worker_runtime library

Web-only runtime for building a custom tokenize Web Worker entry point.

A backend that ships its own prebuilt worker (because it can't live in the core package, e.g. shiki_flutter_native_engine, which pulls a native build hook) writes a Flutter-free entry whose main() is a single call to runTokenizeWorker, passing the engine to tokenize with. That reuses the one shared message loop, so per-engine workers can't drift.

Pair it with package:shiki_flutter/engine.dart (the Flutter-free tokenizer) and, if the entry needs the JSON codec directly, worker_protocol.dart.

Web-only: imports dart:js_interop, so only ever reached from a dart compile js worker entry.

Functions

runTokenizeWorker(ShikiHighlighterEngine engine, {Future<void> prepare()?}) → void

Runs the tokenize-worker message loop, tokenizing every request with engine. Call it from a Flutter-free worker entry's main().
