The configuration file for the goland service hot restart

Develop a web API or web project. After modifying the source code, you can view the effect without manually restarting it. It can be achieved using Air.

Install air: go get -v -u /cosmtrek/air (or after downloading all source code, go build, get, copy to $goroot/bin directory)

In the project directory, create a . file, modify the cmd configuration in [build], and set it to the command line command for the goland compiler:

cmd = "go build -o ./tmp/ ./"

The final configuration file is as follows:

# Config file for [Air](/cosmtrek/air) in TOML format
 
# Working directory
# . or absolute path, please note that the directories following must be under root.
root = "."
tmp_dir = "tmp"
 
[build]
# Just plain old shell command. You could use `make` as well.
cmd = "go build -o ./tmp/ ./"
# Binary file yields from `cmd`.
bin = "tmp/"
# Customize binary.
full_bin = "APP_ENV=dev APP_USER=air ./tmp/main"
# Watch these filename extensions.
include_ext = ["go", "tpl", "tmpl", "html"]
# Ignore these filename extensions or directories.
exclude_dir = ["assets", "tmp", "vendor", "frontend/node_modules"]
# Watch these directories if you specified.
include_dir = []
# Exclude files.
exclude_file = []
# It's not necessary to trigger build each time file changes if it's too frequent.
delay = 1000 # ms
# Stop to run old binary when build errors occur.
stop_on_error = true
# This log file places in your tmp_dir.
log = "air_errors.log"
 
[log]
# Show log time
time = false
 
[color]
# Customize each part's color. If no color found, use the raw app log.
main = "magenta"
watcher = "cyan"
build = "yellow"
runner = "green"
 
[misc]
# Delete tmp directory on exit
clean_on_exit = true

Open the project in goland and run the air command in Terminal to automatically monitor project code modification and automatically hot-start the service, making it easier to develop and debug.
