Hi @kb. 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 information provided in the knowledge sources, it appears that you're encountering a linting issue related to using await in the setup function. This is a common concern when working with Nuxt and Vue 3. Let me provide some context and suggestions: 1. The linting rule you're encountering is likely related to the Vue 3 rule vue/no-expose-after-await (https://eslint.vuejs.org/rules/no-expose-after-await), which warns against using defineExpose after an await statement in the setup function. 2. This rule exists because using await in the setup function can lead to unexpected behavior, especially when combined with defineExpose. 3. Nuxt has been working on addressing this issue. As mentioned in a GitHub issue comment, there was a fix attempt that was later reverted GitHub PR #24784 (https://github.com/nuxt/nuxt/pull/24784). Given this context, here are some suggestions: 1. If you're using useAsyncData or useFetch, you can consider using the lazy option to defer the asynchronous operation:

const { data, status, error } = useAsyncData(
  'someKey',
  () => someAsyncOperation(),
  { lazy: true }
)

const { data, status, error } = useAsyncData(
  'someKey',
  () => someAsyncOperation(),
  { lazy: true }
)

This approach is documented in the Nuxt Data Fetching guide (https://nuxt.com/docs/getting-started/data-fetching#lazy). 2. If you need to use await in your setup function and it's causing linting issues, you might consider disabling the specific linting rule for that file or block of code. However, this should be done cautiously and only if you understand the implications. 3. Another approach could be to move the asynchronous operation into a separate function or composable that you call from within your component, rather than directly in the setup function. 4. If you're using the @nuxt/eslint module, you can customize the ESLint configuration. You might want to check if there are any Nuxt-specific rules that could help with this situation. You can find more information about this in the Nuxt ESLint documentation (https://eslint.nuxt.com/packages/module#custom-config-presets). Remember, the best approach depends on your specific use case and the structure of your application. If possible, try to adhere to the linting rules as they often help prevent potential issues. If you decide to disable the rule, make sure you understand the potential consequences. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
