From the maintainer Li Haoyi: I'm putting a 1000USD bounty on this issue, payable by bank transfer on a merged PR implementing this.

Follow up of #3927.

The goal of this ticket is to find one real-world Typescript project and port it to Mill, similar to what we did with Mockito (as a comparison to Gradle), Netty (as a comparison to Maven), and Arrow (as a comparison for Gradle Kotlin).

• The project should be an existing medium-sized multi-module Typescript codebase with between 10-50 submodules
• Almost all code should compile and all tests should pass using Mill.
• There should be minimal code that does not compile/test in the Mill build, and each such part of the codebase must be justified as to why it cannot be supported in Mill
• The application code should be left entirely in place; the only change should be the addition of a Mill build

The end result should be a performance and functionality comparison of building and testing the project using Mill v.s. the existing build tool

@lihaoyi I see someone is already working, is the issue tied to assignment or anyone can work!?

@b4s36t4 anyone can work, following the policy stated in https://github.com/orgs/com-lihaoyi/discussions/6. In case of multiple PRs the choice is up to my discretion
