---

This iteration we enabled type acquisition on vscode.dev for JS/TS. This means:

• We can provide intellisense for packages listed in the package.json

• For JS files, we can provide intellisense for imported files even if they aren't in the package.json, i.e. you can type import $ from 'jquery'; and start getting jQuery IntelliSense

With these two features on, we've also enabled semantic error reporting again

Testing

For this test plan item, try out this new support on https://insiders.vscode.dev and make sure it works as expected. Test in Chrome/edge.

Some basic areas to test

• Open a small/medium sized TS project from github

  • You get IntelliSense for the module imports
  • Confirm auto imports work
  • You should get semantic/typings errors
  • You can use go to definition and find all references on types from modules

• Try doing the same but this time opening a folder from your local machine

• Create a loose js file. Try adding an import for a third party library and confirm you get IntelliSense for it after the typings are installed

Known limitations

• Safari currently doesn't support this. The nightly safari should but for

• Currently only tested for small/medium projects. Larger project, such as vscode, will likely work but may take a while to load. We're working on implementing caching to support them better
