The second argument accepts optional subprotocols. There is also wss, for secure WebSocket connection the same way https is used for secure HTTP connections.Īttaching some event handlers immediately to the connection allows you to know when the connection is opened, received incoming messages, or there is an error. Ws is the new URL schema for WebSocket connections. Var connection = new WebSocket('ws:///echo', ) Web socket connection can be simply opened using a constructor − In layman terms, there is a persistent connection between the client and the server and both parties can start sending data at any time. The Web Socket specification defines an API establishing "socket" connections between a web browser and a server. For example, a multiplayer shooter game in the browser or any other online game with a real-time component. However, all of these share one problem, they carry the overhead of HTTP, which does not make them well suited for low latency applications. Long polling and the other techniques work quite well. Whenever the server actually has new data, it sends the response. With long polling, the client opens an HTTP connection to the server, which keeps it open until sending response. They go by names such as "Push" or “Comet”. Technologies that enable the server to send the data to a client in the very moment when it knows that new data is available have been around for quite some time. Still, all HTTP communication is steered by the client, which requires user interaction or periodic polling to load new data from the server. Around 2005, AJAX started to make the web feel more dynamic.
A client loads up a web page and then nothing happens until the user clicks onto the next page. In this way, we can find an important note quickly thanks to the label.The Web has been largely built around the request/response paradigm of HTTP. Also, if we right-click on a label, we can manage or add a color to it.
To do this, we just have to type something in the “Search or create label” box and press Enter, and in this way a label will be assigned to the active note. We will use the Note icon at the top of the toolbar or from the Note menu to create a new note.Īt the top of the taskbar we will also find the Labels tab, which we can use to add a label to a note. Once the main menu appears, the interface seems quite complex.

In general, we will use the Full style, although if you prefer to have more space for notes you can choose the Minimum style. For this we will have four interface styles: Minimum, Full, Full vertical and Single column. When we run QOwnNotes the first time, it will ask us to select the Note folder, which is nothing more than the directory where all our notes will be stored. Simple text editor with very useful functions It has notes encryption in AES 256 format, allowing you to use custom encryption methods through Keybase.io or PGP.

It has supports for scripts, as well as an online repository where you can install scripts within the application.
