[[vue-codemirror]]を使ってやってみる。
```console
bun add codemirror vue-codemirror
```
`entrypoints/top/main.ts`
```ts
// 中略
// CodeMirror
import VueCodemirror from "vue-codemirror";
import "codemirror/lib/codemirror.css";
import "codemirror/mode/javascript/javascript.js";
import "codemirror/keymap/vim.js";
createApp(App)
.use(vuetify)
.use(Vue3Toastify, { autoClose: 1000 })
.use(pinia)
.use(VueCodemirror)
.mount("#app");
```
