• Project Structure 📌

  • native-app/ Contains the source code for the Android and iOS clients. The directory contains the JavaScript code in React Native and the Android build for the same.
  • intralan-web/ Contains the web client written in React and the corresponding desktop client ported via electron.

• Features 📃

  • Phone Calls End to end encrypted calls that do not require internet connection and are fast and reliable. Say goodbye to dropped connections. :)
  • Chats Safely send and recieve messages without sending them to places that you dont intend to. No database and hence all your data is in your hands. 🔒
  • File Sharing Send any files of any size at fast speeds between any devices. Next time you have notes to send, NetCon has got you covered. 📁

    Prerequistes

    • Android SDK v28 installed
    • ndk bundle Download from here
    • Extract and copy the downloaded ndk files to the /home/user/Android/Sdk/ndk folder

    Steps

    • Start by cloning the repository.

    • Since React Native does not run in a nodejs environment, an external package for using nodejs and hence the HTTP server for broadcasting is used by the application.

    • Once cloned, navigate to the native-app directory.

    • Run npm i to install all dependencies.

    • Navigate to nodejs-assets/nodejs-project and run npm i to install the dependencies for the nodejs package for React Native.

    • Go back to the native-app/ directory and make a file called local.properties and add the following lines to it:

      sdk.dir=/home/<user>/Android/Sdk
      ndk.dir=/home/<user>/Android/Sdk/ndk/android-ndk-r21b
      
      Replace the <user> with your username

    • Next step is to copy the files in the native-app/dependency directory to the native-app/node_modules/nodejs-mobile-react-native/android/ directory. Replace the src folder with the one from dependency.

    • Once all this is done, go to the native-app/android/ folder and run the following:

      chmod +x gradlew
      ./gradlew clean

    • Connect your phone via USB to the computer and make sure that USB debugging is enabled. Verify that the device is connected using adb devices command in the terminal.

    • Run npx react-native run-android with the phone connected. This should start building the application

    • Open another terminal and run react-native start to fire the development server.

    • Once the build is completed, the application should be installed on your device.

    • Open the app and shake your device to open the developer settings. Alternately you can also press d on the terminal to start it. Go to settings -> debug server host & port -> and add your laptops ip followed by port number. Eg: 192.168.1.20:8081

    • The application can now be hot reloaded and the changes will be built and sent over the network.

  • Running the web/desktop client 💻

    The web client is written in React and the desktop client is ported in electron. The following steps can be followed to build the clients:

        cd intralan/web/
        # Install dependencies for the frontend
        npm i
    
        cd src/backend
        # Install dependencies for the backend
        npm i
    
        # Start the backend server
        nodemon server.js
    
        cd ..
        # Start the frontend
        npm start
    
        # For running the desktop client
        npm run electron-dev
    

    • After successfully completing the above steps, the application should be up locally on port 3000 and the peer server should be up on port 5000
    • Additionally, the electron window should start in case the last command was run.
