How do I configure Logrus for my Go application?

To configure Logrus, first install it using go get github.com/sirupsen/logrus. Then, you can set it up like this:

package main

import (
    "github.com/sirupsen/logrus"
)

func main() {
    log := logrus.New()
    log.SetFormatter(&logrus.TextFormatter{}) // Set the log format
    log.SetLevel(logrus.InfoLevel) // Set the log level
    log.Info("Logrus is configured!")
}

Can I change the log format to JSON?

Yes, you can change the log format to JSON by using log.SetFormatter(&logrus.JSONFormatter{}). This will output logs in JSON format.

How can I log to a file instead of the console?

To log to a file, you can create a file and set it as the output for Logrus:

file, err := os.OpenFile("logfile.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
if err == nil {
    log.Out = file
} else {
    log.Info("Failed to log to file, using default stderr")
}
