A Vue 3 development guide for the Composition API, a way to organise component logic with reusable reactive functions. It also covers TypeScript, component macros, and built-in Vue components.

Use it when writing Vue single-file components, defining props and events, managing reactive state, or using Transition, Teleport, Suspense, and KeepAlive.

It keeps Vue code consistent by choosing one component style and setting practical rules for types, reactivity, and performance.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00053	$0.00620
Opus 5.5	$0.00021	$0.00248
Sonnet 5.5	$0.00011	$0.00124
Haiku 4.5	$0.00005	$0.00062

Security

Grade A, and why

vue scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to vue — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 85 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Vue

Based on Vue 3.5. Always use Composition API with <script setup lang="ts">.

Preferences

Prefer TypeScript over JavaScript
Prefer <script setup lang="ts"> over <script>
For performance, prefer shallowRef over ref if deep reactivity is not needed
Always use Composition API over Options API
Discourage using Reactive Props Destructure

Quick Reference

Component Template

<script setup lang="ts">
import { ref, computed, watch, onMounted } from 'vue'

const props = defineProps<{
  title: string
  count?: number
}>()

const emit = defineEmits<{
  update: [value: string]
}>()

const model = defineModel<string>()

const doubled = computed(() => (props.count ?? 0) * 2)

watch(() => props.title, (newVal) => {
  console.log('Title changed:', newVal)
})

onMounted(() => {
  console.log('Component mounted')
})
</script>

<template>
  <div>{{ title }} - {{ doubled }}</div>
</template>

Key Imports

// Reactivity
import { ref, shallowRef, computed, reactive, readonly, toRef, toRefs, toValue } from 'vue'

// Watchers

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
