Rails Webpacker

[redhoodie]

(This more a n00b question than an issue)
How do I use this with webpacker?

What is the equivalent of:
//= require materialize

Could you please update the Usage section in Readme.md?

@redhoodie Was wondering the same thing. I think this Medium article does a good job of explaining it:

Is it me or since this is an engine this is not compatible with Webpacker?
So new default rails app can't use this gem.

hello :)
i think i found a way to use the javascript of this gem in a default rails 6 app.

1. enable webpacker to use .erb via rails webpacker:install:erb. this will add the line environment.loaders.prepend('erb', erb) to config/webpack/environment.js
2. rename app/assets/javascript/packs/application.js -> app/assets/javascript/packs/application.js.erb
3. import materialize.js from the materialize gem into application.js.erb via ruby tags, so the file will look like this

(from a brand new rails app)

// This file is automatically compiled by Webpack, along with any other files
// present in this directory. You're encouraged to place your actual application logic in
// a relevant structure within app/javascript and only use these pack files to reference
// that code so it'll be compiled.

import Rails from "@rails/ujs"
import Turbolinks from "turbolinks"
import * as ActiveStorage from "@rails/activestorage"
import "channels"

Rails.start()
Turbolinks.start()
ActiveStorage.start()

// add this line at the bottom! be sure to place any materialize.js api calls after this is loaded
<%= File.read(File.join(Gem.loaded_specs['materialize-sass'].full_gem_path, 'assets', 'javascripts', 'materialize.js')) %>

Now we can use the materialize javascript api like in the documentation!

document.addEventListener('DOMContentLoaded', function() {
    var elems = document.querySelectorAll('.sidenav');
    var instances = M.Sidenav.init(elems, {}); // M is now defined :)
});
