const session = new Session();
const fd = fs.openSync('profile.heapsnapshot', 'w');
session.connect();
session.on('HeapProfiler.addHeapSnapshotChunk', (m) => {
fs.writeSync(fd, m.params.chunk);
});
const result = await session.post('HeapProfiler.takeHeapSnapshot', null);
console.log('HeapProfiler.takeHeapSnapshot done:', result);
session.disconnect();
fs.closeSync(fd);
