process.takeHeapSnapshot creates V8 snapshot
process.takeHeapSnapshot(filePath) takes a V8 heap snapshot and saves it to the specified file path. It returns a boolean indicating whether the snapshot was created successfully.
process.getHeapStatistics returns V8 heap data
process.getHeapStatistics() returns an object with V8 heap statistics reported in Kilobytes. The object contains: totalHeapSize (Integer), totalHeapSizeExecutable (Integer), totalPhysicalSize (Integer), totalAvailableSize (Integer), usedHeapSize (Integer), heapSizeLimit (Integer), mallocedMemory (Integer), peakMallocedMemory (Integer), and doesZapGarbage (boolean).
process.getBlinkMemoryInfo returns rendering memory
process.getBlinkMemoryInfo() returns an object with Blink memory information in Kilobytes: allocated (size of all allocated objects) and total (total allocated space). It can be useful for debugging rendering and DOM related memory issues.
process.getProcessMemoryInfo returns promise with memory stats
process.getProcessMemoryInfo() returns a Promise that resolves with a ProcessMemoryInfo object containing memory usage statistics about the current process in Kilobytes. This API should be called after app ready. On macOS, Chromium does not provide residentSet value because macOS performs in-memory compression; private memory is more representative of actual pre-compression memory usage on macOS.
process.getSystemMemoryInfo returns system-wide memory stats
process.getSystemMemoryInfo() returns an object with system-wide memory statistics in Kilobytes: total (total physical memory available), free (memory not used by applications or disk cache), available (Linux only, kernel estimate for allocation without swapping), fileBacked (macOS only, memory paged to storage), purgeable (macOS only, memory marked as reclaimable), swapTotal (Windows/Linux only, total swap memory), and swapFree (Windows/Linux only, free swap memory).
