Services

Search

artists(query: string, limit: number = 3, offset: number = 0)

Searches for query on Musicbrainz, returning Observable<JSON> of limit number of results. Get Array of results by subscribing and calling result['artists'].

TODO: return Array[artists] directly.

Clean

artist(dirty: JSON)

Returns as an Object only necessary fields (name, id) from raw result['artists']['artist'] query from searchService.artists().

artist = {
    name : Dua Lipa,
    id :6f1a58bf-9b1b-49cf-a44a-6cefad7ae04f
}

recordings(dirty: Array<Object>)

Returns as an Object only necessary fields (code, title, id) from raw query from searchService.recordings().

recordings = {
    ...,
    [
        code : rollindidyousee,
        title : Rollin'/Did You See,
        id : 42087b88-6841-4988-b4b7-766a475131a1
    ],
    ...
}

Note: code is the unique identifier. There may be many recordings of the same song under different circumstances (e.g. location), all with their own id. The included id is just from one of them.

---

Database (Firebase Firestore)

addArtist(artist: object)

Checks if artist exists in Database, and adds if it does not.

getArtist(artistId: string): Observable<any>

Gets Observable artist of artistId. Get recordings by subscribing and calling artist.data().recordings.

addRecordings(recordings: object[], artistId: string)

Adds recordings to artist of artistId. Uses filter to remove recordings that already exist in database, then adds them. (However, it is probably faster and more efficient to just set(recordings) straightaway.)
