How to Import a utility function from Nuxt3 into a Netlify Edge Function

When developing applications with Nuxt3, a common task you might encounter is the need to import utility functions into your serverless functions, particularly when using platforms like Netlify. This guide will guide you through the process of importing a utility function from your utils directory into a Netlify Edge Function.

The Problem

[[See Video to Reveal this Text or Code Snippet]]

Initially, when you attempt to use this function in your edge function, you encounter an error stating that the sum function is not defined. This is because edge functions in Netlify do not automatically recognize your utility functions like your main application does due to differences in how module resolution is handled.

The Solution

To successfully import your utility function into a Netlify Edge Function, follow one of the methods outlined below:

1. Direct Import

You can directly import the utility function by including the correct path relative to your edge function file. Here’s how it should look:
