kmep

Dart package for the KMEP YouTube extraction library. See the repository README for the full pitch, feature matrix, and platform integration guide — this file is just the pub package quick-reference.

Quick start

import 'package:kmep/kmep.dart';

final kmep = Kmep.withOnDevicePoToken(
  jsRuntime: myPlayerJsRuntime,   // see ../flutter_integration or NodeProcessJsRuntime
  potJsRuntime: myBotGuardRuntime,
  fetchText: (url) => http.get(Uri.parse(url)).then((r) => r.body),
);

final video = await kmep.getVideo('dQw4w9WgXcQ');
final results = await kmep.search('lofi hip hop');

Runnable version: example/example.dart.

dart pub get
dart analyze
dart test

Diagnostic tools that hit live YouTube (not part of the public API, useful when working on the extractor itself) are in tool/ — see ../docs/AGENT_HANDOFF.md.
