Usage with path aliases

I’ve set up some custom path aliases in my ts-config: ie:

"paths": {
    "@themes": ["themes"],
    "@themes/*": ["themes/*"],
  },

Running this through rollup-plugin-ts results in the below error

[!] (plugin Typescript) TS2307: Cannot find module '@themes'.

Alright everyone, this issue has been fixed as part of v1.2.28 which will be released shortly. The problem was that rollup-plugin-ts always forced the baseUrl to ., which made path mapping resolve to wrong paths for other values for the baseUrl. @marjorg, I’ve tested it against the feature branch of your repo, and it built successfully. I don’t need access to the repo anymore. Thanks, that made everything a lot easier!

If it can help, i use @rollup/plugin-alias :

import alias from '@rollup/plugin-alias';
import tsconfig from './tsconfig.json';

function resolveEntries() {
  return Object.entries(
    tsconfig.compilerOptions.paths
  ).map(([find, [replacement]]) => ({ find, replacement }));
}

export default {
// ...
  plugins: [
    alias({
      resolve: ['.ts', '.tsx'],
      entries: resolveEntries(),
    }),
  ]
}
