The encryption and compression streams are transform streams, which represent duplex streams where the output is in some way computed from the input. The events mentioned above make this situation ideal for using the EventEmitter pattern. If the error argument is null, then the operation was successful.

For example, we can require some native modules: The error event is triggered in case an error occurs. For a more in-depth guide on streams, check out the stream-handbook.

If it encounters an error, it will invoke the callback only once. We can inspect scopes, variables, object properties. We have not only learned how to setup Node, but also core concepts such as callbacks, events and streams.

If you have any problems or further questions, I would be happy to jump on an AirPair and help you work through them. In the last part of the article we tackled production topics such as error handling, debugging, and creating practical applications.

That will show you the full list of versions and also the current and default versions, such as the following: This means it can handle concurrent operations without multiple threads of execution, so it can scale pretty well. The connect event is emitted when the client has successfully connected to the IRC server.

We will have to require the module at the beginning of the file and then wrap the error when invoking the callback: A data event at a regular interval, representing the memory usage in bytes An error event, in case the memory exceeds a certain limit imposed The MemoryWatcher class will look like the following: The EventEmitter pattern allows implementors to emit an event to which the consumers can subscribe if they are interested.

The readFiles function will loop over the file paths and read the content for each. Either way you should attach an error event handler: When the user visits http: IO is a realtime framework that enables bi-directional communication between web clients and the server.

You can read more on CPS here. You can specify tarballs or git repositories as dependencies. We can step over, step in, step out, resume continue. That means that there are two possible scenarios: Node is single-threaded and uses a concurrency model based on an event loop.I have a REST API server which is running on one VM1.

On other VM2 machine I have built a node js server which is running as proxy. On the same VM2 machine I have application (hosted with apache wh. Okay I figured it out, I had "" after these lines of code and that was the problem. is a non-blocking async platform. In your case,; is an Async method, therefore is called before 'write' is complete. @cjihrig @a0viedo I also agree that we should fix the documentation not to use mint-body.comResponse in the "write after end" example.

Fixing the bug in the code would break backward compatibility, in the sense that a given program that is working with the current stable version could break with a new one containing this fix. I have a basic web server with and a root-directory where files are stored.

So what I'am doing is var path =; getHtmlFile = function(req,res){ mint-body.comle('html'+. Join GitHub today. GitHub is home to over 28 million developers working together to host and review code, manage projects, and build software together.
