# **ReqWeb - Web Application Firewall (WAF)**
**ReqWeb** is a lightweight and customizable **Web Application Firewall (WAF)** for Node.js. It provides IP-based filtering, request rate limiting, and logging, helping to protect your web applications from malicious traffic and unauthorized access.
## **Features**
- **IP Filtering**: Block or allow specific IPs or CIDR ranges.
- **Rate Limiting**: Control the frequency of requests to prevent abuse.
- **Request Blocking**: Define custom rules to block unwanted requests.
- **Logging**: Detailed request logging to monitor security events.
- **Easy Integration**: Drop-in middleware for Express.js or any Node.js application.
## **Installation**
To install **ReqWeb**, simply run the following command:
```bash
npm install reqweb
```
## **Usage**
### Basic Setup with Express.js
1. **Import the package**:
First, require **ReqWeb** in your application:
```javascript
const express = require('express');
const reqweb = require('reqweb');
const apiRoutes = require('./web/public/routes/api');
const ipFilter = require('reqweb/src/middlewares/ipFilter');
const ruleEngine = require('reqweb/src/middlewares/ruleEngine');
const logger = require('reqweb/src/middlewares/logger');
```
2. **Load Configuration**:
**ReqWeb** allows you to customize your configuration by loading a `userConfig.json` file. Here’s an example of how to load it:
```javascript
/*user defined rules and configs currently not implementet and
working on an interface for easy config*/
const config = configLoader('reqweb/src/config/usertConfig.json');
```
**Using default config**
```javascript
const config = configLoader('reqweb/src/config/defaultConfig.json');
```
3. **Apply the Middlewares**:
Add the IP filtering middleware to your Express app:
```javascript
const app = express();
// Apply WAF middlewares
app.use(logger(config)); // Logging middleware
app.use(ipFilter(config)); // IP filtering middleware
app.use(rateLimiter(config)); // Rate limiting middleware
app.use(ruleEngine(config)); // Rule-based request blocking
//adding WAF web interface
app.use('/reqweb/api', apiRoutes);
app.get('/', (req, res) => {
res.send('Welcome to Homelab!');
});
//running your app with WAF web interface enabled
reqweb.startInterface(app, 3000);
```
## Accessing ReqWeb web interface
with the above setup you will have access to your waf web configuration interface at the following address:
`http://localhost:3000/reqweb/api/web`
### Configuration Example
In the `userConfig.json` file, you can define the list of blocked and allowed IPs:
```json
{
"blockedIPs": ["192.168.1.100", "203.0.113.0/24"],
"allowedIPs": ["127.0.0.1", "::1"]
}
```
### Customizing the Middleware
You can modify or extend the behavior of **ReqWeb** by tweaking the `ipFilter.js` middleware or adding your own custom rules.
---
## **Configuration Options**
- **blockedIPs**: Array of IP addresses or CIDR ranges to block (e.g., `["192.168.1.100", "203.0.113.0/24"]`).
- **allowedIPs**: (Optional) Array of IP addresses or CIDR ranges that are allowed even if the `blockedIPs` list would block them (e.g., `["127.0.0.1", "::1"]`).
## **Advanced Features**
- **Rate Limiting**: Set up rate limiting to avoid abusive requests.
- **Logging**: Enable logging using **winston** for better monitoring of requests and events.
### Example of rate-limiting setup:
You can extend **ReqWeb** to add rate-limiting by combining it with other libraries like **express-rate-limit**.
---
## **Development & Testing**
### Run Tests
To run tests, use **Mocha** and **Chai** for testing:
```bash
npm test
```
### Build the Package
If you're using TypeScript or want to transpile code, you can build the project like this:
```bash
npm run build
```
