Vue Templates

Vue templates compile to render functions. They support interpolations, directives, and components. This lesson covers practical patterns, syntax, and mistakes to avoid.

Template Syntax

Vue templates compile to render functions. They support interpolations, directives, and components.

Keep logic light in templates — move complexity to computed/methods/composables.

<p>{{ message }}</p>
<p v-once>{{ message }}</p>
<div v-html="trustedHtml"></div> <!-- careful -->

Interpolation, v-once, and the XSS-sensitive v-html.

Must Know

mustache, v-bind, v-on, v-if, v-for, slots

Prefer Vue 3 + Composition API.
Use script setup for SFCs.
Keep components focused.
Lean on official docs.
