ExpressJS Extras Package
This package contains extra middleware options for ExpressJS.
Currently it only contains 2, but I will be adding to them as I need them ;)
Installation
npm install express-extras
extras.fixIP
This middleware module attempts to normalize req.socket.remoteAddress and headers['x-forwarded-for'] into req.ip
when working with a proxy (like nginx).
var extras = require('express-extras');
app.configure(function() {
app.use(extras.fixIP());
//Or
app.use(extras.fixIP([
'x-forwarded-for',
'forwarded-for',
'x-cluster-ip'
]));
});extras.throttle
Attempts to throttle requests based on the number of times a given resource is accessed.
Once the throttle is reached, a 403 is served to them for the holdTime (default 10 seconds)
127.0.0.1 is automatically whitelisted (for development, monit, nagios, etc..)
Probably should be used with/after extras.fixIP so that the users real IP is sent to the throttle.
var extras = require('express-extras');
app.configure(function() {
Use the defaults..
app.use(extras.throttle());
//Or supply a config object
//The default config shown..
app.use(extras.throttle({
urlCount: 5,
urlSec: 1,
holdTime: 10,
whitelist: {
'127.0.0.1': true
},
errorCode: 403,
errorHtml: '<html><title>403 Forbidden</title><body><h1>403 Forbidden</h1><p>Client denied by server configuration.</p></body></html>'
}));
});Build Status
