Hi,
I am trying to use pulumi (a deployement tool, doesn’t matter GitHub - pulumi/pulumi: Pulumi - Universal Infrastructure as Code. Your Cloud, Your Language, Your Way 🚀) with nix as much as possible. I have a working environment with plain javascript: I have packaged @pulumi/pulumi with node2nix, add it to NODE_PATH and it works fine. Now we have some typescript scripts (disclaimer: I am a javascript+typescript noob). I put tsc typescript compiler in PATH but pulumi still can’t find the javascript modules. Apparently typescript doesn’t care about NODE_PATH and the config is encoded in tsconfig.json.
My question is how do I tell typescript where to look for files in a nix-friendly way ? I dont want to generate the tsconfig.json to point to a path in the /nix/store because it’s inconvenient. Also I would like to let the people the possibility to still use npm/tsc and not nix. Seems like one can provide fallback paths to tsc but I was not able to make it work. What I do now is to pass a stable path “baseUrl” = “/tmp/node_modules_by_nix” that points to a node_modules folder in the nix store. The symlink /tmp/node_modules_by_nix when entering nix develop. It works, it is kinda good enough but it doesn’t feel right:
{
"compilerOptions": {
"baseUrl": "/tmp/node_modules_by_nix" ,
"strict": true,
"outDir": "bin",
"target": "es2016",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
"experimentalDecorators": true,
"pretty": true,
"noFallthroughCasesInSwitch": true,
"noImplicitReturns": true,
"forceConsistentCasingInFileNames": true
},
"files": [
"index.ts"
]
}
Ideally I would like to export an environment variable similar to NODE_PATH, e.g., TSC_PATH to tell typescript where to look for modules. I am not sure what’s the best approach on nixos. There is no entry in the nixpkgs manual for typescript, could be worth adding.
Cheers,
