Hello to the World in 8 Web Frameworks (Micro, Batteries Included & Async)

A Phileas Fogg inspired tour of 8 frameworks "Had he programmed? It was likely, for no one seemed to know web frameworks more familiarly; there was no framework so obscure that he did not appear to have an intimate acquaintance with it. He must have developed in everything, at least in the spirit."

Introduction to OpenAPI Specification

Open API Specification is a machine and human readable way to describe APIs. From these specs we can generate documentation, create libraries, and ensure that our users know exactly what to expect from our APIs. This talk shows you around OAS from the beginning, showing how to create the specs and recommending some tools to help the process. Once you have the spec, things get interesting and this talk will showcase some of the things that you can offer once your API is described in this way. This session is recommended for writers looking to become more API-savvy and API engineers wanting to make their APIs more useful to their users.

Reduce, Reuse, Recycle - Persisting WebSocket connections with SharedWorkers

When using WebSockets to communicate between your server and the client every new browser context–tab, window, iframe, and so on–is likely to create another WebSocket connection. All these open connections can quickly take a toll on your server resources, or if you’re using a PaaS which charges for each connection, it could quickly add up to a big bill. In this talk, we’ll look at how you can use SharedWorkers to create a single persistent WebSocket which can be used by every browser context to communicate with your Django Channels WebSocket server
