+import { defineConstCore } from 'vite-plugin-global-const'
+
+export function customPlugin() {
+  return {
+    name: 'vite-plugin-custom',
+    config: () => {
+      const defineConst = defineConstCore({
+        YourConst: true
+      })
+      return {
+        define: {
+          ...defineConst
+        }
+      }
+    }
+  }
+}
