Install Ionic CLI ``` $ npm install -g ionic ``` Install dependencies ``` $ cd $ npm install ``` Run the app on a real device or simulator (to see how Touch ID/ Face ID works) ``` $ ionic cordova emulate ios ``` Or, just want to see the keypad UI: ``` $ ionic serve ``` See more at [Get started with Ionic](https://ionicframework.com/getting-started/) ## Lockscreen Module In this module: - Component: KeypadPage - Service: LockscreenService - sass/modal.scss (for fullscreen modal): needs to be included in global.scss Dependencies: - TapticEngine (https://ionicframework.com/docs/native/taptic-engine) - FingerprintAIO (https://ionicframework.com/docs/native/fingerprint-aio) ### Usage Include LockscreenModule in src/app/app.module.ts ``` import { LockscreenModule } from './plugins/lockscreen/lockscreen.module'; ... @NgModule({ imports: [ BrowserModule, IonicModule.forRoot(), AppRoutingModule, LockscreenModule, ], ``` Include LockscreenService in src/app/home/home.page.ts ``` import { LockscreenService } from '../plugins/lockscreen/services/lockscreen.service'; ... showLockscreen() { const options = { passcode: CORRECT_PASSCODE, enableTouchIdFaceId: this.enableTouchIdFaceId, }; this.lockscreenService.verify(options) .then((response: any) => { const { data } = response; console.info('Response from lockscreen service: ', data); if (data.type === 'dismiss') { this.isCorrect = data.data; } else { this.isCorrect = false; } }) } ```
