Profile

Profile object is used to store data associated with a user. Using profile is in no way required, and will only be enabled if the userProfile config option is provided.

Basic

It is common to store the list of user profiles under a collection called "users" or "profiles". For this example we will use "users".

Include the userProfile parameter in config passed to react-redux-firebase:

const config = {
  userProfile: 'users', // where profiles are stored in database
}

Get Profile From State

Using useSelector Hook

Then later connect (from react-redux) to redux state with:

import { useSelector } from 'react-redux'

function SomeComponent() {
  const profile = useSelector(state => state.firebase.profile)
  return <div>{JSON.stringify(profile, null, 2)}</div>
}

function SomeComponent() {
  const profile = useSelector(({ firebase: { profile } }) => profile)
  return <div>{JSON.stringify(profile, null, 2)}</div>
}

Using connect HOC

Then later connect (from react-redux) to redux state with:

import { connect } from 'react-redux'

// grab profile from redux with connect
connect(
  (state) => {
    return {
      profile: state.firebase.profile // profile passed as props.profile
    }
  }
)(SomeComponent) // pass component to be wrapped

// or with some shorthand:
connect(({ firebase: { profile } }) => ({ profile }))(SomeComponent)

Profile in Firestore

To use Firestore for storing profile data instead of Real Time Database, the basic example can be followed exactly with the following config.

const config = {
  userProfile: 'users', // where profiles are stored in database
  useFirestoreForProfile: true // use Firestore for profile instead of RTDB
}

Update Profile

The current users profile can be updated by using the updateProfile method:

import React from 'react'
import PropTypes from 'prop-types'
import { compose } from 'redux'
import { useSelector } from 'react-redux'
import { useFirebase, isLoaded } from 'react-redux-firebase'

export default function UpdateProfilePage() {
  const firebase = useFirebase()
  const profile = useSelector(state => state.firebase.profile)

  function updateUserProfile() {
    return firebase.updateProfile({ role: 'admin' })
  }

  return (
    <div>
      <h2>Update User Profile</h2>
      <span>
        Click the button to update profile to include role parameter
      </span>
      <button onClick={updateUserProfile}>
        Add Role To User
      </button>
      <div>
        {
          isLoaded(profile)
            ? JSON.stringify(profile, null, 2)
            : 'Loading...'
        }
      </div>
    </div>
  )
}

Change How Profiles Are Stored

The way user profiles are written to the database can be modified by passing the profileFactory parameter .

// within your createStore.js or store.js file include the following config
const config = {
  userProfile: 'users', // where profiles are stored in database
  profileFactory: (userData, profileData, firebase) => { // how profiles are stored in database
    const { user } = userData
    return {
      email: user.email
    }
  }
}

This also works with profiles stored on Firestore if using the useFirestoreForProfile option

List Online Users

Populate Parameters

If profile object contains an key or a list of keys as parameters, you can populate those parameters with the matching value from another location on firebase.

List

profile.contacts contains a list of user UIDs that should be populated from the users list like so:

{
  displayName: 'Rick Sanchez',
  email: 'rick@rickandmorty.com',
  contacts: [
    'QvXyh688YNV29QuhCTXeOXnHt282',
    'T8Wh9CMHIxT1f9mA5oEETNrOOlt1'
  ]
}

Setting config like this:

const config = {
  userProfile: 'users', // where profiles are stored in database
  profileParamsToPopulate: [
    'contacts:users'
  ]
}

Results in profile with populated contacts parameter:

{
  displayName: 'Rick Sanchez',
  email: 'rick@sanchez.com',
  contacts: [
    {
      email: 'morty@ohboyrick.com',
      displayName: 'Morty Smith'
    },
     {
      email: 'bird@person.com',
      displayName: 'Bird Person'
    }
  ]
}
