Rewrite in typescript about apollo-errors

[lakhansamani]

@thebigredgeek Is there any repo or branch where this work is started?

[thebigredgeek]

Not yet, nope! But I am looking for help with it if you wanna get started?

[lakhansamani]

Sure, would love to do that

[thebigredgeek]

Awesome! I look forward to your PR :D

[lakhansamani]

Hey @thebigredgeek I have tried making typescript version, you can check here https://github.com/lakhansamani/apollo-errors/tree/typescript

Please share your feedback on this and on how we want to build and publish it

[thebigredgeek]

@lakhansamani it looks good so far! Are we able to get the existing tests passing?

Also, it might be a good idea to add types the createError config property etc. Basically anything that is in interface between components and to the outside world.

We also need to create a PR at definitively-typed

[lakhansamani]

@thebigredgeek test cases are passing so far

Can you explain how you want to add types, that part was not clear

[thebigredgeek]

Right, so there is an interface for the ApolloError constructor as well as the createError function. We should have a typed interface for these, and create an entry for DefinitelyTyped so that people can install the type definitions
