Runtime Config

When using runtimeConfig option, nitro must have been configured.

Update Runtime Config

Nuxt 3 approaches runtime config differently than Nuxt 2, using a new combined runtimeConfig option.

First, you'll need to combine your publicRuntimeConfig and privateRuntimeConfig properties into a new one called runtimeConfig, with the public config within a key called public.

// nuxt.config.js- privateRuntimeConfig: {-   apiKey: process.env.NUXT_API_KEY || 'super-secret-key'- },- publicRuntimeConfig: {-   websiteURL: 'https://public-data.com'- }+ runtimeConfig: {+   apiKey: process.env.NUXT_API_KEY || 'super-secret-key',+   public: {+     websiteURL: 'https://public-data.com'+   }+ }

This also means that when you need to access public runtime config, it's behind a property called public. If you use public runtime config, you'll need to update your code.

// MyWidget.vue- <div>Website: {{ $config.websiteURL }}</div>+ <div>Website: {{ $config.public.websiteURL }}</div>
