princejwesley/extractjs

extractjs is a lightweight JavaScript utility for extracting variable values from a template string and for interpolating data back into that template. It works in Node, Browserify and the browser, letting developers define custom delimiters and value‑transforming extractors to parse strings into objects (e.g., turning “{name}” in a sentence into `{ name: 'John' }`). It’s aimed at developers who need simple, configurable string templating and data‑extraction without pulling in larger libraries.
