If your project requires Typescript support, you will also need to install the '@types/codemirror' dependency.

Register global component

Do not recommend global registration components, which will result in the type of prompt on the template that cannot be properly obtained.

main.js:

import { createApp } from "vue";
import App from "./App.vue";
import { InstallCodeMirror } from "codemirror-editor-vue3";

const app = createApp(App);
app.use(InstallCodeMirror);
app.mount("#app");

The global registered component name is Codemirror or you can customize a component name, for example:

app.use(InstallCodeMirror, { componentName: "customName" });
