The Parser class is a streaming JSON parser that processes data in chunks via the .write(buffer) method. To use it, you must extend the Parser class and override the onValue(value) method to receive parsed JSON values as they are completed.
Because it is a streaming parser, it maintains internal state across multiple .write() calls, making it suitable for large JSON datasets that do not fit in memory.
const Parser = require('./jsonparse');
class MyParser extends Parser {
onValue(value) {
console.log('Parsed value:', value);
}
}
const parser = new MyParser();
// Feed chunks of data (Buffers or strings)
parser.write(Buffer.from('{"key": "value", '));
parser.write(Buffer.from('
