Returns: Promise<Array<Attributes>>

Param	Type	Description

About

The resolveArrayByClass combines resolveModelsByClass and getArrayData into one function for easier use of the API.

In a nut shell:

  resolveModelsByClass(ClassName)
    === getArrayData(resolveModelsByClass(ClassName));

For more detailed documentation see resolveModelsByClass and getArrayData.

Examples

Consider the following GraphQL Schema Type for queryType:

var queryType = new GraphQLObjectType({
  name: 'Query',
  fields: () => ({
    people: {
      description: 'People',
      type: personConnection,
      args: connectionArgs,
      resolve: (root, args) =>
        connectionFromPromisedArray(resolveArrayByClass(Person), args)
    },
    peopleWithMethods: {
      description: 'People with methods',
      type: personConnection,
      args: connectionArgs,
      resolve: (root, args) =>
        connectionFromPromisedArray(resolveArrayByClass(Person, true), args)
    },
    articles: {
      description: 'Articles',
      type: articleConnection,
      args: connectionArgs,
      resolve: (root, args) =>
        connectionFromPromisedArray(resolveArrayByClass(Article), args)
    },
    node: nodeField
  })
});

From there, we are able to pass graphql-relay queries like so:

{
  peopleWithMethods(first: 2) {
    pageInfo {
      startCursor
      hasNextPage
    }
    edges {
      cursor
      node {
        id
        givenName
        familyName
        address
      }
    }
  }
}

{
  articles(first: 2) {
    pageInfo {
      startCursor
      hasNextPage
    }
    edges {
      cursor
      node {
        id
        givenName
        familyName
        address
      }
    }
  }
}
