fix-buffer

Fixes Issues where NodeJS Buffers are Accidentally Converted into Simple Objects

background

Sometimes when developing packages that run on the browser and in NodeJS, you can run into weird edge cases where a Buffer is converted into a simple object without any of its functions and Buffer.isBuffer fails. This package undoes that weird failure and reconverts a simple object that looks like a buffer into a Buffer.

install

npm install fix-buffer

usage

If you pass a broken buffer into fixBuffer, it re-converts the input into a buffer. If you pass in something else like a random string, it just returns what you passed in.

const fixBuffer = require("fix-buffer");

const brokenBuffer = {
    type: 'Buffer',
    data: [
      59, 48, 76,  7, 70, 67,
      39, 71, 13, 21, 52, 57
    ]
};
Buffer.isBuffer(brokenBuffer) // false

const fixedBuffer = fixBuffer(brokenBuffer);

Buffer.isBuffer(fixedBuffer) // true
