Question

I use Pulumi in a Yarn 3 monorepo Pulumi doesn t like yarn s package hoisting so I need to add this to the pulumi program s package json ``` installConfig hoistingLimits workspace ``` Not super happy with it as we have dozen of other packages in the monorepo and disabling hoisting make us pay some penalty mostly longer CI builds and bigger FS usage for node modules Yarn 3 has a new feature that replaces node modules directories completely It s amazingly fast We do not even need to run yarn install anymore cf To use it I need to do this before running the Pulumi program ```require pnp cjs setup ``` However I cannot find a way to do this in a TypeScript program Guess I should configure TS to allow importing cjs files and import it using an import statement in the TS file What about native support for Yarn s PnP in Pulumi Would you accept such a PR If so is this the right place

Oh you did seriously try it I d be happy finding a way for the pulumi program to be able to find the pulumi packages i am already refactoring inlined lambdas as separate packages gt finding the Pulumi plugins is iterating over the `node modules` folder in Go code to find the plugin binaries This is definitely blocking

<https www pulumi com docs reference pkg nodejs pulumi pulumi |The docs> says pulumi can be installed with yarn This leads people to believe that it works with yarn And people usually switch from npm to yarn to benefit from hoisting But as soon as they try to hoist packages or PnP it doesn t work Pulumi only works with the node modules linker and when disabling hoisting for the whole monorepo or at least for the package that contains the pulumi program I d be happy to provide a PR to help others but I am not sure when this belongs

we use yarn 3 as well but use the node modules fallback option over pnp That works never gotten pnp to work
