Angular Icon Inputs

This module contains a couple of Angular Input box components that allow to add an icon inside a text input, which helps better identify common input fields like for example email, etc.

This small module contains only the HTML and CSS necessary to implement this very common HTML pattern.

The default theme of the input is designed to look just like a plain HTML input, including the focus blue border (tab and shift-tab are supported).

Any icon available on either the Font Awesome or the Google Material Design Icon libraries can be used.

Features:

• The components have minimum styling and are themable
• there is no need to include a component-specific external stylesheet, only the Font Awesome or Material icons stylesheets
• As the input component takes a plain input and projects it, this means that by design the component supports all standard HTML input attributes, including custom attributes (data-), all the accessiblity properties, etc.
• This also means that these components are Compatible with Angular Forms
• This repo is based on the angular-quickstart-lib,
  which is a seed repo (under development) for a library in the Angular Package Format v4.0.
• This means for example that this module is compatible with AOT, and includes UMD bundles for use with SystemJs

Demo

Here is what the inputs with the icons look like on screen:

Installation

This is how to install the components:

npm install au-input

or

yarn add au-input

And on your application module:

import {AuInputModule} from 'au-input';

@NgModule({
  declarations: [ ...],
  imports: [
    BrowserModule,
    ....,
     AuInputModule
],
})
export class AppModule { }

See below for SystemJs / UMD installation.

Using the Font Awesome Inputs

We will need to add first a version of Font Awesome to our page, for example:

<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet">

Then we can use the Font Awesome Input like this:

<au-fa-input icon="envelope">
    <input auInput type="email" name="email" placeholder="Email" autocomplete="off" 
        class="some-class" data-stripe="email">
</au-fa-input>

<au-fa-input id="password-field" icon="lock" >
    <input auInput placeholder="Password" class="test-class">
</au-fa-input>

<au-fa-input  icon="cc-stripe">
    <input auInput placeholder="Stripe">
</au-fa-input>

<au-fa-input icon="paypal">
    <input auInput placeholder="Paypal">
</au-fa-input>

The inputs receive an input property named icon that identifies which Font Awesome icon we want to apply.

The value envelope will add the email icon by adding the CSS class fa-envelope to the icon, etc.

The input that you pass inside the component is just a plain HTML input that will be projected inside the component, so all the standard HTML properties of an input apply.

To make sure that the focus functionality is working correctly, make sure to apply the attribute directive auInput like in the examples.

Using the Material Design Input

We will need to add first a version of the Google Material Design icons to our page, for example:

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

Then we can use the Material Design Input like this:

<au-md-input icon="search">
    <input auInput type="email" name="email" placeholder="E-mail">
</au-md-input>

<au-md-input icon="perm_identity">
    <input auInput name="identity" placeholder="Identity Number">
</au-md-input>

<au-md-input icon="receipt">
    <input auInput name="receipt" placeholder="Receipt">
</au-md-input>

Running the Demo Application

This command will build and start the demo application:

npm start

Running This Module In Development

First let’s build the library using this command:

npm run build

Then let’s link it:

cd dist
npm link

On another folder on the same machine where we have for example a running Angular CLI, we then do:

npm link au-input

Running the Tests

The tests can be executed with the following commands:

npm test
npm integration

Using SystemJs via the UMD bundle ?

Make sure to add this to your map configuration, if you need the module served from a CDN:

map: {

   ...
   'au-input': 'https://unpkg.com/au-input@<version number>/au-input.umd.min.js'
}

Otherwise if serving from node_modulesdirectly:

map: {
   ...
   'au-input': 'node_modules/au-input/bundles/au-input.umd.min.js'
}

And in our packages property:

packages: {
   ...
  'au-input': {
    main: 'index.js',
    defaultExtension: 'js'
  }

}
