What you’re describing is already possible. Set
vetur.useWorkspaceDependencies: truein settings.json and make sure you have TS 3.7 installed in your project’s node_modules. You can probably even use the new TS 3.8 beta but I haven’t tried yet.Nullish coalescing and optional chaining won’t work in templates though - only in <script> tag.
Should already be fixed in 0.23.0.
