Tutorial: Developing in Erlang with Webmachine, ErlyDTL, and Riak
From Alex Popescu’s MyNoSQL blog:
- Part 1
- In Part 1 of the series we covered the basics of getting the development environment up and running. We also looked at how to get a really simple ErlyDTL template rendering
- Part 2
- There are a few reasons this series is targeting this technology stack. One of them is uptime. We’re aiming to build a site that stays up as much as possible. Given that, one of the things that I missed in the previous post was setting up a load balancer. Hence this post will attempt to fill that gap.
- Part 3 In this post we’re going to cover:
- A slight refactor of code structure to support the “standard” approach to building applications in Erlang using OTP.
- Building a small set of modules to talk to Riak.
- Creation of some JSON helper functions for reading and writing data.
- Calling all the way from the Webmachine front-end to Riak to extract data and display it in a browser using ErlyDTL templates.
Erlang is important for anyone building high availability (think telecommunications) systems that can be dynamically reconfigured without taking the systems offline.
