Switch to TypeScript

[stackdumper]

As for me, TypeScript is much more convenient and has better integrations for code editors. I believe switching to TS would allow Verdaccio to evolve faster and would encourage contributors and, especially, plugin developers.

We are working on it, first step #1164
It won't happen soon. After release v4.

If anyone is willing to contribute on this, a next step would be

• https://github.com/verdaccio/flow-types/issues/39 (feat: add typescript types flow-types#45)
• Migrate https://github.com/verdaccio/verdaccio/blob/master/types/index.js
• Migrate progressively small projects (streams, plugins, local-storage, htpasswd)

We need to find the way to keep flow and typescript for a while until the migration is done.

Update (January 2019)

We just created a custom babel preset, that allow us to switch to Flow or Typescript using Babel 7, more details on this repo.

Update (July 2019)

Migration is in progress in this PR #1374 , core project has been already converted, in progress unit testing.

Working on this by steps

• verdaccio-memory repo to Typescript (https://github.com/verdaccio/verdaccio-memory)
• verdaccio-auth-memory repo to Typescript (https://github.com/verdaccio/verdaccio-auth-memory)
• @verdaccio/streams (https://github.com/verdaccio/streams)
• verdaccio-audit
• verdaccio-htpasswd feat: migrate to typescript verdaccio-htpasswd#41
• @verdaccio/local-storage
• UI moved to https://github.com/verdaccio/ui @priscilawebdev Refactor: migrating Flow to Typescript ui#47
• @verdaccio/file-locking https://github.com/verdaccio/file-locking @priscilawebdev

✔️ List

• ✔️ Migrated all direct dependencies to Typescript (verdaccio-audit, verdaccio-htpasswd, @verdaccio/local-storage and @verdaccio/streams )
• ✔️ Created Types for Typescript
• ✔️ Using migrated dependencies on branch4.x

This is the most I can do. We cannot migrate the main project yet until 4.x is merged into master otherwise we will block new contributions. After release, I will complete the remaining part.

Update: Migration is done, waiting possible code reviews. #1374
