Hi! I’m importing a library that doesn’t have module declarations. I created a

types/index.d.ts

file, and I added it to

tsconfig.json

. Here is the file:

{
  "compilerOptions": {
    "strict": true,
    "outDir": "bin",
    "target": "es2016",
    "module": "commonjs",
    "moduleResolution": "node",
    "sourceMap": true,
    "experimentalDecorators": true,
    "pretty": true,
    "noFallthroughCasesInSwitch": true,
    "noImplicitReturns": true,
    "forceConsistentCasingInFileNames": true,
    "esModuleInterop": true
  },
  "include": [
    "infra",
    "types"
  ],
  "exclude": [
    "node_modules",
    "vendor",
    "dist"
  ]
}

I have the impression that Pulumi is ignoring my config. Does anybody see what may be wrong on my setup? VSCode’s TS server finds the

.d.ts

declaration and doesn’t show the error I get when running

pulumi up

.

How have you declared the module in

types/index.d.ts

?

This is the code:

declare module "@bref.sh/layers" {
	function fpmLayerArn(
		region: string,
		version: string,
		architecture?: string,
	): string;
}

I think the issue is with the module you've declared in

types/index.d.ts

and not your TS configuration. Also I see that the original source contains JSDoc for that function which should provide the type hints that your module is trying to provide. Are you simply trying to add type-safety for that function or trying to fix some other problem?

No, i’m just trying to import it, and TS fails because it doesn’t have a types declaration

So I was wrong about it not having to do with your

tsconfig.json

file. Your module declaration is indeed correct. You might try

include: ["***/**.ts"]

in your config.
