环境变量文件

package.json配置启动项

{

    "build": "nuxt build --dotenv .env.production",
    "build:dev": "nuxt build --dotenv .env.development",
    "build:test": "nuxt build --dotenv .env.test",
    "dev": "nuxt dev --dotenv .env.development --exec",
    "test": "nuxt dev --dotenv .env.test --exec",
    "prod": "nuxt dev --dotenv .env.production --exec",

两种方式

<template>
  <div>
    {{ env.VITE_APP_BASE_API }}

  </div>
</template>

<script lang="ts" setup>
const env = import.meta.env;

const config = useRuntimeConfig()
const APP_BASE_API = config.public.APP_BASE_API
</script>
