koa-send Build Status

Static file serving middleware.

Installation

$ npm install koa-send

Options

  • maxage Browser cache max-age in milliseconds. defaults to 0
  • hidden Allow transfer of hidden files. defaults to false
  • root Root directory to restrict file access

Root path

Note that when root is not used you MUST provide an absolute path, and this path must not contain "..", protecting developers from concatenating user input. If you plan on serving files based on user input supply a root directory from which to serve from.

For example to serve files from ./public:

app.use(function *(){
  yield send(this, this.path, { root: __dirname + '/public' });
})

To serve developer specified files:

app.use(function *(){
  yield send(this, 'path/to/my.js');
})

Example

var send = require('koa-send');
var koa = require('koa');
var app = koa();

// $ GET /package.json
// $ GET /

app.use(function *(){
  if ('/' == this.path) return this.body = 'Try GET /package.json';
  yield send(this, __dirname + '/package.json');
})

app.listen(3000);
console.log('listening on port 3000');
