Question 1

How does Tansu compare to Svelte stores?

Accepted Answer

Tansu extends Svelte stores with features like computed stores and batch updates, fixing glitches such as the asymmetric diamond problem while remaining fully compatible. It offers more flexibility and performance optimizations for derived state.

Question 2

Can I use Tansu with React?

Accepted Answer

Yes, Tansu is framework-agnostic and can be used with React, but it requires manual integration since it doesn't provide built-in hooks. You can subscribe to stores in useEffect or create custom hooks for reactivity.

Question 3

What's the difference between derived and computed in Tansu?

Accepted Answer

Derived stores require explicit dependencies and can handle asynchronous state with set methods, while computed stores have implicit dependencies and better performance by re-running only when used dependencies change, but cannot manage async operations.

Question 4

How to handle async operations in Tansu?

Accepted Answer

Use derived stores with the set method for async logic, as shown in the README example with setTimeout. Computed stores don't support async, so derived is necessary for such scenarios.

Question 5

Is Tansu good for large applications?

Accepted Answer

Tansu's minimal design is flexible, but for large-scale apps, you may need to implement additional patterns for state organization, debugging, and persistence, as it lacks built-in solutions for these.

Question 6

Does Tansu work with Angular's change detection?

Accepted Answer

Yes, Tansu stores work well with Angular and can be used with the async pipe, as demonstrated in the README. Stores implement InteropObservable, making them compatible with Angular's reactive patterns.
