serve-favicon

Node.js middleware for serving a favicon.

Why use this module?

• User agents request favicon.ico frequently and indiscriminately, so you may wish to exclude these requests from your logs by using this middleware before your logger middleware.
• This module caches the icon in memory to improve performance by skipping disk access.
• This module provides an ETag based on the contents of the icon, rather than file system properties.
• This module will serve with the most compatible Content-Type.

Install

npm install serve-favicon

API

favicon(path, options)

Create new middleware to serve a favicon from the given path to a favicon file. path may also be a Buffer of the icon to serve.

Options

Serve favicon accepts these properties in the options object.

maxAge

The cache-control max-age directive in ms, defaulting to 1 day. This can also be a string accepted by the ms module.

Examples

Typically this middleware will come very early in your stack (maybe even first) to avoid processing any other middleware if we already know the request is for /favicon.ico.

express

var express = require('express');
var favicon = require('serve-favicon');

var app = express();
app.use(favicon(__dirname + '/public/favicon.ico'));

// Add your routes here, etc.

app.listen(3000);

connect

var connect = require('connect');
var favicon = require('serve-favicon');

var app = connect();
app.use(favicon(__dirname + '/public/favicon.ico'));

// Add your middleware here, etc.

app.listen(3000);

vanilla http server

This middleware can be used anywhere, even outside express/connect. It takes req, res, and callback.

var http = require('http');
var favicon = require('serve-favicon');
var finalhandler = require('finalhandler');

var _favicon = favicon(__dirname + '/public/favicon.ico');

var server = http.createServer(function onRequest(req, res) {
  var done = finalhandler(req, res);

  _favicon(req, res, function onNext(err) {
    if (err) return done(err);

    // continue to process the request here, etc.

    res.statusCode = 404;
    res.end('oops');
  });
});

server.listen(3000);
