GraphQL Sorting

The implementation of a GraphQL Service requires a certain structure to follow for Aurelia-Slickgrid to work correctly (it will fail if your GraphQL Schema is any different than what is shown below).

Implementation

For the implementation in your code, refer to the GraphQL Service section.

orderBy

The sorting uses orderBy as per this GitHub Suggestion of a Facebook employee. The query will have a orderBy argument with an array of filter properties:

• orderBy: array of sorting object(s) (see below)
  • field: field name to sort
  • direction: a GraphQL enum (server side) that can have 1 of these choices:
    • ASC, DESC

Note: the orderBy order is following the order of how the filter objects were entered in the array.

For example

  users (first: 20, offset: 10, orderBy: [{field: lastName, direction: ASC}, {field: firstName, direction: DESC}]) {
    totalCount
    pageInfo {
      hasNextPage
    }
    nodes {
      name
      firstName
      lastName
      gender
    }
  }
