# express-partials

Express 3.x Layout & Partial support.

The beloved feature from Express 2.x is back as a middleware!


## Installation

    $ npm install express-partials


## Usage

The simple case:
   
```javascript
var express = require('express')
  , partials = require('express-partials')
  , app = express();

// load the express-partials middleware
app.use(partials());

app.get('/',function(req,res,next){
  res.render('index.ejs') 
  // -> render layout.ejs with index.ejs as `body`.
})

app.get('/no-layout',function(req,res,next){
  res.render('index.ejs',{layout:false})
  // -> only renders index.ejs
})

app.get('/mobile',function(req,res,next){
  res.render('index.ejs',{layout:'mobile'})
  // -> render mobile.ejs with index.ejs as `body`.
})
```

By default express-partials tries to figure the engine out by using the extension of the template. But in special cases an extension can be registered. And this can be done in a few ways:

```javascript
// a function
partials.register('.j',require('jade').render); 

// module (or object with a .render() function)
partials.register('.j',require('jade')); 

// string (= require(str))
partials.register('.j','jade'); 
```

For an example on how to use partials in the first place I'd recommend you checking out the [Express 2.x ejs example](https://github.com/visionmedia/express/tree/2.x/examples/ejs).

## Template Support

Any synchronous template engine should work fine. But check out the [tests](./test/test.partials.register.js) for a few engines tested.


## TODO

 - Async template engines?


## Running Tests

To run the test suite first install dependencies with the following command within the repo:

    $ npm install

then run the tests:

    $ npm test
