JWT Decoder for Vue.js Developers

Quick Answer

DevToolHQ's jwt decoder works great alongside Vue.js. Use it to quickly jwt decoder during development, then integrate the pattern into your Vue.js codebase using the code example below.

Use Cases in Vue.js

  • 1.Verify user authentication tokens
  • 2.Debug token expiration and claims
  • 3.Implement role-based access control from JWT claims
  • 4.Validate tokens from third-party auth providers

Vue.js Code Example

Vue.js
<script setup lang="ts">
import { ref, computed } from 'vue'

const token = ref('')

const payload = computed(() => {
  try {
    const [, b64] = token.value.split('.')
    return JSON.parse(atob(b64.replace(/-/g, '+').replace(/_/g, '/')))
  } catch { return null }
})

const expired = computed(() => {
  if (!payload.value?.exp) return false
  return Date.now() / 1000 > payload.value.exp
})
</script>

<template>
  <textarea v-model="token" placeholder="Paste JWT here..." />
  <pre v-if="payload">{{ JSON.stringify(payload, null, 2) }}</pre>
  <p v-if="expired" style="color:red">⚠️ Token expired</p>
</template>
