Questions asking us to recommend or find a book, tool, software library, tutorial or other off-site resource are off-topic for Stack Overflow as they tend to attract opinionated answers and spam. Instead, describe the problem and what has been done so far to solve it.

要求我们推荐或找到书籍,工具,软件库,教程或其他场外资源的问题都是Stack Overflow的主题,因为它们往往会吸引固执己见的答案和垃圾邮件。相反,描述问题以及到目前为止已经做了什么来解决它。

I found https://github.com/toogle/express-less/blob/master/lib/express-less.js according their package.json file, Express LESS middleware uses the latest version of Node Less.

我根据他们的package.json文件找到了https://github.com/toogle/express-less/blob/master/lib/express-less.js,Express LESS中间件使用最新版本的Node Less。

In their code the call less.render() here: https://github.com/toogle/express-less/blob/master/lib/express-less.js#L68 and more information can be found here: http://lesscss.org/usage/#programmatic-usage

在他们的代码中调用less.render()在这里:https://github.com/toogle/express-less/blob/master/lib/express-less.js#L68和更多信息可以在这里找到:http:/ /lesscss.org/usage/#programmatic-usage

Since version 2 of Less you can use plugins. An autoprefix plugin is available at: https://github.com/less/less-plugin-autoprefix

从Less版本2开始,您可以使用插件。 autoprefix插件可从以下网址获得:https://github.com/less/less-plugin-autoprefix

So you should be able to use the follow code:

所以你应该能够使用以下代码:

var express = require('express'),
    expressLess = require('express-less'),
    autoprefixer = require('less-plugin-autoprefix');

var app = express();
app.use('/less-css', expressLess(__dirname + '/less',  { plugins: [autoprefixer] }));

Notice i did not test the above code. I wondered how to set the autoprefixer option. According to https://github.com/plus3network/gulp-less#using-plugins you should use:

注意我没有测试上面的代码。我想知道如何设置autoprefixer选项。根据https://github.com/plus3network/gulp-less#using-plugins你应该使用:

var autoprefixerPlugin = require('less-plugin-autoprefix'),
autoprefixer = new autoprefixerPlugin({options});
var app = express();
    app.use('/less-css', expressLess(__dirname + '/less',  { plugins: [autoprefixer] }));

According to the documentation of Less Engine, the way to use a plugin is the following:

根据Less Engine的文档,使用插件的方法如下:

less.render(myCSS, { plugins: [myPlugin] })

less.render(myCSS,{plugins:[myPlugin]})

Source: http://lesscss.org/usage/#plugins-using-a-plugin-in-code

Then according to the documentation of Less Middleware, the way to add options into second parameter of render() function is the following:

然后根据Less Middleware的文档,将选项添加到render()函数的第二个参数中的方法如下:

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

options.render直接传递给less.render,具有最小的默认值或中间件的更改。

Source: https://github.com/emberfeather/less.js-middleware#render-options

So according to the documentation of Less Autoprefixer ande the documentation of Express Engine, the definitive and true way to use it is using this code:

因此,根据Less Autoprefixer的文档和Express Engine的文档,使用它的确切和真实的方法是使用以下代码:

var express = require('express'),
    lessMiddleware = require('less-middleware'),
    lessPluginAutoprefix = require('less-plugin-autoprefix'),
    app = express(),
    autoprefixPlugin = new lessPluginAutoprefix({ 
        browsers: ["last 2 versions"] 
    });

app.use(lessMiddleware(path.join(__dirname, 'public'), {
    render: {
        plugins: [
            autoprefixPlugin
        ]
    }
}));

This was implemented and tested in the NodeAtlas NPM module.

这是在NodeAtlas NPM模块中实现和测试的。
