For example, if i need to send an email after a user has signed up how can i do i see a pre-save hook but didn't find any for the post.

if you use graphql-compose-mongoose

You may get existing Resolver and wrap its resolve method.

UserTC.wrapResolverResolve('createOne', (next) => async (rp) => {
  const doc = await next(rp);
  // any logic after saving document in DB
  return doc;
});

if you create schema in any another way

Just get fieldConfig and wrap its resolve method manually

const fc = schemaComposer.Mutation.getField('create');
const prevResolve = fc.resolve;
fc.resolve = async (source, args, context, info) => {
  const record = await prevResolve(source, args, context, info);
  // any logic after saving
  return record;
};
