How can I integrate Zap logging with my Go application?

To integrate Zap logging in your Go application, first, you need to install the Zap package using go get go.uber.org/zap. Then, you can create a logger instance.

Can you show me a code example for that?

Sure! Here's a simple example:

package main

import (
    "go.uber.org/zap"
)

func main() {
    logger, _ := zap.NewProduction()
    defer logger.Sync() // flushes buffer, if any
    logger.Info("Hello, Zap logging!")
}

What are the different logging levels available in Zap?

Zap supports several logging levels: Debug, Info, Warn, Error, DPanic, Panic, and Fatal. You can set the level when creating the logger.

Is it possible to log to a file instead of the console?

Yes, you can configure Zap to log to a file by using a zapcore.Core with a file output. You would need to set up a file writer in your logger configuration.
