You-Tube Video Downloader API

This API provides functionality to retrieve information about YouTube videos, download videos, and manage downloaded files on the server.

Important

Use this repo as a Backend/Server for your Front-end Application.

---

Features

1. Can download YouTube videos in the highest possible quality to the lowest possible quality.

2. YouTube allows us to download 2160p video without audio. Still, in case the downloaded 2160p video has audio, the API combines the video (without audio) and audio separately using ffmpeg.

3. Similarly, YouTube allows us to download 1080p video without audio. If the downloaded 1080p video has audio, the API combines the video (without audio) and audio separately using ffmpeg.

Note

1. Before hitting any endpoints in the API, always use encodeURIComponent() for the URL. The :yt_link parameter must be encoded using encodeURIComponent().

2. When hitting the endpoint /video-download/:yt_link, send {"quality":"2160p"} from the front-end to specify the desired video quality.

3. When hitting the endpoint /:filePath, send {"fileName":"output.mp4"} from the front-end to specify the desired video file name.
