+      {
+        name = "@vue/typescript-plugin",

+  filetypes = {
+    "javascript",

+    "vue",
+  },

+
+`location` MUST be defined. If the plugin is installed in `node_modules`,
+`location` can have any value.
+
+`languages` must include `vue` even if it is listed in `filetypes`.
+
+`filetypes` is extended here to include Vue SFC.
