"The Fetch API is an experimental feature. This feature could change at any time" while installing a Nuxt3 app

Question

I try to creat new nuxt app using fallowing command

npx nuxi init my-app

successfully creating new app with Nuxt 3.0 stable inside but i get this annoying response

Nuxi 3.0.0-rc.10                                                                                              15:04:22

 ERROR  (node:35527) ExperimentalWarning: The Fetch API is an experimental feature. This feature could change at any time
(Use `node --trace-warnings ...` to show where the warning was created)

What confuses me is the version of Nuxi 3.0.0-rc.10 and the Error I belive it comes from node.

node - 18.12.1

npm - 8.19.2

git - 2.38.1

Answer 1

First off, you should be running Nuxt 3.0.0 (stable version), not the RC.

Also, this is a warning hence something that you can omit. Especially because it is tied to Node v18 itself and not Vue/Nuxt. Some details on how to suppress the warning are available here: https://github.com.netlify/cli/issues/4608#issuecomment-1223696635

As for the warning, it is a common thing to have experimental features marked until they are fully stable. Here is the official source for that one.

Answer 2

I helped upgrade the version node v18.12.1 -> v19.4.0

Answer 3

It was enough for me to upgrade to node 18.13.0

You can also try --no-experimental-fetch flag.
