Angular UI Switch Component

Description

This is a simple iOS 7 style switch component for Angular.

Inspired by switchery in Angular.

Installation

npm: npm install ngx-ui-switch --save

yarn: yarn add ngx-ui-switch

Some features are not available in previous versions:

• CSS styling
• Switch content (checkedLabel, uncheckedLabel) #309 #343
• Global options
• beforeChange event #314 #359

Usage

• Import into a module (AppModule example below)

// app.module.ts
import { UiSwitchModule } from 'ngx-ui-switch';
import { AppComponent } from './app.component';

@NgModule({
  imports: [BrowserModule, UiSwitchModule],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}

• Add default css file to appropriate project(s) angular.json

"styles": [
  "src/styles.css",
  "./node_modules/ngx-ui-switch/ui-switch.component.css"
]

Alternatively, the scss version can be imported into a scss file:

@import '~ngx-ui-switch/ui-switch.component.scss';

Global config

Use when you want to change default values globally.

These settings will override anything passed in via property bindings.

import { UiSwitchModule } from 'ngx-ui-switch';
import { AppComponent } from './app.component';

@NgModule({
  imports: [
    BrowserModule,
    UiSwitchModule.forRoot({
      size: 'small',
      color: 'rgb(0, 189, 99)',
      switchColor: '#80FFA2',
      defaultBgColor: '#00ACFF',
      defaultBoColor : '#476EFF',
      checkedLabel: 'on',
      uncheckedLabel: 'off'
    })
  ],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {}

<ui-switch></ui-switch>

Note that if you are using the switch in a child NgModule, such as a lazy loaded module, then you must also import the module in the module itself or within a shared module. Otherwise you will get the error that it is an unknown component as seen in issue #227.
