Repro: pnpm doesn't correctly install transitive dependencies:

pnpm-transdep-issue

pnpm doesn't install transitive dependencies (pnpm#7594)

Note: this is working as intended; see this comment on pnpm#7594, this explanation of pnpm's flat node_modules structure, and this explanation of pnpm's "strict" enforcement that packages references directly must be listed explicitly as package.json "dependencies."

Github Actions repro

See this example run:

• npm succeeds
• pnpm fails with error:

  deckgl-react.ts(1,20): error TS2307: Cannot find module '@deck.gl/react/typed' or its corresponding type declarations.
  

For some reason, pnpm install deck.gl fails to install deck.gl's dependencies (original discussion: deck.gl#8456)

Also note that node_modules/@deck.gl exists in the npm job but not in the pnpm job.

Docker repro

build() {
    docker build --build-arg npm=$1 -t pnpm-transdep-issue --progress=plain .
}
build npm   # ✅ works
build pnpm  # ❌ fails

See Dockerfile:

• deck.gl depends on @deck.gl/react
• npm install deck.gl works as expected (installs @deck.gl/react)
• pnpm install deck.gl fails to install @deck.gl/react
  • As a result, compiling deckgl-react.ts failes:

    Cannot find module '@deck.gl/react/typed' or its corresponding type declarations.
    

The build command also runs ls -l node_modules, and we see that the npm version includes node_modules/@deck.gl/… while the pnpm version doesn't.
