Question 1

How to handle POST requests with JSON data in Compojure?

Accepted Answer

Use the POST macro with a handler that parses the request body. Integrate Ring middleware like ring-json to automatically parse JSON, then access the data in your handler function for processing.

Question 2

Compojure vs Reitit: which is better for Clojure web apps?

Accepted Answer

Compojure is simpler and more established, ideal for basic routing with Ring. Reitit offers more features like data-driven routes and better performance, but has a steeper learning curve. Choose based on your need for simplicity versus advanced capabilities.

Question 3

How to add authentication to a Compojure app?

Accepted Answer

Compojure doesn't provide authentication out of the box. Use Ring middleware, such as friend or buddy, to handle authentication and integrate it with your Compojure routes by wrapping handlers or using middleware stacks.

Question 4

What's the best way to organize large Compojure applications?

Accepted Answer

Break routes into separate namespaces and use defroutes to combine them. This modular approach keeps code clean and allows for reuse, following functional composition patterns highlighted in the philosophy.

Question 5

How does Compojure handle async requests?

Accepted Answer

Compojure supports asynchronous handlers by returning a promise or future from route handlers. This integrates with Ring's async capabilities, enabling non-blocking operations for improved performance.

Question 6

Can I use Compojure with ClojureScript for frontend routing?

Accepted Answer

No, Compojure is designed for server-side Clojure with Ring. For client-side routing in ClojureScript, consider libraries like re-frame or secretary, as Compojure won't work in that context.
