angular-typer v0.5.5

#Typer

Typer is an Angular directive that simulates someone typing and deleting over a list of words. The directive is highly customisable and allows the words to be set by passing an array of strings as an attribute, the transition times can be set on the directive aswell as callback functions to get invoked after each action ('Type', 'Delete', 'Highlight')

Documentation

Installation

include the typer directive source file in your html

 <script src="path/to/typer.js"></script>

Mark the typer module as a dependecy of your angular app

angular.module('myApp', ['typer']);

Alternative

install with npm

npm install angular-typer

Using a module bundler such as webpack or browserify require the typer module as a dependecy of your angular app

var angular = require('angular');

angular.module('app', [
	require('angular-typer')
]);

Then declare the typer directive in your markup

<typer words="['JavaScript', 'Angular', 'Cats']" type-time='150' backspace-time='200' start-delay='1500' highlight-background='#2980b9'></typer>

Note: The directive will inherit the styles of its parent element so it is recommmend to nest it like below

 <h1 class="main-title">I love <typer words="['JavaScript', 'Angular', 'Cats']" type-time='150' backspace-time='200' start-delay='1500' highlight-background='#2980b9'></typer></h1>
