JQuery Templates Strawman
Implements the jQuery Templates Strawman,
test directory contains HTML benchmarks and a conformance suite.
This project actually contains several semi-independent implementations.
The reference implementation (in
src/ref.js) is a simple, inefficient, clear implementation of the spec.
The strappend implementation (in
src/impl.js) is a small, fast, implementation that should conform
with the reference implementation in every detail, but is more complicated due to speed/size constraints.
The other files in src are common supporting code for the two implementations.
If the strappend implementation differs from the reference implementation then strappend is wrong. If the reference implementation is behaving differently than it should, then there is an error in the spec.

Building And Running Tests
The source files under
js/ are written to minimize dependencies on jQuery and to minify well. They declare
private helper functions globally.
|↳ jquery-templates-reference.js||A simple, slow reference implementation that mirrors the spec.|
|↳ jquery-templates-strappend.js||An efficient implementation that provides good error messages.|
|↳ jquery-templates-compiled.js||An aggressively minimized version of strappend that does not include error reporting code.|
The efficient strappend implementation functions in 3 modes:
- Debug: jQuery templates are compiled as-needed in the client with rich error checks and error messages.
- Production: jQuery templates are compiled as-needed in the client with
DEBUG = falsewhich removes most of the error checks and error messages to minimize download size and startup time.
Normally to use jQuery templates, you ship code like the below:
which includes jQuery templates support code including the template parser and compiler and a template definition.
At load time, the jQuery templates code will parse and compile templates as needed.
Debugging checks are not useful after you've run your unittests and you know your templates are syntactically valid. The debugging checks take a significant amount of space; nice error messages don't compress well.
The compiled version of the strappend includes the full template parser and runtime, but without error checks that are usually redundant in production.
So in pre-compiled mode, the example above would pre-compile to something like
