documentation

The module.exports a constructor

var Manifold = require('manifold');

that takes no arguments

var manifold = new Manifold();

In all the following node refers to the object mapping path to object.

manifold.set([path, props])

set a path to regex mapping for an object

arguments

• path type string

• props type function or plainObject

• when is a function it will be assigned to the props.handle

• when is a plainObject, all option properties are passed first to a parser if there is one and if not, that property is cloned and assigned to the node props

returns this

The path is taken as a regular expression using the parth module, which uses the usual conventions on for path to regexp parsing. So you know... interesting things can happen.

samples

manifold.set('get /user/:page(\\d+)', function getUserPage(){
  // do stuff
});
 
manifold.get('get /user/10');
// =>
{
  notFound: false,
  path: 'get /user/10',
  url: '/user/10',
  match: 'get /user/10',
  params: { _: [ 'page' ], page: '10' },
  handle: [Function: getUserPage]
}
 

manifold.get([path, options, mod])

get an object matching the given path, clone it if necessary

arguments

• path, optional, type string
• options, optional, type object with all extra information
• mod, type object. If is a:
  • plainObject with property ref, the node found will not be cloned
  • regular expression, are the props to skip while cloning

returns the object (cloned/by reference) node found

In addition, if the node has a parent it will inherit its properties while cloning.

sample

manifold.set('get /user/:page', {
  parent: 'get /user',
  handle: function getUserPage(){};
});
 
manifold.set('get /user', {
  picture: function getPicture(){
    // fetch that thing
  },
  render: function markup(){
    // you know, some markup
  }
});
 
manifold.get('get /user/10'); // =>
{
  notFound: false,
  path: 'get /user/10',
  url: '/user/10',
  match: 'get /user/10',
  params: { _: [ 'page' ], page: '10' },
  handle: [Function: getUserPage],
  picture: [Function: getPicture],
  render: [Function: markup]
}

instance properties

• manifold.regex: regexes are stored here
• manifold.store: key value store with all of the nodes stored

why

I Need it for the runtime module ;)

The project name is an homage to the concept of manifold. Beautiful creature of Math and Physics thought. BUT, this can't be considered the real thing. That is: this is not a manifold. I'd wish!

install

With npm

npm install manifold --save
