ES Module issue with Nuxt 3

[towerhufham]

In the current Nuxt 3 version, v3.0.0-rc.6, trying to import @animxyz/vue3 causes a warning and the server to stall out.

Steps I took:
init a new Nuxt 3 project with nuxi.
run yarn add @animxyz/vue3.
Then I added this code to the /plugins folder:

import VueAnimXyz from '@animxyz/vue3'
import '@animxyz/core'

export default defineNuxtPlugin((nuxtApp) => {
    nuxtApp.vueApp.use(VueAnimXyz);
})

When the server is launched, the message in the console reads:

(node:7804) Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension.
(Use `node --trace-warnings ...` to show where the warning was created)

It then stalls out for a while. After a few minutes, the console shows this and crashes:

<--- Last few GCs --->

I'm also facing the same issue. Tried adding a module to build transpile in nuxt config but that didn't work:

  build: {
    transpile: ['@animxyz/vue3'],
  },

[codeflorist]

This should work:

build: {
    transpile: ['@animxyz/core', '@animxyz/vue3', 'clsx'],
},

[towerhufham]

This should work:

build: {
    transpile: ['@animxyz/core', '@animxyz/vue3', 'clsx'],
},

This worked perfectly, thank you! Probably something worth adding to the docs.

[codeflorist]

it's actually an issue with ESM compatibility and should be fixed by the animxyz-authors as described here: https://v3.nuxtjs.org/guide/going-further/esm#library-author-guide

[towerhufham]

In that case, reopening for visibility

[oeguenes]

This should work:

build: {
    transpile: ['@animxyz/core', '@animxyz/vue3', 'clsx'],
},

This worked perfectly, thank you! Probably something worth adding to the docs.

This didn't work for me at all. Can you please explain how you got this running with nuxt3? It seems like it's just using the css but attributes like "appear" or "appear-visible" don't have any effect.

I'm using nuxt 3.7.4 btw and animxyz/vue3 0.6.7
