+title: Runtime Config
+description: 'Nuxt provides a runtime config API to expose configuration and secrets within your application.'

+
+::warning
+When using `runtimeConfig` option, [nitro](/docs/4.x/bridge/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`.
+
+```diff
+// 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.
+
+```diff
+// MyWidget.vue
+- <div>Website: {{ $config.websiteURL }}</div>
++ <div>Website: {{ $config.public.websiteURL }}</div>
+```
