How can I determine which version of TypeScript is utilized by Visual Studio Code, and what steps should I follow to update it to a newer version?

anonymous user

I’ve been diving into TypeScript recently and am using Visual Studio Code for my projects. However, I keep hearing chatter about different TypeScript versions and how some cool features are only available in the latest ones. It’s got me wondering how to check what version I’m currently running and, more importantly, how to update it if it’s not the latest.

So, here’s my dilemma: I’ve been working on this project, and one of my buddies mentioned that I might be missing out on some nice type-checking features that could really streamline my work. I fired up Visual Studio Code and started searching for where I could find this information. But honestly, I got a bit lost. I figured it must be somewhere in the settings or maybe in the terminal, but I didn’t quite hit the mark.

Has anyone else dealt with this? How do I go about checking which version of TypeScript is being utilized by my Visual Studio Code? I’ve seen mentions of “workspace version” and “VS Code version,” which has thrown me off a bit. Do I need to know both, or is it just one that matters more?

And then there’s the kicker: once I find out what version I’m using, what’s the actual process to update it to the latest? I’ve heard that sometimes the update can be done seamlessly through the extensions panel, but other times, it seems like I need to mess around in the command line. It’s a bit daunting!

If anyone can share the step-by-step process, I’d really appreciate it. Like, do I have to run a specific command in the terminal, or is it just clicking a few things in the UI? And is there anything I need to watch out for to avoid breaking my project?

Thanks in advance for any help! I’m not super tech-savvy, but I’m eager to learn and make my coding experience smoother.

      TypeScript Version Check and Update Guide

      Checking and Updating TypeScript in Visual Studio Code

      First things first, let’s figure out what version of TypeScript you have:

      Step 1: Check the TypeScript Version

      1. Open your project in Visual Studio Code.
      2. Open the integrated terminal with Ctrl + ` (the backtick key).
      3. In the terminal, type the following command and hit enter:

        4. npx tsc -v

      4. This will show you the version of TypeScript that’s currently being used in your project!

      Step 2: Understand ‘Workspace Version’ vs ‘VS Code Version’

      What your buddy is talking about with “workspace version” refers to the TypeScript version installed in your project. This can be different from the TypeScript version that’s bundled with VS Code. So, focus on the workspace version for your current project.

      Step 3: Updating TypeScript

      If you find that your version is out of date and you want to update it, here’s how you can do that:

      1. In the terminal, type this command to install the latest version of TypeScript:

        2. npm install typescript@latest --save-dev

      2. This will update TypeScript in your project.

      Bonus: Updating via Extensions Panel (if you have TypeScript extension)

      1. Check if the TypeScript Extension is installed by clicking on the Extensions icon in the Activity Bar.
      2. If there’s an update available for it, you’ll see an update button next to it. Just click that!

      Things to Watch Out For

      After updating, it’s always good practice to check your code. Sometimes, new features might cause some earlier functionalities to behave differently. Run your tests and ensure everything works as expected.

      Learning new stuff is all part of the fun! Happy coding!

      To check the TypeScript version you’re currently using in Visual Studio Code, you can follow a couple of straightforward steps. First, open the integrated terminal in VS Code by selecting Terminal from the top menu and then New Terminal. Once the terminal is open, simply type tsc -v and press Enter. This command will reveal the TypeScript version installed globally on your machine. Alternatively, you may want to check the workspace version by navigating to the Versions section in the TypeScript status bar, located at the bottom of the VS Code window. If it shows ‘Use Workspace Version’, that indicates you are using the TypeScript version from your project, which can differ from your global installation.

      To update TypeScript to the latest version, you can do this either via the command line or through the extensions panel. To use the command line, first make sure you are in your project directory, then run npm install typescript@latest to update it to the latest version available in your project’s dependencies. If you want to update the global version, you would use npm install -g typescript@latest. If you prefer using the UI, you can go to the Extensions panel (by clicking on the Extensions icon on the sidebar) and search for ‘TypeScript’. If an update is available, you should see an update button. However, be cautious: before updating, ensure that your existing code is backed up or that you’re using version control, as there might be breaking changes in new TypeScript releases that could affect your current project.
