Energy is framework for Go to build desktop applications based on CEF
[中文](README.zh_CN.md) | English --- [](https://github.com/energye/energy) [](https://github.com/energye/energy/releases) [](http://www.apache.org/licenses/LICENSE-2.0)   --- ### [Project Introduction](https://energy.yanghy.cn/#/course/6342d92c401bfe4d0cdf6065/6350f94ca749ba0318943f25) Energy is a framework developed by Golang based on CEF(Chromium Embedded Framework), embedded with [CEF](https://bitbucket.org/chromiumembedded/cef) binary > [energy](https://github.com/energye/energy) is a framework developed by Golang based on CEF(Chromium Embedded > Framework), embedded with [CEF](https://bitbucket.org/chromiumembedded/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 ### Built-in dependency&integration - [](https://github.com/energye/golcl) - [%20CEF4Delphi-green)](https://github.com/salvadordf/CEF4Delphi) ### [Development environment](https://energy.yanghy.cn/#/course/6342d92c401bfe4d0cdf6065/63511b14a749ba0318943f3a) > 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](https://github.com/energye/energy) project, or use the precompiled command line tool > directly [Download address](https://energy.yanghy.cn/#/course/6342d92c401bfe4d0cdf6065/63511b14a749ba0318943f3a) > >If using pre compiled command-line tools, the following steps can be skipped
> > `go get github.com/energye/energy/v2` > > Enter the [energy](https://github.com/energye/energy) command line directory > > `cd energy/cmd/energy` > > Install command line tools > > `go install` > > Execute the installation command > > `energy install .` ### Getting Started Guide - [Transfer gate](https://energy.yanghy.cn) * [Course](https://energy.yanghy.cn/#/course/6342d92c401bfe4d0cdf6065/6350f94ca749ba0318943f25) * [Example](https://energy.yanghy.cn/#/example/6342d986401bfe4d0cdf6067/634d3bd5a749ba0318943eb6) * [Document](https://energy.yanghy.cn/#/document/6342d9a4401bfe4d0cdf6069/0) ### Quick Get Start > Use [energy](https://github.com/energye/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 ```go package main import ( "github.com/energye/energy/v2/cef" ) func main() { //Global initialization must be called by every application cef.GlobalInit(nil, nil) //Create application cefApp := cef.NewApplication() //Set URL cef.BrowserWindow.Config.Url = "https://www.yanghy.cn" //Run App cef.Run(cefApp) } ``` --- ### Run app - Windows、Linux > `go run simple.go` - MacOS > `go run simple.go energy_env=dev` ### Pack Project [reference](https://energy.yanghy.cn/#/course/6342d92c401bfe4d0cdf6065/636e397ba749ba01d04ff595) 1. Compile: Go program compilation `go build simple.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 - `go build -ldflags "-H windowsgui -s -w"` > `-ldflags` > >> `-H windowsgui` optional: windows hide cmd black window >> >> `-w` optional: Removing debugging information can reduce the size of the execution file >> >> `-s` optional: Removing Symbol table information can reduce the size of the execution file --- --- ### System support    | | 32 Bit | 64 Bit | Test System Version | |-----------|--------------------------------------------------------------------------------------------|--------------------------------------------------------------------------------------------|------------------------------------| | Windows |  |  | Windows 7、Windows 10 | | MacOS |  |  | MacOSX 10.15 | | Linux |  |  | Deepin20.8、Ubuntu18.04、LinuxMint21 | | Linux ARM |  |  | Kylin-V10-SP1-2107 | --- ### Thanks Jetbrains
