Andrew Curioso - Developing an API
I would like to present a talk on the importance of APIs (particular open ones) and how to implement a RESTful API quickly and easily in CakePHP. The talk will start with a brief overview on why APIs are so important. I will touch on multiple benefits including the two largest benefits: - Making development for multiple target platforms easier and cheaper ( Adobe Air / Facebook / Ajax / iPhone / iPad / Blackberry / etc. ). - Becoming a platform and having the option of letting third parties develop for it. To reinforce those point there will be a slide on "sites you may have heard of" that have open RESTful APIs. Twitter, Facebook, Yahoo!, and Google anyone? The presentation will dive into code. But only after a brief explanation of what REST is that includes the definitions of verbs (in the context of REST), URIs, mime types, and response codes. Things will move quickly after that. A simple controller will be built using Bake and mapped as a resource. Followed by a quick test using cURL to prove it works. Emphasis will be put on the speed of development in CakePHP (as if the audience needs to be sold on that). Then onto create a Json view for the data. This section will draw on my experiences and include some best practices for API development. If that weren't cool enough -- at this point it is a fully working API -- I will show a quick XML and Yaml view into the data to show off some of Cake's core strengths. Just for the "wow effect" a PDF (the output of another view) will be shown before moving on. At this point it will be nearing the third quarter of the presentation. I will briefly show an Adobe Air application accessing the data then quickly flash the code and screen shots for an iPad and a Facebook application. I will then touch on what's still needs to be done before deploying to a production environment: - Context sensitive error handling (ex: Json views should output errors in Json format). - User authentication (oAuth and Digest Authentication will be defined here). This is also an appropriate time to list the alternatives to REST. Most notably RPC based APIs. I will briefly go over where to find the source code for all the examples and the location of some Bakery articles for further reading. The presentation will then be concluded with a quick case study / personal story. The floor will then be opened for some questions if there is time. The presentation is ideal for one of the hour time slots however it can be done in 45 minutes if need-be.
