My JSON file is very large to do this in memory (≈ 500MB) and there will be more than one files that I should read concurrently. Is there any way that I can do this in Node.js ? (with or without any external libraries)

const searchStream = (path, text = '') => new Promise((resolve, reject) => {
  const inStream = fs.createReadStream(path);
  const outStream = new Stream();
  const rl = readline.createInterface(inStream, outStream);
  const result = [];
  let count = 0;
  const regEx = new RegExp(text, 'i');
  rl.on('line', (line) => {
    if (line && line.search(regEx) >= 0) {
      count++;
      result.push(line);
    }
  });
  rl.on('close', () => {
    resolve({
      result,
      count,
    });
  });
  rl.on('error', (err) => {
    reject(err);
  });
});
