Module Usage

You can use Got to download large files in your go code, the usage is simple as the CLI tool:

package main

import "github.com/melbahja/got"

func main() {

	g := got.New()

	err := g.Download("http://localhost/file.ext", "/path/to/save")

	if err != nil {
		// ..
	}
}

For more see PkgDocs.

How It Works?

Got takes advantage of the HTTP range requests support in servers RFC 7233, if the server supports partial content Got split the file into chunks, then starts downloading and merging the chunks into the destinaton file concurrently.
