getting Nuxt context into a nitro route

Hey guys, I'm trying to create an adapter for our auth provider, logto, and it's proving to be a bit more difficult than I expected. Originally I was accessing our logto context via nuxtApp.ssrContext?.event.context.logtoClient unfortunately this doesn't work client sided, as you might expect, so I decided to create a nitro route for client requests to go through.

import type LogtoClient from "@logto/node";

export default defineEventHandler(async () => {
    const nuxtApp = useNuxtApp();
    const logtoClient = nuxtApp.ssrContext?.event.context.logtoClient as LogtoClient
    ...

import type LogtoClient from "@logto/node";

export default defineEventHandler(async () => {
    const nuxtApp = useNuxtApp();
    const logtoClient = nuxtApp.ssrContext?.event.context.logtoClient as LogtoClient
    ...

Unfortunately, I found out I can't access nuxtApp in nitro routes. Does anyone know how I can get that injected context into a nitro route?

Hi @Zach. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- You're correct that you can't directly access nuxtApp in Nitro routes. However, there are a few approaches you can take to solve this problem: 1. Use useRuntimeConfig: Instead of trying to access the Nuxt context directly, you can use useRuntimeConfig in your Nitro route. This allows you to access runtime configuration, which you can set up to include the necessary information.

   export default defineEventHandler(async (event) => {
     const config = useRuntimeConfig(event);
     // Access your logto configuration from config
     // ...
   });

   export default defineEventHandler(async (event) => {
     const config = useRuntimeConfig(event);
     // Access your logto configuration from config
     // ...
   });

You would need to set up your runtimeConfig in your nuxt.config.ts file to include the necessary Logto information Nitro Configuration (https://nitro.unjs.io/guide/configuration#runtime-configuration). 2. Use a server plugin: You can create a Nitro server plugin to inject the Logto client into the event context, which you can then access in your route handlers. First, create a server plugin:

   // server/plugins/logto.ts
   import LogtoClient from "@logto/node";

   export default defineNitroPlugin((nitroApp) => {
     nitroApp.hooks.hook('request', (event) => {
       event.context.logtoClient = new LogtoClient(/* your config here */);
     });
   });

   // server/plugins/logto.ts
   import LogtoClient from "@logto/node";

   export default defineNitroPlugin((nitroApp) => {
     nitroApp.hooks.hook('request', (event) => {
       event.context.logtoClient = new LogtoClient(/* your config here */);
     });
   });

Then, in your route handler:

   export default defineEventHandler(async (event) => {
     const logtoClient = event.context.logtoClient as LogtoClient;
     // Use logtoClient...
   });

   export default defineEventHandler(async (event) => {
     const logtoClient = event.context.logtoClient as LogtoClient;
     // Use logtoClient...
   });

This approach allows you to have the Logto client available in all your server routes Server Plugins (https://nuxt.com/docs/guide/directory-structure/server#server-plugins). 3. Use useEvent(): If you've enabled the experimental async context feature in Nitro, you can use useEvent() to access the event context:

   export default defineEventHandler(async () => {
     const event = useEvent();
     const logtoClient = event.context.logtoClient as LogtoClient;
     // Use logtoClient...
   });

   export default defineEventHandler(async () => {
     const event = useEvent();
     const logtoClient = event.context.logtoClient as LogtoClient;
     // Use logtoClient...
   });

To enable this feature, you need to set the asyncContext flag in your Nitro configuration Async Context (Experimental) (https://nitro.unjs.io/guide/utils#async-context-experimental). These approaches allow you to access the necessary context or configuration in your Nitro routes without directly relying on nuxtApp. The best choice depends on your specific setup and requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai It doesn't look like I can access useNuxtApp() in a plugin either...

Let me check the knowledge base for you again. One moment! :books: ---------------------- You're right, and I apologize for any confusion. Let me clarify this for you. In Nuxt 3, you actually can access useNuxtApp() in a plugin. Plugins are one of the places where useNuxtApp() is available and commonly used. However, the way you use it in a plugin is slightly different from how you might use it in a component or composable. Here's how you can use useNuxtApp() in a Nuxt plugin:

export default defineNuxtPlugin((nuxtApp) => {
  // You can access nuxtApp directly as an argument
  console.log(nuxtApp)

  // Or you can use useNuxtApp() if needed
  const nuxtAppInstance = useNuxtApp()

  // They should be the same
  console.log(nuxtApp === nuxtAppInstance) // true

  // You can now use nuxtApp or nuxtAppInstance
  // to access the Nuxt app instance and its properties
})

export default defineNuxtPlugin((nuxtApp) => {
  // You can access nuxtApp directly as an argument
  console.log(nuxtApp)

  // Or you can use useNuxtApp() if needed
  const nuxtAppInstance = useNuxtApp()

  // They should be the same
  console.log(nuxtApp === nuxtAppInstance) // true

  // You can now use nuxtApp or nuxtAppInstance
  // to access the Nuxt app instance and its properties
})

This approach is documented in the Nuxt documentation on plugins (https://nuxt.com/docs/guide/directory-structure/plugins#using-composables). The nuxtApp instance is automatically provided as an argument to the plugin function when you use defineNuxtPlugin. This is the recommended way to access the Nuxt app instance in a plugin. If you're experiencing issues accessing useNuxtApp() in a plugin, it could be due to how the plugin is defined or where it's placed in your project structure. Make sure your plugin is in the correct directory (usually plugins/) and is properly exported using defineNuxtPlugin. If you're still having trouble, could you share the specific code of your plugin where you're trying to use useNuxtApp()? That would help in identifying any potential issues. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
