Can't extend component

Askelia

Hi !
I'm new to flarum and I'd like to publish a private forum.
Since I didn't find a way to moderate signups I decided to develop an extension that adds a password on the registration form. It's probably not the most secure, unless I add a fail2ban-like code but it's enough for my needs.
So I read the documentation and tried to extend the SignUpModal component to add a field for password.

Unfortunately just with this simple code I get an error :Cannot read properties of undefined (reading 'prototype')

Since I almost copied/pasted the documentation I don't understand where I'm wrong. Can you help me ?

Regards,
Emmanuel

Askelia hi!
that occur because you have a wrong import....

wrong:
import SignUpModal from 'flarum/forum/components/SignUpModal.js';

correct:
import SignUpModal from 'flarum/forum/components/SignUpModal'

Just found I tried to import from SignUpModal.js instead of SignUpModal.
Js is not my primary language 😅

If you haven't tried it yet, this extension already does something extremely similar to what you're describing https://discuss.flarum.org/d/17845-friendsofflarum-doorman

Yes thanks I found it while looking for code examples on github and finally installed it.
At least I learnt the basics of flarum extensions...
