threads.js VS partytown

Threads.js makes it pretty easy to spawn a thread pool and handle multi-threading workloads.

We did this via the npm threads wrapper and esbuild. We first moved all of our compute code into a new file with minimal imports, called imageCompare.worker.js. We then added a pre-compilation step with esbuild to compile this file into a bundle. We then spawn the worker using this generated file as a blob, and interact with it via the threads promise interface.

That latter one is in it's own process, and I also use multiple threads with the threads library.

This app has a memory leak where your worker threads are spawning out of control. You can verify this in Chrome DevTools Source tab: after you click the Generate button, you can see the worker threads spawning out of control until you close the process.

I'd advise that you do a better job at manually spawning and terminating the threads with the TFJS process. I've had success using this library in combination with TFJS: https://threads.js.org/

You can use it for everything. Even the compute tasks you can offload to worker threads using something like https://github.com/andywer/threads.js or you could create intensive modules in Rust and integrate using something like https://github.com/neon-bindings/neon

Web worker meets worker threads – threads.js\ (3 comments)

threads.js

Partytown is a lazy-loaded library to help relocate resource intensive scripts into a_ web worker, and off of the main thread. Its goal is to help speed up sites by dedicating the main thread to your code, and offloading third-party scripts to a web worker. — Source

Research Frameworks and Tools - Make sure to do your research on your current javascript framework and find out if it has a superset (eg React ->Nextjs, Svelte -> Sveltekit, Vue->Nuxtjs). They often come with many improvments and optimizations out of the box. There are also tools like Partytown which can vastly improve performance in some specific cases

has anyone had any luck with partytown?

It’s probably the insane amount of third party scripts like tracking and much more. Give partytown a try, might help you in the short run: https://partytown.builder.io

I assume you’re talking about https://partytown.builder.io/ — looks great! Only difference is not having a built in GDPR pop up, but that’s ok.
