README

util Build Status

Node.js's util module for all engines.

This implements the Node.js util module for environments that do not have it, like browsers.

Install

git

git clone https://iramiller.com/src/js/util/.git util

npm

npm install @guld/util

Usage

import util from '../util/util.js')
import EventEmitter from '../events/events.js')

function MyClass() { EventEmitter.call(this) }
util.inherits(MyClass, EventEmitter)

Browser Support

The util module uses ES6 features. Load it like any module with a static import import 'util.js'.

API

See the Node.js util docs. util currently supports the Node 8 LTS API. However, some of the methods are outdated. The inspect and format methods included in this module are a lot more simple and barebones than the ones in Node.js.

Contributing

PRs are very welcome! The main way to contribute to util is by porting features, bugfixes and tests from Node.js. Ideally, code contributions to this module are copy-pasted from Node.js and transpiled to ES5, rather than reimplemented from scratch. Matching the Node.js code as closely as possible makes maintenance simpler when new changes land in Node.js. This module intends to provide exactly the same API as Node.js, so features that are not available in the core util module will not be accepted. Feature requests should instead be directed at nodejs/node and will be added to this module once they are implemented in Node.js.

If there is a difference in behaviour between Node.js's util module and this module, please open an issue!
