Question 1

How to handle HTTP requests in Cycle.js?

Accepted Answer

Use the @cycle/http package, which provides drivers to make HTTP calls and manage responses as observable streams, integrating seamlessly with the functional core.

Question 2

Cycle.js vs React: which is better for state management?

Accepted Answer

Cycle.js uses streams for predictable, declarative data flow, while React relies on hooks or context; Cycle.js offers more explicit control but requires familiarity with reactive programming.

Question 3

What are drivers in Cycle.js and how do they work?

Accepted Answer

Drivers are functions that handle side effects like DOM updates or HTTP requests, isolating them from pure application logic to maintain testability and separation of concerns.

Question 4

Is Cycle.js good for building large-scale applications?

Accepted Answer

Yes, its modular architecture and explicit side effects aid maintainability for complex apps, but the smaller ecosystem might require more custom development and internal expertise.

Question 5

How to test Cycle.js applications effectively?

Accepted Answer

Leverage the pure functional core by mocking streams and drivers, making unit testing straightforward since business logic is isolated from side effects.

Question 6

Cycle.js performance compared to Vue or Angular?

Accepted Answer

Cycle.js's stream-based approach can optimize complex data flows, but may introduce overhead for simple UIs compared to frameworks with virtual DOM or change detection.
