Highlight Features

• Generate digital proofs on media assets created.
• WIP: Publish digital proofs to decentralized networks.

Demo App

The demo app is hosted on GitHub Page. You can simulate the mobile device by toggling device mode with Chrome DevTools.

Getting Started

Node.js 10.16.0+ is required.

Install the dependencies.

npm i

Preview the app in web browser.

ionic serve

Verification

The signature of proofs can be verified with Web Crypto API. The signed message is generated by services/serialization/serialization.service.ts#stringify() method. A Python example for verification can be found in the Starling Capture repository.

Development

Start a local dev server for app dev/testing.

ionic serve

Run tests.

npm run test

Run tests in headless mode.

npm run test-ci

Lint the projects.

npm run lint

Update cordova-res (splash screens and launcher icons).

cordova-res android --skip-config --copy

Contribution

• The committed codes should pass all GitHub workflows.
• Avoid using getters/setters in TypeScript so the linter for RxJS can correctly identify the unsafe scope.

Platform

Android

If your operating system is Linux, set the linuxAndroidStudioPath in capacitor.config.json. For example,

{
  "linuxAndroidStudioPath": "/home/username/android-studio/bin/studio.sh"
}

Before running the app with Android Studio, build and sync the dependencies and web assets.

ionic build
npx cap sync

Open the project in Android Studio.

npx cap open android

The script does the same thing for you.

npm run build-android

Architecture

See the architecture of Starling Capture for details.

Serialization Schema

See the serialization schema of Starling Capture for details.

Caveat

• This app is still in the experimental stage.
• This app uses raw file system to save proofs, and thus the performance is not optimized.

Release

Bump version in package.json.

{
  "version": "a.b.c"
}

Bump version in android/app/build.gradle.

android {
    defaultConfig {
        versionCode abc
        versionName "a.b.c"
    }
}

When push to the develop branch with new version in the package.json file, GitHub Action would automatically create new release.

Deploy

Demo App

The demo app is hosted on the GitHub Page. It would be updated when there is a new commit on the master branch.
