dlfetch

dlfetch is a Go library designed to make file downloading easy and efficient. It uses Go's concurrency to handle multiple downloads, managed by a number of configurable workers. It also includes error handling and on completion callbacks.

Usage Example

package main

import "github.com/hritikr/dlfetch"

func main() {
    // Create a new Fetcher instance with default configuration
    fetcher := dlfetch.New()
    
    // Add a download request to the Fetcher's queue
    fetcher.Enqueue(dlfetch.DownloadRequest{
        ID: "example_file",
        URL: "https://example.com/file",
    })

    // Start processing download requests
    fetcher.Start()

    // When finished, stop the Fetcher
    fetcher.Stop()
}

For a more complete usage example, see the example/example.go in this repository.

Functionality

dlfetch includes versatile configurability via functional options that allow you to:

• Change the default HTTP client
• Set the number of concurrent workers
• Specify the directory where downloaded files are saved
• Define custom behavior when a download completes or encounters an error

You can also add and manage multiple download requests at once using the EnqueueMany() function.

Installation

go get -u github.com/hritikr/dlfetch
