City of Los Angeles Pattern Library
About Pattern Lab
The PHP version of Pattern Lab is, at its core, a static site generator. It combines platform-agnostic assets, like the Mustache-based patterns and the JavaScript-based viewer, with a PHP-based "builder" that transforms and dynamically builds the Pattern Lab site. By making it a static site generator, Pattern Lab strongly separates patterns, data, and presentation from build logic.

Creating & Working With Dynamic Data for a Pattern
The PHP version of Pattern Lab utilizes Mustache as the template language for patterns. In addition to allowing for the inclusion of one pattern within another it also gives pattern developers the ability to include variables. This means that attributes like image sources can be centralized in one file for easy modification across one or more patterns. The PHP version of Pattern Lab uses a JSON file, source/_data/data.json
, to centralize many of these attributes.
