Visual Studio Code Extension offline installation

Recently I read about the Teams Toolkit to develop Teams apps in Visual Studio Code. I immediately wanted to have a look at it, but I did not find the extension inside VS Code. So I had to perform a Visual Studio Code Extension offline installation. I want to show you in this article, how this worked out for me. This workaround also works for VS Codium, which I used for the screenshots in this blog post.

The first thing you need to do is to find the extension in the Visual Studio Code Marketplace. Here you can search and find any available extension, no matter if your VS Code or VS Codium discovers it or not:

Extension available in the marketplace but not in VS Codium

Good about the marketplace is the fact that each extension contains a hidden Download link. This enables you to perform offline installations or centralized distribution:

Download a VS Code extension from the marketplace

This downloads a vsix file to your desktop. This is the offline installer. This needs to be added to Visual Studio Code now. Open the menu View -> Extensions (or hit Ctrl+Shift+X) and open the really shy menu to import an own file:

Visual Studio Code Extension offline installation
manually install extension

Choose the just downloaded vsix file and VS Code will do the rest for you. This will take only some seconds and then you will see the extension was installed:

Extension was successfully installed

The new app also integrates to the sidebar in VS Code:

That’s it – now you are ready to go with your recently installed extension and develop cool software with a beautiful VS Code or Codium environment 🙂
