将Firebase方法转换为异步等待

Question

I have this firebase method that creates a firebase user using a email and password

async register(name, email, password,type) {
    let id;
    const createUser = this.functions.httpsCallable('createUser');

    return await this.auth.createUserWithEmailAndPassword({email,password })
      .then((newUser)=>{
        id = newUser.user.uid;
        newUser.user.updateProfile({
          displayName: name
        })
      })
      .then(()=>{
        createUser({
          id:id,
          name:name,
          email:email,
          type:type
        })
      })
  }

It also adds the user to a firestore collection using a cloud function that takes the user details and user type.

I have 3 Promises (

1. createUserWithEmail...()
2. updateUserProfile()1
3. createUser()

) which Are dependent on each other.. How do I use them in one function?

NB : Couldn't use the functions.auth.user().onCreate() method because of the user type field

How do I write this method without using the .then() ? Some users aren't appearing in the database

Answer 1

to remove .then simply use await "better"

async register(name, email, password,type) {
    let id;
    const createUser = this.functions.httpsCallable('createUser');

    const newUser = await this.auth.createUserWithEmailAndPassword({email,password });
    id = newUser.user.uid;
    // assuming the next two functions are asynchrnous AND return a promise
    // if not, just remove await
    await newUser.user.updateProfile({displayName: name});
    await createUser({
        id:id,
        name:name,
        email:email,
        type:type
    });
}
