Import layer with supabase module

Hello, so i have a layer that takes care of the auth in the application Im using supabase module for all the auth and it works well on the layer However, when i try to expand the origin app i got this error on the console

nuxtLayers/authentication/node_modules/@supabase/postgrest-js/dist/cjs/index.js?v=393341da' does not provide an export named 'default'

nuxtLayers/authentication/node_modules/@supabase/postgrest-js/dist/cjs/index.js?v=393341da' does not provide an export named 'default'

I understand only superficially the error - there is no default export name in the file at the node module. However 1) i dont know what is trying to use this 'default' value 2) im not aware what this default value contains 3) since this error doesnt appear on the origin layer idk what could cause it. The app doesnt crashes, the routes are protected so i assume the layer was imported properly. However, the menu on the main app is broken, its no longer possible to navigate between pages in the app with the menu if I import the layer. Not sure where to start to solve this problem

Hi @IsaacR943. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- This issue seems to be related to the ESM (ECMAScript Modules) compatibility of the Supabase module when used in a Nuxt layer. Let's break down the problem and potential solutions: 1. The error you're seeing suggests that there's an attempt to import a default export from a CommonJS module that doesn't have one. This is a common issue when mixing ESM and CommonJS modules. 2. The fact that it works in the layer but not in the main app could be due to differences in how the modules are being imported or bundled. Here are some steps you can try to resolve this issue: 1. Update Supabase and related packages: Make sure you're using the latest version of the Supabase module and related packages. Sometimes, these issues are resolved in newer versions. 2. Check module compatibility: Ensure that the Supabase module you're using is compatible with the version of Nuxt you're running. You can check the Supabase Nuxt module documentation (https://supabase.nuxtjs.org/) for compatibility information. 3. Adjust the import: Try changing how you import the Supabase client in your main app. Instead of using a default import, use a named import. For example:

   import { createClient } from '@supabase/supabase-js'

   import { createClient } from '@supabase/supabase-js'

4. Transpile the problematic module: You can try adding the Supabase module to the build.transpile array in your nuxt.config.ts file. This tells Nuxt to transpile the module, which might resolve ESM-related issues:

   export default defineNuxtConfig({
     build: {
       transpile: ['@supabase/supabase-js']
     }
   })

   export default defineNuxtConfig({
     build: {
       transpile: ['@supabase/supabase-js']
     }
   })

Source: Nuxt documentation on transpiling libraries (https://nuxt.com/docs/guide/concepts/esm#transpiling-libraries) 5. Check for conflicting versions: Ensure that you don't have conflicting versions of Supabase-related packages in your main app and the layer. They should ideally be using the same versions. 6. Investigate the layer setup: Review how the Supabase module is set up in your layer. Make sure it's properly configured and that the configuration is being correctly applied when the layer is imported into the main app. If these steps don't resolve the issue, you might need to dig deeper into how the Supabase module is being used in both your layer and main app. You could try creating a minimal reproduction of the issue and seeking help from the Nuxt or Supabase communities. Remember, when working with layers and modules, it's important to ensure that all parts of your application are compatible with each other and with the Nuxt version you're using. Sometimes, issues like this can be complex and might require careful debugging to resolve. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

1. Packages are up to date 2. Module is compatible for w the nuxt version i use 3. Imposible to know where to adjust the import since the creteClient from supabase-js is not use on any of my files but rather somewhere in node_modules 4. transpile the library doesnt work 5. No way to know which versions of supabase would be conflicting. 6. Since no error is prompt on origin layer the configuration is done correctly - its a problem of the main app
