Migrate to TypeScript

[mpeyper]

What:

Migrate to TypeScript.

Why:

@kentcdodds approached the Open Source Raid Guild with a quest to migrate this repo to TypeScript.

How:

Minimal upgrade to introduce type safety and generate type definitions while adhearing to good TypeScript practices. We want to keep functional changes within the plugin as little as possible.

Kent suggested that it would be fine to follow the approaches taken in babel-plugin-codegen when it was migrated when it was migrated.

This PR will be kept in a draft state while the raid is in progress so that the repo maintainers can see the current state of the migration.

The repo has been forked for the raid party to use for our own planning and coordination and planning, but you are welcome to participate in the issues and pull requests that occur there if you wish.

You can also keep track of the raid stats on our (work-in-progress) website.

Finally, you are invited to join us in the ⚔️-OSS-RAID section of the KCD discord server to chat with us about the changes and keep up to date with the work happening within the raid party.

• Main Quest:
  • Setup project with TypeScript dependencies, config and scripts
  • Migrate src files
  • Migrate __test__ files
  • Add necessary .d.ts files to root
  • Cleanup
• Side Quests:
  • Refactoring (if applicable)
  • Set up Github Actions (if it benefits the Raid)

This looks great! I just have one comment.

[mpeyper]

@kentcdodds, I've marked this as ready for review as all the files have been migrated, with tests passing and no linting errors.

At this point of the raid, we welcome you to leave any comments or raise any concerns for the raid party to take on.

This change hasn't been published to npm, has it? Inspecting https://unpkg.com/browse/babel-plugin-preval@5.0.0/package.json I don't see any references to types

[kentcdodds]

Ah yeah, looks like this repo was never updated to use github actions to auto-release stuff. Bummer. I'm afraid I don't have the bandwidth to work on this :(

[NMinhNguyen]

Is there anything I can do to help set up publishing? I could presumably copy the action definition from another one of your repos?

[mpeyper]

Hi @kentcdodds, if you want, I can look at getting a pipeline set up for you. Would still need someone to merge a PR for it (I understand that you may not have the bandwidth for even that right now)

[kentcdodds]

I can merge a PR 👍

[mpeyper]

@NMinhNguyen you offered first, so happy to let you take it. I will review the PR for it if you want. You can likely follow what has been done in babel-plugin-macros as a template.

[NMinhNguyen]

@mpeyper thanks for the pointer! I can have a look a bit later but if you don't see a PR from me in the next 24 hours, feel free to raise one yourself :)
