Question 1

How to use Prism to manage multiple instances of a component in React Redux?

Accepted Answer

Define your component as a view-reducer pair and use Prism's wrapping functions to namespace actions, similar to the Counters Pair example. Wrap action types hierarchically to isolate state for each instance, ensuring actions are properly scoped without manual tagging.

Question 2

Prism vs Redux Toolkit: which should I use for action handling?

Accepted Answer

Redux Toolkit provides comprehensive utilities for Redux, including action creators and reducers, while Prism focuses specifically on action composition for multi-instance components. If you need to manage multiple instances, Prism can complement Redux Toolkit by simplifying namespacing, but for general Redux needs, Redux Toolkit is more feature-rich.

Question 3

Can Prism work with Redux middleware like Saga or Thunk?

Accepted Answer

Prism wraps action types, so it should be compatible with middleware that processes actions based on type. However, you may need to ensure that wrapped actions are correctly handled, as Prism doesn't modify payloads, and middleware might require adjustments for the namespaced action types.

Question 4

How to handle side effects in a Prism-based application?

Accepted Answer

Prism itself doesn't provide side effect handling; use standard Redux middleware like Redux Thunk or Saga. Define side effects in your reducers or middleware, and Prism will handle action composition for isolated instances, keeping effects separate from the wrapping logic.

Question 5

Is Prism suitable for TypeScript projects?

Accepted Answer

Prism is a JavaScript library without built-in TypeScript definitions, so you may need to create custom types or rely on community contributions. This can add overhead for type safety, especially with action wrapping, which might require manual type annotations.

Question 6

What are the performance impacts of using Prism?

Accepted Answer

Prism adds minimal overhead by wrapping action types as strings, so performance impact is negligible in most cases. However, in applications with thousands of instances, the hierarchical namespacing could lead to longer strings, but this is unlikely to be a bottleneck compared to Redux's own operations.
