Leakage is a Node.js library for detecting memory leaks by running a function repeatedly and analyzing V8 heap snapshot diffs. It integrates with test runners like Mocha or Tape so leak checks become regular regression tests.

Use cases

• detect memory leaks in a node library
• write regression tests that fail if code leaks memory
• measure memory footprint of repeated operations
• test async code for leaks with iterate.async()
• run leak checks in CI with mocha or tape

When to choose

• you maintain a Node.js library or service and want automated leak detection
• you already use Mocha or Tape and want leak tests in your suite
• you need heap-diff-based evidence that a fix stopped a leak

When to avoid

• you need browser or Deno memory profiling (Node.js only)
• you need continuous production memory monitoring rather than test-time detection
• you need a maintained tool - releases are infrequent and the repo has no license file
