How to prevent the cli to redownload the crates

[afidegnum]

This issue is reporting a bug in the code of Perseus. Details of the scope will be available in issue labels.
The author described their issue as follows:

running perseus build or perseus serve redownloads wasb-bindgen is there a way to stop the download to instead work with already downloaded crates?
For some of us using metered bandwidth, it can be costly.

The steps to reproduce this issue are as follows:

perseus build
perseus serve

Redownloading should only happen when the cached artefacts are no longer available. Assuming you're on Linux, what's the output of ls ~/.cache/perseus_cli/tools?

If this is happening continuously, it might be that your cache is being cleared very regularly, which might be to do with the amount of storage space left on your system? If that is the case, you could always copy the artefacts out of the cache path in the above command and provide paths to the binaries manually with the --wasm-bindgen-path and --wasm-opt-path arguments (both take a path afterward). The cache will contain folders for wasm-bindgen-<version> and wasm-opt-<version>. You should copy the appropriate binaries (wasm-bindgen for bindgen and bin/wasm-opt for wasm-opt) and then put those somewhere that won't be cleared. Then you could alias perseus="perseus --wasm-bindgen-path <path> --wasm-opt-path <path>" so you don't have to type that every time.
