  • Examples
  • Usage

Examples

There are multiple examples available demonstarting the features described above (listed from simpler to more advanced):

• WorkerTask: Hello World: html, ts, worker
• WorkerTaskDirector: Hello World: html, ts, worker
• WorkerTask: Inter-Worker Communication: html, ts, Worker: 1 and 2

Try out all examples here: https://kaisalmen.github.io/wtd

Usage

This shall give you an idea how you can use module worker with WorkerTask (derived from WorkerTask: Hello World):

// let WorkerTask create the worker
const workerTask = new WorkerTask({
    taskName,
    workerId: 1,
    workerConfig: {
        $type: 'WorkerConfigParams',
        url: new URL('./HelloWorldWorker.js', import.meta.url),
        workerType: 'module',
    },
    verbose: true
});

try {
    // cteates and connects the worker callback functions and the WorkerTask
    workerTask.connectWorker();

    // execute without init and an empty message
    const resultExec = await workerTask.executeWorker({
        message: WorkerTaskMessage.createEmpty()
    });

    // once you awaited the resulting WorkerTaskMessage extract the RawPayload
    const rawPayload = resultExec.payloads?.[0] as RawPayload;

    // log the hello from the HelloWorldWorker
    console.log(`Worker said: ${rawPayload.message.raw?.hello}`);
} catch (e) {
    // error handling
    console.error(e);
}
