    buffer-expand

    npm Travis branch

    Expand a buffer to a specified length. If the buffer is smaller than the specified length, the remaining space is filled with random bytes. A 32-bit Unsigned Big-Endian Integer containing the length of the data is always prepended to the buffer.

    Installation

    npm install buffer-expand
    

    Usage

    const size = 25
    const { expand, shrink } = require('buffer-expand')(size)
     
    const data = Buffer.from('Hello World!')
    const newData = expand(data)
    console.log(data, newData)
    // Prints:
    // <Buffer 48 65 6c 6c 6f 20 57 6f 72 6c 64 21>
    // <Buffer 00 00 00 0c 48 65 6c 6c 6f 20 57 6f 72 6c 64 21 91 5c d3 2f>
    assert(newData.length === size)
    assert(shrink(newData).equals(data))
