Maybe something more specific like "Emitted when the ReadStream's underlying file descriptor has been closed" and similarly for WriteStream?

This needs to be prefixed with ####.


Emitted when the stream and any of its underlying resources (a file descriptor, for example) have been closed. The event indicates that no more events will be emitted, and no further computation will occur.

How does this differs from 'end'?
Should a user expect 'close' or 'end' to proceed? Which one happens first?

I will also move this block after 'end', meaning that 'end' is the preferred way of waiting for the end of a stream.

@mcollina

I hesitate to move the 'Event: 'close'' block to after the 'Event: 'end'' block because these events seem to be in alphabetical order for better user experience.

The difference between 'close' and 'end' events:

  1. 'close' event - Whatever it is tied to, for example a stream, it is done now. This event comes from the fs.close() method and is optional. Not all streams emit this event.
  2. 'end' event - Waits for the current data to finish buffering. means no more data will be emitted. This event is tied to the end() function on Streams.


Not all streams will emit the 'close' event.

'close' needs to be surrounded by backticks to match the formatting from the Readable section.
