const formatMemoryUsage = (data) => `${Math.round(data / 1024 / 1024 * 100) / 100} MB`;

const memoryData = process.memoryUsage();

const memoryUsage = {
  rss: `${formatMemoryUsage(memoryData.rss)} -> Resident Set Size - total memory allocated for the process execution`,
  heapTotal: `${formatMemoryUsage(memoryData.heapTotal)} -> total size of the allocated heap`,
  heapUsed: `${formatMemoryUsage(memoryData.heapUsed)} -> actual memory used during the execution`,
  external: `${formatMemoryUsage(memoryData.external)} -> V8 external memory`,
};

console.log(memoryUsage);

node js memory usage

Comment

import os from 'node:os';

const bytesToMega = (bytes: number) => Math.round((bytes / 1024 / 1024) * 100) / 100;

const getMemoryUse = () => {
	const { heapTotal, heapUsed } = process.memoryUsage();
	const percentUsed = ((heapUsed * 100) / heapTotal).toFixed(2);

	return `${bytesToMega(heapUsed)}MB / ${bytesToMega(heapTotal)}MB (${percentUsed}%)`;
};

export default {
	logToStream(stream: NodeJS.WritableStream, interval: number = 1000) {
		const id = setInterval(() => {
			stream.write(getMemoryUse() + os.EOL);
		}, interval);

		const closeInterval = () => {
			clearInterval(id);
			process.exit(0);
		};
		process.on('SIGINT', closeInterval);
		process.on('SIGKILL', closeInterval);
	},

	getMemoryUse,
};
