server/api errors using [[ ]].ts files

Hi all, beginner here, so please be gentle lol From reading the internet, i can use a [[xx]].ts file for urls that might not be present eg /api/[something]/is-here/[[or-is-it]] whenever I try to access the api (using postman) at /api/something/is-here i get a 500 error, and i get the same error when i try to access /api/[something]/is-here/yes my file is [[or-is-it]].ts if i change it to index.ts, accessing /api/something/is-here works perfectly fine, as does if i make a folder for [or-is-it] with an index.ts file in it, but i get whinged at becuase of duplicaed code I'm trying to use the or-is-it for page numbers, the code looks for or-is-it and if not found sets it to 1 any advice would be appreciated thanks

Hi @Dex_Vinyl. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- Based on the knowledge sources provided, I can offer some insights into your issue with server API routes in Nuxt 3. The use of double square brackets [[...]] in Nuxt 3 is typically associated with catch-all routes, which are designed to match multiple levels of nested routes. However, the knowledge sources don't provide specific information about using [[...]] in the context you've described. Instead, for optional parameters in API routes, Nuxt 3 typically uses single square brackets [...]. Here's how you might structure your API route: 1. For a route that can handle both /api/something/is-here and /api/something/is-here/page-number, you could create a file named: server/api/something/is-here/[or-is-it].ts 2. In this file, you can define your event handler to check for the optional parameter:

export default defineEventHandler((event) => {
  const orIsIt = getRouterParam(event, 'or-is-it') || '1'
  // Your logic here, using orIsIt as the page number
  return { page: orIsIt }
})

export default defineEventHandler((event) => {
  const orIsIt = getRouterParam(event, 'or-is-it') || '1'
  // Your logic here, using orIsIt as the page number
  return { page: orIsIt }
})

This approach should allow you to handle both cases without duplicating code. If you're still encountering 500 errors, it might be helpful to check your server logs for more detailed error messages. The 500 error suggests there might be an issue in your route handler code rather than the route definition itself. For more information on Nuxt 3 server routes and API handling, you can refer to the Nuxt 3 documentation on the server directory structure (https://nuxt.com/docs/guide/directory-structure/server). If this doesn't solve your issue, you might want to share more details about your specific implementation, including the content of your route handler file and any error messages you're seeing in the server logs. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

@kapa.ai this suggestions works only when [or-is-it] has a value, if the root of the folder is hit, error message occurs, despite having the || 1 on the const as suggested

Let me check the knowledge base for you again. One moment! :books: ---------------------- I apologize for the confusion in my previous answer. You're right to point out that the suggested approach doesn't fully solve the issue when the root of the folder is accessed. Let's address this problem more accurately based on the Nuxt 3 documentation. For handling optional parameters in Nuxt 3 API routes, we can use a catch-all route with the [...slug].ts naming convention. This approach allows us to handle both the root path and paths with additional segments. Here's how you can implement it: 1. Create a file named [...slug].ts in your server/api/something/is-here/ directory. 2. In this file, use the following code:

export default defineEventHandler((event) => {
  const slug = event.context.params.slug || []
  const pageNumber = slug[0] || '1'
  
  // Your logic here, using pageNumber
  return { page: pageNumber }
})

export default defineEventHandler((event) => {
  const slug = event.context.params.slug || []
  const pageNumber = slug[0] || '1'
  
  // Your logic here, using pageNumber
  return { page: pageNumber }
})

This setup will handle the following scenarios: - /api/something/is-here (slug will be an empty array, pageNumber will be '1') - /api/something/is-here/2 (slug will be ['2'], pageNumber will be '2') - /api/something/is-here/any/other/path (slug will be ['any', 'other', 'path'], pageNumber will be 'any') This approach is based on the information from the Nuxt 3 documentation on catch-all routes (https://nuxt.com/docs/guide/directory-structure/server#catch-all-route), which states: "Catch-all routes are helpful for fallback route handling. For example, creating a file named ~/server/api/foo/[...].ts will register a catch-all route for all requests that do not match any route handler, such as /api/foo/bar/baz." By using [...slug].ts, we ensure that all requests to this endpoint are handled, whether or not additional path segments are present. If you're still encountering issues with this approach, it would be helpful to see the exact error message you're receiving and any relevant server logs. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
