Introduction

MediaSFU is a 2-page application consisting of a prejoin/welcome page and the main events room page. This guide will walk you through the basic usage of the module for setting up these pages.

Prebuilt Event Rooms

MediaSFU provides prebuilt event rooms for various purposes. These rooms are rendered as full pages and can be easily imported and used in your application. Here are the available prebuilt event rooms:

1. MediasfuGeneric: A generic event room suitable for various types of events.
2. MediasfuBroadcast: A room optimized for broadcasting events.
3. MediasfuWebinar: Specifically designed for hosting webinars.
4. MediasfuConference: Ideal for hosting conferences.
5. MediasfuChat: A room tailored for interactive chat sessions.

To use these prebuilt event rooms, simply import them into your application:

import { MediasfuGeneric, MediasfuBroadcast, MediasfuWebinar, MediasfuConference, MediasfuChat } from 'mediasfu-reactjs';

Simplest Usage

The simplest way to use MediaSFU is by directly rendering a prebuilt event room component, such as MediasfuGeneric:

import { MediasfuGeneric } from 'mediasfu-reactjs';

const App = () => {
  return (
    <MediasfuGeneric />
  );
}

export default App;

Programmatically Fetching Tokens

If you prefer to fetch the required tokens programmatically without visiting MediaSFU's website, you can use the PreJoinPage component and pass your credentials as props:

import { MediasfuGeneric, PreJoinPage } from 'mediasfu-reactjs';

const App = () => {
  const credentials = { apiUserName: "yourAPIUserName", apiKey: "yourAPIKey" };

  return (
    <MediasfuGeneric PrejoinPage={PreJoinPage} credentials={credentials} />
  );
}

export default App;

Preview of Welcome Page

Preview of Prejoin Page

Custom Welcome/Prejoin Page

Alternatively, you can design your own welcome/prejoin page. The core function of this page is to fetch user tokens from MediaSFU's API and establish a connection with the returned link if valid.

Parameters Passed to Custom Page

MediaSFU passes relevant parameters to the custom welcome/prejoin page:

let { showAlert, updateIsLoadingModalVisible, onWeb, connectSocket, socket, updateSocket, updateValidated,
     updateApiUserName, updateApiToken, updateLink, updateRoomName, updateMember, validated } = parameters;

Ensure that your custom page implements the following updates:

await updateSocket(socket);
await updateApiUserName(apiUserName);
await updateApiToken(apiToken);
await updateLink(link);
await updateRoomName(apiUserName);
await updateMember(userName);
await updateValidated(true);

See the following code for the PreJoinPage page logic:

import React, { useState } from 'react';
import Cookies from 'universal-cookie';

const cookies = new Cookies();
const MAX_ATTEMPTS = 10; // Maximum number of unsuccessful attempts before rate limiting
const RATE_LIMIT_DURATION = 3 * 60 * 60 * 1000; // 3 hours in milliseconds
const apiKey = 'yourAPIKEY'
const apiUserName = 'yourAPIUSERNAME'
const user_credentials = { apiUserName, apiKey };

async function joinRoomOnMediaSFU(payload, apiUserName, apiKey) {
    try {
      
        //check if apiUserName and apiKey are valid
        if (!apiUserName || !apiKey) {
            return { data: null, success: false };
        }

        //check if generic apiUserName and apiKey are used
        if (apiUserName === 'yourAPIUSERNAME' || apiKey === 'yourAPIKEY') {
            return { data: null, success: false };
        }

        //apiKey must be 64 characters long
        if (apiKey.length !== 64) {
            return { data: null, success: false };
        }

        if (apiUserName.length < 6) {
            return { data: null, success: false };
        }

        const response = await fetch('https://mediasfu.com/v1/rooms/', {

            },
            body: JSON.stringify(payload)
        });

        if (!response.ok) {
            throw new Error(`HTTP error! Status: ${response.status}`);
        }

        const data = await response.json();

        return { data, success: true };
    } catch (error) {

        return { data: null, success: false };
    }
}

async function createRoomOnMediaSFU(payload, apiUserName, apiKey) {
    try {

        //check if apiUserName and apiKey are valid
        if (!apiUserName || !apiKey) {
            return { data: null, success: false };
        }

        //check if generic apiUserName and apiKey are used
        if (apiUserName === 'yourAPIUSERNAME' || apiKey === 'yourAPIKEY') {
            return { data: null, success: false };
        }

        //apiKey must be 64 characters long
        if (apiKey.length !== 64) {
            return { data: null, success: false };
        }

        if (apiUserName.length < 6) {
            return { data: null, success: false };
        }


        const response = await fetch('https://mediasfu.com/v1/rooms/', {

            method: 'POST',
            headers: {
                'Content-Type': 'application/json',
                'Authorization': 'Bearer ' + apiUserName + ':' + apiKey,
            },
            body: JSON.stringify(payload)
        });

        if (!response.ok) {
            throw new Error(`HTTP error! Status: ${response.status}`);
        }

        const data = await response.json();

        return { data, success: true };
    } catch (error) {

        return { data: null, success: false };
    }

IP Blockage Warning And Local UI Development

Entering the event room without the correct credentials may result in IP blockage, as the page automatically attempts to connect with MediaSFU servers, which rate limit bad requests based on IP address.

If users attempt to enter the event room without valid credentials or tokens, it may lead to IP blockage due to MediaSFU servers' rate limiting mechanism. To avoid unintentional connections to MediaSFU servers during UI development, users can pass the useLocalUIMode parameter as true.

In this mode, the module will operate locally without making requests to MediaSFU servers. However, to render certain UI elements such as messages, participants, requests, etc., users may need to provide seed data. They can achieve this by importing random data generators and passing the generated data to the event room component.

Example for Broadcast Room

import { MediasfuBroadcast, generateRandomParticipants, generateRandomMessages } from 'mediasfu-reactjs';

function App() {
  const useSeed = true;
  let seedData = {};

  if (useSeed) {
    const memberName = 'Alice';
    const hostName = 'Fred';
    const participants_ = generateRandomParticipants(memberName, "", hostName, true);
    const messages_ = generateRandomMessages(participants_, memberName, "", hostName, true);

    seedData = {
      participants: participants_,
      messages: messages_,
      member: memberName,
      host: hostName,
    };
  }

  const useLocalUIMode = useSeed ? true : false;

  return (
    <MediasfuBroadcast useLocalUIMode={useLocalUIMode} useSeed={useSeed} seedData={useSeed ? seedData : {}} />
  );
}

export default App;

Example for Generic View

import { MediasfuGeneric, generateRandomParticipants, generateRandomMessages, generateRandomRequestList, generateRandomWaitingRoomList } from 'mediasfu-reactjs';

function App() {
  const useSeed = true;
  let seedData = {};
  const eventType = 'webinar'; // 'broadcast', 'chat', 'webinar', 'conference'

  if (useSeed) {
    const memberName = 'Prince';
    const hostName = 'Fred';
    const participants_ = generateRandomParticipants(memberName, "", hostName, eventType==="broadcast" || eventType==="chat" ? true : false);
    const messages_ = generateRandomMessages(participants_, memberName, "", hostName, eventType==="broadcast" || eventType==="chat" ? true : false);
    const requests_ = generateRandomRequestList(participants_, memberName, "", 3);
    const waitingList_ = generateRandomWaitingRoomList(participants_, memberName, "", 3);

    seedData = {
      participants: participants_,
      messages: messages_,
      requests: requests_,
      waitingList: waitingList_,
      member: memberName,
      host: hostName,
      eventType: eventType
    };
  }

  const useLocalUIMode = useSeed ? true : false;

  return (
    <MediasfuGeneric useLocalUIMode={useLocalUIMode} useSeed={useSeed} seedData={useSeed ? seedData : {}} />
  );
}

export default App;

In the provided examples, users can set useLocalUIMode to true during UI development to prevent unwanted connections to MediaSFU servers. Additionally, they can generate seed data for rendering UI components locally by using random data generators provided by the module.

Local UI Development in MediaSFU ReactJS Module

During local UI development, the MediaSFU view is designed to be responsive to changes in screen size and orientation, adapting its layout accordingly. However, since UI changes are typically linked to communication with servers, developing the UI locally might result in less responsiveness due to the lack of real-time data updates. To mitigate this, users can force trigger changes in the UI by rotating the device, resizing the window, or simulating server responses by clicking on buttons within the page.

While developing locally, users may encounter occasional error warnings as the UI attempts to communicate with the server. These warnings can be safely ignored, as they are simply indicative of unsuccessful server requests in the local development environment.

If users experience responsiveness issues, whether during local development or in production, they can optimize their HTML configuration to ensure proper scaling and viewport settings. By adding the following meta tag to the HTML <head> section, users can specify viewport settings for optimal display:

<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />

Intermediate Usage Guide

Expands on the basic usage, covering more advanced features and scenarios.

Intermediate Usage Guide

In the Intermediate Usage Guide, we'll explore the core components and functionalities of the MediaSFU ReactJS module, focusing on media display, controls, and modal interactions.

Core Components Overview

The main items displayed on an event page are media components (such as video, audio, and blank cards) and control components (for pagination, navigation, etc.).

Media Display Components:

| Component Name | Description | |--------------------------|-------------------------------------------------------------------------------------------------| | Main Aspect Component| Serves as a container for the primary aspect of the user interface, typically containing the main content or focus of the application. | | Main Screen Component| Responsible for rendering the main screen layout of the application, providing the foundation for displaying various elements and content. | | Main Grid Component | Crucial part of the user interface, organizing and displaying primary content or elements in a grid layout format. | | Sub Aspect Component | Acts as a secondary container within the user interface, often housing additional elements or controls related to the main aspect. | | Main Container Component | Primary container for the application's content, encapsulating all major components and providing structural organization. | | Other Grid Component | Complements the Main Grid Component by offering additional grid layouts, typically used for displaying secondary or auxiliary content. |

Control Components:

| Component Name | Description | |-------------------------------|-------------------------------------------------------------------------------------------------| | Control Buttons Component | Comprises a set of buttons or controls used for navigating, interacting, or managing various aspects of the application's functionality. | | Control Buttons Alt Component | Provides alternative button configurations or styles for controlling different aspects of the application. | | Control Buttons Component Touch | Specialized component designed for touch-enabled devices, offering floating buttons or controls for intuitive interaction with the application's features. |

            icon: faPhone,
            active: endCallActive,
            onPress: () => console.log('End Call pressed'), //not in use
            activeColor: 'transparent',
            inActiveColor: 'transparent',
            backgroundColor: 'transparent',
            show: false,
        }
    ];

This sample code defines arrays recordButtons and controlBroadcastButtons, each containing configuration objects for different control buttons. These configurations include properties such as icon, active state, onPress function, activeColor, inActiveColor, and show flag to control the visibility of each button.

You can customize these configurations according to your requirements, adding, removing, or modifying buttons as needed. Additionally, you can refer to the relevant component files (ControlButtonsAltComponent.js and ControlButtonsComponentTouch.js) for more details on how to add custom buttons.

Room Socket Events

In the context of a room's real-time communication, various events occur, such as user actions, room management updates, media controls, and meeting status changes. To effectively handle these events and synchronize the application's state with the server, specific functions are provided. These functions act as listeners for socket events, allowing the application to react accordingly.

Provided Socket Event Handling Functions:

| Function | Explanation | |-------------------------------|---------------------------------------------------------------------------------------------------------| | userWaiting | Triggered when a user is waiting. | | personJoined | Triggered when a person joins the room. | | allWaitingRoomMembers | Triggered when information about all waiting room members is received. | | roomRecordParams | Triggered when room recording parameters are received. | | banParticipant | Triggered when a participant is banned. | | updatedCoHost | Triggered when the co-host information is updated. | | participantRequested | Triggered when a participant requests access. | | screenProducerId | Triggered when the screen producer ID is received. | | updateMediaSettings | Triggered when media settings are updated. | | producerMediaPaused | Triggered when producer media is paused. | | producerMediaResumed | Triggered when producer media is resumed. | | producerMediaClosed | Triggered when producer media is closed. | | controlMediaHost | Triggered when media control is hosted. | | meetingEnded | Triggered when the meeting ends. | | disconnectUserSelf | Triggered when a user disconnects. | | receiveMessage | Triggered when a message is received. | | meetingTimeRemaining | Triggered when meeting time remaining is received. | | meetingStillThere | Triggered when the meeting is still active. | | startRecords | Triggered when recording starts. | | reInitiateRecording | Triggered when recording needs to be re-initiated. | | getDomains | Triggered when domains are received. | | updateConsumingDomains | Triggered when consuming domains are updated. | | RecordingNotice | Triggered when a recording notice is received. | | timeLeftRecording | Triggered when time left for recording is received. | | stoppedRecording | Triggered when recording stops. | | hostRequestResponse | Triggered when the host request response is received. | | allMembers | Triggered when information about all members is received. | | allMembersRest | Triggered when information about all members is received (rest of the members). | | disconnect | Triggered when a disconnect event occurs. |

Sample Usage:

// Example usage of provided socket event handling functions

import { participantRequested,screenProducerId } from 'mediasfu-reactjs'

socket.current.on('participantRequested', async ({ userRequest }) => {
    await participantRequested({
        userRequest,
        parameters: { ...getAllParams(), ...mediaSFUFunctions() },
    });
});

socket.current.on('screenProducerId', async ({ producerId }) => {
    await screenProducerId({
        producerId,
        parameters: { ...getAllParams(), ...mediaSFUFunctions() },
    });
});

These functions enable seamless interaction with the server and ensure that the application stays synchronized with the real-time events occurring within the room.

Troubleshooting

1. Optimizing HTML Configuration: If users experience responsiveness issues, whether during local development or in production, they can optimize their HTML configuration to ensure proper scaling and viewport settings. By adding the following meta tag to the HTML <head> section, users can specify viewport settings for optimal display:

   <meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />

2. Issues with Starting User Media (Audio/Video): If users encounter issues with starting user media (audio/video), they should try running in HTTPS mode. To enable HTTPS mode, users can modify their start script in the package.json file as follows:

   "start": "set HTTPS=true && react-scripts start",

3. Interactive Testing with MediaSFU's Frontend: Users can interactively join MediaSFU's frontend in the same room to analyze if various events or media transmissions are happening as expected. For example, adding a user there to check changes made by the host and vice versa.

These troubleshooting steps should help users address common issues and optimize their experience with MediaSFU. If the issues persist or additional assistance is needed, users can refer to the documentation or reach out to the support team for further assistance.
