The Tech

We're building Style.com to be the most sophisticated ecommerce platform in the world. We use the latest technology, not just because it's fun (although it is!), but because the best tools help us put together the best team and deliver a great experience for our customers worldwide.

Here's a taste of the tech you'll be working with:

• Single-page frontend applications based on a ClojureScript/Reagent/React stack
• Neural net-driven recommendation and search systems in Clojure
• Automatic curation tools using tag hierarchies in Datomic
• Containerised deployments on AWS/Docker/Kubernetes

Atom Clojure Setup

This describes how I setup Atom for an ideal Clojure development workflow. This fixes indentation on newlines, handles parentheses, etc. The keybinding settings for enter (in keymap.cson) are important to get proper newlines with indentation at the right level. There are other helpers in init.coffee and keymap.cson that are useful for cutting, copying, pasting, deleting, and indenting Lisp expressions.

Install Atom

Download Atom

The Atom documentation is excellent. It's highly worth reading the flight manual.

Text markup and structure

• So many light markup formats to consider
  • Markdown
  • Textile
  • reStructuredText
  • Asciidoc
  • Most compile to HTML, PDF, DocBook
• Get handy with PanDoc (but man, the haskell bootstrapping is a pain)
