How to integrate with a crate that uses main (binaries)?

[milesj]

I have a project named moon that provides a CLI written in Rust (using clap), and I want it to be installed through npm. Ideally this CLI is executed when yarn moon, npm moon, or npx moon, etc, is called.

I'm well aware of napi-rs working for libraries, but I'm completely lost on if it's possible for binaries. I have an open PR where I'm trying things: moonrepo/moon#56. Here's also a bit more context and direct links.

• The cli crate without napi integration https://github.com/milesj/moon/tree/release/crates/cli (I want this to be the build)
• The core crate with napi integration https://github.com/milesj/moon/tree/release/crates/core (it's empty for now as im trying to get the lib build working)
• The cli npm package https://github.com/milesj/moon/blob/release/packages/cli/package.json (see triples packages up a directory)
• And the napi build scripts https://github.com/milesj/moon/blob/release/package.json#L14

I haven't seen anything in the docs about this, so looking for guidance... if it's even possible.

Also, on a side note, I could not get js/dts generate working.

I'm looking at parcel-css which does exactly what I'm asking (as they use clap), and it looks like they just built it with cargo. Maybe I don't need n-api for this? But it would be nice if this was supported.

@milesj If you are building some executable binaries, and they are not expected to be required in JavaScript as a library, just build it via Cargo.

@Brooooooklyn Yeah I eventually figured that out. It would be nice if n-api CLI supported binaries, since the rest of the tooling (artifacts, CI actions, etc) are still beneficial.
