VS Code uses the TypeScript language service for code intelligence ( IntelliSense) and it has a feature called Automatic Type Acquisition (ATA). You can click the information button ( i) to see a flyout with more documentation. Items such as variables, classes and Angular decorators are a few examples where you'll be presented with this information.Īs you start typing in, you'll see smart suggestions and code snippets. You'll notice that VS Code has syntax highlighting for the various source code elements and, if you put the cursor on a parenthesis, the matching bracket is also selected.Īs you hover your mouse over text in the file, you'll see that VS Code gives you information about key items in your source code. Now expand the src\app folder and select the file.
To open your Angular application in VS Code, open another terminal (or command prompt) and navigate to the my-app folder and type code. We'll leave the web server running while we look at the application with VS Code. You should see "Welcome to app!!" on in your browser. Let's quickly run our Angular application by navigating to the new folder and typing ng serve to start the web server and open the application in a browser: cd my-app ng serve

This may take a few minutes to create the Angular application in TypeScript and install its dependencies. My-app is the name of the folder for your application. You can now create a new Angular application by typing: ng new my-app To install the Angular CLI, in a terminal or command prompt type: npm install -g may take a few minutes to install.
Tip: To test that you have Node.js and npm correctly installed on your machine, you can type node -version and npm -version. npm is included with Node.js which you can install from Node.js downloads. To install and use the command line interface as well as run the Angular application server, you'll need the Node.js JavaScript runtime and npm (the Node.js package manager) installed. We'll be using the Angular CLI for this tutorial. The Visual Studio Code editor supports Angular IntelliSense and code navigation out of the box.
