Start or Join Meeting - React Native

After the successful installation of VideoSDK, the next step is to integrate VideoSDK features with your webApp/MobileApp.

To Communicate with other participant's audio or video call, you will need to join the meeting.

This guide will provide an overview of how to configure, initialize and join a VideoSDK meeting.

1. Configuration

To configure a meeting, you will need generated token and meetingId, we had discussed in Server Setup. This code snippet calls API from local server

Scenario 1 - Suppose you don't have any meetingId, you can simply generate meetingId by invoking create-meeting API.

Scenario 2 - Suppose you have meetingId, now you don't have to call create-meeting API to generate meetingId, instead you can call validate-meeting API to validate meetingId.

Token generation API is necessary for both scenario.

const getToken = async () => {
  try {
    const response = await fetch(`${LOCAL_SERVER_URL}/get-token`, {
      method: "GET",
      headers: {
        Accept: "application/json",
        "Content-Type": "application/json",
      },
    });
    const { token } = await response.json();
    return token;
  } catch (e) {
    console.log(e);
  }
};

const getMeetingId = async (token) => {
  try {
    const VIDEOSDK_API_ENDPOINT = `${LOCAL_SERVER_URL}/create-meeting`;
    const options = {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify({ token }),
    };
    const response = await fetch(VIDEOSDK_API_ENDPOINT, options)
      .then(async (result) => {
        const { meetingId } = await result.json();
        return meetingId;
      })
      .catch((error) => console.log("error", error));
    return response;
  } catch (e) {
    console.log(e);
  }
};

/** This API is for validate the meeting id  */
/** Not require to call this API after create meeting API  */
const validateMeeting = async (token, meetingId) => {
  try {
    const VIDEOSDK_API_ENDPOINT = `${LOCAL_SERVER_URL}/validate-meeting/${meetingId}`;
    const options = {
      method: "POST",
      headers: {
        "Content-Type": "application/json",
      },
      body: JSON.stringify({ token }),
    };
    const response = await fetch(VIDEOSDK_API_ENDPOINT, options)
      .then(async (result) => {
        const { meetingId } = await result.json();
        return meetingId;
      })
      .catch((error) => console.log("error", error));
    return response;
  } catch (e) {
    console.log(e);
  }
};

const access_token = await getToken();
const meetingId = await getMeetingId(access_token);
const validatedMeetingId = await validateMeeting(token, "provided-meeting-id");

2. Initialization

After configuration, you will have to Initialize

meeting by providing name, meetingId, micEnabled, webcamEnabled & maxResolution.

NOTE : For React & React native developer, you have

to be familiar with hooks concept. You can understand hooks concept on React Hooks.

import { MeetingProvider, useMeeting } from "@videosdk.live/react-native-sdk";

const App = () => {
  // Init Meeting Provider
  return (
    <MeetingProvider
      config={{
        meetingId: "<Id-on-meeting>",
        name: "<Name-of-participant>",
        participantId:'Id-of-participant' // optional,  default: SDK will generate
        micEnabled: "<Flag-to-enable-mic>",
        webcamEnabled: "<Flag-to-enable-webcam>",
        maxResolution: "<Maximum-resolution>",
        notification: {
          title: "<Notification-Title>",
          message: "<Notification-Message>",
        },
      }}
      token={"<Authentication-token>"}
    >
      <MeetingView>...</MeetingView>
    </MeetingProvider>
  );
};

const MeetingView = () => {
  // Get Meeting object using useMeeting hook
  const meeting = useMeeting();

  return <>...</>;
};

Use hooks API

Our React JS SDK provides two important hooks API:

• useMeeting : Responsible to handle meeting environment.
• useParticipant : Responsible to handle Participant

Also, React Provider and Consumer to listen changes in meeting environment.

• MeetingProvider : Meeting Provider is Context.Provider that allows consuming components to subscribe to meeting changes

3. Join

After configuration & initialization, the third step is to call join() to join a meeting.

After joining, you will be able to Manage Participant in a meeting.

import { useMeeting } from "@videosdk.live/react-native-sdk";

const MeetingView = () => {
  const { join } = useMeeting();

  const onPress = () => {
    // Joining Meeting
    join();
  };

  return <>...</>;
};

Events

Following callbacks are received when a participant is successfully joined.

• Local Participant will receive a onMeetingJoined event, when successfully joined.
• Remote Participant will receive a onParticipantJoined event with the newly joined Participant object from the event callback.

function onMeetingJoined() {
  console.log("onMeetingJoined");
}

function onParticipantJoined(participant) {
  console.log(" onParticipantJoined", participant);
}

const {
  meetingId
  ...
} = useMeeting({
  onMeetingJoined,
  onParticipantJoined,
  ...
});
