Angular integration

Start with the installation of Fluid Design System in the Angular framework

npm (tag) Fluid Licence

Installation

To consume Fluid Design System with Angular, the best way is via npm (or yarn if you prefer).

npm install @engie-group/fluid-design-system

Fonts and icons

The Fluid Design System uses the Lato font as global font family, read more about the typography bias on the dedicated section.

ENGIE has selected the Google material font as default icons pack, read more on the icons documentation.

Be sure to include these fonts into the main CSS file src/style.scss (or css, less, etc… according to your project configurations).

/* You can add global styles to this file, and also import other style files */
@import url('https://fonts.googleapis.com/css?family=Material+Icons|Lato:300,400,700,900&display=swap');

Stylesheets

In order to add stylesheets of the library in your project you have to include it in your angular.json file (which is at angular’s root directory).

"architect": {
    "build": {
        "options": {
            "styles": [
                "src/styles.scss",
                "node_modules/@engie-group/fluid-design-system/lib/fluid-design-system.css"
            ],
CSS version

Import the entire library

"node_modules/@engie-group/fluid-design-system/lib/fluid-design-system.css"

… or an single component

"node_modules/@engie-group/fluid-design-system/lib/components/form/index.css"
SCSS version

Import the full library

"node_modules/@engie-group/fluid-design-system/src/fluid-design-system.scss"

… or an single component

"node_modules/@engie-group/fluid-design-system/src/reboot.scss"
"node_modules/@engie-group/fluid-design-system/src/components/form/_index.scss"

JavaScript

NEW Automatic component initialization

Set an id attribute named root on a global container from where components will be watched for initialization.

  <app-root id="root"></app-root>

Import lib/fluid-design-system.js then lib/auto-init.js directly in your main app code.

import '@engie-group/fluid-design-system/lib/fluid-design-system';
import '@engie-group/fluid-design-system/lib/auto-init';

Don’t use custom tags unless you want to.

<nj-alert> <- remove custom tag
  <div class="nj-alert nj-alert--primary" role="alert">
   ...
  </div>

Initialization via WebComponents

1) Install additional modules

Required npm modules
Popper.js
web-animations-js
@webcomponents/webcomponentsjs
@webcomponents/custom-elements

If your application build es5 javascript, you need to include custom-elements-es5-adapter.js

import '@webcomponents/webcomponentsjs/custom-elements-es5-adapter.js';

If your application must be compatible with browser not supporting custom tag, you also have to install the @webcomponents/custom-elements polyfill:

import '@webcomponents/custom-elements/custom-elements.min.js';

2) Make sure that Angular includes the CUSTOM_ELEMENTS_SCHEMA schema:

// src/app/app.module.ts
...
import { NgModule, CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';
...
@NgModule({
  ...
  schemas: [CUSTOM_ELEMENTS_SCHEMA],
  ...
})

3) Initiate components

Import the library

// src/app/app.component.ts
import { Component, OnInit } from '@angular/core';
import { NJWC } from '@engie-group/fluid-design-system/lib-esm/fluid-design-system';

export class AppComponent implements OnInit {
  ngOnInit() {
    // Initialize every components
    NJWC.AutoInit();

    // Initialize a single component
    // NJWC.Form.init();
  }
}

Import a single component

// src/app/app.component.ts
import { Component, OnInit, ViewChild } from '@angular/core';
import { FormWC } from '@engie-group/fluid-design-system/lib-esm/components/form';

export class SpecificComponent implements OnInit {
  ngOnInit() {
    FormWC.init();
  }
}

Example

You could have a look at a todo list application example.
