Arcjet Remix example app

Arcjet helps developers protect their apps in just a few lines of code. Bot detection. Rate limiting. Email validation. Attack protection. Data redaction. A developer-first approach to security.

This is an example Remix application demonstrating the use of multiple features. There is a version deployed at https://example.arcjet.com.

Features

  • Signup form protection uses Arcjet's server-side email verification configured to block disposable providers and ensure that the domain has a valid MX record. It also includes rate limiting and bot protection to prevent automated abuse.
  • Bot protection shows how a page can be protected from automated clients.
  • Rate limiting shows the use of different rate limit configurations depending on the authenticated user. A logged-in user can make more requests than an anonymous user.
  • Attack protection demonstrates Arcjet Shield, which detects suspicious behavior, such as SQL injection and cross-site scripting attacks.
  • Sensitive info protects against clients sending you sensitive information such as PII that you do not wish to handle.

Run locally

  1. Register for a free Arcjet account.

  2. Install dependencies:

npm ci

  1. Rename .env.example to .env and add your Arcjet key. If you want to test the rate limiting authentication, you will also need to add a GitHub app key and secret after creating a GitHub OAuth app.

  2. Start the dev server

npm run dev
  1. Open http://localhost:3000 in your browser.

Deploy

If you use this for production, edit the app/sessions.server.ts file to include your domain.
