Shameless self-promotion: I wrote a JSON parser for node.js that specifically solves this problem of parsing deeply-nested and/or huge JSON payloads. https://www.npmjs.com/package/bfj https://www.npmjs.com/package/bfj It's entirely asynchronous, yielding frequently to avoid monopolising the event loop. And it uses a fixed-length buffer so it never exhausts available memory. The tradeoff is that it's slow. But afaik it parses JSON payloads of any size and any depth.
