Page

JSON API Pagination Plugin

[GET] http://example.com/posts?page[limit]=10&page[offset]=2 [GET] http://example.com/posts?page[size]=10&page[number]=2

Cursor pagination is not yet implemented.

You may need to calculate certain page data to generate pagination links. You can use page_data/3 that this module imports for you.

  query = build_query(User, conn, params)
  data = page_data(query, repo, params)

  links = build_links(data)
  meta = build_meta(data)
  users = Repo.all(query)

Filter

Use Inquisitor.JsonApi.Filter after Inquisitor

defmodule MyApp.PostController do
  use MyAp.Web, :controller
  use Inquisitor
  use Inquisitor.JsonApi.Filter

  ...

This plugin follows the spec for pagination with JSON API. All requests should conform to that URL schema for this plugin to work.

[GET] http://example.com/posts?filter[name]=Brian&filter[age]=99

By default Filter is no-op. You must define a custom build_filter_query/4 handler:

def build_filter_query(query, "name", name, _conn) do
  Ecto.Query.where(query, [r], r.name == ^name)
end
