An easy-to-use library to download music from Deezer, heavily stolen inspired by GoDeez.

package main

	"context"
	"log"
	"os"

	"github.com/birabittoh/miri"
)

func main() {
	ctx := context.Background()

	arlCookie := os.Getenv("ARL_COOKIE")
	secretKey := os.Getenv("SECRET_KEY")

	opt := miri.SearchOptions{Limit: 1, Query: "eminem"}
	res, err := miri.SearchTracks(ctx, opt)
	if err != nil {
		log.Fatalf("failed to search tracks: %v", err)
	}
	if len(res) == 0 {
		log.Fatal("no tracks found")
	}

	track := res[0]

	cfg, err := miri.NewConfig(arlCookie, secretKey)
	if err != nil {
		log.Fatalf("failed to create config: %v", err)
	}

	c, err := miri.New(ctx, cfg) // new miri client
	if err != nil {
		log.Fatalf("failed to create Miri client: %v", err)
	}

	data, err := c.DownloadTrackByID(ctx, track.ID)
	if err != nil {
		log.Fatalf("failed to download track: %v", err)
	}

	if len(data) == 0 {
		log.Fatal("downloaded data is empty")
	}

	coverURL := track.CoverURL("xl")
	println(coverURL)
}

Here are the key variables you need to set in your config object:

1. ArlCookie

• What is it?: The arl_cookie is a session cookie used for authentication with Deezer. Without this cookie, the downloader cannot access your account to retrieve playlists, albums, or songs.
• How to retrieve it:
  1. Open your browser and log in to your Deezer account.
  2. Open the Developer Tools (right-click on the page and select “Inspect” or press F12).
  3. Navigate to the Application tab (in Chrome/Edge) or Storage tab (in Firefox).
  4. In the left panel, look for Cookies and select https://www.deezer.com.
  5. Find the arl cookie and copy its value.

2. SecretKey

• What is it?: The secret_key is a cryptographic value used to decrypt Deezer’s media files.
• Where to find it?: While we cannot provide the specific secret_key in this documentation, it can be found online through various sources or developer communities that focus on Deezer.
