Thanks for opening this issue!

• 🎉 We are excited about your ideas for improvement!

@mtrezza just realized I can’t edit the OP (original post). I would like to put my name down to claim some files in case @danielbm @sadortun or other developers want to work on them to prevent conflicts

I'd say just post a comment with the sub-list you're working on and I'll update the main list from time to time.

Alright, once the PRs are merged, I'll go ahead and cross the items off the list. Other than that, as always, a contributor is encouraged to read the thread to know whether someone is already working an the issue - or parts of it.

I also suggest to open a PR early while work is in progress, which allows others to have insight into the progress. To prevent blocking issues, as long as there is no PR (or the PR is stale) we would always welcome and suggest to others to start working on it if they asked.

quick question, is this npm package setup to allow using the typescript definitions defined in the parse.ts file? I'd like to remove @types/parse as it's outdated, but removing it causes typescript compile issues now.

Could not find a declaration file for module 'parse/node'. '.../node_modules/parse/node.js' implicitly has an 'any' type.

Try npm i --save-dev @types/parse if it exists or add a new declaration (.d.ts) file containing declare module 'parse/node';ts(7016)

Thanks for your help.

@mtrezza I've been trying to tackle this here https://github.com/swittk/Parse-SDK-JS/tree/typescript
What do you think? If this seems OK I plan to finish more of it soon.

There are a few places where I'm not sure though,

• ParseGeoPoint static current() is supposed to return current GeoPoint, but it seems like the return result is wrapped in a callback
• ParseObject has a couple of places where this.constructor is used, and Typescript doesn't really like this pattern, so I had to cast any at those places.
• CoreManager.ts has a bunch of managers which appear to have either been defined with vague return values or incorrect function names, I've since corrected a few of them, but it's still not finished. Will look at the tests and DefaultManager implementation of each one to implement the correct types.

@swittk could you please open a PR for review?

• refactor: Remove Flow Type #2145

All files have been converted to TypeScript. I'm not a TS developer and I don't have a TS project to test with.

Here are the next steps

• Remove to @types/parse on DefinitelyTyped
• Add "types": "./types/index.d.ts" to package.json
• Add stricter typing (we use any everywhere)
• Update CONTRIBUTING.md with building types and linting
• Add ./types to files in package.json?
• Use namespaces and interfaces to match @types/parse/index.d.ts

@parse-community/js-sdk Can this issue be closed?

This issue is half done. I left instructions in my last comment on the next steps to close it if anybody is interested.
