process

require('process'); just like any other module.

Works in node.js and browsers via the browser.js shim provided with the module.

package manager notes

If you are writing a bundler to package modules for client side use, make sure you use the browser field hint in package.json.

See https://gist.github.com/4339901 for details.

The browserify module will properly handle this field when bundling your files.
