set Up Your App Component

Your app component will serve as your application's main container and host the router.

In src/app.html:

<template>
  <h1>${router.title}</h1>
  
  <nav>
    <ul>
      <li repeat.for="nav of router.navigation">
        <a href.bind="nav.href">${nav.title}</a>
      </li>
    </ul>
  </nav>

  <router-view></router-view>
</template>

This template includes:

• A title that the router will set

• A navigation menu that will be automatically populated based on your route configuration

• A <router-view> element, which serves as a placeholder where route components will be rendered

Configure the Router

In src/app.ts, implement the configureRouter() method:

import { RouterConfiguration, Router } from 'aurelia-router';
import { PLATFORM } from 'aurelia-framework';

export class App {
  router: Router;

  configureRouter(config: RouterConfiguration, router: Router): void {
    this.router = router;
    config.title = 'My Aurelia App';
    config.map([
      { route: ['', 'home'], name: 'home', moduleId: PLATFORM.moduleName('home/index'), nav: true, title: 'Home' },
      { route: 'users', name: 'users', moduleId: PLATFORM.moduleName('users/index'), nav: true, title: 'Users' }
    ]);
  }
}

This configuration:

• Sets the base title for your application

• Defines two routes: a home route and a user route

• Uses PLATFORM.moduleName() for webpack compatibility

• Marks both routes as nav: true so they appear in the navigation menu

Create Route Components

For each route, create a corresponding component. For example:

In src/home/index.html:

<template>
  <h2>Welcome to the Home Page</h2>
</template>

In src/home/index.ts:

export class Home {
  // Component logic here
}

Create similar files for the Users route.

The Basics

• The <router-view> element in your app template is where route components will be rendered.

• The configureRouter() method is where you set up your routes and any router-specific configuration.

• Each route in the config.map() array defines a different "page" or view in your application.

• The moduleId specifies which component should be loaded for each route.

• Setting nav: true includes the route in the router.navigation array, which you can use to build navigation menus.

The <router-view> element is required when using the router.
