Question 1

How to use merge-stream with gulp for parallel tasks?

Accepted Answer

Follow the Gulp example in the README: create separate streams for different file types, pipe them through validators, and use merge-stream to combine the outputs into a single stream for the task. This is ideal for linting or processing multiple assets simultaneously.

Question 2

merge-stream vs stream-combiner: which should I use?

Accepted Answer

merge-stream is better for interleaving multiple streams in parallel, like in gulp tasks, while stream-combiner or other libraries might offer more control for sequential merging or complex transformations. Choose based on whether you need interleaved or ordered output.

Question 3

How to handle errors when using merge-stream?

Accepted Answer

Error handling is not built-in; you need to attach error listeners to individual source streams before merging or handle errors in the merged stream's events. This can add complexity, as errors from one stream might affect the entire merged flow.

Question 4

Can merge-stream preserve the order of streams?

Accepted Answer

No, merge-stream interleaves data from all streams, so the output order is not guaranteed. If you need sequential processing, consider buffering streams separately or using a different merging strategy.

Question 5

Is merge-stream still maintained and updated?

Accepted Answer

Based on the README and GitHub activity, it appears to be stable but not actively developed, as it's a simple utility adapted from event-stream. Check the repository for latest updates or issues before relying on it for critical projects.

Question 6

How to dynamically add streams in a loop with merge-stream?

Accepted Answer

Use the `add` method inside a loop: create a merged stream, iterate over sources, and call `merged.add(stream)` for each. Ensure to manage stream ends properly to avoid memory leaks, as shown in the API documentation.
