# middleware-object-hooks

[![Build Status](https://travis-ci.org/lightsofapollo/middleware-object-hooks.png?branch=master)](https://travis-ci.org/lightsofapollo/middleware-object-hooks)

Middleware(ish) hooks based on "methods" in objects.

## Usage

(Also see [examples/](examples/))

```js

var middleware = require('middleware-object-hooks');

middlware.use({

  start: function(value) {

    value.calls = value.calls || 0;

    return value;

  }

});

middlware.use({

  start: function(value) {

    value.calls++;

  }  

});

middlware.use({

  start: function() {

    return new Promise(function(accept, reject) {

      // do some magic then accept / reject

    });

  }

});

middlware.run(

  'start', // method in the middleware

  {

    // passed to the method in the middleware  

  }

).then(

  function(value) {

  },

  function(err) {

  }

);

```

## Notes

 - Middleware methods are invoked within the context of their object

 - Multiple values may be passed to run (or none at all)

 - Each result is passed directly to the next middleware so its possible

   to both mutate the value (if its an object) and entirely replace it.
