I can't find a way to generate d.ts and d.ts.map files using webpack. babel-loader only generates js and js.map files. I also need d.ts and d.ts.map files (which I was able to generate using tsc command) as shown in this picture:

Here is a minimal repo that contains all the settings: https://github.com/stavalfi/lerna-yarn-workspaces-example

I moved to Lerna + yarn. One of my packages is core (will be used in other packages) which is written in TS and JS.

I'm using webpack 4,babel-loader 8 for ts-to-js.

The other packages are trying to find type definitions and implementation of my core package but I was only able to generate index.js and index.js.map with webpack:

[It only infects typescript library creators]

if the code base contains absolute paths (by configuring tsconfig.json and webpack), then the typescript compiler will generate all the d.ts files with the same absolute paths that are useless because my lib consumers can't do a thing with them.

Every library that I saw are doing one of the following:

1. creating their own single-file.d.ts file manually
2. using relative path in their code base so the output d.ts files also contain relative paths.

Clearly, both alternatives suck.

1. creating a single d.ts file (there will be no imports).

I couldn't find a working library for that.

1. not sure if it's possible: before running ts-loader, we need to run a magic babel-plugin to transform every absolute path to a relative by looking in the webpack-resolve-module section in webpack.config file.

I created a library that generates broken d.ts files with absolute paths:
