可以使用这个库实现项目的自动重载

修改代码之后自动重新运行项目

下载

如果是go1.25环境以上的，直接go install下载

go install github.com/air-verse/air@latest

也可以在release里面直接下载可执行文件，然后把它加到环境变量里面

https://github.com/air-verse/air/releases/download/v1.63.4/air_1.63.4_windows_arm64.exe

用法

命令行的用法

air --build.cmd "go build -o bin/api cmd/run.go" --build.entrypoint "./bin/api" --build.exclude_dir "templates,build"

--build.cmd 编译命令

--build.entrypoint 执行的命令

--build.exclude_dir 排除的目录

配置文件的用法

先用air init生成配置文件

air init

配置文件

#:schema https://json.schemastore.org/any.json

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

[build]
  args_bin = []
  bin = "tmp\\main.exe"
  cmd = "go build -o ./tmp/main.exe ."
  delay = 1000
  entrypoint = ["tmp\\main.exe"]
  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"]
  include_file = []
  kill_delay = "0s"
  log = "build-errors.log"
  poll = false
  poll_interval = 0
  post_cmd = []
  pre_cmd = []
  rerun = false
  rerun_delay = 500
  send_interrupt = false
  stop_on_error = false

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

[log]
  main_only = false
  silent = false
  time = false

[misc]
  clean_on_exit = false

[proxy]
  app_port = 0
  enabled = false
  proxy_port = 0

[screen]
  clear_on_rebuild = false
  keep_scroll = true

运行时指定配置文件

# 默认就是读取 .air.toml文件
air -c .air.toml
