Nuxt currently depends on connect, a lightweight middleware framework for Node. connect currently has 10 dependencies, some of which haven't had updates in a long time. All are still written in ES5-style JavaScript and some still try to specifically address Node 0.8 shortcomings.
- connect@3.6.6
- debug@2.6.9
- finalhandler@1.1.0
- encodeurl@1.0.2
- escape-html@1.0.3
- on-finished@2.3.0
- ee-first@1.1.1
- statuses@1.4.0
- unpipe@1.0.0
- parseurl@1.3.2
- utils-merge@1.0.1
@nuxt/metal is an attempt to provide a fully backwards-compatible rewrite of connect in modern JavaScript, with added support for async middleware and a restructured codebase with many simplifications, cleanups and idiomatic rewrites. All without compromising performance, if not improving it slightly.

autocannon -c 100 -d 40 -p 10 localhost:3000This module is largely based on the work of TJ Holowaychuk, Douglas Christopher Wilson, Jonathan Ong and the awesome people at Joyent. This package is simply a massive restructuring of all original code, with only a few minor pieces removed and improved upon.
