Chevrotain

Introduction

Chevrotain is a blazing fast and feature rich Parser Building Toolkit for JavaScript. It can be used to build parsers/compilers/interpreters for various use cases ranging from simple configuration files, to full fledged programing languages.

A more in depth description of Chevrotain can be found in this great article on: Parsing in JavaScript: Tools and Libraries.

It is important to note that Chevrotain is NOT a parser generator. It solves the same kind of problems as a parser generator, just without any code generation. Chevrotain Grammars are pure code which can be created/debugged/edited as any other pure code without requiring any new tools or processes.
