This program allows you to download a osu beatmap set, example:
# Download a beatmap set
osu-downloader song https://osu.ppy.sh/beatmapsets/787134
# You can pass the id directly as well
osu-downloader song 78713
# Use -s (for small) or --no-video to download videoless version of beatmaps
osu-downloader -s song 787134
You can also download the first n songs of a user's highscore page:
# First 5 (default n) beatmaps from user url
osu-downloader highscores https://osu.ppy.sh/users/124493
# Just like the song command, you can simply pass the id and use -s flag
osu-downloader -s highscores 124493
# To change the number of songs downloaded (try not to piss peppy off, this program was made for educational purposes)
osu-downloader -n 10 hs 124493
All songs downloaded go to ./songs directory from wherever you ran the program.
Since osu downloads are protected by authentication, you need to create a session file in the working directory with your session cookie.
To get this cookie, install this extension (or any equivalent one), log in to osu's website, then copy the value of this cookie to your session file.
sudo apt install curl
curl -sL https://deb.nodesource.com/setup_10.x | sudo bash -
sudo apt install nodejs
To install the necessary dependencies, run npm install
To build after changes, run npm run build
Now you can call the program with node .
npm link
Now you can run osu-downloader as if it was installed.
To unlink - you guessed it: npm unlink
