Simple and Human Friendly Slack Client for Logging/Notification written in Go
go get "github.com/iktakahiro/slclogger/v2"package main
import (
"errors"
"github.com/iktakahiro/slclogger/v2"
)
func something() error {
return errors.New("an error has occurred")
}
func main() {
logger, _ := slclogger.NewSlcLogger(&slclogger.LoggerParams{
WebHookURL: "https://hooks.slack.com/services/YOUR_WEBHOOK_URL",
})
if err := something(); err != nil {
logger.Error(err, "Error Notification")
}
}When you execute the above sample code, your Slack channel will receive the message.
The default log level is Info. You can set it when initializing a SlcLogger struct.
package main
import (
"github.com/iktakahiro/slclogger/v2"
)
func main() {
logger, _ := slclogger.NewSlcLogger(&slclogger.LoggerParams{
WebHookURL: "https://hooks.slack.com/services/YOUR_WEBHOOK_URL",
LogLevel: slclogger.LevelDebug,
})
logger.Debug("Debug Message")
logger.Info("Info Message")
logger.Warn("Warn Message")
logger.Error("Error Message")
}
You can also change the level at any time.
package main
import (
"github.com/iktakahiro/slclogger/v2"
)
func main() {
logger, _ := slclogger.NewSlcLogger(&slclogger.LoggerParams{
WebHookURL: "https://hooks.slack.com/services/YOUR_WEBHOOK_URL",
})
logger.SetLogLevel(slclogger.LevelWarn)
// The following notification will be ignored.
logger.Debug("Debug Message")
}All options are shown below.
package main
import (
"github.com/iktakahiro/slclogger/v2"
)
func main() {
logger, err := slclogger.NewSlcLogger(&slclogger.LoggerParams{
WebHookURL: "https://hooks.slack.com/services/YOUR_WEBHOOK_URL",
DefaultTitle: "Default Title",
DefaultChannel: "general",
DebugChannel: "debug-channel",
InfoChannel: "info-channel",
WarnChannel : "warn-channel",
ErrorChannel : "error-channel",
LogLevel: slclogger.LevelWarn,
IconURL: "https://example.com",
UserName: "My Logger",
})
}| Param | Default Value |
|---|---|
| WebHookURL (require) | -- |
| DefaultTitle | "Notification" |
| DefaultChannel | "" (When this param is omitted, the default channel of specified WebHook is used.) |

If you want to handle errors, use SlcErr.
if err := logger.Info("info message"); err != nil {
if slcErr, ok := err.(*slclogger.SlcErr); ok {
fmt.Println(slcErr)
fmt.Println(slcErr.Code)
}
