WebSocket buffer utils

Package Exports

  • bufferutil

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bufferutil) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

bufferutil

Buffer utils is one of the modules that makes ws fast. It's optimized for certain buffer based operations such as merging buffers, generating WebSocket masks and unmasking.

As the module consists of binary components, it should be used an optionalDependency so when installation fails, it doesn't halt the installation of your module. There are fallback files available in this repository. See fallback.js for the suggest fallback implementation if installation fails.

Installation

npm install bufferutil

API

In all examples we assume that you've already required the BufferUtil as followed:

'use strict';

var bu = require('bufferutil').BufferUtil;

The module exposes 3 different functions:

merge

Merge multiple buffers in the first supplied buffer argument:

bu.merge(buffer, [buffer1, buffer2]);

This merges buffer1 and buffer2 which are in an array into buffer.

mask

Apply a WebSocket mask on the given data.

bu.mask(buffer, mask);

unmask

Remove a WebSocket mask on the given data.;w

bu.unmask(buffer, mask);
