metadata-filter
A module for cleaning up artist, album, and song names.
Installation
Install using npm
npm i @web-scrobbler/metadata-filter
Include via CDN
<script src="https://unpkg.com/@web-scrobbler/metadata-filter@latest/dist/filter.min.js"></script>
Usage
If you want to use this module in a project which is built with a bundler (e.g. webpack), you can use CommonJS-like or ES6 imports:
// CommonJS style
const MetadataFilter = require('@web-scrobbler/metadata-filter');
// ES6 style
import * as MetadataFilter from '@web-scrobbler/metadata-filter';
MetadataFilter.removeRemastered(yourInput);
In a browser you can access to the module by using the global MetadataFilter
object:
<!-- Assume you have `metadata-filter` module included with `script` tag -->
<script lang="javascript">
MetadataFilter.removeRemastered(yourInput);
</script>
Single filter functions
You can call filter functions for basic, one-line filter functionality. These filter functions are intended to be used on a single field, such as an artist, album, or track.
However, it is possible (not officially supported) to use some of these on combined fields ("Artist - Song", "Artist - Album"), as in the third example below.
console.log(MetadataFilter.removeRemastered('Jane Doe (Remastered)')); // Jane Doe
console.log(MetadataFilter.removeVersion('Get Lucky (Album Version)')); // Get Lucky
console.log(
MetadataFilter.youtube(
'Car Bomb - Scattered Sprites (Official Music Video)'
)
); // Car Bomb - Scattered Sprites
See src/functions.ts for more details.
Combine filter functions
You can also use multiple filter functions on a string at once by creating a
MetadataFilter
object which combines multiple functions from above,
or by using one of the pre-existing filter objects.
First, create a filter set. This is a set of filter functions for different fields.
const filterSet = {
track: [
MetadataFilter.removeRemastered,
MetadataFilter.fixTrackSuffix,
MetadataFilter.removeLive,
],
album: [
MetadataFilter.removeRemastered,
MetadataFilter.fixTrackSuffix,
MetadataFilter.removeLive,
],
};
Then, construct a MetadataFilter
using this filter set.
const filter = MetadataFilter.createFilter(filterSet);
console.log(filter.filterField('album', 'Nevermind (Remastered)')); // Nevermind
console.log(filter.filterField('track', 'In Bloom - Nevermind Version')); // In Bloom (Nevermind Version)
Predefined filters
There are also predefined filters available for easy access. For example,
the above filter set can be acquired using createSpotifyFilter()
function:
const filter = MetadataFilter.createSpotifyFilter();
See src/filters.ts for more details.
Extending filters
Finally, you can take existing MetadataFilter
objects and extend them with another filter.
This is done by providing the .extend()
method with another MetadataFilter
object.
const filter = MetadataFilter.createSpotifyFilter();
filter.extend(MetadataFilter.createAmazonFilter());
// This would also work: filter.extend(MetadataFilter.createFilter(filterSet));
console.log(
filter.filterField('track', 'Seasons in the Abyss (Album Version)')
); // Seasons in the Abyss
As an alternative, you can use the .append()
method to apply a filter set to
an existing MetadataFilter
object.
const filter = MetadataFilter.createFilter({ track: filterTrack });
filter.append({ artist: filterArtist });
Since these methods return a MetadataFilter
instance, you can chain method calls.
const filter = MetadataFilter.createFilter({ track: filterTrack }).append({
artist: filterArtist,
});
