The full application, at this point is this: // RequirementsĪpp. With WebStorm, you can debug various kinds of applications - client-side applications, Node.js applications, tests, and so on. Although it is setting back the value of the environment variable it isn’t persisted outside of the application, so it really just serves to set up a default value without you having to check for a value and supply a default value when ever it is actually needed. By default it will take the value in the "port" environment variable, and if not found it will default to port 3000 within the scope of the process. ![]() What this is doing is getting the port to run the application on. In both the WebStorm and Visual Studio templates there is a line of code that looks like this: app.set('port', || 3000) Once you’ve clicked on that, your TypeScript code will compile in WebStorm for you automatically. The easiest way is to right-click anywhere on your TypeScript workspace, and right at the bottom of the list that shows is a Compile TypeScript option. It will configure the environment and start the HTTP listener. The next step will be to compile TypeScript in WebStorm. It will bootstrap the Express application. To start with I created a folder with just a package.json file in it, then in a command line I ran npm to install Express: npm install express –save Express "Hello, World!"Īt this stage an app.js file is created. ![]() You can debug applications that are started from WebStorm as well as attach to already running applications. So, my beginner question is as simple as this: how can I configure/set up WS. ![]() Import required modules We use the require directive to load Node.js modules. A Node.js application consists of the following three important components. If I understood correctly, WS supports plain JS, but from all the search Ive made here (and outside) this forum, Ive just found how to set up WS to work with Node.js. Before creating an actual 'Hello, World' application using Node.js, let us see the components of a Node.js application. While both Visual Studio and WebStorm have templates for node.js Express applications in this post (and and subsequent few posts) I’m going to walk through setting up an Express application so that you can see how it fits together. WebStorm helps you run and debug your Node.js applications. Ive just installed WS with the objective of developing a simple DOM manipulation JavaScript file.
