Setup

[adsense size='1' ]

Requirements:

• Latest node.js and yarn (or npm if you prefer) to run the api server and web gui
• libimobiledevice brew install libimobiledevice on macOS
• Any desktop browser you like

Starting the gui

This is the easiest way to start if you don’t want to modify the project.

• Open the terminal and cd into the project directory.
• If it is the first time you cloned this project, you need to install npm dependencies and build the frontend. Run npm install or yarn for the node.js requirements on the first time. Then npm run build (or yarn run build) to build the bundle.
• Then use npm start or yarn start
• Open http://localhost:31337 in your browser. If the port 31337 is in use, set an environment variable PORT to use an alternative port: PORT=12345 npm start

Development (optional)

For those who want to contribute, you may probably need to restart the api server and reload web page each time you make a change. The following steps enable livereload.

API server

Webpack server

Now open localhost:8080 in a browser.
