Stencil & Capacitor

Build native mobile apps with web technology and Stencil


Install Capacitor.

Add Capacitor to your project and create a config for your app

npm install @capacitor/core @capacitor/cli
npx cap init [name] [id] --web-dir=www

Build the Web App.

The compiled web assets will be copied into each Capacitor native platform during the next step.

npm run build

Install the native platforms you want to target.


Capacitor's native projects exist in their own top-level folders and should be considered part of your app (check them into source control).

npm i @capacitor/ios @capacitor/android
npx cap add android
npx cap add ios

Adding calls to Native APIs

With Capacitor installed, adding calls to native device features is as straight forward as calling other JavaScript methods

import { Component, Host, State, h } from '@stencil/core';
import { Geolocation } from '@capacitor/geolocation';

  tag: 'geolocation-page',
  shadow: true,
export class  GeolocationPage() {

  @State() loc = null;

  async getCurrentPosition() {
    const loc = await Geolocation.getCurrentPosition();
    this.loc = loc;

  render() {
    return (
        <p>Your location is:</p>
        <p>Latitude: {this.loc?.coords.latitude}</p>
        <p>Longitude: {this.loc?.coords.longitude}</p>

        <button onClick={() => this.getCurrentPosition()}>
          Get Current Location
