描述

This time it's @sokra who told me this is probably the place to open an issue.

  • Operating System: Windows 10
  • Node Version: 12.16.2
  • NPM Version: 6.14.4
  • webpack Version: 5.0.0-beta.22
  • webpack-dev-server Version: 3.11.0
  • Browser: Chrome 84.0.4147.105, Firefox 79.0, Edge 84.0.522.48
  • This is a bug

Code

https://github.com/codepunkt/module-federation-examples/tree/dynamic-host-remote

Expected Behavior

Using webpack-dev-server instead of webpack should still support module federation with additional content tacked onto the remoteEntry by defining it as an additional entry.

Actual Behavior

Running "yarn start" to start webpack-dev-server breaks module federation and thus breaks the app in development mode.

For Bugs; How can we reproduce the behavior?

  1. clone repository
  2. ensure you're on branch "dynamic-host-remote"
  3. run yarn on repo root
  4. go into "dynamic-host-remote" directory
  5. run yarn start in "dynamic-host-remote" directory
  6. open localhost:3001 in the browser
  7. encounter an error in the browser console that happens when executing app2/remoteEntry.js with the additional contents that were added to this entrypoint by webpack-dev-server
  8. OPTIONAL: run yarn build && yarn serve and revisit localhost:3001 to see production build working just fine.

研究方向
The issue includes a reproduction repository at https://github.com/codepunkt/module federation examples/tree/dynamic host remote. Investigate how webpack dev server handles multiple entrypoints and why it conflicts with module federation remoteEntry loading. Look at the webpack dev server source code, particularly the part that injects its client entry, and compare with the production build path. Relevant comments may provide further clues.
