Restores request origin ip to `req.origin_ip`. Denies other requests.
npm install cloudflare-middlewareRestores request origin ip to req.origin_ip. Denies other requests.
``nodejs`
let app = express();
app.use(require("cloudflare-middleware")());
This is a safer alternative to naively using app.set("trust proxy");, as this checks CloudFlare IP address ranges.
This, however, has been deprecated in favor of the following:
``nodejs
const cloudflareIp = require('cloudflare-ip');
app.set('trust proxy', ip => {
if(ip.startsWith('::ffff:'))
ip = ip.substr(7);
return ip == '127.0.0.1' || cloudflareIp(ip);
});
