The
'finish' event in a Writable Stream is emitted after the Calling of writable.end() method when all the data is being flushed to the hidden system.
Syntax:
Event: 'finish'
Return Value: If the writable.end() method is being called before then this event is emitted else its not emitted.
Below examples illustrate the use of
'finish' event in Node.js:
Example 1:
Output:
hi
program is ended.
Write is completed.
In the above example, writable.end() method is called before the finish event so it is emitted.
Example 2:
Output:
hi
program is ended.
So, here writable.end() function is not called so the finish event is not executed.
