Transform stream factory to evaluate an exponential function for each numeric data value.
$ npm install flow-expTo create a stream factory,
varexpStream=require('flow-exp');// Create a new factory:vareStream=expStream();To create a new exponential stream,
varstream=eStream.stream();Methods are chainable.
expStream().stream().pipe(/* writable stream */);vareventStream=require('event-stream'),eStream=require('flow-exp');// Create some data...vardata=newArray(1000);for(vari=0;i<data.length;i++){data[i]=Math.round(Math.random());}// Create a readable stream:varreadStream=eventStream.readArray(data);// Create a new exponential stream:varstream=eStream().stream();// Pipe the data:readStream.pipe(stream).pipe(eventStream.map(function(d,clbk){clbk(null,d.toString()+'\n');})).pipe(process.stdout);To run the example code from the top-level application directory,
$ node ./examples/index.jsUnit tests use the Mocha test framework with Chai assertions.
Assuming you have installed Mocha, execute the following command in the top-level application directory to run the tests:
$ mochaAll new feature development should have corresponding unit tests to validate correct functionality.
