Answer a question

I'm attempting to create an apollo client plugin for a Nuxt 3 application. It's currently throwing an error regarding a package called ts-invariant:

file:///Users/[my name]/Repositories/[project]/node_modules/@apollo/client/utilities/globals/fix-graphql.js:1
import { remove } from "ts-invariant/process/index.js";
         ^^^^^^
SyntaxError: Named export 'remove' not found. The requested module 'ts-invariant/process/index.js' is a CommonJS module, which may not support all module.exports as named exports.
CommonJS modules can always be imported via the default export, for example using:

import pkg from 'ts-invariant/process/index.js';
const { remove } = pkg;

I feel like I know enough about this error to know it has something to do with how Nuxt 3 deals with ESM, but I can't be for certain.

Here's the nuxt plugin:
plugins/apollo-client.js

import { defineNuxtPlugin } from "#app"
import { ApolloClient, InMemoryCache } from "@apollo/client/core"
import { DefaultApolloClient } from "@vue/apollo-composable"

export default defineNuxtPlugin((nuxtApp) => {
  const config = useRuntimeConfig()
  const apolloClient = new ApolloClient({
    uri: config.PUBLIC_API_ENDPOINT,
    cache: new InMemoryCache(),
  })
  nuxtApp.vueApp.provide(DefaultApolloClient, apolloClient)
})

In a normal scenario, I might use the nuxt-apollo community module, but it is currently afk regarding a nuxt 3 port, so a plugin it is.

Here's some documentation I relied on for my plugin:
https://v4.apollo.vuejs.org/guide-composable/setup.html#vue-3
https://v3.nuxtjs.org/docs/directory-structure/plugins

Solved by including @apollo/client and ts-invariant/process into the nuxt build transpile like so:

  // nuxt.config.js
  // ...
  build: {
    postcss: {
      postcssOptions: require('./postcss.config.js')
    },
    transpile: [
      '@apollo/client',
      'ts-invariant/process',
    ],
  },
  // ...
