Overview

The Cache configuration can be set in the config.py file.

Extension: flask-caching

Usage

Assembly exposes @response.cache to cache enpoint. The decorator will use request.path by default for the cache_key

from assembly import Assembly, response, date

class Index(Assembly):

    @response.json
    def index(self):
        return {
            "description": "not cached",
            "date": date.utcnow()
        }

    @response.cache(10)
    @response.json
    def cached(self):
        return {
            "description": "cached",
            "date": date.utcnow()
        }
