Question 1

How do I use React hooks with Helix in ClojureScript?

Accepted Answer

Helix provides a helix.hooks namespace with functions like use-state and useEffect that mirror React's hooks but use ClojureScript syntax. For example, use-state returns a vector of state and setter, integrating seamlessly with immutable data structures.

Question 2

Helix vs Reagent for ClojureScript React development?

Accepted Answer

Helix is optimized for modern React with hooks and functional components, offering a direct React API layer. Reagent uses a hiccup-based approach and has a larger historical community. Choose Helix for new projects embracing React's latest features, while Reagent might suit those preferring a more Clojure-centric abstraction.

Question 3

How to set up Helix with shadow-cljs for a new project?

Accepted Answer

Install helix from Clojars, then add react and react-dom via npm. Configure shadow-cljs.edn to include dependencies and set up a build target, referring to the React Native documentation for specific instructions, as it requires additional steps for tool integration.

Question 4

Does Helix support server-side rendering?

Accepted Answer

The README doesn't explicitly cover SSR, but since Helix works with React DOM, it should be possible by leveraging React's SSR capabilities. However, you'll need to handle configuration manually, as Helix provides no built-in SSR utilities.

Question 5

How to optimize component performance in Helix?

Accepted Answer

Use memoization via React.memo with Helix's utilities, and apply hooks like use-memo and use-callback. The pro-tips section advises against deep equals and suggests creating custom macros for better control over re-renders.

Question 6

Can I use Helix with React Native?

Accepted Answer

Yes, Helix is compatible with React Native. The documentation includes a dedicated section for setup, requiring additional npm dependencies and configuration with build tools like shadow-cljs to bridge ClojureScript and React Native environments.
