dish

miniature in-memory http static middleware optimized for serving buffers or strings

Given a file path, string or buffer, dish will create you an HTTP server request listener, with added benefits:

• gzip/deflate support
• ETag / Conditional GET support
• In-memory LRU cache (faster than accessing the disk for every request)

Install

$ npm install --save dish

Basic usage

To serve a raw string or buffer:

var dish = require('dish')
  , server = require('http').createServer()

server.on('request', dish('hello world!')); // can also accept a Buffer instance
server.listen(3000);

To serve a file (mime-type autodetected from file name)

server.on('request', dish.file('./facepalm.jpg'));

Options

You can pass options as the second parameter to dish().

• headers (Object) - override / specify headers to send. Be sure to set a Content-Type header if you are serving a string or buffer.
• status (Number) - status code for the response, defaults to res.statusCode or 200.

Middleware example

var dish = require('dish')
  , middler = require('middler')
  , server = require('http').createServer()

middler(server)
  // a simple "about us" page
  .get('/about', dish.file('./about.html'))
  // Serve a dynamic javascript file with gzip support:
  .get('/my-code.js', function (req, res, next) {
    // create some dynamic javascript...
    var myCode = 'var myNumber = ' + Math.random();
    // serve it
    dish(myCode, {headers: {'Content-Type': 'text/javascript'}})(req, res);
  });

server.listen(3000);

Tweaking the LRU cache

By default, dish uses a 256 MB LRU cache to transparently cache files.

• To clear a single cache entry, use dish.clearCache(filepath).
• To clear all cache entries, use dish.clearCache().
• To set cache options, such as max bytes, use dish.cache.setOptions(options). Supports options that lru-cache supports.
• To access the cache directly (an lru-cache instance), use dish.cache.backend.
• To disable the cache, use dish.cache.setOptions({max: 0})
