Simple registration resolvers

I've been struggling for a minute trying to write a custom resolver for checking if a user exists by email and logically creating or logging in a user.

Im really shocked I can't find one functional example of this based on GRAND
I can understand if I'm missing the point entirely and need to separate these concerns into separate queries/mutations but then I'm not really sure what the flow is. Any examples or obvious uses? Is there an example of server side utility queries? can I import autogenerated resolvers here?

const resolvers = {
  Mutation: {
    Register: async (_, { email, password }) => {
      const hashedPassword = await bcrypt.hash(password, 10);
      const emailExists = await /** SOME WAY TO FETCH 
           BOOLEAN FROM-Query ---> */ userByEmail({ email });
        return /** SOME WAY TO 
          TRIGGER MUTATION ---> */ createUser({
        variables: {
          email: email,
          uid: hashedPassword,
    Login: async (_, { email, password }, { res }) => {
      const user = await /** ALL THE EXAMPLES I SEE  ARE 
         CACHE AS DATASTORE ----> */ User.findOne({ where: { email } });
      if (!user) {
        return null;

      const valid = await, user.password);
      if (!valid) {
        return null;

      const r = sign({ userId:, count: user.count }, process.env.R, {
        expiresIn: '7d',
      const a = sign({ userId: }, process.env.A, {
        expiresIn: '15min',

      res.cookie('r', r);
      res.cookie('a', a);

      return user;

const schema = makeAugmentedSchema({

The GRANDstack and it's drivers auto create your resolvers for you. So you don't need to do that unless you want a lot of custom behavior or need something different. In which case there are ways to exclude the auto generated resovlers completely.
