ts-transform-paths with rollup-plugin-typescript2

[iliyaZelenko]

Hi, i tried this lib because my .d.ts files files generated with paths that have aliases:

import Component from '~/path1/path2';
import { Component2 } from '~/path2';

I stumbled upon your package.

I tried to use this package like with rollup:

import transformPaths from '@zerollup/ts-transform-paths'

and in my rollup plugin property:

typescript({
  clean: true,
  transformers: [service => ({
    before: [
      transformPaths(service.getProgram())
    ],
    after: []
  })]
}),

I wanted to do as in the code in this example. (pre-header example)

But I get an incomprehensible error:

Can you suggest something? Perhaps there are other packages for this?

Can you provide full example with tsconfig and etc?

I use https://github.com/cevek/ttypescript#rollup to inject plugin and include it into config in my demo

@zerkalica my project: https://github.com/iliyaZelenko/tiptap-vuetify

I can try with ttypescript but preferably without this and the option that I use.

[zerkalica]

I check your project with ttypescript, it works fine, just use.

Sorry, i have no time to dig into buggy rollup plugin (probably problem in it) or your rollup config.

@zerkalica thanks for testing this package with ttypescript, I will use it.

Thank you for your package. I will report it works for me or not.

[iliyaZelenko]

Everything is working! Thanks, it really helped me.
