NoMoreJunk Email Validator

Hey there! 👋 This is a super handy API service that helps you check if an email address is using a disposable/temporary domain. You know those pesky throwaway email addresses that people use to bypass verification? Yeah, we catch those!

What's Cool About This?

• Super Fast Checks: We use Redis caching to make checks lightning fast
• Smart Domain Detection: Can catch similar-looking domains (like gmaill.com trying to pose as gmail.com)
• Maintainable Lists: Automatically syncs allowlist and blocklist from GitHub repositories
• Audit Trail: Keeps track of all email checks with IP addresses for security
• API-First: Built with Hono.js for a lightweight but powerful API

Getting Started

First, make sure you have Bun installed (we're using it for that sweet performance). Then:

# Install all the goodies
bun install

# Fire up the development server
bun run dev

The server will start at http://localhost:3000

Environment Variables You'll Need

Create a .env file with these:

DATABASE_URL=your_postgres_connection_string
REDIS_URL=your_redis_url
BLOCKLIST_URL=github_raw_url_to_blocklist
ALLOWLIST_URL=github_raw_url_to_allowlist
