• Converts the application to Pods
• Converts the application to use Sass
• Adds routes /release-notes and 404 Not Found
• Modifies config/environment.js
• Modifies ember-cli-build.js
• Installs ember-cli-mirage and ember-cli-sass
• Uninstalls ember-welcome-page
• Adds public/.htaccess file
• Adds app/styles/_nrg-override.scss for theming

Example App

Ember NRG UI comes with a dummy app that implements all of the components. Check out that dummy app for reference. To start it, run

git clone git@github.com:knoxville-utilities-board/ember-nrg-ui.git
cd ember-nrg-ui
yarn install && ember serve

and go to http://localhost:4200.

Installation

Installing the library is as easy as:

ember install ember-nrg-ui

Getting Started

Hello World

Once the addon is installed, create a new index route and template:

// app/index/route.js

import Route from "@ember/routing/route";
import SidebarNavigationMixin from "ember-nrg-ui/mixins/sidebar-navigation";

export default Route.extend(SidebarNavigationMixin, {
  sidebarLabel: "Home"
});

<!-- app/index/template.hbs -->

<div class="ui segment basic">
  {{#nrg-home-cards as |view|}}
    {{view.home-card label="Hello World" icon="globe" route="index" meta="obligatory" }}
  {{/nrg-home-cards}}
</div>

Context Menu

Use the ContextMenuMixin to route the user to Release Notes by creating an application route.

// app/application/route.js

import Route from "@ember/routing/route";
import ContextMenuMixin from "ember-nrg-ui/mixins/context-menu";

export default Route.extend(ContextMenuMixin, {
  contextItems: [
    {
      label: "Release Notes",
      actionName: "routeToReleaseNotes",
      priority: 2
    }
  ],

  actions: {
    routeToReleaseNotes() {
      this.transitionTo("release-notes");
    }
  }
});

Theming

Use the _nrg-override.scss file to override base colors and Logo

// app/styles/_nrg-override.scss

$primary: #6200ee;
$primaryVariant: #3700b3;

.nrg-application.nrg-application.nrg-application > .main.menu {
  background-color: rgba($primary, 0.98);
}

.nrg-list.nrg-list.nrg-list .items > .item.active.active {
  background-color: $primary;
  & .description,
  & .description > a,
  & .header,
  & .meta,
  & > .icon {
    color: #fff;
  }
}

.home-card.home-card.home-card.home-card .image.icon {
  background-color: $primaryVariant;
}

Import the override file into the main app.scss

// app/styles/app.scss

@import "nrg-override";
