Transform stream which filters stream data according to user-defined conditions.
$ npm install flow-find
var eventStream = require( 'event-stream' ),
fStream = require( 'flow-find' );
// Create some data...
var data = new Array( 1000 );
for ( var i = 0; i < data.length; i++ ) {
data[ i ] = Math.random() * 100;
}
// Create a readable stream:
var readStream = eventStream.readArray( data );
// Create a new find stream:
var stream = fStream()
.filter( function ( d ) {
return ( d >= 95 );
})
.stream();
// Create the pipeline:
readStream.pipe( stream )
.pipe( eventStream.map( function( d, clbk ) {
clbk( null, d.toString() );
}) )
.pipe( process.stdout );
Unit 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:
$ mocha
All new feature development should have corresponding unit tests to validate correct functionality.
