Sequentially Allocatable and Deallocatable Resource Counter written in JavaScript. It is useful for tracking resource usage such as inodes and file descriptors. The resource counter is backed by a new lazy recursive perfectly balanced dynamically growing and shrinking bitmap tree data structure. This allows logarithmic allocation and deallocation performance. It's memory usage is better than the alternative deallocated stack + counter method.
npm install --save 'resource-counter';import Counter from 'resource-counter';
let c = new Counter;
let first = c.allocate();
let second = c.allocate();
let third = c.allocate();
let fourth = c.allocate();
c.deallocate(second);
c.deallocate(third);
console.log(c.allocate() === second);
console.log(c.allocate() === third);
console.log(c.allocate() === (fourth + 1));Documentation is located in the doc folder. You can also view the rendered HTML.
To build this package for release:
npm run build
It will run tests, generate documentation and output multiple targets. One for browsers and one for nodejs. See rollup.config.js to see the target specification.
If your bundler is aware of the module field in package.json, you'll get the ES6 module directly.
Once you've updated the package run this:
npm version <update_type>
npm publish
