buffer-read

Read values from a buffer without maintaining an offset. Useful when you don't want to maintain an offset yourself.

• This module tries to mirror Buffer methods for simplicity.
• Supports reading 64-bit values at 52-bit precision (JavaScript safe integer maximum).

Install

npm install buffer-read

Usage

var Reader = require('buffer-read');
 
var reader = new Reader(new Buffer('6101010172010203', 'hex'));
reader.toString(1); // 'a'
reader.offset += 3; // Skip over 3 bytes
reader.readInt8()   // 0x72
reader.slice(3)     // <Buffer 01 02 03>
 

API

readFloat{BE,LE}(), readDouble{BE,LE}()

Read a floating point number of the specified size and endian format.

toString([encoding], [length])
