2.Importing the SDK

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



Supported Platforms

Windows
macOS

Importing the SDK

Step 1. Install Node.js

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



1. Open the terminal window and run the following command to install Homebrew. If you have already installed it, skip this step.
$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
2. Run the following command to install Node.js (v10.0 or later).
$ brew install node

Step 2. Install Electron

Run the following command in the terminal 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
Note:
You can view the information of the latest version of the TRTC Electron SDK here.
2. In the project script, import 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
this.rtcCloud.getSDKVersion();
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
rtcCloud.getSDKVersion();

Step 4. Create an executable program

We recommend you use the build tool `electron-builder. You can run the following command to install it.
$ npm install electron-builder@latest --save-dev
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 5. Modify build configuration (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 according to your project.
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 built 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=', '');
break;
}
}
if (!['win32', 'darwin'].includes) target = os.platform();
return target;
})();
Note:
In the result returned by os.platform(), darwin means macOS, and win32 means Windows (64-bit or 32-bit).
2. 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'
// Build for different platforms
// rewritePath: './node_modules/trtc-electron-sdk/build/Release'
}
},
]
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.
For local building, native-ext-loader will load the TRTC SDK in ./node_modules/trtc-electron-sdk/build/Release. For details, see TRTCSimpleDemo configuration.
You also need to add the --target_platform parameter to the build script of package.json, which brings us to the next step.

Step 6. Modify package.json

The package.json file is in the root directory of the project and contains the necessary build information. Normally, to successfully build 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 follows:
"main": "main.electron.js",

// However, for projects created with the `create-react-app` scaffolding tool, `main` must be configured as follows:
"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"
}
Parameter
Description
main
The entry point file of Electron, which can be customized in most cases. However, if your project is created with create-react-app, the entry point file must be public/electron.js.
build.win.extraFiles
When building 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
The output path. In the sample above, the output file is saved to bin. You can modify it as needed.
build.scripts.build:mac
The script for building for macOS.
build.scripts.build:win
The script for building for Windows.
build.scripts.compile:mac
Creates a DMG file for macOS
build.scripts.compile:win64
Creates an EXE file for Windows
build.scripts.pack:mac
Calls build:mac to build the project and then `compile:mac` to generate a DMG file
build.scripts.pack:win64
Calls build:win to build the project and then `compile:win64` to generate an EXE file

Step 7. Run the build command

Build the project into a DMG file for macOS:
$ cd [Project directory]
$ npm run pack:mac
The build tool will generate an installation file named bin/your-app-name-0.1.0.dmg. Publish this file.
Build the project into an EXE file for Windows:
$ cd [Project directory]
$ npm run pack:win64
The build tool will generate an installation file named bin/your-app-name Setup 0.1.0.exe. Publish this file.
Note:
Currently, the TRTC Electron SDK does not support cross-platform building. This means you cannot build your project into an EXE file on macOS or a DMG file on Windows. We are working on this and may add support for it in the future.

FAQs

What firewall restrictions does TRTC 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 Firewall Restrictions.

What should I do if an error occurs when I install or build 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 building, please contact us.
