co-ware Build Status

Ware inspired, easily create your own middleware layer using generators via co.

Examples

var ware = require('..');
var w = ware()
  .use(function *(next) {
    this.x = 'hello';
    yield next;
  })
  .use(function *(next) {
    this.y = 'world';
    yield next;
  })
  .use(function *(next) {
    yield next;
  });

w.run({}, {}, function *() {
  console.log(this.x, this.y);
});

Print the arguments of input.

var ware = require('..');
var w = ware()
  .use(function *(next) {
    console.log(this.input); // 1, 2, 3
    yield next;
  });

w.run(1, 2, 3);

Handles error.

var ware = require('..');
var w = ware()
  .use(function *(next) {
    if ('42' != this.input[0].life) throw new Error();
    yield next;
  })
  .use(function *(next) {
    console.log('yes!');
  })
  .on('error', function (err) {
    console.log('no!');
  });

w.run({ life: '41' }); // "no!"
w.run({ life: '42' }); // "yes!"

API
