error TS7016: Could not find a declaration file for module 'threads'

[jambudipa]

I am not sure how to configure my node app to support TypeScript when using this package. The compiler complain:

error TS7016: Could not find a declaration file for module 'threads'. 'node_modules/threads/index.mjs' implicitly has an 'any' type.
Try npm i --save-dev @types/threads if it exists or add a new declaration (.d.ts) file containing declare module 'threads';,

I have tried both of those things, neither work. I am using npx nodemon src/index.ts to run my app and the threads.d.ts file is in the same folder as its usage.

What can I do?

index.mjs is missing its type definitions. The file is declared in the exports part of package.json:

threads.js/package.json

Lines 24 to 41 in 0d1a882

	"exports": {
	".": {
	"require": "./dist/index.js",
	"default": "./index.mjs"
	},
	"./observable": {
	"require": "./observable.js",
	"default": "./observable.mjs"
	},
	"./register": {
	"require": "./register.js",
	"default": "./register.mjs"
	},
	"./worker": {
	"require": "./worker.js",
	"default": "./worker.mjs"
	}
	},

so any tool that started evaluating exports instead of main or module:

threads.js/package.json

Lines 6 to 7 in 0d1a882

	"main": "dist/index.js",
	"module": "dist-esm/index.js",

will have broken types now.

PR #470 is a fix; for now I'm applying it in my project via patch-package.
