Feathers.js mongoose querying

Question

I'm very new to feathers.js, how would you accomplish querying for an object?

{
   ...,
   obj: {
      foo: 1,
      bar: 1
   },
   ...
}

The following seems to not work

/some-doc?obj['foo']['$eq']=1

Also, how would you tackle a query like checking a size of array

/some-doc?someArray['length']['$gt']=0

I've been trying to send param like

checkArray=true

Process it at before:find but no luck. Is this the right approach?

Thank you,

In general, most queries supported by Mongoose and MongoDB will work for your Feathers service. MongoDB queries on nested fields using the dot notation so it would be:

/some-doc?obj.foo=1

Length queries can be done with the $size operator. To check if an array has a certain length, you can use the dot notation to see if the entry at the index exists (see this answer):

/some-doc?someArray.1[$exists]=true
