metadata-filter-service

metadata-filter as a service.

Usage

An online instance is available at https://metadata-filter.vercel.app/.

API

The format of request URL is /api/:filter?query, where

• filter is a name of any available filters
• query is a filter query string containing fields to filter and their values

For example, query for filtering track field is track=TrackName. You can put multiple fields as well - join them with ampersand.

The response is a JSON in the following format:

interface SuccessResponse {
	status: 'success';
	data: {
		[field: string]: string;
	};
}

interface ErrorResponse {
	status: 'error';
	message: string;
}

Available filters

The service uses predefined filters from metadata-filter:

• Amazon (/api/amazon)
• Remastered (/api/remastered)
• Spotify (/api/spotify)
• Tidal (/api/tidal)
• YouTube (/api/youtube)

Each filter can process different fields. See src/filters.ts of metadata-filter for details.

Example

For example, we want to filter "If I Get High (Official Video)" track name with YouTube filter.

Requesting /api/youtube?track=If%20I%20Get%20High%20(Official%20Video) will return a response with filter result in JSON format.

{
	"status": "success",
	"data": {
		"track": "If I Get High"
	}
}
