How does it work?

A VS Code extension's offline install package (VSIX) is available at:

https://${publisher}.gallery.vsassets.io/_apis/public/gallery/publisher/${publisher}/extension/${extension name}/${version}/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage

Take the syntax highlight extension for Vue.js as an example:

https://marketplace.visualstudio.com/items?itemName=liuji-jim.vue
  • The itemName query is a composition of publisher and extension name, separated with a dot.
  • The publisher is liuji-jim.
  • The extension name is vue.
  • The latest version number is in More Info section on the right side.

So the package can be downloaded via this URL:

https://liuji-jim.gallery.vsassets.io/_apis/public/gallery/publisher/liuji-jim/extension/vue/0.1.3/assetbyname/Microsoft.VisualStudio.Services.VSIXPackage
