goroutine 作为 golang 并发实现的核心组成部分，非常容易上手使用，但却很难驾驭得好。我们经常会遭遇各种形式的 goroutine 泄漏，这些泄漏的 goroutine 会一直存活直到进程终结。它们的占用的栈内存一直无法释放、关联的堆内存也不能被 GC 清理，系统的可用内存会随泄漏 goroutine 的增多越来越少，直至崩溃！

添加goreleaser 支持

goreleaser init

获取 Github Token
访问 Settings / Developer Settings / Personal access tokens，点击 Generate new token 按钮，生成一个新的 Token，将 Token 保存到 ~/.config/goreleaser/github_token 文件中或者 export GITHUB_TOKEN="YOUR_GH_TOKEN"。

DI

Google wire 3.3k

https://github.com/google/wire

Wire 可以生成 Go 源码并在编译期完成依赖注入。它不需要反射机制或 Service Locators

好处：

方便 debug，若有依赖缺失编译时会报错
因为不需要 Service Locators，所以对命名没有特殊要求
避免依赖膨胀。生成的代码只包含被依赖的代码，而运行时依赖注入则无法作到这一点
依赖关系静态存于源码之中，便于工具分析与可视化

Fyne

https://github.com/fyne-io/fyne 24.9k

Cross platform GUI in Go based on Material Design https://fyne.io/

跨平台支持手机端: go run -tags mobile main.go

fyne package -os android -appID my.domain.appname
fyne install -os android

fyne package -os ios -appID my.domain.appname
fyne package -os iossimulator -appID my.domain.appname

支持web

If you’re using an older version of Go (<1.16), you should install fyne using go get fyne.io/fyne/v2/cmd/fyne

go install fyne.io/fyne/v2/cmd/fyne@latest
fyne serve # 在线运行

fyne package -os web

go install fyne.io/fyne/v2/cmd/fyne@latest
fyne package -os darwin -icon myapp.png
fyne package -os linux -icon myapp.png
fyne package -os windows -icon myapp.png

# 在当前系统安装应用
fyne install -icon myapp.png

请注意，默认情况下，Windows应用程序是从命令提示符加载的，这意味着，如果单击图标，则可能会看到命令窗口。要解决此问题，请在运行或构建命令中添加参数-ldflags="-H windowsgui"。

避免出现控制台:
go run -ldflags="-H windowsgui"

Prerequisites
https://fyne.io/develop/
Windows

Download Go from the download page and follow instructions
Install one of the available C compilers for windows, the following are tested with Go and Fyne:
- MSYS2 with MingW-w64 - msys2.org
- TDM-GCC - tdm-gcc.tdragon.net
- Cygwin - cygwin.com
In Windows your graphics driver will already be installed, but it is recommended to ensure they are up to date.

环境安装

Install Go
Install Gcc
go get fyne.io/fyne/v2@latest (or, if using Go before 1.16, then go get fyne.io/fyne/v2)
You can test your installation using the Fyne Setup app (检查环境: 检查你的环境是否可以进行fyne开发)

esbuild

https://github.com/evanw/esbuild
这是一个 JavaScript 打包和压缩程序。它用于打包 JavaScript 和 TypeScript 代码以在网络上分发。
我目前有两个基准测试用于衡量 esbuild 的性能。对于这些基准测试，esbuild 比我测试的其他 JavaScript 打包程序快至少 100 倍：https://docs.breword.com/evanw-esbuild/

类似工具：

Webpack ， Rollup 或 Parcel 用于打包
Babel 或 TypeScript 用于转译
Terser 或 UglifyJS 用于代码压缩

使用者：

Vite
Snowpack

Vite，snowpack使用了esbuild

esbuild 不可能替代 webpack、parcel 等构建工具

multimap: an associative container that permits multiple entries with the same key.
queue: a First In First Out (FIFO) queue.
rope: a generic rope, which is similar to an array but supports efficient insertion and deletion from anywhere in the array. Ropes are typically used for arrays of bytes, but this rope is generic.
prope: a persistent version of the rope, which allows for keeping different versions of the rope with only a little extra time or memory.
stack: a LIFO stack.
trie: a ternary search trie.
ulist: an un-rolled doubly-linked list.
