serve-index

Serves pages that contain directory listings for a given path.

Install

$ npm install serve-index

API

var serveIndex = require('serve-index')

serveIndex(path, options)

Returns middlware that serves an index of the directory in the given path.

The path is based off the req.url value, so a req.url of '/some/dir with a path of 'public' will look at 'public/some/dir'. If you are using something like express, you can change the URL "base" with app.use (see the express example).

Options

Serve index accepts these properties in the options object.

filter

Apply this filter function to files. Defaults to false. The filter function is called for each file, with the signature filter(filename, index, files, dir) where filename is the name of the file, index is the array index, files is the array of files and dir is the absolute path the file is located (and thus, the directory the listing is for).

hidden

Display hidden (dot) files. Defaults to false.

icons

Display icons. Defaults to false.

stylesheet

Optional path to a CSS stylesheet. Defaults to a built-in stylesheet.

sort

Apply this sort function to files. Optional. The sort function is called for each file tuple with the signature sort(file1, file2). An example for sorting files by date of modification (descending) is:

function(file1, file2) {
  // sort ".." to the top
  if (file1.name === '..' || file2.name === '..') {
    return file1.name === file2.name ? 0
      : file1.name === '..' ? -1 : 1;
  }
  // sort directories first then files by date of modification
  return Number(file2.stat && file2.stat.isDirectory()) - Number(file1.stat && file1.stat.isDirectory()) ||
    new Date(file2.stat.mtime) - new Date(file1.stat.mtime);
}

template

Optional path to an HTML template or a function that will render a HTML string. Defaults to a built-in template.

When given a string, the string is used as a file path to load and then the following tokens are replaced in templates:

• {directory} with the name of the directory.
• {files} with the HTML of an unordered list of file links.
• {linked-path} with the HTML of a link to the directory.
• {style} with the specified stylesheet and embedded images.

When given as a function, the function is called as template(locals, callback) and it needs to invoke callback(error, htmlString). The following are the provided locals:

• directory is the directory being displayed (where / is the root).
• displayIcons is a Boolean for if icons should be rendered or not.
• fileList is a sorted array of files in the directory. The array contains objects with the following properties:
  • name is the relative name for the file.
  • stat is a fs.Stats object for the file.
• path is the full filesystem path to directory.
• style is the default stylesheet or the contents of the stylesheet option.
• viewName is the view name provided by the view option.

view

Display mode. tiles and details are available. Defaults to tiles.

Examples

Serve directory indexes with vanilla node.js http server

var finalhandler = require('finalhandler')
var http = require('http')
var serveIndex = require('serve-index')
var serveStatic = require('serve-static')

// Serve directory indexes for public/ftp folder (with icons)
var index = serveIndex('public/ftp', {'icons': true})

// Serve up public/ftp folder files
var serve = serveStatic('public/ftp')

// Create server
var server = http.createServer(function onRequest(req, res){
  var done = finalhandler(req, res)
  serve(req, res, function onNext(err) {
    if (err) return done(err)
    index(req, res, done)
  })
})

// Listen
server.listen(3000)

Serve directory indexes with express

var express    = require('express')
var serveIndex = require('serve-index')

var app = express()

// Serve URLs like /ftp/thing as public/ftp/thing
app.use('/ftp', serveIndex('public/ftp', {'icons': true}))
app.listen()
