Question 1

How to create a readable stream from an array using from2?

Accepted Answer

You can implement a custom read function to emit array elements, or use community extensions like 'from2-array' referenced in the SEE ALSO section for a simpler, drop-in solution.

Question 2

What's the difference between from2 and through2?

Accepted Answer

from2 is designed specifically for creating readable streams with backpressure handling, while through2 is geared towards transform streams for data manipulation; from2 simplifies readable stream creation, whereas through2 focuses on processing data in transit.

Question 3

Is from2 suitable for streaming large files?

Accepted Answer

Yes, due to its proper backpressure management, it can handle large data streams efficiently, but you need to ensure your read function is optimized to chunk data appropriately to avoid performance bottlenecks.

Question 4

How to handle errors in from2 streams?

Accepted Answer

Pass errors as the first argument in the `next` callback within the read function, and listen to standard Node.js stream error events; the README shows error handling in the read implementation example.

Question 5

Can I use from2 with async/await?

Accepted Answer

Yes, you can adapt the read function to use async operations by calling `next` after async tasks complete, but be cautious to maintain backpressure by not overwhelming the stream with unchecked data emissions.

Question 6

from2 or native Node.js streams for new projects?

Accepted Answer

Choose from2 if you want a simplified API with automatic backpressure handling and are okay with the abstraction; opt for native streams if you need full control, minimal overhead, and are comfortable managing backpressure manually.
