How to request the Garbage Collector in node.js to run with Node.js?

To request the Garbage Collector in node.js to run with Node.js, we call the global.gc method.

For instance, we write

try {
  global?.gc?.();
} catch (e) {
  console.log("`node --expose-gc index.js`");
  process.exit();
}

to call global.gc to request the garbage collector if it’s available.

We make the garbage collection available with the --expose-gc flag.
