For example, you can require http and get full IntelliSense against the http class as you type in Visual Studio Code. Even more interesting, you can get full IntelliSense against the Node.js framework.

Notice how VS Code understands that _dirname is a string. Open the file app.js and hover over the Node.js global object _dirname. Visual Studio Code will make you more productive in developing these types of applications by providing great code editing and navigation experiences.

The Node.js and Express documentation does a great job explaining how to build rich applications using the platform and framework.
#Node js visual studio code tutorial install#
Note: If you've been using the VS Code integrated terminal to install the Express generator and scaffold the app, you can open the myExpressApp folder from your running VS Code instance with the File > Open Folder command. Install the Express Generator by running the following from a terminal: Tip: To test that you've got npm correctly installed on your computer, type npm -help from a terminal and you should see the usage documentation. The Express Generator is shipped as an npm module and installed by using the npm command-line tool npm. You can scaffold (create) a new Express application using the Express Generator tool. An Express applicationĮxpress is a very popular application framework for building and running Node.js applications. You can delete the "Hello" folder if you want as it is not required for the rest of the walkthrough. Note: We're done with the "Hello World" example so navigate out of that folder before you create an Express app. Now that you've seen VS Code in action with "Hello World", the next section shows using VS Code with a full-stack Node.js web app. Notice that VS Code displays a different colored Status Bar to indicate it is in Debug mode and the DEBUG CONSOLE is displayed. Your breakpoint will be hit and you can view and step through the simple application.

You can now click Debug toolbar green arrow or press kb() to launch and debug "Hello World". To start debugging, select the Run View in the Activity Bar: To set a breakpoint in app.js, put the editor cursor on the first line and press kb() or click in the editor left gutter next to the line numbers. Let's try debugging our simple Hello World application. Debugging Hello WorldĪs mentioned in the introduction, VS Code ships with a debugger for Node.js applications. View > Terminal ( kb() with the backtick character) will open the integrated terminal and you can run node app.js there:įor this walkthrough, you can use either an external terminal or the VS Code integrated terminal for running the command-line tools. You can run Node.js directly from there and avoid switching out of VS Code while running command-line tools. VS Code has an integrated terminal which you can use to run shell commands. You should see "Hello World" output to the terminal and then Node.js returns. Let's get started by creating the simplest Node.js application, "Hello World".Ĭreate an empty folder called "hello", navigate into and open VS Code: To learn more, go to Developing in WSL or try the Working in WSL tutorial.

When coupled with the Remote - WSL extension, you get full VS Code editing and debugging support while running in the context of WSL.
#Node js visual studio code tutorial windows#
You can run Linux distributions on Windows and install Node.js into the Linux environment. Windows Subsystem for Linux: If you are on Windows, WSL is a great way to do Node.js development. See Installing Node.js via package manager to find the Node.js package and installation instructions tailored to your version of Linux. Linux: There are specific Node.js packages available for the various flavors of Linux. To test that you have Node.js installed correctly on your computer, open a new terminal and type node -version and you should see the current Node.js version installed. You'll need to open a new terminal (command prompt) for the node and npm command-line tools to be on your PATH. The Node Package Manager is included in the Node.js distribution. To get started in this walkthrough, install Node.js for your platform. However, to run a Node.js application, you will need to install the Node.js runtime on your machine. Visual Studio Code has support for the JavaScript and TypeScript languages out-of-the-box as well as Node.js debugging. Node.js is the runtime and npm is the Package Manager for Node.js modules. Node.js is a platform for building fast and scalable server applications using JavaScript.
