setupComponent

Stability: experimental ⚠️ Experimental feature, use at your risk

TIP

If you're using setupComponent, then defineRender cannot be disabled.

Files in node_modules will not be ignored by default.

With defineSetupComponent, <script setup> code can be put in pure JS/TS(X) without Volar extension.
