It is impossible to parse 1gb JSON file with native node.js primitives.
Just a streaming parser, nothing really fancy. The only difference between this parser and the others is that it can skip data that nested too deeply.
npm install json-depth-stream
const DepthStream = ;const file = ;const json = 1 /* desired depth */;json;file;
const json = 1;const q = json;q;q;processstdin;
const json = 1;processstdin;// `split` even is emitted when parser enters new object value/array element// `index` is local to `chunk`.json;
Around 78mb/s for JSON with many object keys, faster for array-like JSONs:
$ node benchmark/throughput.jsThroughput: 78.44 mb/s
