Getting Started

This section will guide users through the initial setup and installation of the npm module.

Note: this is specifically for React-Native-Expo. If you are integrating into a React Native CLI app, the best option is to use the core mediasfu-reactnative package, which you can find on npm at mediasfu-reactnative.

Documentation Reference

For comprehensive documentation on the available methods, components, and functions, please visit mediasfu.com. This resource provides detailed information for this guide and additional documentation.

Installation

Instructions on how to install the module using npm.

1. Add the Package to Your Project

npm install mediasfu-reactnative-expo

2. Obtain an API Key from MediaSFU

You can get your API key by signing up or logging into your account at mediasfu.com.

3. Configure Your Project

Before proceeding, ensure that your project is properly configured to work with mediasfu-reactnative-expo. Follow the steps below to set up the necessary configuration files.

a. Update `app.json`

Ensure that your app.json does not have the output field set to 'static' in the web configuration. Remove or clear this field to prevent build issues.

{
  "expo": {
    // ... other configurations
    "web": {
      // Remove or ensure the output field is not set to 'static'
      // "output": "static" // This line should be removed or cleared
    }
  }
}

b. Configure `babel.config.js`

Your babel.config.js should include the necessary presets and plugins for Expo and React Native Reanimated. Here is an example configuration:

module.exports = function (api) {
  api.cache(true);
  return {
    presets: ['babel-preset-expo'],
    plugins: [
      'react-native-reanimated/plugin',
      '@babel/plugin-transform-block-scoping'
    ],
  };
};

c. Configure `metro.config.js`

Ensure your metro.config.js file includes the correct settings for Metro bundler:

const { getDefaultConfig } = require('expo/metro-config');
const path = require('path');

const config = getDefaultConfig(__dirname);
config.resolver.nodeModulesPaths = [path.resolve(__dirname, 'node_modules')];

module.exports = config;

4. Complete the Setup

After completing the above steps, you can proceed to set up and run your project.

Start the Development Server:
```
npx expo start
```
Create a Development Build:
Since react-native-webrtc does not run on Expo Go, you will need to create a development build to test WebRTC functionalities on an actual device. Follow the Expo Development Builds documentation for guidance on creating a development build.

Documentation Reference

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:

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

Users can easily pick an interface and render it in their app.

If no API credentials are provided, a default home page will be displayed where users can scan or manually enter the event details.

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

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

Simplest Usage

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

import { MediasfuGeneric } from 'mediasfu-reactnative-expo';

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-reactnative-expo';

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, connectSocket, updateSocket, updateValidated,
     updateApiUserName, updateApiToken, updateLink, updateRoomName, updateMember } = parameters;

Ensure that your custom page implements the following updates:

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

See the following code for the PreJoinPage page logic:

  TextInput,
  Pressable,

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-reactnative-expo';

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 specific Mediasfu view components
// Import the PreJoinPage component for the Pre-Join Page use case
import { MediasfuGeneric,
    MediasfuBroadcast, MediasfuChat, MediasfuWebinar, MediasfuConference, PreJoinPage
 } from 'mediasfu-reactnative-expo'


// Import methods for generating random participants, messages, requests, and waiting room lists if using seed data
import { generateRandomParticipants, generateRandomMessages, generateRandomRequestList, generateRandomWaitingRoomList,
} from 'mediasfu-reactnative-expo';

/**
 * The main application component for MediaSFU.
 *
 * This component initializes the necessary credentials and configuration for the MediaSFU application,
 * including options for using seed data for generating random participants and messages.
 *
 * @returns {JSX.Element} The rendered Mediasfu component with the specified props.
 *
 * @remarks
 * - The `credentials` object contains the API username and API key for the Mediasfu account.
 * - The `useSeed` flag determines whether to use seed data for generating random participants and messages.
 * - The `eventType` variable indicates the type of UI display (e.g., 'broadcast', 'chat', 'webinar', 'conference').
 * - If `useSeed` is true, random participants, messages, requests, and waiting lists are generated and assigned to `seedData`.
 * - The `useLocalUIMode` flag is set to true if `useSeed` is true, preventing requests to the Mediasfu servers during UI development.
 *
 * @component
 * @example
 * // Example usage of the App component
 * <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 React Native (Expo) 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.

export default BroadcastScreen;

This sample code demonstrates the import and usage of various components and features for a Broadcast screen, including rendering different UI components based on the validation state, handling socket connections, displaying video streams, controlling recording, and managing component sizes.

Here's a sample usage of the control button components as used above:

      const recordButton = [
      // recording button (to launch recording modal)
      // Replace or remove any of the buttons as you wish
      {
        icon: "record-vinyl",
        text: "Record",
        onPress: () => {
          // Action for the Record button
          launchRecording({
            updateIsRecordingModalVisible: updateIsRecordingModalVisible,
            isRecordingModalVisible: isRecordingModalVisible,
            showAlert: showAlert,
