fix: fix missing ESM type definition file

[mizdra]

Background

The dedent package exports only CJS type definition files (./dist/index.d.ts). Therefore, if users try to import dedent as an ESM, tsc will not find the type definition file.

How to reproduction:

$ git clone https://github.com/mizdra/reproduction-dedent-fix-missing-esm-type-definition
$ cd reproduction-dedent-fix-missing-esm-type-definition
$ npm i
$ npm run build

> app_name@0.0.0 build
> tsc -p tsconfig.build.json

src/index.ts:5:15 - error TS2349: This expression is not callable.
  Type 'typeof import("/Users/mizdra/src/github.com/mizdra/reproduction-dedent-fix-missing-esm-type-definition/node_modules/dedent/dist/dedent")' has no call signatures.

5   console.log(dedent`text`);
                ~~~~~~


Found 1 error in src/index.ts:5

src/index.ts:

import dedent from 'dedent';

export function run() {
  // eslint-disable-next-line no-console
  console.log(dedent`text`);
}

This problem can also be detected by publint.

Solution

To solve this problem, I added the ESM type definition file (./dist/dedent.d.mts).

I have also confirmed that this patch allows tsc to pass.

$ npm i -S ../dedent
$ npm run build

> app_name@0.0.0 build
> tsc -p tsconfig.build.json

$ echo $?
0

Ah, thanks @mizdra!

[JoshuaKGoldberg]

Published in dedent@1.4.0, thanks!

[mizdra]

@JoshuaKGoldberg Thanks for the quick response! However, it seems that dedent.d.mts is not included in the published package.

• https://www.unpkg.com/browse/dedent@1.5.0/dist/

Did you forget to yarn run build before publish?

[JoshuaKGoldberg]

Ah, no, it's missing in package.json files. Adding now.

[mizdra]

Oh, I forgot to include it in files field of package.json. Sorry!

[JoshuaKGoldberg]

Funny how the little old things like that get in the way, right after figuring out the new ESM exports... Fixed in dedent@1.5.1 / https://github.com/dmnd/dedent/releases/tag/v1.5.1.

[mizdra]

Has 1.5.1 already been released? It seems not to have arrived at npmjs.com yet.

https://www.npmjs.com/package/dedent

[JoshuaKGoldberg]

Hmm, try again? Might be a caching thing: https://www.npmjs.com/package/dedent/v/1.5.1

(the publish took suspiciously long on my end...)

[mizdra]

Successfully installed. I have confirmed that the problem with the type definition file has also been resolved.

Thank you!
