Question 1

How to get started with re-frame and ClojureScript?

Accepted Answer

Start by setting up a ClojureScript project with a build tool like Shadow CLJS or Leiningen, then add re-frame and Reagent dependencies. The documentation provides templates and guides, but expect a steeper initial setup compared to JavaScript frameworks.

Question 2

re-frame vs Redux: which is better for state management?

Accepted Answer

Both manage state functionally, but re-frame is built on ClojureScript with immutable data and an event-driven model, offering built-in patterns for effects. Redux is JavaScript-based and more flexible but requires more boilerplate; re-frame excels in ClojureScript ecosystems with less churn.

Question 3

Can I use React hooks with re-frame?

Accepted Answer

re-frame's architecture treats views as purely reactive, so it doesn't integrate directly with React hooks. Instead, it uses its own event and subscription system, which may require a mindset shift from hook-based development.

Question 4

How does re-frame handle API calls and side effects?

Accepted Answer

re-frame uses effects and co-effects to manage side effects like API calls. Events dispatch effects that perform asynchronous tasks, with state updates handled through pure functions, ensuring a predictable and testable flow.

Question 5

What are the debugging tools for re-frame?

Accepted Answer

re-frame provides devtools for time-travel debugging, allowing you to inspect the event log and state changes. This is facilitated by its immutable data and pure function design, making it easier to trace issues in large applications.

Question 6

Is re-frame suitable for mobile app development?

Accepted Answer

re-frame can be used with React Native via ClojureScript bindings, but it's primarily optimized for web SPAs. The mobile ecosystem has fewer resources and community support, so it might require more custom integration work.
