Bahamut Anime Downloader

This tool is used to download low quality Anime from Bahamut.

It serves as a component of baha-anime-skip, which detects the opening and ending songs and add skip button to Bahamut Anime.

Features

By giving the sn of the anime, this tool can do the following things:

• Download the meta-m3u8 file, and parse it
• Download the m3u8 playlist, and parse it
• Download the ts files, and decrypt them

It does not merge the ts files into a single mp4 file, if you want to do so, you can use ffmpeg.

It is platform independent, you can pass any custom fetch and subtle implementation to it.

Example

import fs from "node:fs";
import path from "node:path";
import { Downloader } from "baha-anime-dl";

const SN = 34886;

const dir = "tmp";
if (!fs.existsSync(dir)) {
    fs.mkdirSync(dir);
}

main();

async function main() {
    const downloader = new Downloader();

    const download = downloader.download(SN);
    const meta = await download.meta;
    fs.writeFileSync(path.join(dir, "meta.m3u8"), meta);

    const playlist = await download.playlist;
    fs.writeFileSync(path.join(dir, "playlist.m3u8"), playlist);

    for (let i = 0; i < download.segments.length; i++) {
        const segment = download.segments[i];
        segment.content.then((content) => {
            fs.writeFileSync(path.join(dir, segment.filename), Buffer.from(content));
        });
    }
}
