Jade is a high performance template engine heavily influenced by [Haml](http://haml-lang.com)
|
||
|
|
and implemented with JavaScript for [node](http://nodejs.org) and browsers. For bug reports,
|
||
|
|
feature requests and questions, [open an issue](https://github.com/jadejs/jade/issues/new).

## Installation
|
||
|
|
|
||
|
|
via npm:
|
||
|
|
|

## Syntax
|
||
|
|
|
||
|
|
Jade is a clean, whitespace sensitive syntax for writing html. Here is a simple example:
|
||
|
|
|
||
|
|
```jade
|
||
|
|
doctype html
|
||
|
|
html(lang="en")
|
||
|
|
head
|
||
|
|
title= pageTitle
|
||
|
|
script(type='text/javascript').
|
||
|
|
if (foo) bar(1 + 5)
|
||
|
|
body
|
||
|
|

|
|
|

The official [jade tutorial](http://jade-lang.com/tutorial/) is a great place to start. While that (and the syntax documentation) is being finished, you can view some of the old documentation [here](https://github.com/jadejs/jade/blob/master/jade.md) and [here](https://github.com/jadejs/jade/blob/master/jade-language.md)

## API
|
||
|
|
|
||
|
|
For full API, see [jade-lang.com/api](http://jade-lang.com/api/)
|
||
|
|
|
||
|
|
```js
|
||
|
|
var jade = require('jade');
|
||
|
|
|
||
|
|
// compile
|
||
|
|
var fn = jade.compile('string of jade', options);
|
||
|
|
var html = fn(locals);
|
||
|
|
|
||
|
|
// render
|
||
|
|
var html = jade.render('string of jade', merge(options, locals));
|
||
|
|
|
||
|
|
// renderFile
|
||
|
|
var html = jade.renderFile('filename.jade', merge(options, locals));
|
||
|
|
```
|
||
|
|
|
||
|
|
### Options
|
||
|
|
|
||
|
|
- `filename` Used in exceptions, and required when using includes
|
||
|
|
- `compileDebug` When `false` no debug instrumentation is compiled
|
||
|
|
- `pretty` Add pretty-indentation whitespace to output _(false by default)_
|
||
|
|
|
||
|
|
## Browser Support
|
||
|
|
|
||
|
|
The latest version of jade can be download for the browser in standalone form from [here](https://github.com/jadejs/jade/raw/master/jade.js). It only supports the very latest browsers though, and is a large file. It is recommended that you pre-compile your jade templates to JavaScript and then just use the [runtime.js](https://github.com/jadejs/jade/raw/master/runtime.js) library on the client.
|
||
|
|
|
||
|
|
To compile a template for use on the client using the command line, do:
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ jade --client --no-debug filename.jade
|
||
|
|
```
|
||
|
|
|
||
|
|
which will produce `filename.js` containing the compiled template.
|
||
|
|
|
||
|
|
## Command Line
|
||
|
|
|
||
|
|
After installing the latest version of [node](http://nodejs.org/), install with:
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ npm install jade -g
|
||
|
|
```
|
||
|
|
|
||
|
|
and run with
|
||
|
|
|
||
|
|
```console
|
||
|
|
$ jade --help
|
||
|
|
```
|
||
|
|
|
||
|
