Understanding TypeScript in Visual Studio 2017

As a popular language for developing web applications, TypeScript has become increasingly reliable and easier to maintain. By adding type annotations to JavaScript, it adds clarity to a codebase and can streamline development. However, it’s important to know which version of TypeScript is installed, especially when working on a project in Visual Studio 2017.

Method 1: Check the Installed TypeScript Version in Visual Studio

1. Open your TypeScript project in Visual Studio
2. Open the “Solution Explorer” window from View → Solution Explorer or use the shortcut key “Ctrl + Alt + L”
3. Right-click on the project name and select “Properties” from the context menu
4. In the “Project Designer” window, select the “TypeScript Build” tab
5. In the “TypeScript Version” section, you can see which TypeScript version is currently installed in your project

Method 2: Check the Global TypeScript Version Installed on Your Computer

If you have multiple TypeScript projects and want to know the version of TypeScript installed on your computer, you can follow these steps:

1. Open a command prompt window by pressing the “Windows” key and typing “cmd”
2. Type `tsc -v` and press “Enter”. This will display the current version of the TypeScript compiler installed on your computer
3. You can also use the “npm” command to check the installed version.
• Type `npm list -g typescript` and press “Enter”. This will display the global TypeScript version installed on your computer

Method 3: Check the TypeScript Version in Your Package.json File

If you’re using a package manager like NPM or Yarn, you can also check the TypeScript version by looking at the “package.json” file in your project’s root directory.

1. Open the “Solution Explorer” window from View → Solution Explorer or use the shortcut key “Ctrl + Alt + L”
2. Right-click on the project name and select “Open Folder in File Explorer” from the context menu
3. Locate the “package.json” file and open it in a text editor
4. Look for the `”typescript”` entry in the `”dependencies”` or `”devDependencies”` section. The version number specified here is the TypeScript version used in your project.

In conclusion, checking the TypeScript version in Visual Studio 2017 is easy, and it’s essential to ensure compatibility with other dependencies and project requirements. By using any of the three methods outlined above, you can quickly check and confirm the TypeScript version installed or used in your project. Keep coding and enjoy the burst of energy that TypeScript brings to the table.
