What is Vue.JS
For a richer Vue.js development environment, you can install the Vetur extension which supports Vue.js IntelliSense, code snippets, formatting, and more.
We'll be using the Vue CLI for this tutorial. If you are new to the Vue.js framework, you can find great documentation and tutorials on the vuejs.org website.
npm is included with Node.js which you can install from Node.js downloads. Tip: To test that you have Node.js and npm correctly installed on your machine, you can type node --version and npm --version.
To install the vue/cli , in a terminal or command prompt type:. This may take a few minutes to install.
You can now create a new Vue.js application by typing:. where my-app is the name of the folder for your application.
[Vue VSCode Snippets] focuses on developer ergonomics from the point of Vue of real world use. Included are the pieces I personally get sick of typing, and boilerplate that is helpful to stub out quickly.Source
It may take a few minutes to create the Vue application and install its dependencies. Let's quickly run our Vue application by navigating to the new folder and typing npm run serve to start the web server and open the application in a browser:.
You should see "Welcome to your Vue.js App" on http://localhost:8080 in your browser. You can press Ctrl+C to stop the vue-cli-service server. To open your Vue application in VS Code, from a terminal (or command prompt), navigate to the my-app folder and type code .:.
VS Code will launch and display your Vue application in the File Explorer. Now expand the src folder and select the App.vue file.
Vue.JS vs other libraries
You'll notice that VS Code doesn't show any syntax highlighting and it treats the file as Plain Text as you can see in the lower right Status Bar.
You'll also see a notification recommending the Vetur extension for the .vue file type. The Vetur extension supplies Vue.js language features (syntax highlighting, IntelliSense, snippets, formatting) to VS Code.
From the notification, press Install to download and install the Vetur extension. You should see the Vetur extension Installing in the Extensions view.
Once the installation is complete (may take several minutes), the Install button will change to the Manage gear button.
Now you should see that .vue is a recognized file type for the Vue language and you have language features such as syntax highlighting, bracket matching, and hover descriptions.
As you start typing in App.vue, you'll see smart suggestions or completions both for HTML and CSS but also for Vue.js specific items like declarations (v-bind, v-for) in the Vue template section:.
and Vue properties (methods, computed) in the scripts section:. VS Code through the Vue extension language service can also provide type definition information in the editor through Go to Definition (F12) or Peek Definition (⌥F12 (Windows Alt+F12, Linux Ctrl+Shift+F10)).
Put the cursor over the App, right click and select Peek Definition. A Peek window will open showing the App definition from App.js.
Press Escape to close the Peek window. Let's update the sample application to "Hello World!" In App.vue replace the HelloWorld component msg custom attribute text with "Hello World!"
How to get help
Once you save the App.vue file (⌘S (Windows, Linux Ctrl+S)), restart the server with npm run serve and you'll see "Hello World!"
Leave the server running while we go on to learn about Vue.js client side debugging. Tip: VS Code supports Auto Save, which by default saves your files after a delay. Check the Auto Save option in the File menu to turn on Auto Save or directly configure the files.autoSave user setting.
Linters analyze your source code and can warn you about potential problems before you run your application.
