调试模式

命令

colon 框架自带调试模式，不管是前端还是后端，都可以启动调试模式，边修改代码，边编译运行服务。

对应的命令为 ./colon dev

[~/go-colon/colon/demo]$ ./colon dev
dev mode

Usage:
  colon dev [flags]
  colon dev [command]

Available Commands:
  all         dev mode from both frontend and backend
  backend     dev mode for backend, hot reload
  frontend    dev mode for frontend

Flags:
  -h, --help   help for dev

Use "colon dev [command] --help" for more information about a command.
  • 调试前端
  • 调试后端
  • 同时调试

调试前端

使用命令 ./colon dev frontend

要求当前编译机器安装 npm 软件，并且当前项目已经运行了 npm install，安装完成前端依赖。

[~/go-colon/colon/demo]$ ./colon dev frontend

> colon@0.1.0 serve ~/go-colon/colon/demo
> vue-cli-service serve

  - Network: http://172.24.34.34:8080

  Note that the development build is not optimized.
  To create a production build, run npm run build.

实际上是调用 npm run dev 来调试前端

调试后端

使用命令 ./colon dev backend

要求当前编译机器安装 go 软件，版本 > 1.17。

[~/go-colon/colon/demo]$  ./colon dev backend
./colon dev backend
build success please run ./colon direct
backend server: http://127.0.0.1:15060
proxy backend server: http://0.0.0.0:8073
[PID] 29034
app serve url: http://127.0.0.1:15060

可以通过 proxy backend server 地址进行访问：

http://0.0.0.0:8073/demo/demo

后端调试默认是最后一次操作后3秒启动后端编译启动命令。

colon 也允许通过配置修改这个等待时间。

可以配置 development/app.yaml 里面的 dev_fresh 参数修改这个等待时间。

同时调试

也可以选择同时调试，这个时候会同时运行调试前端和调试后端的程序

[~/go-colon/colon/demo]$ ./colon dev all

> colon@0.1.0 serve ~/go-colon/colon/demo
> vue-cli-service serve

 INFO  Starting development server...
