If you wish to reference environment variables within your Nuxt 3 app, you will need to use runtime config.
When referencing these variables within your components, you will have to use the useRuntimeConfig composable in your setup method (or Nuxt plugin).
In the server/ portion of your app, you can use useRuntimeConfig without any import.
runtimeConfig property of the nuxt.config file.process.env to useRuntimeConfig throughout the Vue part of your app.export default defineNuxtConfig({
runtimeConfig: {
// Private config that is only available on the server
apiSecret: '123',
// Config within public will be also exposed to the client
public: {
apiBase: '/api',
},
},
})
<script setup lang="ts">
const config = useRuntimeConfig()
// instead of process.env you will now access config.public.apiBase
console.log(config.public.apiBase)
</script>
export default defineEventhandler((event) => {
const config = useRuntimeConfig(event)
// In server, you can now access config.apiSecret, in addition to config.public
console.log(config.apiSecret)
console.log(config.public.apiBase)
})
# Runtime config values are automatically replaced by matching environment variables at runtime
