How to use
- Define a config structure, like below:
type RestfulConf struct {
ServiceName string `json:",env=SERVICE_NAME"` // read from env automatically
Host string `json:",default=0.0.0.0"`
Port int
LogMode string `json:",options=[file,console]"`
Verbose bool `json:",optional"`
MaxConns int `json:",default=10000"`
MaxBytes int64 `json:",default=1048576"`
Timeout time.Duration `json:",default=3s"`
CpuThreshold int64 `json:",default=900,range=[0:1000]"`
}
- Write the yaml, toml or json config file:
- yaml example
# most fields are optional or have default values
port: 8080
logMode: console
# you can use env settings
maxBytes: ${MAX_BYTES}
- toml example
# most fields are optional or have default values
port = 8_080
logMode = "console"
# you can use env settings
maxBytes = "${MAX_BYTES}"
- Load the config from a file:
// exit on error
var config RestfulConf
conf.MustLoad(configFile, &config)
// or handle the error on your own
var config RestfulConf
if err := conf.Load(configFile, &config); err != nil {
log.Fatal(err)
}
// enable reading from environments
var config RestfulConf
conf.MustLoad(configFile, &config, conf.UseEnv())
