Hybrid Apps

What I do

• Build hybrid mobile applications using web technologies (HTML, CSS, JavaScript)
• Develop with frameworks like Ionic, Cordova, and Capacitor
• Create Progressive Web Apps (PWAs) with service workers
• Wrap web apps in native containers for app store deployment
• Access native device APIs through plugins
• Implement responsive designs for multiple screen sizes
• Manage hybrid app build pipelines

When to use me

Use me when:

• Building apps with web development skills
• Porting existing web apps to mobile
• Quick cross-platform deployment needed
• Budget constraints limit native development
• Simple utility or content-focused apps
• Need rapid iteration and deployment

Key Concepts

Hybrid Architecture

Hybrid apps run in a WebView but can access native APIs through bridges. They combine web and native components.

Ionic Framework

Popular hybrid framework using Angular, React, or Vue:

import { Component, OnInit } from '@angular/core';
import { Camera, CameraOptions } from '@ionic-native/camera/ngx';

@Component({
  selector: 'app-camera',
  template: `
    <ion-button (click)="takePicture()">Take Photo</ion-button>
    <ion-img [src]="imageUrl"></ion-img>
  `
})
export class CameraPage implements OnInit {
  imageUrl: string;

  constructor(private camera: Camera) {}

  takePicture() {
    const options: CameraOptions = {
      quality: 100,
      destinationType: this.camera.DestinationType.DATA_URL,
      encodingType: this.camera.EncodingType.JPEG
    };

    this.camera.getPicture(options).then(
      (imageData) => {
        this.imageUrl = 'data:image/jpeg;base64,' + imageData;
      }
    );
  }
}

Capacitor vs Cordova

• Capacitor: Modern successor, better native performance, simpler plugin system
• Cordova: Larger plugin ecosystem, mature but legacy

PWA Features

• Service workers for offline support
• Web App Manifest for installability
• Push notifications
• Background sync
