aurelia-navigation-menu plugin

Enables eager loading of child routes and creates a navigation menu based on routes and child routes.

Installing

Install with npm npm install aurelia-navigation-menu --save

If you're using the CLI add the dependency

CLI

"dependencies": [
  // ...
  "aurelia-navigation-menu",
  //...
]

Usage

Eager Loading of Child Routers with a Truthy nav property.

By Default only routes that have nav set to true will be eager loaded

configureRouter(config: RouterConfiguration, router: Router) {
  config.options.eagerLoadAll = true;
  config.map([
    { route: ['', 'home'], name: 'home',  moduleId: 'routes/home/index',  nav: true, title: 'Home' },
    { route: 'cats',       name: 'cats',  moduleId: 'routes/cats/index',  nav: true, title: 'Cats' },
    { route: 'dogs',       name: 'dogs',  moduleId: 'routes/dogs/index',  nav: true, title: 'Dogs' },
    { route: 'birds',      name: 'birds', moduleId: 'routes/birds/index', title: 'Birds' }
  ]);
  this.router = router;
}

In the above example Home, Cats and Dogs will be checked for a router component.

If you have nested child routes then you need to add eagerLoadAll to each child configureRouter function.

Eager Load All Child Routers (even with a Falsy or undefined nav property)

configureRouter(config: RouterConfiguration, router: Router) {
  config.options.eagerLoadAll = true;
  config.options.eagerIgnoreNav = true;
  config.title = 'Child Route Menu Example';
  config.map([
    { route: ['', 'home'], name: 'home',  moduleId: 'routes/home/index', title: 'Home' },
    { route: 'cats',       name: 'cats',  moduleId: 'routes/cats/index', title: 'Cats' },
    { route: 'dogs',       name: 'dogs',  moduleId: 'routes/dogs/index', title: 'Dogs' },
    { route: 'birds',      name: 'birds', moduleId: 'routes/birds/index', nav: true, title: 'Birds' }
  ]);
  this.router = router;
}

Using The Navigation Menu

This plugin add's a navigation property each navigation item within the App Router. For example using the above code you can get Cat's routes by checking: router.navigation[1].navigation

Ensuring The Navigation Menu Is Loaded

** if you return ensureMenu from the activate method - the app will deadlock. **

import { NavigationMenu } from 'aurelia-navigation-menu';
import { inject } from 'aurelia-dependency-injection';

@inject(NavigationMenu)
export class App {
  constructor(navigationMenu) {
    this.navigationMenu = navigationMenu;
  }
  activate(params) {
    this.navigationMenu.ensureMenu()
  }
}

Accessing The Navigation Menu

You can also access the navigation menu from the NavigationMenu object/class. In the above example the navigation items will be under: navigationMenu.menu

Creating A Nestable Menu

  1. Create a Custom Element (nav-menu.html)
<template bindable="navigation">
  <ul>
    <li repeat.for="row of navigation">
      <a href.bind="row.href" class="${row.isActive ? 'active' : ''}">${row.title}</a>
      <nav-menu if.bind="row.navigation" navigation.bind="row.navigation"></nav-menu>
    </li>
  </ul>
</template>
  1. Require and refence it in your View (app.html from above example)
<require from="resources/elements/nav-menu.html"></require>
<nav-menu navigation.bind="router.navigation"></nav-menu>

Building The Code

To build the code, follow these steps.

  1. Ensure that NodeJS is installed. This provides the platform on which the build tooling runs.
  2. From the project folder, execute the following command:
npm install
  1. Ensure that Gulp is installed. If you need to install it, use the following command:
npm install -g gulp
  1. To build the code, you can now run:
gulp build
  1. You will find the compiled code in the dist folder, available in three module formats: AMD, CommonJS and ES6.

  2. See gulpfile.js for other tasks related to generating the docs and linting.

Running The Tests

To run the unit tests, first ensure that you have followed the steps above in order to install all dependencies and successfully build the library. Once you have done that, proceed with these additional steps:

  1. Ensure that the Karma CLI is installed. If you need to install it, use the following command:
npm install -g karma-cli
  1. Ensure that jspm is installed. If you need to install it, use the following commnand:
npm install -g jspm
  1. Install the client-side dependencies with jspm:
jspm install
  1. You can now run the tests with this command:
karma start
