You can mount it independently on an Nginx server, while other frontend pages can redirect to this mounted interface. (Note to handle cross-origin issues during mounting) Here's an example of frontend redirection to this page:
<el-table-column label="Preview" width="70">
<template v-slot="scope">
<span v-if="scope.row.finish_time !== null">
<a :href="'/cardiacSTLViewer/model.html?dataid='+scope.row.data_id+'&type=1'" target="_blank">Preview</a>
</span>
</template>
</el-table-column>
