Documentation

Introduction

This Angular library provides a basic scaffold for modern web and mobile applications and includes ui elements such as header, sidebar, drawer, footer, floating button etc as well as basic services to display snackbars, dialogs and more. Simply wrap your router-outlet with the lf-scaffold element and start configuring the ScaffoldConfig in the ScaffoldService store.

Installation

Install the npm package npm install @lukfel/scaffold.

Module

Import the module ScaffoldModule in your app.module.ts.

Hint: The library has a built in logger service Logger which logs certain events if a LibraryConfig is passed and the property production is to false (no logging in production mode).

import { ScaffoldModule } from '@lukfel/scaffold';
import { environment as env } from 'src/environments/environment';

imports: [
  ...
  // omit '.forRoot( { production: env.production } )' if you don't need the logger
  ScaffoldModule.forRoot( { production: env.production } )
],

Style

Import the styles @lukfel/scaffold/styles on top of your styles.scss and include the theme.

Hint: The styles also include material icons and the roboto font.

@use "@lukfel/scaffold/styles" as lf;
@include lf.scaffold-theme();     // include the default theme
...

Custom Theme

To customize the theme, overwrite the color palettes directly after the @use "@lukfel/scaffold/styles" as lf import.

Hint: To use Material palettes, install and import the Angular Material library in your application.

@use "@lukfel/scaffold/styles" as lf;
@use '@angular/material' as mat;

$theme: (
  primary: mat.define-palette(mat.$pink-palette),
  accent: mat.define-palette(mat.$blue-palette),
  warn: mat.define-palette(mat.$red-palette),
  dark: false
);

@include lf.scaffold-theme($theme);
...

Multiple Themes

To dynamically switch between themes, create and include the theme with lf.scaffold-colors($theme2, 'theme2') where the second parameter is the class name that needs to be present on the body like <body class="theme2">.

Hint: You can dynamically change to an available theme with the service ThemeService.

@use "@lukfel/scaffold/styles" as lf;
@use '@angular/material' as mat;

$base-theme: (
  primary: mat.define-palette(mat.$pink-palette),
  accent: mat.define-palette(mat.$blue-palette),
  warn: mat.define-palette(mat.$red-palette),
  dark: false
);

$theme2: (
  primary: mat.define-palette(mat.$purple-palette),
  accent: mat.define-palette(mat.$amber-palette),
  dark: false
);

@include lf.scaffold-theme($base-theme);              // Set the primary theme with lf.scaffold-theme(...)
@include lf.scaffold-colors($theme2, 'theme2');       // Set additional themes with lf.scaffold-colors(...)
...

Custom Typography

The change the default typography from Roboto, you can pass an additional property font-family in the base theme map.

Hint: Don't forget to import and set your desired font-family in your application.

@use "@lukfel/scaffold/styles" as lf;
@use '@angular/material' as mat;

$base-theme: (
  primary: mat.define-palette(mat.$pink-palette),
  accent: mat.define-palette(mat.$blue-palette),
  warn: mat.define-palette(mat.$red-palette),
  dark: false,
  font-family: 'Comic Sans'
);

@include lf.scaffold-theme($base-theme); 

body {
    font-family: "Comic Sans MS" !important;
}
...

Template

Add the lf-scaffold element to your app.component.html.

<lf-scaffold>
  <router-outlet></router-outlet>
</lf-scaffold>

Config

Import the ScaffoldService in your app.component.ts.

Hint: The ScaffoldService is the global store of the library. With this service you can change the ScaffoldConfig and subscribe to the Observable to detect changes.

import { ScaffoldService } from '@lukfel/scaffold';

export class AppComponent {

  constructor(private scaffoldService: ScaffoldService) {}

}

Create the ScaffoldConfig object in your app.component.ts and set it in the ScaffoldService.

Hint: If a sub config (e.g. headerConfig) is not defined within the ScaffoldConfig or doesn't have the property enable: true, the corresponding ui element won't be displayed.

import { ScaffoldService, ScaffoldConfig } from '@lukfel/scaffold';

export class AppComponent {

  public scaffoldConfig: ScaffoldConfig = {
    scrollPositionRestoration: true,
    // see HeaderConfig
    headerConfig: {
      enable: true,
      title: 'Scaffold',
      subtitle: 'by Lukas Felbinger',
      leftMenuButton: {
        id: 'menu',
        matIcon: 'menu'
      },
      rightMenuButtons: [
        {
          id: 'item1',
          label: 'Item 1'
        },
        {
          id: 'item2',
          label: 'Item 2'
        },
        {
          id: 'item3',
          matIcon: 'settings'
        }
      ],
      inputConfig: {
        enable: false
      }
    },
    // see NavbarConfig
    navbarConfig: {
      enable: true,
      showAllLabels: true,
      menuButtons: [
        {
          id: 'nav1',
          label: 'Nav 1',
          matIcon: 'looks_one'
        },
        {
          id: 'nav2',
          label: 'Nav 2',
          matIcon: 'looks_two'
        },
        {
          id: 'nav3',
          label: 'Nav 3',
          matIcon: 'looks_3'
        }
      ]
    },
    // see DrawerConfig
    drawerConfig: {
      enable: false
    },
    // see FooterConfig
    footerConfig: {
      enable: true,
      links: [
        {
          label: 'Link 1'
        },
        {
          label: 'Link 2'
        },
      ],

    },
    // see ContentTitleCardConfig
    contentTitleCardConfig: {
      enable: true,
      label: 'Example Title',
      showBackButton: true
    },
    // see FloatingButtonConfig
    floatingButtonConfig: {
      enable: true
    }
  }

  constructor(private scaffoldService: ScaffoldService) {
    // Set the new scaffoldConfig in the global store
    this.scaffoldService.scaffoldConfig = this.scaffoldConfig;
  }

}

Events

To listen to scaffold user events, add the output events and define the corresponding methods in your app.component.ts.

<lf-scaffold
  (headerButtonClickEvent)="headerButtonClickEvent($event)"
  (headerInputSubmitEvent)="headerInputSubmitEvent($event)"
  (headerInputChangeEvent)="headerInputChangeEvent($event)"
  (navbarButtonClickEvent)="navbarButtonClickEvent($event)">
  <!-- drawer content (content that is placed in the left drawer if enabled) -->
  <ng-container drawerContent></ng-container>
  <!-- main content -->
  <router-outlet></router-outlet>
</lf-scaffold>

// Listen to header click events (header menu buttons - click)
public headerButtonClickEvent(id: string): void {
  ...
}

// Listen to header input submit events (header input field - submit)
public headerInputSubmitEvent(value: string): void {
  ...
}

// Listen to header input change events (header input field - change)
public headerInputChangeEvent(value: string): void {
  ...
}

// Listen to navbar click events (navbar menu buttons - click)
public navbarButtonClickEvent(id: string): void {
  ...
}

Additional Services

The library provides some additional commonly used services, such as:

Logger (for logging during development only)
SnackbarService (display simple snackbars)
DialogService (display simple and custom dialogs)
BreakpointService (listen for breakpoint changes)
RouterService (listen for route changes and retrieve route history)
SeoService (set all meta tags with one method)
ThemeService (dynamically change the theme)

Logger

This service only logs out information if you set ScaffoldModule.forRoot( { production: env.production } ) where the production property must be false (no console logging in production mode).

import { Logger } from '@lukfel/scaffold';

export class AppComponent {

  constructor(private logger: Logger) {}
  
  // Generic api call with logging
  public apiCallWithLogging(): void {
    this.apiService.apiCall().then(result => {
      this.logger.log(result);
    }).catch(error => {
      this.logger.error(error);
    });
  }
}

SnackbarService

This service provides basic methods to display a simple snackbar with or without an action.

import { SnackbarService } from '@lukfel/scaffold';

export class AppComponent {

  constructor(private snackbarService: SnackbarService) {}
  
  // Generic api call with snackbar response
  public apiCallWithSnackbarResponse(): void {
    this.apiService.apiCall().then(result => {
      this.snackbarService.openSnackbar('Call was successful');
    }).catch(error => {
      this.snackbarService.openSnackbar('Call was not successful');
    });
  }
}

DialogService

This service provide a basic confirmation dialog with a boolean response. Additionally you can use the method openCustomDialog to pass your own dialog template and config.

import { DialogService } from '@lukfel/scaffold';

export class AppComponent {

  constructor(private dialogService: DialogService) {}
  
  // Generic api call with a subsequent confirmation dialog
  public apiCallWithDialogConfirmation(): void {
    this.dialogService.openConfirmDialog('Do you really want to make this api call?').then(response => {
      // If the user confirmed the dialog, go through with the api call
      if(response === true) {
        this.apiService.apiCall().then(result => {
          ...
        }).catch(error => {
          ...
        }); 
      }
    });
  }
}

BreakpointService

This service allows you to subscribe to breakpoint changes and act accordingly

import { BreakpointService } from '@lukfel/scaffold';

export class AppComponent {

  constructor(private breakpointService: BreakpointService) {
    this.breakpointService.breakpoint$.subscribe((result: BreakpointState) => {
      // Check which breakpoint is active
      if (result.breakpoints[Breakpoints.XSmall]) {
        ...
      } else if (result.breakpoints[Breakpoints.Small]) {
        ...
      } else if (result.breakpoints[Breakpoints.Medium]) {
        ...
      } else if (result.breakpoints[Breakpoints.Large]) {
        ...
      }
    });
  }
}
