README
Squarespace Template Compiler.
A Java template compiler based on JSON-Template.
License: Apache 2.0 (summary)
Copyright (c) 2014 SQUARESPACE, Inc.
Overview
Squarespace's template language is based on JSON-Template, a minimal declarative template language for Python and JavaScript, heavily influenced by google-ctemplate.
Objectives
The project was started with these objectives:
- Move away from using Node.js for backend template compilation.
- Must meet or exceed performance of the legacy system. The compiler can potentially execute several times for each page view, so it needs to be really fast.
- Improve performance over the legacy system.
- Minimize memory usage. For example, parsing can often create and discard a high number of temporary strings.
- Support additional features for server-side compilation.
- High test coverage.
- Support syntax error recovery.
- Support a template validation mode.
Measured Results
- Average 20x performance increase over previous Node.js + JSON-Template system.
