To get a taste of what is possible, Socket.io provides two demos to show it’s possible use-cases. This library uses Engine.IO for building the connection. To ensure this Socket.io uses WebSockets to establish a connection between the client’s browser and the server. Socket.io is a Node.js library made to help make real-time communication between computers possible. Since both the timers are started together, they complete together and therefore take same amount of time. When the timer completes it’s execution taking 5 seconds, it calls the function and prints done on the console. Instead, it moves on to call the second my_io_task(), starts the timer and leaves it there. It does not wait for the response from the function. The first call to my_io_task() starts the timer and leaves it there. Node.js takes less time because of its non-blocking I/O model.

The Python code takes 10 seconds to execute while the Node.js code takes only 5 seconds. Let us assume that a particular I/O task takes 5 seconds to execute, and that we want to perform this I/O twice in our code.īoth look similar, but the time taken to execute are different. Node.js uses callback functions to handle such requests. We know that I/O tasks take much longer than processing tasks. We can also declare our own custom events and make Node.js listen for those events. Events can be anything from a click to a HTTP request. This means that Node.js waits for certain events to take place. Node.js also uses this super-fast engine to interpret JavaScript files.

Google Chrome uses the V8 engine, which is built using C++.

Node.js is a JavaScript runtime built on Chrome’s V8 JavaScript engine.Įvery browser has a JavaSript engine built in it to process JavaScript files contained in websites.

If both commands work, your installation was a success, and you can start using Node.js! More info on Node.jsĪccording to its GitHub repository, Node.js is: Node.js is an open-source, cross-platform, JavaScript runtime environment. The console should respond with a version string. Run command prompt or powershell and input the following to test it out: > node -v If you installed under the default configuration, Node.js should now be added to your PATH. Restart your computer after the installation is complete. This should be the default configuration.

Follow the prompts to select an install path and ensure the npm package manager feature is included along with the Node.js runtime. Once you have selected a version meets your needs, run the installer.

The LTS version foregos feature changes to improve stability, but receives patches such as bug fixes and security updates.

The Current version receives the latest features and updates more rapidly.

You will have the choice between the LTS (Long Term Support) or Current version.
