When I get started with developing websites in Go and gin framework, it's a pity that gin lacks live-reloading function. In fact, I tried fresh and it seems not much flexible, so I intended to rewrite it in a better way. Finally, Air's born. In addition, great thanks to pilu, no fresh, no air :)
Air is yet another live-reloading command line utility for Go applications in development. Just
air in your project root directory, leave it alone,
and focus on your code.
NOTE: This tool has nothing to do with hot-deploy for production.
- Colorful log output
- Customize build or binary command
- Support excluding subdirectories
- Allow watching new directories after Air started
- Better building process
The classic way to install
go get -u github.com/cosmtrek/air
macOS, Linux, Windows
The binary is published on the release page.
P.S. Great thanks mattn's PR for supporting Windows platform.
Please pull this docker image cosmtrek/air.
docker run -it --rm \ -w "<PROJECT>" \ -e "air_wd=<PROJECT>" \ -v $(pwd):<PROJECT> \ -p <PORT>:<APP SERVER PORT> \ cosmtrek/air -c <CONF>
For example, one of my project runs in docker:
docker run -it --rm \ -w "/go/src/github.com/cosmtrek/hub" \ -v $(pwd):/go/src/github.com/cosmtrek/hub \ -p 9090:9090 \ cosmtrek/air
For less typing, you could add
alias air='~/.air' to your
First enter into your project
The simplest usage is run
# firstly find `.air.toml` in current directory, if not found, use defaults air -c .air.toml
While I prefer the second way
# 1. create a new file touch .air.toml # 2. paste `air_example.toml` into this file, and **modify it** to satisfy your needs. # 3. run air with your config. If file name is `.air.toml`, just run `air`. air
See the complete air_example.toml
air -d prints all logs.
Please note that it requires Go 1.13+ since I use
go mod to manage dependencies.
# 1. fork this project # 2. clone it mkdir -p $GOPATH/src/github.com/cosmtrek cd $GOPATH/src/github.com/cosmtrek git clone firstname.lastname@example.org:<YOUR USERNAME>/air.git # 3. install dependencies cd air make ci # 4. explore it and happy hacking! make install
BTW: Pull requests are welcome~
Huge thanks to the following supporters. I've always been remembering your kindness.
