})If you open the controller, you need to import the script in the initialization. vue3 example:
<script setup lang="ts">
import { markdownItDiagramDom } from 'markdown-it-diagram/dom'
import { onMounted } from 'vue'
onMounted(async () => {
// if you want to use mermaid, you need to install mermaid.js
// npm install mermaid
// import mermaid from 'mermaid'
mermaid.initialize({ startOnLoad: false })
await mermaid.run()
// initialize markdown-it-diagram/dom script
await markdownItDiagramDom()
})
</script>
