time-window-stream
concatenate all the data chunks that fall within a time window
example
Every time there is a write on stdin, wait 1 second to buffer up more data and concatenate everything in that 1 second window together:
var timeWindow = ;var through = ;var tw = ;processstdin;
output:
$ (echo -n abc; sleep 0.5; echo -n def; sleep 2; echo -n hi; sleep 0.1; echo -n jkl) | node tw.js
'abcdef'
'hijkl'
'abc'
and 'def'
are only separated by 0.5 seconds, so they get put into the
same chunk. The pause of 2 seconds breaks the chunk and then 'hi'
gets
concatenated to 'jkl'
because only 0.1 seconds elapsed between them.
methods
var timeWindow =
var tw = timeWindow(time, opts={})
Create a new time window through stream tw
that on a write will wait time
milliseconds to concatenate more writes together in the same batch.
If opts.objectMode
is true
, tw
will output arrays of objects with all the
objects that were written during the time window. Otherwise, tw
will output
buffers with the concatenated data written during the time window.
install
