addMocksToSchema

addMocksToSchema<TResolvers>(__namedParameters): GraphQLSchema

Defined in: packages/mock/src/addMocksToSchema.ts:103

Given a schema and a MockStore, returns an executable schema that will use the provided MockStore to execute queries.

const schema = buildSchema(`
 type User {
   id: ID!
   name: String!
 }
 type Query {
   me: User!
 }
`)

const store = createMockStore({ schema });
const mockedSchema = addMocksToSchema({ schema, store });

If a resolvers parameter is passed, the query execution will use the provided resolvers if, one exists, instead of the default mock resolver.

const schema = buildSchema(`
  type User {
    id: ID!
    name: String!
  }
  type Query {
    me: User!
  }
  type Mutation {
    setMyName(newName: String!): User!
  }
`)

const store = createMockStore({ schema });
const mockedSchema = addMocksToSchema({
  schema,
  store,
  resolvers: {
    Mutation: {
      setMyName: (_, { newName }) => {
         const ref = store.get('Query', 'ROOT', 'viewer');
         store.set(ref, 'name', newName);
         return ref;
      }
    }
  }
 });

Query and Mutation type will use key 'ROOT'.
