pnpm 7.29.0

v7.29.0

on Node.js NPM

Minor Changes

• A new setting is now supported: dedupe-peer-dependents.

  When this setting is set to true, packages with peer dependencies will be deduplicated after peers resolution.

  For instance, let's say we have a workspace with two projects and both of them have webpack in their dependencies. webpack has esbuild in its optional peer dependencies, and one of the projects has esbuild in its dependencies. In this case, pnpm will link two instances of webpack to the node_modules/.pnpm directory: one with esbuild and another one without it:

  node_modules
    .pnpm
      webpack@1.0.0_esbuild@1.0.0
      webpack@1.0.0
  project1
    node_modules
      webpack -> ../../node_modules/.pnpm/webpack@1.0.0/node_modules/webpack
  project2
    node_modules
      webpack -> ../../node_modules/.pnpm/webpack@1.0.0_esbuild@1.0.0/node_modules/webpack
      esbuild
  

  This makes sense because webpack is used in two projects, and one of the projects doesn't have esbuild, so the two projects cannot share the same instance of webpack. However, this is not what most developers expect, especially since in a hoisted node_modules, there would only be one instance of webpack. Therefore, you may now use the dedupe-peer-dependents setting to deduplicate webpack when it has no conflicting peer dependencies (explanation at the end). In this case, if we set dedupe-peer-dependents to true, both projects will use the same webpack instance, which is the one that has esbuild resolved:

  node_modules
    .pnpm
      webpack@1.0.0_esbuild@1.0.0
  project1
    node_modules
      webpack -> ../../node_modules/.pnpm/webpack@1.0.0_esbuild@1.0.0/node_modules/webpack
  project2
    node_modules
      webpack -> ../../node_modules/.pnpm/webpack@1.0.0_esbuild@1.0.0/node_modules/webpack
      esbuild
  

  What are conflicting peer dependencies? By conflicting peer dependencies we mean a scenario like the following one:

  node_modules
    .pnpm
      webpack@1.0.0_react@16.0.0_esbuild@1.0.0
      webpack@1.0.0_react@17.0.0
  project1
    node_modules
      webpack -> ../../node_modules/.pnpm/webpack@1.0.0/node_modules/webpack
      react (v17)
  project2
    node_modules
      webpack -> ../../node_modules/.pnpm/webpack@1.0.0_esbuild@1.0.0/node_modules/webpack
      esbuild
      react (v16)
  

  In this case, we cannot dedupe webpack as webpack has react in its peer dependencies and react is resolved from two different versions in the context of the two projects.

Patch Changes

• The configuration added by pnpm setup should check if the pnpm home directory is already in the PATH before adding to the PATH.

  Before this change, this code was added to the shell:

  export PNPM_HOME="$HOME/Library/pnpm"
  export PATH="$PNPM_HOME:$PATH"

  Now this will be added:

  export PNPM_HOME="$HOME/Library/pnpm"
  case ":$PATH:" in
    *":$PNPM_HOME:"*) ;;
    *) export PATH="$PNPM_HOME:$PATH" ;;
  esac

• Add skipped status in exec report summary when script is missing #6139.

• pnpm env -g should fail with a meaningful error message if pnpm cannot find the pnpm home directory, which is the directory into which Node.js is installed.

• Should not throw an error when local dependency use file protocol #6115.

• Fix the incorrect error block when subproject has been patched #6183
