GPU Acceleration

If you are running NicelandVPN on Linux, you might need to disable GPU acceleration. That can be done by running Niceland with the -disableGPU flag

$ ./NicelandVPN -disableGPU

Building from source

• install nodejs and npm
• install npm packages for the frontend

$ cd [PROJECT_ROOT]/frontend
$ npm install

• install golang
• install wails.io
• build the app

$ cd [PROJECT_ROOT]
wails build -webview2 embed

• the final build product can be found inside the build/bin folder

Setup up for development

• install nodejs and npm
• install npm packages for the frontend

$ cd [PROJECT_ROOT]/frontend
$ npm install

• install Golang
• install Wails.io
• start the Wails development server
• NOTE: before starting the server we recommend setting ENABLE_INTERFACE to false in the main.go file. This will prevent Wails from initializing the default tunnel tap interface every time it reloads due to changes in files.

$ cd [PROJECT_ROOT]
wails dev

General development guide

• Indentation: 1 Tab.
• Naming should follow a Camel Case convention. Some exceptions may apply.

Folders

• build/bin: final build products
• build/windows-custom: Windows build staging grounds, build scripts, sign scripts, etc.
• build/darwin-custom: MacOs build staging grounds, sign scripts, .app files, etc.
• core: the code for the VPN client
• frontend/src: The GUI source files
• frontend/Wailsjs: Wails.io generated javascript files
• launcher: MacOS-specific launching mechanism
• parking: code examples that might be interesting to look at/use later.

Notes on the Golang core

• Yes, there are race conditions. Most of them are on purpose. If you want to fix race conditions, then please create an issue first so we can discuss it.
• Avoid using Locks or sync maps whenever possible.
• Sacrificing memory for performance is generally accepted, however, we do not want to use up too much memory. Changes that implement this trade-off need to be evaluated.
• Niceland has a few async routines that manage the state, and we would like to keep these routines to a minimum. If you want to implement something that needs to happen on an interval, it should preferably be implemented in the "StateMaintenance" routine.

Using ReactJS

• Custom functions and methods should start with an uppercase letter.

• Import are sorted by type:

  1. ReactJS imports
  2. Modules from NPM
  3. Wails / Golang bindings
  4. Internal components and libraries

• We want to keep the complexity of this project to a minimum. Any ReactJS functionality that is not generally accepted will need to be reviewed on a per-case basis.

• ReactJS functionality that is generally accepted:

  • useState
  • useEffect
  • useNavigate

Pull Requests

• No copy/paste from machine learning tools.

Pull requests should have a short descriptive title and a long description when needed, listing everything that has been modified or added, but more importantly why it was modified or added.
