buffer-dataview

Minimal DataView implementation that works with Node.js Buffers

This module provides a very minimal DataView implementation. Node.js already comes with a DataView implementation, but it only works with ArrayBuffer instances, and not Node's preferred Buffer type. This is mostly useful when re-using previously written code which interacts with DataView instances rather than Node.js Buffers.

The DataView instances simply proxy the invoked instance method to the equivalent Buffer API call.

Note that the buffer property of the DataView instance is the Node.js Buffer instance, and not a converted ArrayBuffer or something else like that. There's no copying that happens here, it's just a "view"...

Installation

Install with npm:

$ npm install buffer-dataview

Example

var DataView = require('buffer-dataview');

var buffer = new Buffer(4);
var view = new DataView(buffer);

// set a "float" in the data view
view.setFloat32(0, 1337.1234, true);

// ensure that the original Buffer was modified
console.log(buffer.readFloatLE(0));
// → 1337.1234130859375
