Question 1

How to use p-tap with async/await?

Accepted Answer

p-tap is designed for promise chains, so you need to wrap async functions in promises. For example, use `Promise.resolve(asyncFunction()).then(pTap(...))`, but it's more natural with .then() chains than direct async/await integration.

Question 2

p-tap vs manual .then() for logging?

Accepted Answer

p-tap provides a cleaner, declarative way to inject side effects without risking value changes, whereas manual .then() requires careful coding to avoid altering the promise. p-tap reduces boilerplate and potential errors in complex chains.

Question 3

Does p-tap work with fetch API?

Accepted Answer

Yes, p-tap works with any promise, including those from fetch. You can chain it after fetch calls to log responses or perform side effects, as shown in the usage examples with Promise.resolve.

Question 4

How to handle errors with p-tap?

Accepted Answer

Use pTap.catch() in .catch() methods to tap into errors without affecting error propagation. For instance, `.catch(pTap.catch(console.error))` logs errors while still allowing subsequent error handling.

Question 5

What are alternatives to p-tap?

Accepted Answer

Alternatives include native promise methods, libraries like Bluebird with tap, or other utilities from the promise-fun collection. p-tap is minimal, while others might offer more features but with added complexity.

Question 6

p-tap performance overhead?

Accepted Answer

p-tap is lightweight, but it adds an extra function call in the promise chain. In performance-critical applications, this overhead might be noticeable, though for most use cases, it's negligible.
