Typescript Generic type error

[stretch0]

Trying to use MongoDataSource to extend my User dataSource class with typescript but seem to be getting the following error:

Generic type 'MongoDataSource<TData, TContext>' requires between 1 and 2 type arguments.ts(2707)

My User dataSrouce class is as so:

export default class Users extends MongoDataSource { }

How am I supposed to call MongoDataSource with 2 args when it's used to extend my own class?

Hey @stretch0 ! Have you tried something like the example in the readme? https://github.com/GraphQLGuide/apollo-datasource-mongodb#typescript

Let me know if you have any other questions! 😀

That has done the trick.

Thanks for your help 😄
