Easily create your own middleware layer.

ware

Easily create your own middleware layer.

Node:

$ npm install ware

Component:

$ component install segmentio/ware

Duo:

var ware = require('segmentio/ware');
var ware = require('ware');
var middleware = ware()
  .use(function (reqresnext) {
    res.x = 'hello';
    next();
  })
  .use(function (reqresnext) {
    res.y = 'world';
    next();
  });
 
middleware.run({}, {}, function (errreqres) {
  res.x; // "hello" 
  res.y; // "world" 
});

Give it any number of arguments:

var ware = require('ware');
var middleware = ware()
  .use(function (abcnext) {
    console.log(a, b, c);
    next();
  })
 
middleware.run(1, 2, 3); // 1, 2, 3 

Supports generators (on the server):

var ware = require('ware');
var middleware = ware()
  .use(function (obj) {
    obj.url = 'http://google.com';
  })
  .use(function *(obj) {
    obj.src = yield http.get(obj.url);
  })
 
middleware.run({ url: 'http://facebook.com' }, function(errobj) {
  if (err) throw err;
  obj.src // "obj.url" source 
});

Create a new list of middleware.

Push a middleware fn onto the list. fn can be a synchronous, asynchronous, or generator function. fn can also be an array of functions or an instance of Ware.

Runs the middleware functions with input... and optionally calls callback(err, input...).
