Jimp.write(path) has weird typescript type ${string}.${Extension}

[ma-zal]

Expected Behavior

I expect standard string as datatype of path input parameter of Jimp.write function.

Current Behavior

Used complicated (and on many places incompatible) data type${string}.${Extension} for input parameter path.

Need to explicitly retype by ugly as '${string}.${string}'

Failure Information (for bugs)

Steps to Reproduce

const icon = await Jimp.read(sourceImgPath);
const writePath = path.join(__dirname, 'myfile.png');
await icon.write(writePath); // Error: Argument of type 'string' is not assignable to parameter of type '`${string}.${string}`'.ts(2345)

I think this is even bigger...
I want to resize a temporary file inplace with a filename like: /tmp/67f63be03de2e62bccbab3400
However something like

img.resize({w: smallestLength}).write(path as `${string}.${string}`)

==>
Fatal: no ErrorError: Unsupported MIME type: null
at Jimp.getBuffer (/usr/local/opt/backend/node_modules/@jimp/core/src/index.ts:426:15)
at Jimp.write (/usr/local/opt/backend/node_modules/@jimp/core/src/index.ts:503:20)
at resizeImage (/usr/local/opt/backend/src/lib/resizeImage.ts:16:44)

does not work as the actual implementation

async write(path, options) {
   const mimeType = mime.getType(path);
   await writeFile(path, await this.getBuffer(mimeType, options));
}

really really needs it to be

`${string}.${string}`

I probably should be possible to set the mimeType by the options and only infer the type by path when not explicitly setting the option.

Workaround:

await writeFile(
      path,
      await img.resize({h: smallestLength}).getBuffer(img.mime as typeof JimpMime[keyof typeof JimpMime])
    )

here again you can't pass just any string
