Thanks for filing a feature request! Please fill out the TODOs below.

Feature

Option to turn off and clear automatic module caching to ~/.cache/wasmtime/modules/wasmtime-.

Benefit

When testing the contents of ~/.cache/wasmtime/modules/wasmtime- can continue to grow exponentially.

Implementation

Add an option to

  1. Run the .wasm file directly without caching
  2. Option to automatically remove the cached folders and files after the .wasm file is run
  3. Option to remove the contents of wasmtime cached modules, e.g., with Bun we can do bun pm cache rm

Alternatives

Unknown.

You can disable the cache globally by writing

[cache]
enabled = false

to ~/.config/wasmtime/config.toml.

To disable the cache for a single invocation use -C cache=n. To remove the cache you can remove the ~/.cache/wasmtime directory.

@bjorn3 That works. I had to create the ~/.config/wasmtime directory and config.toml file. Is this documented somewhere here?

The wasmtime config new command creates this file with the default configs filled in. It also prints the path to the config file it created.

Thanks.

Would help if the content of the wasmtime "guide" was conspicuously in the README.

I still don't know what wasmtime-min does and how to use that executable.

It is the wasmtime executable, except with every optional feature (like wasi support) disabled and optimized for size. You should ignore it unless you actually need a tiny wasmtime binary for some reason.

Testing.

I guess that explains why wasmtime-min doesn't execute code compiled with javy.
