Replace ModularLoad with Barba

[lucasvallenet]

Remove modularload and use barba instead.
It is located in the same module Load.js and uses the data-module-load namespace.

I also added a config.js file in the script root to have global vars (env, classnames, etc...) and updated the utils/environment.js with dom elements.

We won't merge the barba branch yet, but I think we could make use of the config.js already. Any idea on how to implement that, should I create a new pull request with this file only ?

Yes, create a new pull request with only the changes to config.js (dom.js and environment.js, too?). Then this pull request can be rebased according to that and merged afterwards when ready.

[lucasvallenet]

We can maybe add these changed to PR#120 that is likely to be merged soon ?

Outcome from meeting on 2022-10-05
Status: On hold until further notice.
We like the idea, but we need to do more tests before deciding if we use Barba.js. It depends on our current usage of modular load.
