Energy is the framework for Go to build desktop applications based on CEF

中文 | English

Project Introduction

Energy is a framework developed by Golang based on CEF(Chromium Embedded Framework), embedded with CEF binary

energy is a framework developed by Golang based on CEF(Chromium Embedded Framework), embedded with CEF binary

Use Go and Web technology (HTML+CSS+JavaScript) to build cross-platform desktop applications that support Windows, Linux and MacOS

Knowledge of the front-end technology stack and some knowledge of the Go language is required

Characteristic

• development environment is simple and the compilation speed is fast. Only the Go development environment and the CEF binary framework that Energy depends on are needed
• cross-platform: A set of code can be packaged into Windows, domestic UOS, Deepin, Kylin, MacOS, Linux
• Language responsibilities

• Go: Go is responsible for window creation, CEF configuration and function implementation, creation of various UI components, low-level system calls, and functions that JS cannot handle, such as file stream, security encryption, high-performance processing, etc., which can be developed as a pure backend
• Web: HTML + CSS + JavaScript responsible for the function of the client interface, make any interface you want, can be used as a pure front-end development

• front-end technology: Support mainstream front-end frameworks, such as Vue, React, Angular or pure HTML+CSS
• event driven: High performance event driven, IPC based communication, Go and Web side is very convenient function call and data interaction

Go interacts with the Web

The Go and Web technologies are based on IPC communication. Data and event triggering can be exchanged between Go and Web without using the http interface, which is as simple as calling the functions of the language itself

Define JS binding type variables in Go and provide them to JS on the Web side to realize data synchronization of Go variables or structural objects

Listen for events in JS and trigger JS events in Go to achieve Go calling JS functions and passing parameter

Listen for events in Go and trigger Go events in JS to achieve JS calling Go functions and passing parameters

Built-in dependency&integration

Development environment

Install automatically using the energy command line tool

Basic needs

• golang >= 1.18

• energy development environment

Use the energy command line tool to automatically install the development environment

Get energy project, or use the precompiled command line tool directly Download address

1. go get github.com/energye/energy

Enter the energy command line directory 2. cd energy/cmd/energy

Install command line tools 3. go install

Execute the installation command 4. energy install .

Getting Started Guide - Transfer gate

• course
• example
• document

Quick Get Start

Use energy Command line tool automatic installation environment dependency energy install .

Take example/simple as an example

Update latest release dependency

go mod tidy

Run simple in the IDE or go run simple.go

example/simple Code

package main

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

func main() {
	//Global initialization must be called by every application
	cef.GlobalInit(nil, nil)
	//Create application
	cefApp := cef.NewApplication(nil)
	//Set URL
	cef.BrowserWindow.Config.Url = "https://energy.yanghy.cn"
	//Run App
	cef.Run(cefApp)
}

Pack Project reference

1. Compile: Go program compilation go build xxx. go If you use resource built-in (HTML, CSS, JavaScript, Image, etc.), the resource will be compiled into the execution file
2. Copy: copy the execution file to the CEF directory of the ENERGY environment
3. Packaging: use the installation package tool to make it as an installation package, Or refer to the production of installation package for each system platform
4. Finally: the compiled program or installation package and CEF directory no longer need to configure the environment, and can be run directly in the CEF root directory

Go Compile Command

1. Compress and hide the cmd window go build -ldflags "-H windowsgui -s -w", Note: Windows needs to hide the CMD window
2. Compress go build -ldflags "-s -w"
3. Uncompressed go build
