Dependencies

The footer requires Angular Material, FlexLayout, FontAwesome and NgConnectionService.

These can all be integrated via the terminal:

Angular Material: ng add @angular/material FontAwesome: npm i -s @fortawesome/free-solid-svg-icons @fortawesome/[email protected] FlexLayout: npm i -s @angular/flex-layout @angular/cdk Connection Service: npm i -s ng-connection-service Installation

install the library via NPM:

npm i -s bb-itag-angular-footer shortcut with all dependencies together:

npm i -s @fortawesome/free-solid-svg-icons @fortawesome/[email protected] @angular/flex-layout @angular/cdk bb-itag-angular-footer ng-connection-service Using the library in the application

To use the library in your application, add add to the app.module ts the following import:

import { BbItagAngularFooterModule } from 'bb-itag-angular-footer'

// add the footer module in the module imports @NgModule({ imports: BbItagAngularFooterModule })

add the footer to your application. We recommend to create your own mainApp component but you can use it direct in the app-component files.

app.component.html

Footer Configuration

You can configure the footer so it allows you to only display the wanted elements.

First of all, we need to declare in the typescript file of our component which attributes we want wo use to configure the footer. In the example below are all of the possible attributes listed.

app.component.ts

// the application version which gets displayed at the bottom left (default: null) public appVersion: string = 'Version: 1.0'; // boolean if the cursor should be an pointer or an arrow. Needs to be true to use routerLink and click event (default: true) public showPointer: boolean = true; // the material color settings warn, accent or primary (default 'primary') of the footer when it's online public onlineThemePalette: ThemePalette = 'primary'; // the material color settings warn, accent or primary (default 'warn') of the footer when it's offline public offlineThemePalette: ThemePalette = 'warn'; // the font awesome icon that gets displayed when you're online (default: 'faNetworkWired') public onlineFaIconDefinition: any = faAddressBook; // the font awesome icon that gets displayed when you're offline (default: 'faExclamationTriangle') public offlineFaIconDefinition: any = faTable; // the text that gets displayed at the bottom right when you're online (default: 'ONLINE') public onlineText: string = 'connected'; // the text that gets displayed at the bottom right when you're offline (default: 'OFFLINE') public offlineText: string = 'disconnected'; // the router link on the version / text on the left. (default /) public versionRouterLink: string = null; // what global css class we have to use to show the active menu (default: 'defaultVersion' this is an internal class) public versionRouterLinkClass: string = 'footerActiveRouterLink'; Then we refer in app.component.html to the config settings. All parameters have a default value you only need to pass the attributes which you have declared in the typescript file.

app.component.html

<lib-bb-itag-angular-footer [appVersion]="appVersion" [showPointer]="showPointer" [onlineThemePalette]="onlineThemePalette" [offlineThemePalette]="offlineThemePalette" [onlineFaIconDefinition]="onlineFaIconDefinition" [offlineFaIconDefinition]="offlineFaIconDefinition" [onlineText]="onlineText" [offlineText]="offlineText" [versionRouterLink]="versionRouterLink" [versionRouterLinkClass]="versionRouterLinkClass" (appVersionClicked)="onFooterAppVersionClicked($event)" [online]="isOnline$ | async"> Now the footer should be displayed with the contents you've set and look like this:

footer with attributes set

explanation of the attributes

appVersion

Display the application version on the left side of the footer.

datatype

string default

null You can get the application version from the package.json if you want to like this:

// @ts-ignore import * as pjson from '../../package.json';

public appVersion: string = Version: ${pjson.version}; showPointer

When you hover over the application version you can decide if you want the cursor as pointer or as default. If it's false then you're no able to use features like routerLink and the version click event on the version label.

datatype

boolean default

true onlineThemePalette

The onlineThemePalette that you can choose between primary, accent, warn. This defines the color of the footer when it's online

datatype

import { ThemePalette } from '@angular/material/core'; default

'primary' offlineThemePalette

The offlineThemePalette that you can choose between primary, accent, warn. This defines the color of the footer when it's offline

datatype

import { ThemePalette } from '@angular/material/core'; default

'warn' onlineFaIconDefinition

With this attribute you can declare the font awesome icon that gets displayed when you're online. You just need to get the corresponding import from font awesome.

datatype

any default

faNetworkWired offlineFaIconDefinition

null versionRouterLinkClass

With versionRouterLinkClass you're able to set an css class, which is used when the routerLink is active.

Create a class in your theme.scss or styles.scss just so it is global. Example: .activeVersionRouterLink { color: green; } Set the class in your typescript file: activeVersionRouterLink datatype

string default

Internal css class

footerActiveRouterLink Version Click Event

The footer libary has a ready-made click event that you can use and create a function for it.

Add to the template an click event called appVersionClicked:

<lib-bb-itag-angular-footer (appVersionClicked)="onFooterClicked($event)">` Then create in the typescript file of the component a method:

Example:

onFooterClicked(appVersion: string) { // code alert(appVersion); } connection-service

The connection service allows you that the footer adapts to the corresponding connection state. Withe the following changes: isOnline is an observable which you can subscribe to easy via the async pipe. The default value for the footer is true.

Online: footer online

Offline: footer offline

component.html

<lib-bb-itag-angular-footer [online]="isOnline$ | async"> component.ts

public isOnline$: Observable;

constructor( connectionService: ConnectionService, ) { // this.isOnline$ = of(true); this.isOnline$ = connectionService.monitor(); } IFooterConfiguration

contains all possible settings for internal use only but you may can see all possible options here:

export interface IFooterConfiguration { // the application version which gets displayed at the bottom left (default: null) appVersion: string; // the material color settings warn, accent or primary (default 'primary') of the footer when it's online onlineThemePalette: ThemePalette; // the material color settings warn, accent or primary (default 'warn') of the footer when it's offline offlineThemePalette: ThemePalette; // the font awesome icon that gets displayed when you're online (default: 'faNetworkWired') onlineFaIconDefinition: any; // the font awesome icon that gets displayed when you're offline (default: 'faExclamationTriangle') offlineFaIconDefinition: any; // the text that gets displayed at the bottom right when you're online (default: 'ONLINE') onlineText: string; // the text that gets displayed at the bottom right when you're offline (default: 'OFFLINE') offlineText: string; // boolean if the cursor should be an pointer or an arrow. Needs to be true to use routerLink and click event (default: true) showPointer: boolean; // the router link on the version / text on the left. (default /) versionRouterLink: string; // what global css class we have to use to show the active menu (default: 'defaultVersion' this is an internal class) versionRouterLinkClass: string; }
