buffer-shims

functions to make sure the new buffer methods work in older browsers.

var bufferShim = require('buffer-shims');
bufferShim.from('foo');
bufferShim.alloc(9, 'cafeface', 'hex');
bufferShim.allocUnsafe(15);
bufferShim.allocUnsafeSlow(21);

should just use the original in newer nodes and on older nodes uses fallbacks.

Known Issues

• this does not patch the buffer object, only the constructor stuff
• it's actually a polyfill
