feat(wasm): Run Lumina in a Shared Worker (#265)
This PR introduces several features: either SharedWorker or Worker is spawned for the lumina instance, so that we no longer run in main "GUI" thread. NodeDriver replaces WasmNode and is responsible for steering actual lumina node running inside a Worker. Multiple tabs from the same context can access the same lumina instance. After spawning the shared worker, NodeDriver establishes a request-response communication channel over JS primitives. Node inside the SharedWorker has server-like infrastructure. onconnect event means that a new connection happened and we're supposed to use event.port[0] to communicate with a newly connected NodeDriver by responding with results of the command we're sent. Node inside Worker has simplified architecture, since it doesn't need to handle new tabs connecting, but otherwise works the same --------- Signed-off-by: Mikołaj Florkiewicz <[email protected]> Co-authored-by: Yiannis Marangos <[email protected]> Co-authored-by: Maciej Zwoliński <[email protected]>
