Is there an extension for Visual Studio Code that provides IntelliSense in an Angular HTML template after you've instantiated an associated class with fields and bound it to that HTML template (inl. Generating a boilerplate angular app (v11) with ng new test-app I am unable to get useful stack traces when debugging with Visual Studio Code. How can I set this up? Repro: // launch.json // Use IntelliSense to learn about possible attributes. // Hover to view descriptions of existing attributes.
My primary goal is to get VSCode intellisense to work with AngularJs.
I’m working on a new application and I’m developing it with AngularJS (Angular 1). I’m also using VSCode (Visual Studio Code) as the IDE. My understanding is that VSCode should provide intellisense for JavaScript code, which it does. In the following image, you can see that VSCode provides intellisense for the variable “d”. VSCode is smart enough to see that this is a string and displays a list of string functions to select from.
Since I’m developing with AngularJS, I would like to have intellisense here also. In the index.html page, I have reference to my AngularJs library, but in my JavaScript file intellisense is not working as expected.
To get intellisense working for AngularJS in VSCode. The following steps need to occur
- Install node.js typings package globally
- Run typings and install AngularJS types
- Create a jsconfig.json file
Assumptions of reader
- Have knowledge of node.js and npm
Tools and version
- node.js 6.2.1
- npm 3.9.5
- Visual Studio Code 1.2
- Windows
1. The Situation
I’m creating an AngularJS application. I have two files index.html and module.js. The index.html file references angular.js library and module.js. The module.js file is where the JavaScript and Angular 1.5 component will live.
By default, VSCode provides intellisense for JavaScript. In the following image you will notice that the variable “d” is a string and that VSCode provides intellisense based on the context of “d” being a string.
In module.js, when I enter “angular.” I expect that intellisense to display a list of AngularJS methods and properties, but as you can see in the image below, this does not occur. My goal in this blog post is to have intellisense display AngularJS methods and properties.
2. Install typings package
The typings package needs to be installed. Since this package will be used for this solution and others. I want to install it globally. First lets’ see what packages are installed currently on the computer.
To figure out what packages are installed globally, run the following command.
npm list -g –depth=0
This command will return all packages at a root depth and not include any children or dependencies of the base packages.
As we can see the typings package has not been install. Let’s install it globally.
npm install -g typings
Now that we installed typings it should now be available to use. Notice the version of typing is 1.3.0.
3. Install AngularJS types
When I initially attempted to install angular typings, I received the following error (see image). This worked just a few days ago. But I install typings 1.3.0. and my typing install didn’t use the same format as pre typings 1.0 used. You can read more about that here Updating Typings From 0.x to 1.0?
To install angular typings, I had to enter the following command:
typings install dt~angular –save –global
When the angular typing is installed the typings.json file and a folder called typings should be created. See image below for more information .
4. Create a jsconfig.json file
Now create an empty jsconfig.json file.
If we were using TypeScript and transpiling code, then this file would contain configuration. But since we are only need intellisense to work, this file can remain empty
5. Validate if Intellisense is working for Angular
Go back to the module.js file. Enter “angular.”. The intellisense should now display AngularJS methods and properties.
Resources
Visual Studio Code (VS Code) is an awesome and free (Open Source) code editor that allows you to build and debug any modern web applications.
VS Code provides built-in intellisense (code completion) for JavaScript, TypeScript, C#, … just hit CTRL+SPACE and have your code auto-complete!
IntelliSense for Angular Directives (HTML)
VS Code has native support for built-in Angular directives in IntelliSense within HTML tag.
IntelliSense for Angular API (Js Code)
Angular Intellisense Visual Studio Code Not Working
VS Code has no out of the box intellisense for Angular code:
But with some setup you can get it!
VS Code uses type definition files (.d.ts) from the DefinitelyTyped project, which provides typings files for all major JavaScript libraries and environments.
Typings files are managed using Typings, the TypeScript Definition manager.
Notes:
- You no longer need to add the ///
to all your .js files! - You also no longer want to use tsd as it has been deprecated.
Instead, we just need a jsconfig.json file at the root directory of your project.
1. jsconfig.json
Create an empty jsconfig.json at the root of your project. You need this jsconfig.json file to get cross-file IntelliSense to work.
2. Install Typings
npm install typings –D
Assuming you have a package.json file, the –D argument will have Typings listed as a dev dependency.
3. Grabs the typings files from the Definitely Typed repository
Visual Studio Code Angular Intellisense
typings install angular –ambient –save
How To Get Angular Intellisense In Visual Studio Code
This will create a typings.json file and a typings folder with the .d.ts files.
Now open a js file and you should have Angular IntelliSense working!
Hopefully this will help you have a great IntelliSense experience when using Angular in Visual Studio Code!
