Know your Node.js (and VS Code)

Continuing with our VS Code Theme, today I've got three items for you (well, one, okay, kind of three, or whatever... )

Node.js Applications with VS Code

Node.js is a platform for building fast and scalable server applications using JavaScript. Node.js is the runtime and NPM is the Package Manager for Node.js modules.

To get started, install Node.js for your platform. The Node Package Manager is included in the Node distribution.

Tip! You can download both the TypeScript and JavaScript versions of the sample application created in this walkthrough from the vscode-samples repository.

Express

Express is a very popular application framework for building and running Node applications. You can scaffold a new Express application using the Express Generator tool, which is typically installed globally on your computer.

...

Great Code Editing Experiences

Close the browser and from a terminal in the myExpressApp folder, stop the Node.js server by pressing CTRL+C. Now launch VS Code.

...

Tip: You can open files or folders directly from the command line. The period '.' refers to the current folder, therefore VS Code will start and open the myExpressApp folder.

The Node.js and Express documentation does a great job explaining how to build rich applications using the platform and framework. Visual Studio Code will make you more productive developing these types of applications by providing great code editing and navigation experiences.

VS Code uses the TypeScript compiler to drive its JavaScript language service, which means we can take advantage of what the compiler can infer about your code. For example, let's create a simple string variable in app.js and send the contents of the string to the console.

...

Open app.js and notice how the warnings no longer appear for__dirname. This is because VS Code now understands what __dirname is, based on the metadata from the node.d.ts file. Even more exciting, you can get full IntelliSense against the Node framework. For example, you can require http and get full IntelliSense against the http class as you type in Visual Studio Code.

Your first Node Express App

...

Debugging your Node Application

In order to run and debug your Node application from within VS Code, you need to configure how the application will be started. To do this, click on the Debug icon in the View Bar on the left of Visual Studio Code.

Your first Node Express App

Click on the Configure gear icon at the top of the Debug view to create a default launch.json file.

...

Next Steps

There is much more to explore with Visual Studio Code, please try the following topics:

  • Debugging - This is where VS Code really shines
  • Editing Evolved - Lint, IntelliSense, Lightbulbs, Peek and Goto Definition and more
  • ASP.NET 5 - End to end sample showing off our ASP.NET 5 and .NET 5 support with a sample app
  • Tasks - Running tasks with Gulp, Grunt and Jake. Showing Errors and Warnings

Mastering Node.js Modules and Packages with Visual Studio Code

Why choose Node.js for your next project? There are tons of reasons to use this server-side application framework, and two of the biggest are packages and modules, key parts of the Node.js foundation. The Node.js online repository, npm, contains just about any code your project might need, and it's easy to plug in that code and to keep it up-to-date. Plus, you can start giving back to the vibrant node ecosystem by sharing the clever things you have built.

Watch experts Jeremy Foster and Chris Kinsman, as they explore packages and modules and the difference between the two. See Visual Studio Code in action, along with cool demos, including a detailed look at real-world packages and how they are structured. Learn how to create and consume modules, how to bundle them into a package, and how easy it is to publish to npm. If you are already working with node and you're familiar with JavaScript, but you're not sure how packages and modules work behind the scenes, take this opportunity to see how the magic comes together!

(NOTE: If you'd like to review Node.js concepts, take a look at the Microsoft Virtual Academy MEAN Stack Jump Start and the popular course, Using Node.js with Visual Studio Code.)
