Wails is a project that enables you to write desktop apps using Go and web technologies.
Consider it a lightweight and fast Electron alternative for Go. You can easily build applications with the flexibility and power of Go, combined with a rich, modern frontend.
Wails doesn't hold back with the eye candy either! This is xbar - a desktop application for MacOS written using Wails. It has menus, supports light and dark desktop themes, and the main window uses translucency that gives it that 'frosty' effect of a native app.
Wails uses a purpose built library for handling native elements such as Window, Menus, Dialogs, etc, so you can build good-looking, feature rich desktop applications.
It does not embed a browser, so it is resource efficient. Instead, it uses the native rendering engine for the platform. On Windows, this is the new Microsoft Webview2 library, built on Chromium.
When you run your application in "dev" mode, Wails will build your application as a native desktop application, but will read your assets from disk. It will detect any changes to your Go code and automatically rebuild and relaunch your application.
When changes to your application assets are detected, your running application will "reload", reflecting your changes almost immediately.
If you prefer to debug and develop in a browser then Wails has you covered. The running application also has a webserver that will run your application in any browser that connects to it. It will even refresh when your assets change on disk.
When you're ready to do the final build of your application, the CLI will compile it down to a single executable, with all the assets bundled into it. On Windows and MacOS, it is possible to create a native package for distribution. The assets used in packaging (icon, info.plist, manifest file, etc) are part of your project and may be customised, giving you total control over how your applications are built.
The Wails CLI provides a hassle-free way to generate, build and bundle your applications. It will do the heavy lifting of creating icons, compiling your application with optimal settings and delivering a distributable, production ready binary.
