Reduce transform stream which returns the median value from a stream of numeric data.
Note: in order to calculate the median exactly, all data must be buffered into memory. As a result, this stream acts as a sink. Use caution when applying the transform to large datasets.
$ npm install flow-median
var eventStream =mStream = ;// Create some data...var data = 1000 ;for var i = 0; i < datalength; i++data i = Math;// Create a readable stream:var readStream = eventStream;// Create a new median stream:var stream = ;// Create a pipeline:readStream;
Assuming you have installed Mocha, execute the following command in the top-level application directory to run the tests:
All new feature development should have corresponding unit tests to validate correct functionality.
