vtha

nano-weight middleware for node.js

inspired by rack, connect and fab.

usage

middleware is defined as a function that accepts status. headers and body parameters and returns an array containing status, headers and a body.

function hello(status, headers, body) {
  return [200, {"Content-Type": "text/plain"}, "hello"]
}

The raw request and response can be accessed via this.env:

function hello(status, headers, body) {
  var req = this.env.req;
  var res = this.env.res;
  return [200, {"Content-Type": "text/plain"}, "hello"]
}

Both parameters and return values are optional. This is useful for intercepting or injecting into the node environment.

function display() {
  var req = this.env.req;
  console.log();
  console.log(req.method, req.url);
  console.log();
}

Middleware is stacked together:

(stack)
  (timer)
  (hello)
  (test);

Each function being passed the [status, headers, body] output of the previous function in the stack
