How to run binary script for the aliased installation?

[kwonoj]

Say I have 2 typescript versions installed in package.json

{
...,
  "devDependencies": {
    "tsc4": "npm:typescript@4.9.5",
    "typescript": "5.6.2",
  }
}

yarn tsc --version returns 5.6.2, which is expected. However, I'm not able to figure out how to run bin for the aliased tsc4 - something similar to yarn tsc4 --version (which doesn't work). Is there a syntax to specify specific dependency to run the binary? So far the only way I was able to find is yarn dlx -p tsc4@npm:typescript@4.9.5 tsc, but it seems to invoke temporary installation each time.

There is no yarn tsc4. An alias only renames the package. The binary is still tsc, so yarn tsc is 5.6.2.

PnP (default). Resolve the aliased package and run it:

yarn node "$(yarn node -p "require.resolve('tsc4/bin/tsc')")" --version

Want yarn tsc4? Add a script:

"scripts": {
  "tsc4": "node -e \"require('child_process').spawnSync(process.execPath,[require.resolve('tsc4/bin/tsc'),...process.argv.slice(1)],{stdio:'inherit'})\" --"
}

node-modules linker:

node node_modules/tsc4/bin/tsc --version

Pitfall: yarn dlx reinstalls each time. Use the paths above on the install you already have.
