+#### `devServerPublicPathRoute` for Vite v5
+
+If using Vite version 5, setting `devServerPublicPathRoute` may be needed if directly referencing public path url assets in components under test. This is due to Cypress using its own public path, `/__cypress/src`, when running component tests. This can be configured within the `component` namespace below if you wish you set your public path to be the same as your app:
+
+```ts
+import { defineConfig } from 'cypress'
+
+export default defineConfig({
+  component: {
+    // If wanting a publicPath the same as the default in Vite 5
+    devServerPublicPathRoute: ''
+  }
+})
+```
