ngx-typed-js

An Angular integration for Typed.js.

Typed.js is a library that types. Enter in any string, and watch it type at the speed you've set, backspace what it's typed, and begin a new sentence for however many strings you've set.

NPM

Installation

npm install --save ngx-typed-js

Import in your module

import {NgxTypedJsModule} from 'ngx-typed-js';

@NgModule({
  imports: [
    NgxTypedJsModule,
  ],
})
export class AppModule {
}

Usage

To start using it add the ngx-typed-js component to your template and pass the text, which should be typed to the strings input. In addition you need to pass an element with the class typing to the component tag.

<ngx-typed-js [strings]="['Bananas are awesome', 'Nobody can argue this fact.']">
  <h1 class="typing"></h1>
</ngx-typed-js>

The typing class also allows you to just animate certain parts of a string:

<ngx-typed-js [strings]="['amazing.', 'yellow.', 'delicious.']" [shuffle]="true" [typeSpeed]="40">
  Bananas are <span class="typing"></span>
</ngx-typed-js>

Accessing methods exposed by vanilla Typed.js

You can access the methods on your Typed object by using a @ViewChild decorator:

  @ViewChild(NgxTypedJsComponent) typed: NgxTypedJsComponent;

Properties

You can make use of the following properties in order to customize your typing experience:

Property Type Description Usage
strings Array strings to be typed [strings]="['Text 1', 'Text 2']"
stringsElement String ID of element containing string children [stringsElement]="'myId'"
typeSpeed Number type speed in milliseconds [typeSpeed]="50"
startDelay Number time before typing starts in milliseconds [startDelay]="1000"
backSpeed Number backspacing speed in milliseconds [backSpeed]="10"
smartBackspace Boolean only backspace what doesn't match the previous string [smartBackspace]="true"
shuffle Boolean shuffle the strings [shuffle]="true"
backDelay Number time before backspacing in milliseconds [backDelay]="100"
fadeOut Boolean Fade out instead of backspace [fadeOut]="true"
fadeOutClass String css class for fade animation [fadeOutClass]="'fadeOutClass'"
fadeOutDelay Boolean fade out delay in milliseconds [fadeOutDelay]="true"
loop Boolean loop strings [loop]="true"
loopCount Number amount of loops [loopCount]="3"
showCursor Boolean show cursor [showCursor]="true"
cursorChar String character for cursor [cursorChar]="'_'"
autoInsertCss Boolean insert CSS for cursor and fadeOut into HTML [autoInsertCss]="true"
attr String attribute for typing Ex: input placeholder, value, or just HTML text [attr]="'placeholder'"
bindInputFocusEvents Boolean bind to focus and blur if el is text input [bindInputFocusEvents]="true"
contentType String 'html' or 'null' for plaintext [contentType]="'html'"

These are the same properties used with vanilla Typed.js. For more information about them check out the original project. In addition to the original properties I have added a new one: cursorColor. This takes the value of a CSS color string (e.g. [color]="red", [color]="#fff"). By default, the cursor color and size will be set to the values of computed styles of the passed .typing element.

Events

You can listen to the following events:

Event Description Usage
completed All typing is complete (completed)="doSmth()"
preStringTyped Before each string is typed (preStringTyped)="doSmth(indexOfString)"
stringTyped After each string is typed (stringTyped)="doSmth(indexOfString)"
lastStringBackspaced During looping, after last string is typed (lastStringBackspaced)="doSmth()"
typingPaused Typing has been stopped (typingPaused)="doSmth(indexOfString)"
typingResumed Typing has been started after being stopped (typingResumed)="doSmth(indexOfString)"
reset After reset (reset)="doSmth()"
stopped After stop (stopped)="doSmth(indexOfString)"
started After start (started)="doSmth(indexOfString)"
destroyed After destroy (destroyed)="doSmth()"

Examples

<!-- infinite loop -->
<ngx-typed-js [strings]="['awesome', 'amazing']" [loop]="true" (completed)="doSmth()">
  <h2>We are an <span class="typing"></span> company!</h2>
</ngx-typed-js>

<!-- type pausing -->
<ngx-typed-js [strings]="['This is text ^1000 which gets paused for 1 second']">
  <h2 class="typing"></h2>
</ngx-typed-js>

Thank you

Big thanks to the author of vue-typed-js from which I inspired heavily and of course to the original author of Typed.js.
