0:43 Setup for react native webrtc
1:46 Firebase setup
3:02 Creating simple components.
11:31 Webrtc Video call code
1. Creating the project:
Project uses expo bare workflow, The firebase native modules are only supported in expo bare workflow.
Build commands: (All the dependencies)
---------------------------------------------------------------------
expo init videoCall
cd videoCall
npm add @react-native-firebase/app @react-native-firebase/firestore @react-navigation/native @types/react-native-vector-icons react-native-webrtc react-native-vector-icons
---------------------------------------------------------------------
2. Setup for react native webrtc library:
We will be using react native webrtc for creating the video call app.

IOS: Please complete steps given in the repo. You will be able to follow along.
3. Firebase setup:
If you already don’t have a Firebase project, Please create as show. Otherwise you can use the existing project for this step. Copy the google-services.json file downloaded from firebase to Project-location/android/apps folder.
If the firestore database is not created, create it in test mode ( If you created in production mode, check the rules tab in firestore database)
**** MAKE SURE RULES ALLOW YOU TO ACCESS FIRESTORE ****
Code for Firebase setup:
-------------------------------------------------------------------------------
classpath'com.google.gms:google-services:4.3.4'
apply plugin: 'com.google.gms.google-services'
-------------------------------------------------------------------------------
As show in the video, Use the version that will be provided during the app creation.
• IOS setup:

Complete this steps, you will be able to follow along.
3.Creating simple components:
This step builds all the components required by the app.
• Buttons: Simple circle button component. Used to show call pick up and hang up.
• Video: Used to display local stream and remote stream. (camera views)
• Getting call: Used to display a caller image with option to pick up or hang up.
*All the dependency for this step is installed above.
4. Webrtc Video call code:
We will write the code for making call using webrtc in this step.
- We will exchange the ICE candidate from caller to callee through fireabse. ( we can use any real time update method for this step)
- There is no server involved for making this call. Caller and callee will directly communicate with each other
The flow: (Simple)
- We create an offer on click of call button.
- We send it to firestore. other party is registered for an event for offer.
- Once the app receives offer, it will display getting call component( I have used static image here ) with option to answer or decline. If you answer the call. We will create the answer object for the call and send it to caller through firestore.
- Once caller receives the answer, we will start the call.
Things used:
Visual studio, React native, expo, Firebase, react navigation.
