Flask-Aggregator

================

.. image:: https://img.shields.io/pypi/v/flask-aggregator.svg

Batch the GET requests to your API into a single POST. Save requests latency and

reduce REST chatiness.

I was inspired by `this article

`_

from 3scale, and by `their NGINX aggregator

`_ - but I wanted something simpler.

What does it do?

----------------

Flask-Aggregator adds an endpoint to your Flask application that handles

multiple GET requests in a single POST, and returns the response of each GET

request in a JSON stream.

What does that mean?

--------------------

It means that instead of sending multiple GET requests:

.. code-block:: sh

   -> GET /route1

   <- answer1

   -> GET /route2

   <- answer2

   -> GET /route3

   <- answer3

You can now just send a single POST that aggregates them all:

.. code-block:: sh

  -> POST /aggregate ["/route1", "/route2", "/route3"]

  <- {

         "/route1": answer1,

  <-     "/route2": answer2,

  <-     "/route3": answer3

     }

Why?

----

Mobile networks.

How to install?

---------------

.. code-block:: sh

    $ pip install flask-aggregator

How to setup my application?

----------------------------

.. code-block:: python

   from flask import Flask

   from flask_aggregator import Aggregator

   app = Flask(__name__)

   Aggregator(app=app, endpoint="/batch")

How to aggregate?

-----------------

.. code-block:: sh

   $ python example.py

   [go to another shell]

   $ curl -H "Content-type: application/json" -X POST 127.0.0.1:5000/batch \

                --data-raw '["/hello/world", "/hello/ramnes?question=Sup?"]'

   {

       "/hello/world": "Hello, world!",

       "/hello/ramnes?question=Sup?": "Hello, ramnes! Sup?"

   }

Is it ready for production yet?

-------------------------------

Not really.

As of today, Flask-Aggregator executes the aggregated requests in a

synchronous manner, which makes it only useful if latency is a real issue and

response time is not, and that more than N requests are sent at the same time,

where N is maximum number of concurrent requests on user's client.

Also, it has limitations such has:

* no automatic caching mechanism browser-side, since it uses a POST request

* no header support at all for now, which means no cookie, etag, or whatever

* no other HTTP verb than GET is supported for now

Last but not least, chances are high that a lot of corner cases are not handled.
