How To Fix Visual Studio Code IntelliSense Loading Infinitely

Continuing with weird errors you might encounter in JavaScript world, I have another one: Visual Studio Code IntelliSense loading infinitely 😀 Solution included, of course!

The symptoms of this issue are putting your mouse on something where you’d expect the IntelliSense guidelines, but instead you only see the “Loading…” text.

In this short article, I’m sharing the reason of this issue and my way of fixing it.

How VS Code Infinite IntelliSense Loading Looks Like

This is what I struggled with:

As you can see, I didn’t get any IntelliSense while hovering my mouse on various elements in the editor.

A similar thing happened when I tried to use Go to References (or Shift + F12 on Windows) for any object:

As you can see, the loading bar at the top of VS Code was showing progress infinitely.

Let’s now see how to fix this annoying issue 😉

Fixing Visual Studio Code IntelliSense Loading Infinitely

After quite long investigation, I finally found the reason. It turned out that sometimes your Visual Studio Code might be using a different TypeScript version than your workspace uses. In my case, it was exactly the cause of the infinite loading problem 🧐

In order to fix it, use TypeScript: Select TypeScript Version... command. You can access commands with Ctrl + Shift + P on Windows or ⇧⌘P on Mac:

Visual Studio Code: command palette view, "TypeScript: Select TypeScript Version" command

Select this command and tell Visual Studio Code to use the workspace version of TypeScript:

As you can see on the screenshot above, in my case the VS Code’s TypeScript version was 4.8.2, while the workspace version was 4.8.3. Changing it to use the newer, workspace version solved the problem. Visual Studio Code IntelliSense loading infinitely issue was gone 🎉

If it doesn’t work straightaway, you might need restarting your VS Code editor.

I hope that worked for you and saved you some hours of debugging and exploring StackOverflow 🙂

Didn’t work for me either. The only thing that works, and something I have to do several times per day, is close and reopen VSCode.

Struggled with this on a project for a week! For me, the culprit was the Intellisense was scanning files not related to the project. Specifically, I had some code that was pulling data from the AWSCLI and so I didn’t have to inspect the results every time, I saved it as a json file into a junk folder within my project folder. Then to compound the problem I used gron to make it an easy-to-read .js file. So picture two giant javascripty-looking files in the project folder. These gave ‘Intellisense Loading’ a reason to lock at 100% cpu and never finish. After exiting VSCode I would have to kill the pids of these hung processes.

Ultimately I moved my scratch .js and .json files into a hidden folder (this is linux so I just put a . in front of the foldername), closed VSCode, killed the pids of the hung processes one more time, and then restarted VSCode.
