quave:resolvers

quave:resolvers is a Meteor package that receives a defintion and generates resolvers.

Why

We don't want to write the same resolvers all the time, for example, to list data, to get one specific record by id, to update data, etc. Then we have these common resolvers defined automatically.

We believe we are not reinventing the wheel in this package but what we are doing is like putting together the wheels in the vehicle :).

Installation

meteor add quave:resolvers

Usage

You will get automatically resolvers and methods in your collection.

resolvable

Methods:

• save(input): saves or update your data into a document.
• erase(_id): removes your data using the _id.

You can apply this resolvable composer in your collection using quave:collections or manually to add new methods to your collection.

1import { createCollection } from 'meteor/quave:collections';
2import { resolvable } from 'meteor/quave:resolvers';
3
4import { PlayerSchema, PlayerDefinition } from './PlayersDefinitions';
5
6export const PlayersCollection = createCollection({
7  name: PlayerDefinition.pluralNameCamelCase,
8  definition: PlayerDefinition,
9  schema: PlayerSchema,
10  composers: [resolvable],
11});

GraphQL

Resolvers and Schema (using Player as example but the names will be based in your definition):

type Query {
  player(_id: ID!): Player
  players: [Player]
}      

type Mutation {
  savePlayer(player: PlayerInput!): Player
  erasePlayer(_id: ID!): Player
}      

You create your resolvers using the definition and the collection together as you can see below.

1import { startGraphQLServer } from 'meteor/quave:graphql';
2
3import { createResolvers } from 'meteor/quave:resolvers';
4
5import { DateTimeResolver } from 'meteor/quave:custom-type-date-time/DateTimeResolver';
6import { DateTimeDefinition } from 'meteor/quave:custom-type-date-time/DateTimeDefinition';
7import { PlayerPositionDefinition } from '../imports/players/PlayerPositionEnum';
8import { PlayersCollection } from '../imports/players/PlayersCollection';
9import { PlayerDefinition } from '../imports/players/PlayersDefinitions';
10
11startGraphQLServer({
12  typeDefs: [
13    DateTimeDefinition,
14    PlayerPositionDefinition.toGraphQL(),
15    PlayerDefinition.toGraphQL(),
16  ],
17  resolvers: [
18    DateTimeResolver,
19    createResolvers({
20      definition: PlayerDefinition,
21      collection: PlayersCollection,
22    }),
23  ],
24});
