Add TypeScript declarations

[9at8]

@lorensr I'm not sure why npm install triggered a massive change in the lock file.

~/src/github.com/apollo-datasource-mongodb types
❯ npm --version
6.14.3

~/src/github.com/apollo-datasource-mongodb types
❯ node --version
v12.16.1

I have a project that I'm working on (it's private), and I'm using mongodb collections in that project. It works to the best of my knowledge.

Any feedback is appreciated! 😃

this is only sometimes defined—should it be model? ?

[9at8]

If we change this to model?, then in a project which uses mongoose, devs would have to do this.model?.someMethod or this.model && this.model.someMethod.

As seen on line 14, this is going to conditionally have type MongooseModel<T> (if the class is specialized with a mongoose collection) or never if the constructor is specialized with a mongo collection)

Maybe I should change line 14 to this:

  export type Model<T> = T extends Document ? MongooseModel<T> : undefined

[9at8]

After this change ^

this.model will have type:

• MongooseModel<T> if constructor is passed a MongooseModel<T>
• undefined if we're using a MongoCollection

What do you think?

[lorensr]

sounds more accurate than never? whatever you think best

Thanks! Released in 0.2.4
