资源说明：Connect Middleware for LESS.js compiling
This middleware was created to allow processing of [Less](http://lesscss.org) files for [Connect JS](http://www.senchalabs.org/connect/) framework and by extension the [Express JS](http://expressjs.com/) framework.

[![Dependency Status](https://david-dm.org/emberfeather/less.js-middleware.svg)](https://david-dm.org/emberfeather/less.js-middleware)

## Installation

```sh
npm install less-middleware --save
```

## Usage

```js
lessMiddleware(source, [{options}])
```

### Express

```js
var lessMiddleware = require('less-middleware');

var app = express();
app.use(lessMiddleware(__dirname + '/public'));
app.use(express.static(__dirname + '/public'));
```

### `options`

The following options can be used to control the behavior of the middleware:



    
        

            Option
            Description
            Default
        

    
    
        

            debug
            Show more verbose logging?
            false
        

        

            dest
            Destination directory to output the compiled .css files.
            Same directory as less source files.
        

        

            force
            Always re-compile less files on each request.
            false
        

        

            once
            Only recompile once after each server restart. Useful for reducing disk i/o on production.
            false
        

        

            pathRoot
            Common root of the source and destination. It is prepended to both the source and destination before being used.
            null
        

        

            postprocess
            Object containing functions relevant to postprocessing data.
            
        

        

            postprocess.css
            Function that modifies the compiled css output before being stored.
            function(css, req){...}
        

        

            preprocess
            Object containing functions relevant to preprocessing data.
            
        

        

            preprocess.less
            Function that modifies the raw less output before being parsed and compiled.
            function(src, req){...}
        

        

            preprocess.path
            Function that modifies the less pathname before being loaded from the filesystem.
            function(pathname, req){...}
        

        

            preprocess.importPaths
            Function that modifies the import paths used by the less parser per request.
            function(paths, req){...}
        

        

            render
            Options for the less render. See the "render Options" section below.
            …
        

        

            storeCss
            Function that is in charge of storing the css in the filesystem.
            function(pathname, css, req, next){...}
        

        

            cacheFile
            Path to a JSON file that will be used to cache less data across server restarts. This can greatly speed up initial load time after a server restart - if the less files haven't changed and the css files still exist, specifying this option will mean that the less files don't need to be recompiled after a server restart.
            
        

    



## `render` Options

The `options.render` is passed directly into the `less.render` with minimal defaults or changes by the middleware.

The following are the defaults used by the middleware:



    
        

            Option
            Default
        

    
    
        

            compress
            auto
        

        

            yuicompress
            false
        

        

            paths
            []
        

    



## Examples

Common examples of using the Less middleware are available in the [wiki](https://github.com/emberfeather/less.js-middleware/wiki/Examples).

## Troubleshooting

### My less never recompiles, even when I use `{force: true}`!

Make sure you're declaring less-middleware before your static middleware, if you're using the same directory, e.g. (with express):


```js
var lessMiddleware = require('less-middleware');

var app = express();
app.use(lessMiddleware(__dirname + '/public'));
app.use(express.static(__dirname + '/public'));
```

not

```js
var lessMiddleware = require('less-middleware');

var app = express();
app.use(express.static(__dirname + '/public'));
app.use(lessMiddleware(__dirname + '/public'));
```

### IIS

If you are hosting your app on IIS you will have to modify your `web.config` file in order to allow NodeJS to serve your CSS static files.  IIS will cache your CSS files, bypassing NodeJS static file serving, which in turn does not allow the middleware to recompile your LESS files.
