Capgo - Instant updates for capacitor Discord Discord npm GitHub latest commit https://good-labs.github.io/greater-good-affirmation/assets/images/badge.svg Security Rating Bugs Maintainability Rating Code Smells Vulnerabilities Quality Gate Status Technical Debt Open Bounties Rewarded Bounties

Update Ionic Capacitor apps without App/Play Store review (Code-push / hot-code updates).

You have 3 ways possible :

  • Use capgo.app a full featured auto update system in 5 min Setup, to manage version, update, revert and see stats.
  • Use your own server update with auto update system
  • Use manual methods to zip, upload, download, from JS to do it when you want.

Documentation

I maintain a more user friendly and complete documentation here.

Installation

npm install @capgo/capacitor-updater
npx cap sync

Auto-update setup

Create your account in capgo.app and get your API key

  • Login to CLI npx @capgo/cli@latest init API_KEY And follow the steps by step to setup your app.

See more there in the Auto update documentation.

Manual setup

Download update distribution zipfiles from a custom url. Manually control the entire update process.

  • Edit your capacitor.config.json like below, set autoUpdate to false.
// capacitor.config.json
{
	"appId": "**.***.**",
	"appName": "Name",
	"plugins": {
		"CapacitorUpdater": {
			"autoUpdate": false,
		}
	}
}
  • Add to your main code
  import { CapacitorUpdater } from '@capgo/capacitor-updater'
  CapacitorUpdater.notifyAppReady()

This informs Capacitor Updator that the current update bundle has loaded succesfully. Failing to call this method will cause your application to be rolled back to the previously successful version (or built-in bundle).

  • Add this to your application.
  const version = await CapacitorUpdater.download({
    url: 'https://github.com/Cap-go/demo-app/releases/download/0.0.4/dist.zip',
  })
  await CapacitorUpdater.set(version); // sets the new version, and reloads the app
  • Failed updates will automatically roll back to the last successful version.
  • Example: Using App-state to control updates, with SplashScreen: You might also consider performing auto-update when application state changes, and using the Splash Screen to improve user experience.
  import { CapacitorUpdater, VersionInfo } from '@capgo/capacitor-updater'
  import { SplashScreen } from '@capacitor/splash-screen'
  import { App } from '@capacitor/app'

  let version: VersionInfo;
  App.addListener('appStateChange', async (state) => {
      if (state.isActive) {
        // Ensure download occurs while the app is active, or download may fail
        version = await CapacitorUpdater.download({
          url: 'https://github.com/Cap-go/demo-app/releases/download/0.0.4/dist.zip',
        })
      }

      if (!state.isActive && version) {
        // Activate the update when the application is sent to background
        SplashScreen.show()
        try {
          await CapacitorUpdater.set(version);
          // At this point, the new version should be active, and will need to hide the splash screen
        } catch () {
          SplashScreen.hide() // Hide the splash screen again if something went wrong
        }
      }
  })

TIP: If you prefer a secure and automated way to update your app, you can use capgo.app - a full-featured, auto update system.

Packaging dist.zip update bundles

Capacitor Updator works by unzipping a compiled app bundle to the native device filesystem. Whatever you choose to name the file you upload/download from your release/update server URL (via either manual or automatic updating), this .zip bundle must meet the following requirements:

  • The zip file should contain the full contents of your production Capacitor build output folder, usually {project directory}/dist/ or {project directory}/www/. This is where index.html will be located, and it should also contain all bundled JavaScript, CSS, and web resources necessary for your app to run.
  • Do not password encrypt the bundle zip file, or it will fail to unpack.
  • Make sure the bundle does not contain any extra hidden files or folders, or it may fail to unpack.
