Question 1

How do I use Workerize with async functions?

Accepted Answer

Simply export async functions in your worker code, and Workerize will automatically reflect them as async proxies, so you can call them with await in the main thread, as shown in the README example with synchronous functions that are handled asynchronously.

Question 2

Workerize vs Comlink: which should I choose?

Accepted Answer

Workerize is lighter and simpler for basic Web Worker proxying with minimal boilerplate, while Comlink offers more features like transferable objects and better error handling, but at a larger bundle size. Choose Workerize for straightforward tasks where size is critical.

Question 3

Can Workerize handle DOM updates from a worker?

Accepted Answer

No, because Web Workers cannot directly access the DOM. You must pass data back to the main thread and update the DOM there, which adds complexity for UI-heavy applications.

Question 4

What types of data can I pass to Workerize functions?

Accepted Answer

Only serializable data like primitives, arrays, and plain objects can be passed, as Web Workers use structured cloning. Functions or complex class instances will cause errors.

Question 5

How to integrate Workerize with Webpack?

Accepted Answer

Use workerize-loader, as recommended in the README banner, which integrates Workerize into Webpack's build process for better bundling and code splitting support.

Question 6

How do I handle errors in Workerize workers?

Accepted Answer

Errors thrown in the worker are propagated as rejected promises in the main thread, so you can use try-catch with async/await or .catch() on promises to manage them, though you may need to add custom error handling logic.
