Golang zip file

To zip a file in Go, you can use the zip package from the Go standard library. It provides functions for creating and manipulating zip archives in Go.

A zip file is a compressed archive that contains one or more files. The zip package allows you to create, and add to existing zip files, extract files from zip files, and more.

How to create a zip file in Golang?

To create a zip file in Golang, use the zip.NewWriter() function.

To use the zip package in Go, import it into your program. Here’s an example of importing the zip package into your Go program.

import "archive/zip"

Once you import the zip package, use its functions to create and read zip files.

Here’s an example of how you can use the zip package to create a zip file in Go.

package main

import (
 "archive/zip"
 "log"
 "os"
)

func main() {
  file, err := os.Create("../new_zip_file.zip")
  if err != nil {
    log.Fatal(err)
  }
  defer file.Close()

  // Create a new zip writer
  wr := zip.NewWriter(file)
  defer wr.Close()

  // Add a file to the zip file
  f, err := wr.Create("app.txt")
  if err != nil {
   log.Fatal(err)
  }

  // Write data to the file
  _, err = f.Write([]byte("Hello Golang"))
  if err != nil {
   log.Fatal(err)
  }
}

In this example, we created a new file called new_zip_file.zip using the os.Create() function.

To create a new zip writer in Go, use the zip.NewWriter() function. The NewWriter() function accepts a file name as its argument and returns a Writer type used to write data to the zip file.

In short, we are creating a zip file of app.txt with the content “Hello Golang” in Go.

That’s it for this tutorial.
