Cro vs Relay

Raku's answer to async chaos meets graphql's overbearing but brilliant bodyguard. Here's our take.

Cro

Nice Pick

Raku's answer to async chaos. Build reactive APIs without the callback hell.

Pros

• Leverages Raku's built-in concurrency for high-performance I/O
• Strong type safety and composability for scalable network services
• Excellent support for real-time features like WebSocket servers

Cons

• Limited ecosystem compared to mainstream frameworks like Node.js or Go
• Requires familiarity with Raku, which has a niche adoption

Relay

GraphQL's overbearing but brilliant bodyguard. It'll fetch your data perfectly, but good luck arguing with it.

Pros

• Automatic caching and pagination out of the box
• Declarative data fetching reduces boilerplate code
• Optimized network requests for better performance

Cons

• Steep learning curve with complex setup and conventions
• Tight coupling to GraphQL can limit flexibility

The Verdict

Use Relay if: You prioritize automatic caching and pagination out of the box over what Cro offers.

The Bottom Line
