A skip-list based memory allocator built on top of typed arrays (and node buffers).
It lets you allocate a large, contiguous slab of memory up front and then
free() within that buffer.
It is mostly useful in conjunction with things like mmap.js.
It's developed using design by contract, so you might find the library's own code style a bit unusual, but it doesn't affect usage.
Install via npm.
import Allocator from "malloc"; const heap = new Buffer(1024 * 1024); const allocator = new Allocator(heap); // heap could also be an ArrayBuffer console.log(allocator.inspect()); const input = "Hello World"; const offset = allocator.alloc(Buffer.byteLength(input)); heap.write(input, offset); console.log(allocator.inspect()); console.log(allocator.sizeOf(offset)); console.log('freed', allocator.free(offset), 'bytes');
