Transform stream factory to chunk streamed data values.
$ npm install flow-chunkifyTo create a stream factory,
varchunkStream=require('flow-chunkify');// Create a new factory:varcStream=chunkStream();This method is a setter/getter. If no numValues is provided, returns the numValues to chunk; default is 1. To set the numValues,
cStream.numValues(10);To create a new chunkify stream,
varstream=cStream.stream();Methods are chainable.
chunkStream().numValues(10).stream().pipe(/* writable stream */);vareventStream=require('event-stream'),cStream=require('flow-chunkify');// Create some data...vardata=newArray(1000);for(vari=0;i<data.length;i++){data[i]=Math.random();}// Create a readable stream:varreadStream=eventStream.readArray(data);// Create a new chunkify stream:varstream=cStream().numValues(10).stream();// Pipe the data:readStream.pipe(stream).pipe(eventStream.map(function(d,clbk){clbk(null,JSON.stringify(d)+'\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 globally 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.
