javascript - How to use materialize-css with angular

Question

I have created an angular4 project with angular-cli. I want to materialize-css@next library. So I have installed it using

npm install materialize-css@next --save

so this installed

"materialize-css": "^1.0.0-alpha.2",

Then in the angular-cli.json I have added reference to css and js file

"styles": [
   "styles.css",
   "../node_modules/materialize-css/dist/css/materialize.css"
],
"scripts": [
   "../node_modules/materialize-css/dist/js/materialize.js"
],

Now this is working fine for normal components like button and navigation bar as these components do not need any js.

How can I create dynamic elements like the carousel, collapsible and other components in which there is the requirement for js?

As I have googled there are wrapper libraries like angualr2-materialize

So I have installed this

npm install angular2-materialize --save

And imported the module in my app.module.ts

import { MaterializeModule } from 'angular2-materialize';

and then in imports array of @NgModule

imports: [
  BrowserModule,
  MaterializeModule
],

and when I use the following markup

<a class="waves-effect waves-light btn modal-trigger" (click)="openModal()">Modal</a>

<div id="modal1" class="modal bottom-sheet" materialize="modal" [materializeParams]="[{dismissible: false}]" [materializeActions]="modalActions">
    <div class="modal-content">
        <h4>Modal Header</h4>
        <p>A bunch of text</p>
    </div>
    <div class="modal-footer">
        <a class="waves-effect waves-green btn-flat" (click)="closeModal()">Close</a>
        <a class="modal-action modal-close waves-effect waves-green btn-flat">Agree</a>
    </div>
</div>

It is showing

index.js:4 Uncaught Error: Couldn't find Materialize object on window. It is created by the materialize-css library. Please import materialize-css before importing angular2-materialize.

Am I missing something?

Is there any way to use MaterializeCSS library without using wrappers?

Answer 1

angular2-materialize is based on materialize-css 0.X. As materialize-css 1.X has not dependency on jQuery. Even I did not found any wrapper over this and I don't want to use the wrapper modules. So I have solved this problem by following these steps.

1) JS and CSS Reference in angular-cli.json

"styles": [
   "styles.css",
   "../node_modules/materialize-css/dist/css/materialize.css"
],
"scripts": [
  "../node_modules/hammerjs/hammer.js",
  "../node_modules/materialize-css/dist/js/materialize.js"
]

hammerjs is required for some components to listen sliding events.

2) Import in ts

import * as M from "materialize-css/dist/js/materialize";

3) Get the element Reference

@ViewChild('collapsible') elCollapsible: ElementRef;

4) Wrap the element

ngAfterViewInit() {
    let instanceCollapsible = new M.Collapsible(this.elCollapsible.nativeElement, {});
}

5) Do not forget #collapsible on your <ul #collapsible>

And done.
