MetaSpotify

Python wrapper for the Spotify metadata API

The Spotify metadata API limitations are 10 requests per second per IP. Spotify pushes use of a If-Modified-Since header using the original request's Last-Modified header. See Spotify's Caching requests for more information. As this would require a backend to store this information, and with most applications already having a caching system implemented, MetaSpotify takes the caching function as an argument within metaspotify.api() to cache these results, not store them.

import metaspotify

ms = metaspotify.api() # Without any parameters, the MetaSpotify SimpleCache is
                       # loaded.

# This is an example of using Flask-Cache with MetaSpotify inside a Flask app.
from flask import Flask
from flask_cache import Cache

app = Flask('application')
cache = Cache(app)

# ...

ms = metaspotify.api(
    cache_function=cache.memoize, cache_arguments={'timeout': 60})

# Works like @cache.memoize(timeout=60)

What the example using Flask-Cache does is tell MetaSpotify to use the cache.memoize decorator with kwargs timeout=60. MetaSpotify calls a given decorator, as most caching libraries use decorators for this.

The caching functions are called within search and lookup
