Description

There is a WIP PR #16371 to implement Webpack 5 but I could not find an issue tracking it and I'm opening this one so that implementation and timeline can be discussed and followed by the community.

Describe the solution you'd like

Support Webpack 5 once released. (currently it's in beta)

Describe alternatives you've considered

no alternative considered

@alan-agius4 out of curiosity, do you guys have a timeline to try out the beta? I suppose it would be good to validate that webpack 5 is in a good shape for Angular CLI while it's still in beta

We already tried to test Webpack 5 a couple of times #16371 and #13348

Will this issue also include the module federation as discussed in https://github.com/sokra/slides/blob/master/content/ModuleFederationWebpack5.md?
If this is the case, then I'm very exited! The work that's been put into this will in my opinion revolutionize how we build frontend applications.

As support to Webpack 5 and support to Module Federation are two different streams that will probably not be implemented in the same PR we are tracking Module Federation support on issue #17556

@alan-agius4 is there a fork somewhere where a development is done? may be community can contribute.

Unfortunately, Webpack 5 has a lot of breaking changes and therefore adding support for it is not trivial feat.

@clydin is working on this and has already landed a number of small PRs to make this happen gradually.

Can you use the current master branch if you are interested in contributing in any way.
