Question 1

Is Respo still maintained?

Accepted Answer

The original Respo repository is no longer actively developed, as the author has moved to Calcit-js. Maintenance has been shifted to respo.calcit, so users should rely on that fork for updates, but it may have limited community support.

Question 2

How do I create a component in Respo?

Accepted Answer

Use the defcomp macro to define functional components, as shown in the README: (defcomp comp-container [content] (div {} (<> content))). This returns virtual DOM elements and integrates with the store for reactive updates.

Question 3

Respo vs Reagent: which is better for ClojureScript?

Accepted Answer

Respo offers a more explicit virtual DOM and functional approach, while Reagent is tightly integrated with React and has a larger ecosystem. Choose Respo for a lightweight, ClojureScript-native solution, but Reagent is better supported for complex apps.

Question 4

Can Respo handle server-side rendering?

Accepted Answer

Respo is primarily designed for client-side rendering with a virtual DOM, and server-side rendering is not a built-in feature. You would need custom setup or additional libraries, which may not be well-documented in the ecosystem.

Question 5

How to manage state in Respo applications?

Accepted Answer

State is managed using ClojureScript atoms as a central store, with a dispatch function for updates. The README example shows (defonce *store (atom {})) and (dispatch! [op op-data]), enabling predictable state changes through immutable data.

Question 6

What are effects in Respo and how to use them?

Accepted Answer

Effects are side effects attached to components, defined with defeffect to handle actions like :mount or :update. For instance, (defeffect effect-a [text] [action parent-element at-place?] ...) allows running code during component lifecycle events.
