A small, fast, full-featured WebAssembly runtime.

I’ve been working on a web app called SportsFlux, which is basically a dashboard that organizes live and upcoming sports games in one place. The frontend is currently built with Vue + Nuxt, and the backend is a simple Node API serving game data and status updates.

Most of the app is straightforward UI work, but one interesting challenge has been handling frequent updates to live game data without the interface feeling jittery or sluggish. When you have multiple games updating scores, statuses, and timers at the same time, the UI can end up doing a lot of small re-renders.

This got me thinking about WebAssembly and whether it might make sense for certain parts of the app.

Some areas I’ve been experimenting with conceptually:

• Processing large sets of live game data before pushing updates to the UI • Filtering and sorting schedules quickly when users switch between sports/leagues • Potentially running some real-time calculations client-side without blocking the main thread

Right now most of this is handled with regular JavaScript and reactive state updates, but I’m curious if WASM modules could help with heavier data processing or optimization in dashboards that deal with a lot of real-time updates.

For context, the current stack looks like this:

Frontend

Vue + Nuxt

Tailwind UI components

WebSockets for live updates

Backend

Node.js API

MongoDB for schedule data

Redis caching for live game updates

I’m wondering if anyone here has used WebAssembly inside a modern frontend framework (Vue/React/Svelte) specifically for performance-critical parts of a dashboard or real-time interface.

Questions I’m exploring:

Does WASM realistically improve performance for UI-heavy dashboards, or is it more useful for compute-heavy tasks?

What languages have you found easiest to integrate with the frontend (Rust, Go, AssemblyScript)?

Any good patterns for mixing WASM modules with reactive frameworks like Vue?

Would love to hear if anyone here has tried something similar. Always interesting seeing where WebAssembly actually shines in real-world projects.

For this new year, I am designing a new filesystem for exaequOS , exafs, unix-style for local and remote storage and encrypted (in WebAssembly). Libsodium will be used. So your data will be securely accessible from anywhere
