layers

layer

Creates browser worker layers by combining the default WorkerPlatform with a spawner for Worker, SharedWorker, or MessagePort instances.

When to use

Use when you need both the browser WorkerPlatform and a Spawner from one layer.

Details

The spawn callback receives the numeric worker id and may return a Worker, SharedWorker, or MessagePort.

Gotchas

Scope finalization sends the worker close protocol over the port. Dedicated workers created by spawn are not terminated by this layer.
