The Ruby ecosystem is pretty awesome when it comes to developing or
consuming HTTP APIs. On the publishing front, the Rails framework is
an attractive option because it supports publishing what are popularly
(but inaccurately) referred to as 'RESTful' APIs quickly and
effortlessly. On the consumer side, the Ruby ecosystem provides
several very fluent and powerful libraries that make it easy to
consume HTTP based APIs.
Since a significant proportion of projects today require that APIs be
both published and consumed, many of them wind up choosing Ruby as a
platform for the reasons mentioned above. This talk is targeted at
folks that are currently on such projects, or anticipate being on such
projects in the future.
We will cover:
Consuming HTTP APIs:
1) The basics of making HTTP calls with Ruby
2) The strengths and weaknesses of Ruby's Net::HTTP across 1.8, 1.9
and JRuby (possibly Rubinius if we have the time to do research)
3) Popular HTTP libraries that either make it easier to do HTTP by
providing better APIs, make it faster by using libCurl or both
4) Different approaches to deserializing popular encoding formats such
as XML and JSON and the pitfalls thereof
Producing HTTP APIs using Rails:
1) The basics of REST
2) What Rails gives you out of the box - content-type negotiation,
deserialization etc. and the limitations thereof
3) What Rails fails to give you out of the box - hypermedia controls etc.
4) What Rails does wrong - wrong PUT semantics, no support for PATCH,
error handling results in responses that violate the clients Accepts
header constraints etc.
4) How one can achieve Level 2 on the Richardson Maturity Model of
REST using Rails
5) Writing tests for all of this
At the end of this, our audience will understand how you can both
consume and produce HTTP APIs in the Ruby ecosystem. They will also
have a clear idea of what the limitations of such systems are and what
the can do to work around the limitations.
The Ruby community has driven a lot of technical innovation in deployment and configuration management over the last few years, and so the idea of delivering high-quality software rapidly should be familiar to most of us. But although our tools are state-of-the-art, getting them to work together properly can be surprisingly frustrating. In this talk, I'll explain how to implement a high-quality rapid build and deploy process using standard CI tools, Bundler, RVM, and Capistrano. I'll also discuss how to coach your developers, QAs, and client to be "production-ready, any time."
Discussing language constructs with fellow developers in the context of solving a particular problem is something we do routinely. While most such conversations are productive and useful, a fair portion degenerate into angry brawls. A pattern we've observed in the latter situation is that a surprising number of times the argument is that "Why shouldn't I use language feature X to achieve objective Y- after all, the language supports X."
In this talk Aakash and Niranjan walk through a few features of the Ruby language which when used wisely allows programmers to solve problems elegantly but if they are used without caution can lead to bad code.
