ngx-walkthrough
Update of https://github.com/souly1/ng-walkthrough for angular > 5
One of the most common design challenges emerging in mobile design is that of 'invitation' - creating an explanation walk through during user first interaction with the app so to engage him. Following Theresa Neil's design patterns from [Mobile Design Pattern Gallery] (http://www.amazon.com/gp/product/1449314325/ref=as_li_ss_tl?ie=UTF8&tag=uxbo09-20&linkCode=as2&camp=217145&creative=399373&creativeASIN=1449314325)
This angular component implements a walkthrough via one of the following patterns: the transparency pattern or the tip pattern (an explanation about the different patterns can be found online at ux booth)
Get the Changelog.
Special features
- Use the transparency walkthrough either using transclude or given attributes which contain basics such as text, gesture image, 'got it' button
- In transparency walkthrough easily highlight a DOM element (see demo)
- Use any image you want or choose a gesture image from the given collection (such as swipe with direction or tap) and place it bound to the element mentioned above.
- automatically moves text to bottom if item is covering the text with icon or arrow
- In tip mode add an Icon to sit on top or behind the tip text box
ScreenShots
Transparency walkthrough in Classic, Classic with arrow mode and Totally customizable mode respectively (these screenshots have been realized on the previous version of the library, the design can be slightly different now):
Tip walkthrough mode:
Demo
A demo of the previous version was created to show (Note: that the attributes have been changed, see example bellow):
- The 2 basic transparency overlay types in 3 demoes fitting the screenshot examples - one basic template, one with arrows, and the last freestyle one using transclude.
- The tip mode walkthrough Demo can be found here
Requirements
- Angular 5 or superior
Installation
- NPM:
npm install ngx-walkthrough
- Bower:
bower install ngx-walkthrough
Usage
Import the module in your appplication module
import { WalkthroughModule } from 'ngx-walkthrough';
then declare it in your app imports:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { WalkthroughModule } from 'ngx-walkthrough';
@NgModule({
imports: [
BrowserModule,
WalkthroughModule
],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule {}
You can now use the component, add the element to your HTML:
<walkthrough [walkthrough-type]="'X'">
...
</walkthrough>
and use one of the two configurations: 1> Place any HTML code as you like instead of the three dotes as this uses the Angular transclude ability. Make sure to specify [walkthrough-type]="transparency" or "tip" for this to work. 2> Use the additional optional properties the component has to quickly create a walkthrough screen.
Usage Example 1 - transparency Non transclude option
<walkthrough
[is-round]="true"
[walkthrough-type]="'transparency'"
[focus-element-selector]="'#focusItem'"
[icon]="'single_tap'"
[main-caption]="'This is some text'"
[is-active]="true"
[use-button]="true">
</walkthrough>
Usage Example 2 - transparency using transclude option
<walkthrough [is-active]="true" [walkthrough-type]="'transparency'">
<img src="images/ImageTutorialExample.png" style="height: 100vh; width: 100%;">
</walkthrough>
Usage Example 3 - tip type walkthrough
<walkthrough
[walkthrough-type]="'tip'"
[icon]="'images/myLogo.png'"
[tip-icon-location]="'FRONT'"
[tip-location]="'TOP'"
[main-caption]="'This is some text'"
[tip-color]="'BLACK'"
[is-active]="true"
[use-button]="true">
</walkthrough>
Usage Example 4 - transparency Non transclude option full code with output
import { Component } from '@angular/core';
import { AngularFirestore } from 'angularfire2/firestore';
import { Observable } from 'rxjs/Observable';
@Component({
selector: 'app-root',
template: `

(on-walkthrough-show)="myShowFunction()"
(on-walkthrough-hide)="myHideFunction()">
</walkthrough>
`
})
export class MyApp {
constructor() {
}
myShowFunction(){
