Project Introduction

• Energy is a GUI framework developed in Go, based on LCL and CEF(Chromium Embedded Framework), which is used to develop cross-platform desktop applications for Windows, MacOS, and Linux.
• LCL alone can create lightweight native applications, or can be combined with CEF to create more feature-complete applications.
• Construct cross-platform desktop applications that support Windows, Linux, and MacOS using Go and web technologies (HTML + CSS + JavaScript).

Characteristic

• Rich CEF API and LCL system native widgets
• Development environment is simple and the compilation speed is fast. Only need Go and Energy.
• Cross-Platform: You can package your code as Windows, domestic UOS, Deepin, Kylin, MacOS and Linux
• Responsibilities
  • Go: Go is responsible for creating Windows, configuring CEF and implementing functions, creating various UI components, calling the low level of the system and some functions that JS cannot handle, such as: file flow, security encryption, high-performance processing, etc.
  • Web: HTML + CSS + JavaScript is responsible for the function of the client interface, you can make any interface you want.
• Front-end technology: Support mainstream frameworks, such as Vue, React, Angular or pure HTML+CSS+JS.
• Event driven: High performance event driven communication based on IPC allowing intercommunication between Go and Web.
• Resource loading: You can either read local resources or resources built into execution files either with or without HTTP services.

Built-in dependency&integration

Development Environment

Basic needs

• Golang >= 1.18
• Energy (CEF, liblcl)

Quick Start

• Getting Started

Run a simple application by three steps

1. Install development environment: energy install
2. Initiate an Application: energy init
3. Run the Application: go run main.go

sample code

main.go

package main

import (
    "github.com/energye/energy/v2/cef"
)

func main() {
     //Global initialization
     cef.GlobalInit(nil, nil)
     //Create an application
     app := cef.NewApplication()
     //Specify a URL address or local HTML file directory
     cef.BrowserWindow.Config.Url = "https://energye.github.io"
     //Run Application
     cef.Run(app)
}

Build

1. Build：energy build
2. Package：energy package
3. Package Type：
   • windows: Using nsis create exe installation package
   • linux: Using dpkg create deb installation package
   • macos: Generate xxx.app
