@robinpath/template

Mustache-like template engine with variable substitution, conditional sections, loops, and simple string interpolation

Why use this module?

The template module lets you:

• Render a Mustache-like template string with variable substitution, sections, and loops
• Read a template from a file and render it with the provided data object
• HTML-escape a string, converting &, <, >, ", and ' to their HTML entity equivalents
• Validate template syntax, checking for unclosed tags, mismatched sections, and other structural errors
• Extract all unique variable and section names used in a template

All functions are callable directly from RobinPath scripts with a simple, consistent API.
