const used = process.memoryUsage().heapUsed / 1024 / 1024;
console.log(`The script uses approximately ${Math.round(used * 100) / 100} MB`);

node.js check memory usage

Comment

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);
