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.

0.0.24

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

npm install express-ipfilter

Blacklisting certain IP addresses, while allowing all other IPs:

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

// Whitelist 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:

var ips = ['127.0.0.1/24'];

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

Using IP ranges:

var ips = [['127.0.0.1','127.0.0.10']];

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

You can run grunt to build the source. This will run eslint and babel against src/ipfilter.js.

There is an included example project that will load the package from the local build for testing.

Run tests by using

grunt test

This will run eslint,babel, and mocha and output coverage data into coverage. Any pull request you submit needs to be accompanied by a test.
