golang web项目热部署air库的使用

创建一个web项目

mkdir test_air
cd test_air
code .

初始化一下项目

go mod init test_air

创建一个gin项目

创建一个gin项目，这里以gin为例，其他go web项目都可以。

package main

import "github.com/gin-gonic/gin"

func main() {
	r := gin.Default()
	r.GET("/ping", func(c *gin.Context) {
		c.JSON(200, gin.H{
			"message": "Psych air test...",
		})
	})
	r.Run()
}

下载安装air

go install github.com/cosmtrek/air@latest

注意：这里要用install，而不是get，install会生成可执行文件，并且保证你的Gopath/bin已经配置到了系统环境变量下面

启动air

air

初始化air

air init

会生成一个air的配置文件.air.toml，内容如下：

root = "."
testdata_dir = "testdata"
tmp_dir = "tmp"

[build]
  args_bin = []
  bin = "tmp\\main.exe"
  cmd = "go build -o ./tmp/main.exe ."
  delay = 1000
  exclude_dir = ["assets", "tmp", "vendor", "testdata"]
  exclude_file = []
  exclude_regex = ["_test.go"]
  exclude_unchanged = false
  follow_symlink = false
  full_bin = ""
  include_dir = []
  include_ext = ["go", "tpl", "tmpl", "html"]
  kill_delay = "0s"
  log = "build-errors.log"
  send_interrupt = false
  stop_on_error = true

[color]
  app = ""
  build = "yellow"
  main = "magenta"
  runner = "green"
  watcher = "cyan"

[log]
  time = false

[misc]
  clean_on_exit = false

[screen]
  clear_on_rebuild = false
