KoaJS middleware for combining static files at serverside to reduce the number of http requests.

$ npm install koa-combo

Enabling combo is as simple as following

var koa = require('koa'),
  app = koa(),
  combo = require('koa-combo');

app.use(combo(['example-parts/']));

To access your combined static files, use the query string pattern combo=path-of-file-1,path-of-file-2,path-of-file-3,....

Enable combo.

Parameters:

• allowedPrefix (string|array[string])

You should always specify array allowedPrefix. All files do not begin with any string in allowedPrefix will not be served.

For security concern, you cannot use .. in the file path. For example, http://assets.domain.com/?combo=myasset/../images is not allowed.

Run example.js in harmony mode. Ensure your node supports ES6 harmony mode.

$ node --harmony example.js

Then visit http://localhost:3000/?combo=example-parts/part1.js,example-parts/part2.js, you will get the combined version of example-parts/part1.js and example-parts/part2.js. Files are concatenated by the given order in query string.
