Just tested switching my repository from Yarn Classic/v1 to pnpm (after having unsuccessfully tried using Yarn v2/PnP cause it breaks everything) and was surprised by the speed bump, less disk space usage and that everything continued to work fine. This appears to be the only caveat I have found with using pnpm so far; I’m not sure if this is pnpm’s fault or if pnpm simply hasn’t been accounted for by the prettier devs, but I’d really like to see prettier plugins work again in my IDE 😄 Edit: The plugin in question not working for me is prettier-plugin-package which sorts the package.json file and used to work before. Seeing that you’re having issues with a different plugin, this appears to be a pnpm<>prettier-vscode issue, not a plugin-specific one. Running prettier over the command line (with pnpx prettier --fix --plugin-search-dir=. package.json) works as expected.

As a workaround for this, you can create a .prettierrc.js in the monorepo and use require.resolve to generate the complete path to the plugin. Example:

module.exports = {
  plugins: [require.resolve("prettier-plugin-svelte")]
}
