dataview2

Efficient DataView for isomorphic libraries

Installation

npm:

npm install dataview2

API

• DataView2(buffer: Buffer|ArrayBuffer): BufferDataView|DataView
  • node.js: returns an instance of BufferDataView
  • browser: returns an instance of DataView
• Buffer2(n: size): Buffer|ArrayBuufer
  • node.js: return an instance of Buffer
  • browser: return an instance of ArrayBuffer

Examples

use Buffer in the Node.js

var buffer = new Buffer2(4); // → Buffer
var view = new DataView2(buffer); // → BufferDataView
 
// 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
 
console.log(view.buffer instanceof Buffer);
// → true

use ArrayBuffer in the browser

var buffer new Buffer2(4); // → ArrayBuffer
var view = new DataView2(buffer); // → DataView
 
// set a "float" in the data view
view.setFloat32(0, 1337.1234, true);
 
console.log(view.buffer instanceof ArrayBuffer);
// → true
 
// ensure that the original ArrayBuffer was modified
console.log(new Float32Array(buffer)[0]);
// → 1337.1234130859375
