How can I split my project into multiple WASM modules and load them dynamically?

[myrpg-fun]

Is it possible to split my Rust/WASM code into separate bundles and load them on demand?

For example, I have a Rust workspace with two crates — statistics and users.

I’d like to compile each into its own WASM module (the statistics bundle is only ~500 KB, but the full build is currently ~3 MB) and then dynamically load only the module I need.

on page /stat/:id - statistic bundle
on page /users/ - users admin bundle

How can I set this up?

Automatic binary splitting and lazy-loading are not trivial for WebAssembly. The framework does have built-in support for this (see #3477 and the linked example) but the build tooling is lagging behind a bit. (It should be coming some time in the near future -- say this summer, roughly.)

Ooooh! That’s good news.

Is there a way to try this out in an SSR Leptos application?

Not yet, unfortunately.

Just noting here - v0.8.5 just released with full wasm splitting, woot
