The following example demonstrates how to compress a file using the gzip package:
// This example uses gzip but standard library also // supports zlib, bz2, flate, and lzw package main import ( "compress/gzip" "log" "os" ) func main() { // Create .gz file to write to outputFile, err := os.Create("test.txt.gz") if err != nil { log.Fatal(err) } // Create a gzip writer on top of file writer gzipWriter := gzip.NewWriter(outputFile) defer gzipWriter.Close() // When we write to the gzip writer // it will in turn compress the contents // and then write it to the underlying // file writer as well // We don't have to worry about how all // the compression works since we just // use it as a simple writer interface // that we send ...
