restify(model: typeof Odin, options: Partial<restify.Options> = {}): Router;

This module's middleware parses url query string and executes a query on the given model accordingly and passes the query to you (since you might need to do some modifications on the query, too)

It also passes a counter which is exactly like query but without applying skip, limit, sort just because you might want to send a total count in your response as well

Lastly it passes the a decoded key in req.fro which is the parsed query string that is used in the middleware

Stringify all query params using qs default options

All the possible query modifiers are explained as a single modification but they all can be used together

/users?sort%5B0%5D=age

Filters

qs.stringify({
  filter: {
    field: "username",
    operator: "eq",
    value: "ardalanamini",
  }
})

qs.stringify({
  filter: {
    or: [
      {
        field: "username",
        operator: "eq",
        value: "ardalanamini",
      },
      {
        and: [
          {
            field: "age",
            operator: "gte",
            value: 18,
          },
          {
            field: "email",
            operator: "exists",
            value: true,
          },
        ],
      },
    ],
  },
})

filter can be a single filter object or and/or of Array<filter object>

possible operators:

lt | lte | eq | ne | gte | gt | exists | in | nin | bet | nbe | like | nlike

include

qs.stringify({
  include: [
    "relation1",
    "relation2.subRelation1.subRelation2",
  ]
})

sort

qs.stringify({
  sort: [
    "field1", // same as "+field1"
    "-field2",
    "+field3",
  ]
})

skip

qs.stringify({
  skip: 100,
})

limit

qs.stringify({
  limit: 10,
})
