I have a file structure like this (simplified):
src/
index.ts
lazy.ts
something.ts
webpack.config.js
In index.ts I import lazy.ts using async import. In both modules I import something.ts. Because something.ts is bundled with index.ts in the main chunk I have to tell webpack that it should use the same module cache for lazy.ts. Or did I understand something wrong? So I specified a chunk in webpack.config.js that depends on the main chunk and has the lazy.ts entry. Now I get three chunks instead of two because webpack bundles lazy.ts twice. How can I solve that?
