leak.js

Native NodeJS library for leaking memory.

Usage

leak(bytes)

Returns one of:

• undefined on error
• true if the memory was leaked successfully
• false if the memory couldn't be allocated

For example:

const leak = require('leak.js');
leak(2 ** 30) // Leaks 1 GiB of memory

Leaking larger amounts of memory takes longer. If you want to leak a large amount of memory without blocking the main thread, I recommend using a worker thread.

FAQ

Why?

Because pee.js could be improved. It has a few shortcomings:

• Allocation is not optimized.
• Allocated memory is still accesible under global.toilet, so it isn't truly "leaked".
• It's not actually running malloc(), which is no fun.

leak.js is about 10-15% faster than pee.js at leaking memory, and makes leaked memory truly unfreeable.

How can I free leaked memory?

Simply call process.exit()
