Handling wasm-pack before pnpm install

[d-corler]

I have a monorepo that includes both Rust and JS packages. One of the JS packages depends on wasm-pack. I’m running into an issue because pnpm install runs before I can build the WebAssembly package, and leading to this issue:

ERR_PNPM_WORKSPACE_PKG_NOT_FOUND  In shared/test-schemas-ts: "test-schemas-wasm@workspace:*" is in the dependencies but no package named "test-schemas-wasm" is present in the workspace

I’ve tried using .pnpmfile.cjs as an attempt to build before the resolution, but it doesn’t seem possible to reference a package that doesn’t exist initially.

What are your advices ?

@d-corler Yeah this is a tricky situation, since the "install deps" action will always run before the "run task" action. There's no way to circumvent this.

Is it possible to stub the wasm-pack package with some empty shell/files so that the pnpm resolution works for the initial install?

Yes, maybe with a decoy package.json

📁 shared
│
└── 📁 example project
    │
    ├─── .moon.yml
    │
    ├─── package.json (decoy)
    │
    └─── 📁 pkg (out of wasm-pack)
         │
         ├─── package.json
         │
       [...]

# Decoy
{
  "name": "example-wasm",
  "files": [
    "pkg/example_wasm_bg.wasm",
    "pkg/example_wasm.js",
    "pkg/example_wasm.d.ts"
  ],
  "main": "pkg/example_schemas_wasm.js",
  "types": "pkg/example_schemas_wasm.d.ts"
}

We can keep a "sync" by adding a script to copy and tweak it from pkg.
