jay v0.0.8

jay

The hottest frontend wrapper around. Inspired by browserify, jay gives you a browser-side require() for javascript, css, & templates.

Jay allows you to componentize your frontend, breaking it up into a structure that makes the most sense to you.

Jay was originally built for use with express, but may be extended to other http servers.

Installation

npm install jay

Example

kanye.js

/**
 * Module dependencies
 */

var $ = require('jquery');

/**
 * Require `Kanye` styling
 */

require('./kanye.css')

/**
 * Export `Kanye`
 */

var Kanye = module.exports = function() { ... };

/**
 * Add a (mustache) template
 */

Kanye.prototype.template = require('./kanye.mu');

/**
 * Render `Kanye` template
 */
 
Kanye.prototype.render = function(locals) {
  document.body.appendChild(locals);
};

jay.js

/**
 * Module dependencies
 */

var Kanye = require('./kanye');

var Jay = module.exports = function() { ... };

Jay.prototype.nextSong = function() {
  if(this.isTired()) {
    kanye = new Kanye();
    kanye.render({ sunglasses : 'Ray Ban', chains : true });
  }
}

Using express

var express = require('express'),
    jay = require('../../'),
    cons = require('consolidate'),
    app = express();

/**
 * Jay Configuration
 */

jay.root(__dirname)
   .build(join(__dirname, 'build'))
   .include('hogan.js', '/vendor/hogan.js');

/**
 * Configuration
 */

app.configure(function() {
  app.set('view engine', 'html');
  app.use(express['static'](join(__dirname, 'build')));
});

app.configure('development', function() {
  // Jay wraps around the templating engine,
  // should only be wrapped during development
  app.engine('html', jay(cons.hogan));
});

app.configure('production', function() {
  app.engine('html', cons.hogan);
});

...

app.listen(8080);

API

root(dir)

Required. The root directory for jay. Absolute paths map to the root, for example /models/user.js maps to $ROOT/models/user.js

jay.root(__dirname);

build(dir)

Where the build files are outputted. Defaults to $ROOT/build.

jay.build(path.join(__dirname, 'out'));

alias(to, from)

Alias an asset that has already been required by the view. Useful for creating shorter, perhaps more familiar routes.

Note: from is relative to jay's root, which may not be the same as the relative path from your server.

jay.alias('jquery', '/vendor/jquery.js')
   .alias('underscore', '/vendor/underscore.js')

include(alias, asset)

Includes an asset that is not currently being required by the view. Useful for adding client-side templating libraries (hogan.js, jade.js) without requiring them explicitly.

If alias is used, it will also create an alias to that included asset.

Note: asset is relative to jay's root, which may not be the same as the relative path from your server.

jay.include('hogan.js', '/vendor/hogan.js');

cache(dir)

Jay uses deputy for caching the require dependency tree. dir specifies where the cache is stored. Defaults to $HOME/.jay/cache.json.

jay.cache('.jay/app.json')

To turn off caching:

jay.cache(false);

jay(function(path, locals, fn))

Jay works with any supported express templating engine. You can even use your own templating language with jay as long as you follow the express engine function signature.

var supersizer = function(path, locals, fn) {
  var str = fs.readFileSync(path, 'utf8');
  str = str.replace(/h(\d)/g, function(m, p) {
    p = (p > 1) ? p : 2;
    return 'h' + --p;
  });
  return fn(null, str);
};

app.engine('html', jay(supersizer));

create()

Create a new instance of jay.

var jay = require('jay'),
    jay2 = jay.create();
