how to create different users using reactjs and firebase

Question

I am trying to create a web application with ReactJs and firebase. I want to know how to create three users with different roles like doctor, patient, pharmacist.

My Signup.js file

    if (pass.value != cpass.value) {
  alert("Password dont match")
}
else {
  try {
    var e = email.value
    const ref = db.collection("doctor")
    setLoading(true)
    await app
      .auth()
      .createUserWithEmailAndPassword(email.value, pass.value);
    ref.doc(e).set({
      "name": uname.value,
      "dob": dob.value,
      "email": email.value,
      "phno": phno.value,
      "regno": regno.value,
      "regyear": regyear.value,
      "gender": gender.value,
      "addr": addr.value,
      "pincode": pin.value,
      "city": city.value,
      "state": state.value,
      "bloodtype": bloodtype.value,
      "speciality": speciality.value,


    }).then(() => {
      console.log("Document successfully written!");
    });
    db.collection("users").doc(email.value).set({
      "email":email.value,
      "userType":"doctor"
    })

Answer 1

You have set the collection to doctors in the following code snippet:

const ref = db.collection("doctor")

If you want to add a different user to a different firebase collection you just need to replace the collection name:

const ref = db.collection("patient")
