Masala Parser is an Open source javascript library to create your own parsers. You won't need theoretical bases on languages for many usages. Masala Parser shines for simplicity, variations and maintainability of your parsers.

There are two kind of people on Earth. Those who have made a compiler, and the others. Masala Parser is a killer to be part of that first category.

I’m launching Masala Parser v2, a modern refresh of a 10-year-old open source parser combinator library for JavaScript and TypeScript.

Masala Parser is inspired by Haskell’s Parsec and lets you describe parsers in plain JS/TS code instead of wrestling with huge regexes or a separate grammar file.

With Masala you can:

Build type-safe custom parsers
Design small DSLs and config languages
Replace brittle regexp chains with readable, tested code

It’s plain JavaScript with strong TypeScript support, works in Node and the browser, and has been battle-tested over the years.
