JLTO

JLTO (Jinja Like Templates Optimizer) is a Node.js tool for minifying and optimizing templates from Jinja-like engines (Nunjucks, Twig.js, LiquidNode, etc.). As of v1.5.4, it strips whitespace, removes comments, and optionally minifies HTML via html-minifier-next. It supports custom delimiters and engine-specific syntax. Released under MIT, it is a niche alternative to build-tool plugins, offering programmatic optimization via optimizeString(). It is actively maintained with frequent patch updates.
