Migrate workbox-webpack-plugin to TypeScript

[jeffposnick]

Placeholder to track the migration.

Is there any update on the state of the migration in this repo?

I'd be more than happy to help, and submit a PR or two migrating packages to TypeScript. Just point me in the right direction :)

Not for workbox-webpack-plugin at this time.

I am in the middle of migrating workbox-build to TypeScipt (#2477, WIP code at https://github.com/GoogleChrome/workbox/compare/wb-build-ts). That is a more involved migration, as it's also going to including switching from joi to something like https://github.com/gristlabs/ts-interface-checker or https://github.com/pelotom/runtypes to use the TypeScript parameter definitions as the source of truth for runtime option validation.

Once #2477 is complete, I think the workbox-webpack-plugin migration should be more straightforward. If you're looking to contribute at that point, that would be great!

[roikoren755]

Sounds good!
Like I said, I'd be more than happy to help with the migration, not only for workbox-webpack-plugin, but for other packages in this repo as well. Anything you need help with, especially if it has to do with migrating to TypeScript, just let me know :)

I see #2477 was merged recently 🎉.

Is there any work currently being done to migrate workbox-webpack-plugin to TypeScript?

If not, I can take a look at it over the weekend, get something started :)

I will say in advance, from my experience, webpack types are incompatible between v4 and v5, and migrating this package to TypeScript might mean having to pick one over the other...

[jeffposnick]

Thanks for following up on your initial offer!

Feel free to take a look, and even if you're not able to fully take this on, I'm happy to continue a WIP PR at some point.

The nuance of incompatible webpack v4 and v5 types is an interesting problem... I'm going to ask some colleagues if they have ever run into similar problems. I wonder if adding in explicit devDependencies on both webpack-v4 and webpack-v5 and then explicitly importing both of their exported types, along with some conditional casting, would end up being a path forward.

Is there any update on this?
The typings published for the webpack plugin is old and I think is incomplete as well.

I am making a custom plugin for angular and while it works in practice, the only problem is that typescript keeps complaining so I have to silence it.

[roikoren755]

Sorry, I haven't had the time to push this forward on my end...
If anyone is interested in taking the helm on this and continue with my base branch, you are more than welcome.
Otherwise, I'll try and find the time to work on it

@tropicadri from the core Workbox engineering team is actively working on getting the open PR cleaned up: #2882

[tropicadri]

The PR is ready for review. It should be live relatively soon.
