console.log() with fetched instance halts execution in async function

Question

I'm using Sequelize in an Express app, and I cannot figure out how to use console.log() in a async function. Whenever I want to printout a fetched instance from db, the console log halts the execution.

This is what I've tried (each example in separate tries):

updateUser: async (_, { id, ...args }, { User }) => {
  const user = await User.findById(3)
  // will later do some update to user here
  await Promise.resolve(console.log('user: ', user)) // halts the execution
  Promise.resolve(console.log('user: ', user)) // halts the execution
  await console.log('user: ', user) // halts the execution
  console.log('user: ', await user) // halts the execution
  console.log('user: ', user) // halts the execution
  console.log('only a string') // works!
  return user
},      

I've as well with 0 success tried the following:

const user = await User.findById(3).then(user => {
  console.log('user: ', user)
})

Answer 1

Assuming the User object returns a promise, try the following:

updateUser: async (_, { id, ...args }, { User }) => {
  const user = await User.findById(3)
  console.log('user: ', user)
  return user
}

Answer 2

console.log stops nothing, await does

This will stop execution until User has found something :

const user = await User.findById(3).then(user => {
  console.log('user: ', user)
})

As will this until aFunction has a response :

const user = await aFunction(anArg).then((do) => something);

What you want to do is :

var value; // have this somewhere or something similar
aFunction(anArg).then((res) => { value = res; })

Or in your case :

var savedUser; // have this somewhere or something similar
User.findById(3).then((user) => { savedUser = user; console.log('user: ', user); })

Answer 3

With using the await you are actually telling the javascript engine to stop till the promise is resolved.

Update code

updateUser: async (_, { id, ...args }, { User }) => {
  const user = await User.findById(3)
  // will later do some update to user here
  Promise.resolve(console.log('user: ', user)) // halts the execution
  console.log('user: ', user) // halts the execution
  console.log('only a string') // works!
  return user
},
