Added mongoKeys hook.

[eddyystop]

Wraps mongodb foreign keys in ObjectID

const { ObjectID | = require('mongodb');
const keyFieldNames = ['_id', 'authorId', 'postId'];

{ before: {
  find: mongoKeys(ObjectID, keyFieldNames)
} };

keys= a
from= { a: '111111111111', c: '000000000000' }

Published in v4.5.0

[eddyystop]

Its debateable whether _id should be included in the foreign keys list. the feathers-mongo adapter wraps _id already. On the other hand wrapping an already wrapped key should work properly.

If you are not using MongoDB, it is throwing errors when starting the app

[eddyystop]

Dare I suggest you not use it for non-MongoDB services?

{edit} Oops, I think I understand what you are saying. Fixing.

[eddyystop]

Fix published as v4.5.1. Sorry about that.
