Package Exports

express-ipfilter

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (express-ipfilter) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

IP Filter: A light-weight IP address based filtering system

This package provides easy IP based access control. This can be achieved either by blacklisting certain IPs and whitelisting all others, or whitelisting certain IPs and blacklisting all others.

Version

0.0.5

Requirements

Node

Installation

Recommended installation is with npm. To add node-ipfilter to your project, do:

npm install ipfilter

Usage with Express

Blacklisting certain IP addresses, while allowing all other IPs:

// Init dependencies
var express = require('express')
    , ipfilter = require('ipfilter')
    , app = express.createServer()
    ;

// Blacklist the following IPs
var ips = ['127.0.0.1'];

// Create the server
app.use(ipfilter(ips));
app.listen(3000);

Whitelisting certain IP addresses, while denying all other IPs:

// Init dependencies
var express = require('express')
    , ipfilter = require('ipfilter')
    , app = express.createServer()
    ;

// Blacklist the following IPs
var ips = ['127.0.0.1'];

// Create the server
app.use(ipfilter(ips, {mode: 'allow'}));
app.listen(3000);

Using CIDR subnet masks for ranges:

// Init dependencies
var express = require('express')
    , ipfilter = require('ipfilter')
    , app = express.createServer()
    ;

// Blacklist the following IPs
var ips = ['127.0.0.1/24'];

// Create the server
app.use(ipfilter(ips, {mode: 'allow'}));
app.listen(3000);
