Declaration files (*.d.ts) is not transformed.

[joshuaavalon]

I create an repository for the bug.

https://github.com/joshuaavalon/typescript-transform-paths-bug

After npm run build, lib\foo\index.js has

const a_1 = require("..\\a");

but lib\foo\index.d.ts has

import { A } from "@/a";
export declare type B = {
    b: A;
};

Edit:

{ "transform": "typescript-transform-paths", "afterDeclarations": true }

It transforms *.d.ts but it does not tranform .js

It seems that

    "plugins": [
      { "transform": "typescript-transform-paths" },
      { "transform": "typescript-transform-paths", "afterDeclarations": true }
    ]

works, but I don't know if it is supposed to be like this. We'll have to see if this is an issue with ttypescript or if it the expected behavior.

@danielpza I suspect it is this problem: Zoltu/typescript-transformer-append-js-extension#3 (comment)

TL;DR: If anything transforms an import or export declaration, the source visitor will skip it. By running your transformer after or afterDeclarations, you end up running after the source visitor, which means you get transformations that the source visitor makes.

Hi @MicahZoltu , uhm, leaving only:

    "plugins": [
      { "transform": "typescript-transform-paths", "after": true }
    ]

didn't work for me, the declaration files are not being transformed

17c149b - test didn't pass

Hmm, in that case this may be a different issue. I wonder if after is before or after afterDeclarations?
