The
stream.Writable close Event is an inbuilt application programming interface of Stream module which is used to emit when the stream and any of its hidden resources (for example, a file descriptor) is being closed. This event implies that no further events will be emitted, plus no further computation will take place.
Syntax:
Event: 'close'
Return Value: If the writable.destroy() method is being called or a file descriptor is being closed after this event then this event is emitted else it's not emitted.
Below examples illustrate the use of
stream.Writable close Event in Node.js:
Example 1:
Output:
GeeksforGeeks
program is ended.
No further operations will be performed!
In the above example, writable.destroy() method is called after the close event so it is emitted.
Example 2:
Output:
GeeksforGeeks
program is ended.
So, here writable.destroy() function is not called so the close event is not executed.
