Browser-friendly inheritance fully compatible with standard node.js inherits()

A stream that emits multiple other streams one after another.

Use node's fs.realpath, but fall back to the JS implementation if the native one fails

Returns true if a number or string value is a finite number. Useful for regex matches, parsing, user input, etc.

Allows users to use generators in order to write common functions that can be both sync or async.

Implements performance.now (based on process.hrtime).

Memoize the results of a call to the RegExp constructor, avoiding repetitious runtime compilation of the same string and options, resulting in surprising performance improvements.

Lightweight Node.js version sniffing/comparison

Normalize slashes in a file path to be posix/unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes, unless disabled.

Require constants across node and the browser

safely create multiple ReadStream or WriteStream objects from the same file descriptor

Color your terminal using CSS/hex color codes

Deprecate all the things

set blocking stdio and stderr ensuring that terminal output does not truncate

Convert a file: URI to a file path

A super tiny library to make input type='range' sliders work better on touch devices

Combine an array of streams into a single duplex stream using pump and duplexify
