Capacitor updater

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.

iOS

Privacy manifest

Add the NSPrivacyAccessedAPICategoryUserDefaults dictionary key to your Privacy Manifest (usually ios/App/PrivacyInfo.xcprivacy):

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>NSPrivacyAccessedAPITypes</key>
    <array>
      <!-- Add this dict entry to the array if the file already exists. -->
      <dict>
        <key>NSPrivacyAccessedAPIType</key>
        <string>NSPrivacyAccessedAPICategoryUserDefaults</string>
        <key>NSPrivacyAccessedAPITypeReasons</key>
        <array>
          <string>CA92.1</string>
        </array>
      </dict>
    </array>
  </dict>
</plist>

We recommend to declare CA92.1 as the reason for accessing the UserDefaults API.

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.

For detailed instructions on the auto-update setup, refer to 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 Updater 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.

Store Guideline Compliance

Android Google Play and iOS App Store have corresponding guidelines that have rules you should be aware of before integrating the Capacitor-updater solution within your application.

Google play

Third paragraph of Device and Network Abuse topic describe that updating source code by any method besides Google Play's update mechanism is restricted. But this restriction does not apply to updating JavaScript bundles.

This restriction does not apply to code that runs in a virtual machine and has limited access to Android APIs (such as JavaScript in a web view or browser).

That fully allow Capacitor-updater as it updates just JS bundles and can't update native code part.

App Store

Paragraph 3.3.2, since back in 2015's Apple Developer Program License Agreement fully allowed performing over-the-air updates of JavaScript and assets.

And in its latest version (20170605) downloadable here this ruling is even broader:

Interpreted code may be downloaded to an Application, but only so long as such code:

• (a) does not change the primary purpose of the Application by providing features or functionality that are inconsistent with the intended and advertised purpose of the Application as submitted to the App Store
• (b) does not create a store or storefront for other code or applications
• (c) does not bypass signing, sandbox, or other security features of the OS.

Capacitor-updater allows you to respect these rules in full compliance, so long as the update you push does not significantly deviate your product from its original App Store approved intent.

To further remain in compliance with Apple's guidelines, we suggest that App Store-distributed apps don't enable the Force update scenario, since in the App Store Review Guidelines it is written that:

Apps must not force users to rate the app, review the app, download other apps, or other similar actions to access functionality, content, or use of the app.

This is not a problem for the default behavior of background update, since it won't force the user to apply the new version until the next app close, but at least you should be aware of that ruling if you decide to show it.

Packaging dist.zip update bundles

Capacitor Updater 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.

Listen to download events

  import { CapacitorUpdater } from '@capgo/capacitor-updater';

CapacitorUpdater.addListener('download', (info: any) => {
  console.log('download was fired', info.percent);
});

On iOS, Apple don't allow you to show a message when the app is updated, so you can't show a progress bar.
