Tor detect middleware for Express
# About
Tor detect middleware for Express.
❤️ Awesome Features:
- Easy to redirect Tor or Surface users. 🔥
- Easy to recognize TorUsers at inside the `req` object, `req.isTorUser` 🍺
- No infra required, the database is json based using `lowdb` 🎉
- The `strictMode` won't allow any request to access until the relays IPs are collected 📦
- The `purge` allow you to dump the database at startup ☣️
- `debug` is supported 💪
- Refresh time is customizable 🧐
- Easy to use and great test coverage ✅
```js
const express = require('express');
const torUserHandler = require('tor-detect-middleware')
const app = express();
app.use(torUserHandler())
app.get('/', (req, res) => {
const ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;
res.send(`Are you (${ip}) a TOR user? ${req.isTorUser}`);
});
app.listen(3000, () => {
console.log('We are in port 3000!');
});
```
## Usage
### Install
```bash
npm install tor-detect-middleware
```
### simple example
```js
const express = require('express');
const torUserHandler = require('tor-detect-middleware')
const app = express();
app.use(torUserHandler())
app.get('/', (req, res) => {
const ip = req.headers['x-forwarded-for'] || req.connection.remoteAddress;
res.send(`Are you (${ip}) a TOR user? ${req.isTorUser}`);
});
app.listen(3000, () => {
console.log('We are in port 3000!');
});
```
### Redirect Users
In this example we redirect the surface users to `https://www.nytimes.com` and Tor users to `https://www.nytimes3xbfgragh.onion/`. You can use both ways to redirect.
```js
const express = require('express');
const torUserHandler = require('tor-detect-middleware')
const app = express();
app.use(torUserHandler({
surface: "https://www.nytimes.com",
tor: "https://www.nytimes3xbfgragh.onion/"
}))
app.listen(3000, () => {
console.log('We are in port 3000!');
});
```
### Ban users from surface or TOR
```js
const express = require('express');
const torUserHandler = require('tor-detect-middleware')
const app = express();
app.use(torUserHandler())
app.get('/surface-only', (req, res) => {
if(req.isTorUser) return res.status(401).send("You can't access from TOR here")
res.send('Welcome surface user!');
});
app.get('/tor-only', (req, res) => {
if(!req.isTorUser) return res.status(401).send("You can't access from the surface here")
res.send('Welcome to the dark side. We have cookies!');
});
app.listen(3000, () => {
console.log('We are in port 3000!');
});
```
### Custom Cron Jobs
By default we refresh the IP list every hour, but you can modify the ms as you wish.
```js
const express = require('express');
const torUserHandler = require('tor-detect-middleware')
const app = express();
app.use(torUserHandler({refreshMs: 600000}))
//...
```
### Strict Mode
Special behaviour in Strict mode:
- The server will stop at startup if `https://onionoo.torproject.org/details` url is down
- The server will wait until there is a list ready to dispatch requests. (Few seconds)
_Note: if there is a list stored you wont surfer any problem, as we start the service from the previous list._
```js
const express = require('express');
const torUserHandler = require('tor-detect-middleware')
const app = express();
app.use(torUserHandler({
strictMode: true
}))
//...
```
### Purge list at start
You can purge the list by default at the startup of the service.
```js
const express = require('express');
const torUserHandler = require('tor-detect-middleware')
const app = express();
app.use(torUserHandler({
purge: true
}))
//...
```
