What is the best way to specify a function parameter as the `QUnit` type using TypeScript in conjunction with QUnit?

In my project, which is partially written in TypeScript and licensed under MIT, I am utilizing QUnit. I have some TypeScript functions that require QUnit as a parameter, and I would like to define their types based on its interface from the typings.

For example:

import { QUnit } from "qunit";

export function run_tests(q: QUnit)
{
    q.module((a) => { ... });
}

However, I encountered an error when attempting to do so:

tsc --project lib/typescript/www/tsconfig.json
src/ts/web-fc-solve-tests.ts(12,23): error TS2306: File '/home/shlomif/progs/fre
ecell/git/fc-solve/fc-solve/site/wml/node_modules/@types/qunit/index.d.ts' is no
t a module.

You can find the code (note the branch) here: https://github.com/shlomif/fc-solve/tree/qunit-typescript - located under the fc-solve/site/wml subdirectory.

This is my tsconfig.json:

{
  "compilerOptions": {
      "baseUrl": ".",
      "esModuleInterop": true,
      "module": "amd",
      "moduleResolution": "node",
      "noImplicitReturns": true,
      "outDir": "../../../lib/out-babel/js",
      "paths": {
          "big-integer": ["node_modules/big-integer/BigInteger.d.ts"],
          "qunit": ["node_modules/@types/qunit"]
      },
      "target":"es6"
  },
  "include": ["../../../src/ts/**/*.ts"]
}

Any assistance would be greatly appreciated.

Answer №1

To access the correct typings, simply install the @types library for qunit using npm. You can then avoid including the import statement entirely.
