    This document describes how to quickly integrate the TRTC Electron SDK into your project.

    Supported Platforms

    • Windows
    • macOS

    Integrating TRTC Electron SDK

    Step 1: Install Node.js

    1. Download the latest version of Node.js installer Windows Installer (.msi) 64-bit.
    2. Open Node.js command prompt in the application list.

    Step 2. Install Electron

    Run the following command in the command prompt to install Electron. V4.0.0 or later is recommended.

    $ npm install electron@latest --save-dev

    Step 3. Install the TRTC Electron SDK

    1. Use the following nmp command in your Electron project to install the SDK.
      $ npm install trtc-electron-sdk@latest --save

    You can view the information of the latest version of the TRTC Electron SDK here.

    1. Import the module into the project script and use the module.
      const TRTCCloud = require('trtc-electron-sdk').default;
      // import TRTCCloud from 'trtc-electron-sdk';
      this.rtcCloud = new TRTCCloud();
      // Get the SDK version number

    Since v7.9.348, the TRTC Electron SDK has integrated trtc.d.ts for developers using TypeScript.

    import TRTCCloud from 'trtc-electron-sdk';
    const rtcCloud: TRTCCloud = new TRTCCloud();
    // Get the SDK version number

    Creating an Executable Program

    Step 1. Install a packaging tool

    1. We recommend that you use the packaging tool `electron-builder. You can run the following command to install it.

      $ npm install electron-builder@latest --save-dev
    2. In order to package the TRTC Electron SDK (trtc_electron_sdk.node) correctly, you must also run the following command to install native-ext-loader.

      $ npm install native-ext-loader@latest --save-dev

    Step 2. Modify webpack.config.js

    The webpack.config.js file contains the configuration information for project building. You can locate it in the following ways.

    • Normally, webpack.config.js is in the root directory of the project.
    • If you create your project with create-react-app, the configuration file will be node_modules/react-scripts/config/webpack.config.js.
    • If you create your project with vue-cli, webpack configuration will be stored in the configureWebpack property of vue.config.js.
    • If your project is customized, please locate webpack configuration by yourself.
    1. First, add the following code before module.exports to make webpack.config.js accept the --target_platform command line parameter so that your project can be packaged correctly for its target platform.
      const os = require('os');
      const targetPlatform = (function(){
       let target = os.platform();
       for (let i=0; i<process.argv.length; i++) {
           if (process.argv[i].includes('--target_platform=')) {
               target = process.argv[i].replace('--target_platform=', '');
       if (!['win32', 'darwin'].includes) target = os.platform();
       return target;

    In the result returned by os.platform(), darwin means macOS, and win32 means Windows (64-bit or 32-bit).

    1. Add the following configuration to the rules option. The targetPlatform variable ensures that rewritePath changes automatically according to the target platform.

      rules: [
           test: /\.node$/, 
           loader: 'native-ext-loader', 
           options: { 
               rewritePath: targetPlatform === 'win32' ? './resources' : '../Resources' 

      The above code achieves the following:

      • If you create an EXE file for Windows, native-ext-loader will load the TRTC SDK in [application root directory]/resources.
      • If you create a DMG file for macOS, native-ext-loader will load the TRTC SDK in [application directory]/Contents/Frameworsk/../Resources.

    You also need to add the --target_platform parameter to the build script of package.json. See step 3 for details.

    Step 3. Modify package.json

    The package.json file is in the root directory of the project and contains information needed for packaging. Normally, to successfully package your project, you need to modify the path in package.json as follows.

    1. Modify main.
      // In most cases, the name of the `main` file can be customized. For example, in TRTCSimpleDemo, `main` can be configured as:
      "main": "main.electron.js",

      // However, for projects created with the `create-react-app` scaffolding tool, `main` must be configured as:
      "main": "public/electron.js",
    2. Copy the following build configuration to your package.json file for electron-builder to read.
      "build": {
      "appId": "[Custom appId]",
      "directories": {
      "output": "./bin"
      "win": {
      "extraFiles": [
      "from": "node_modules/trtc-electron-sdk/build/Release/",
      "to": "./resources",
      "filter": ["**/*"]
      "mac": {
      "extraFiles": [
      "from": "node_modules/trtc-electron-sdk/build/Release/trtc_electron_sdk.node",
      "to": "./Resources"
    3. Add command scripts for building and packaging under scripts.
      The following command scripts are for projects created with create-react-app and vue-cli. They provide samples for projects created with other tools too.
      // Use this configuration for projects created with `create-react-app`.
      "scripts": {
      "build:mac": "react-scripts build --target_platform=darwin",
      "build:win": "react-scripts build --target_platform=win32",
      "compile:mac": "node_modules/.bin/electron-builder --mac",
      "compile:win64": "node_modules/.bin/electron-builder --win --x64",
      "pack:mac": "npm run build:mac && npm run compile:mac",
      "pack:win64": "npm run build:win && npm run compile:win64"

      // Use this configuration for projects created with `vue-cli`.
      "scripts": {
      "build:mac": "vue-cli-service build --target_platform=darwin",
      "build:win": "vue-cli-service build --target_platform=win32",
      "compile:mac": "node_modules/.bin/electron-builder --mac",
      "compile:win64": "node_modules/.bin/electron-builder --win --x64",
      "pack:mac": "npm run build:mac && npm run compile:mac",
      "pack:win64": "npm run build:win && npm run compile:win64"
      main Entry point file of Electron, which can be customized in most cases. However, if your project is created with create-react-app, the file must be public/electron.js.
      build.win.extraFiles When packaging for Windows, electron-builder will copy all files in the directory specified by from to bin/win-unpacked/resources (all in lowercase).
      build.mac.extraFiles When packaging for macOS, electron-builder will copy the trtc_electron_sdk.node file specified by from to bin/mac/your-app-name.app/Contents/Resources (capitalize the first letter of each word)
      build.directories.output Output path for packaging. In the sample above, the output file is saved to bin. You can modify it as needed.
      build.scripts.build:mac Script for building for macOS
      build.scripts.build:win Script for building for Windows
      build.scripts.compile:mac Compile into a DMG file for macOS
      build.scripts.compile:win64 Compile into an EXE file for Windows
      build.scripts.pack:mac Call build:mac to build the project and then `compile:mac` to package it into a DMG file
      build.scripts.pack:win64 Call build:win to build the project and then `compile:win64` to package it into an EXE file

    Step 4. Run the packaging command

    • Package the project into a DMG file for macOS:

      $ cd [Project directory]
      $ npm run pack:mac

      The packaging tool will generate an installation file named bin/your-app-name-0.1.0.dmg. Publish this file.

    • Package the project into an EXE file for Windows:

      $ cd [Project directory]
      $ npm run pack:win64

      The packaging tool will generate an installation file named bin/your-app-name Setup 0.1.0.exe. Publish this file.


    Currently, the TRTC Electron SDK does not support cross-platform packaging. This means you cannot package your project into an EXE file on macOS or a DMG file on Windows, but we are working on adding support for it in the future.


    1. What firewall restrictions does the SDK face?

    The SDK uses the UDP protocol for audio/video transmission and therefore cannot be used in office networks that block UDP. If you encounter such a problem, see How to Deal with Firewall Restrictions.

    2. What should I do if an error occurs when I install or package the TRTC Electron SDK?

    If an error occurs when you integrate the TRTC Electron SDK, for example, if installation times out or the trtc_electron_sdk.node file fails to load after packaging, please contact us for help.
