Inline Static Files for your template

Why this?

  1. Add compressed inline css and scripts to your html, but write them as seperated files.
  2. Access template’s variables from a JS file.

For concat and serve external css/jss, go have a look at autostatic.

Usage:

var istatic = require('istatic')
va app = express.createServer()

app.locals({
  istatic: istatic.serve({ compress: false })
})

Available options for istatic.server([options]) are:

| name | description | default | | root | The root of your inline static files. | process.cwd() + ‘/public/’ | | ttl | By default, the contents of your static files are cached in memory forever, until the process dies. You can set the ttl to a number of seconds, then the cache will be cleared every that much of time. | undefined | | charset | The charset of your static files. | utf-8 | | compress | Whether to compress the included contents. | false | | cache | Whether to cache file contents. | true | | debug | When set to true, will output the absolute path of included file. And compress & cache will all be set to false. | process.env.DEBUG | | js | Options passed to UglifyJS, for compressing JS files. | undefined | | css | Options passed to clean-css | undefined |

For css and js options, you can also define a js.filter or css.filter, to do some extra filtering (like remove console.log()) before compressing.

eg.

{
  js: {
    filter: function(str) {
      return str.replace(/console.log(.+?)/, '')
    }
  }
}

In template:

Now you can include static files in your template like this:

   html
    title Sweet Page.
    head
     style.
       #{istatic(filename)}

filename is the path of your static file.

Templates’ Local Variables:

Access template’s render context (locals) inside your JS file, in the form you already very familiar with:

#{data.title}

You can even excecute a local funtion just like what you will do in html templates:

#{usr.getId('haha...')}

Attention: no matter what templating language you are using, you must always use this syntax in your static files. And don’t put {} inside the curly braces. This is for performance consideration.


API

These APIs are not for templates.

istatic.serve([options])

Return a function of istatic(filename, [options]), for reading files.

The function is typically used as a template helper, the signature is:

istatic(filename)

Return the string content of given file. If filename begins with a '/', the real path will be process.cwd() + filename. Otherwise, the file will be looked up from the options.root, as you configured in istatic.serve(options).

istatic.default(options)

Explicitly set default options for any other istatic.serve() calls. The default options may have been set implicitly during the first call of istatic.serve(options).

Example

In /app.js:

var express = require('express')
var istatic = require('istatic')

var app1 = express.createServer()
var app2 = express.createServer()

app1.locals({
  istatic: istatic.serve()
})
app2.locals({
  istatic: istatic.serve({ compress: false })
})

var compressed_css = istatic.uglify.css('.class1 { font: Arial }');
var compressed_js = istatic.uglify.js('// some javascript codes..')

// will be compressed
var str_pinyin_js = istatic('/utils/pinyin.js')

app1.get('/example', function(req, res, next) {
  res.render('example.jade', {
    user: req.user
  })
})

In /view/example.jade:

script
  !{istatic('js/log_user.js')}

In /public/js/log_user.js:

var user = "#{user}"
user && $.post('/log', { user: user })
