Node 8 and npm@5 can work with custom plugins, but you should be using npm@5.3 minimum and npm link.

Let's say you have a directory called web with the nodebb directory within it. Clone your custom plugin repositories into web (so there's, for instance web/nodebb-plugin-customized-by-you), and then run npm link inside the plugin repository directory, and then npm link nodeb-plugin-customized-by-you in the nodebb directory.

@teh_g the reason it happens with node 8 is that npm@5 comes with node 8. This issue is caused by npm@5

@julian you may want to take this to stack overflow. This is a forum for NodeBB, the node based forum software, not a forum for node.js

I'm thinking that you didn't remove the existing define call inside the file. At the end of the file is

"function"==typeof define&&define.amd?define([],C)

You need to change that to

"function"==typeof define&&define.amd?define('iFrameResizer', [],C)

Instead of doing the wrapper thing you said you're doing.

You have to do this for the last one:

<script type="text/javascript">
  require(['iFrameResize'], function (iFrameResize) {
    iFrameResize({
        log: true
    });
  });
</script>

npm install npm@4 -g should also fix this issue

It's due to how npm@5 works.

iOS or Android?

I'm currently learning mongodb, express and node for that project. Should I also use a front end framework, and if yes which one is most suitable for my project (angular, react or vue)?

It depends on how much interactivity your site will have, and how complex you think it could be.

For the forum part I'd like to use nodebb. When a user sign in the site, will he be able to use the forum without having to sign in the later separately ? Also, is it possible to display specific posts in the site (from the forum) ?

This is possible to set up, yes.

@frgilb listview widget? Sounds interesting, like an upcoming events kind of thing?

Anyways yes I saw your investigation, looks right to me, thanks.
