spollack / streamlineLoader.js

Created January 8, 2014 22:38

A thunk to load a single streamline source file (passed as a command line parameter) from vanilla node. Useful for one-offs. A similar approach can be taken to run mocha tests that include streamline code. The use of the optimist package here is pure sugar, and could be skipped if desired. In a typical full app, the main file would do the stream…

	require('streamline').register({
	fibers: true,
	cache: true,
	verbose: true
	});

	var argv = require('optimist')
	.usage('Usage: $0 -r streamlineFilePath')
	.demand(['r'])
	.argv;

example of monkey-patching express to handle streamlinejs middleware. tested under express 2.x, but the same approach should work under express 3.x too.

	var app = express.createServer();
	var verbs = ['get', 'post', 'put', 'delete']; // whatever verbs you want to patch here...
	patchExpressForStreamlineMiddleware(app, verbs, noop);

	// now, you can make a call like this:
	// app.get('/mypath', myStreamlineFunction)
	// and have it work correctly. sequences of middleware will work too:
	// app.get('/mypath2', myStreamlineFunction1, myStreamlineFunction2, myStreamlineFunction3)

example that demonstrates how streamline 0.8.1 in fibers mode is not preserving line numbers when invoking non-streamline functions, if the call spans multiple lines

	/* Generated by streamline 0.8.1 (fibers) - DO NOT EDIT */var fstreamline__ = require("streamline/lib/fibers/runtime"); (fstreamline__.create(function(_) {var test_ = fstreamline__.create(test, 0), foo_ = fstreamline__.create(foo, 0); function test(_) {
	foo(_);
	fstreamline__.invoke(null, bar, [_], 0);
	};

	function foo(_) {
	// set a breakpoint on the next line
	console.log('should not print before breakpoint hit');
	console.log('should print after breakpoint hit');
	}

A script that demonstrates a performance dropoff in streamline between versions 0.6.0 and 0.8.0.

	var zlib = require('zlib');


	test(_);

	function test(_) {

	var startTime = new Date();

	var items = [];

	var zlib = require('zlib');


	var iteration = 0;
	var maxRss = 0;

	(function leak() {

	if (iteration % 1000 === 0) {
	var usage = process.memoryUsage();
