Description

Reproduction link

https://github.com/iCodeBIT/vendorHashTest

Steps to reproduce

  1. Delete a .vue file in /src/components directory, like Hello2.vue.
  2. npm run build;
  3. After building, we can see from "git status" that a new vendor.js is generated.

What is expected?

The hash value of vendorjs should NOT change.

What is actually happening?

The hash value of vendorjs has changed.

The project is generated from vue-template/webpack. In my point of view, vendorjs is extracted from node_modules, modifications in /src/components should not affect vendorjs. Is there anything wrong with the webpack config?

Direção de pesquisa
Investigate the webpack configuration in the vuejs templates/webpack repository, specifically the chunk splitting logic for vendor.js. Look at how CommonsChunkPlugin or splitChunks is configured to separate node modules from app code. The reproduction repo at https://github.com/iCodeBIT/vendorHashTest shows that deleting a component file changes the vendor hash, which suggests that the vendor chunk includes references to the app code or the hash is computed over all modules. Compare with expected behavior where vendor hash should be stable. Check if there is a linked PR or maintainer response in the issue comments (4 comments) for clues.
