Use a third-party SDK

linked.lucent.ts

import { PLATFORM } from "lucent:platform";
import { RCTAppDependencyProvider } from "lucent:ios/ReactAppDependencyProvider";
import { ContextCompat } from "lucent:android/androidx.core.content";
import { PackageManager } from "lucent:android/android.content.pm";
import { appContext } from "lucent:android";

export async function linkedLibraries(): Promise<string> {
  if (PLATFORM === "ios") {
    const provider = new RCTAppDependencyProvider();
    return `${provider.urlRequestHandlerClassNames().length} request handlers, ${provider.imageDataDecoderClassNames().length} image decoders`;
  } else {
    const internet = ContextCompat.checkSelfPermission(appContext(), "android.permission.INTERNET");
    return `INTERNET granted ${internet === PackageManager.PERMISSION_GRANTED}`;
  }
}

A library the app already links is imported like the SDK: a pod's module on iOS, an AndroidX package on Android. This module is from the example apps, which add nothing for it.

Add a library

1. Add it to the app as usual: a pod in ios/Podfile, or a dependency in android/app/build.gradle.
2. iOS: run pod install. Lucent reads the pods' headers from the app's Pods folder.
3. Android: nothing more. lucent build asks Gradle for the app's compile classpath, and caches the answer until the Gradle files change.
4. Import from lucent:ios/<Module> or lucent:android/<package>.

• Swift Package Manager libraries can't be imported yet; CocoaPods ones can (roadmap).
• A library in a Lucent package goes in its lucent.json instead, so apps get it when they install the package.
