问题
Taking the mat-slide-toggle as an example, locally I see the HTML tag looks like this:
<div
class="mat-slide-toggle-ripple mat-ripple"
mat-ripple=""
ng-reflect-centered="true"
ng-reflect-radius="20"
ng-reflect-animation="[object Object]"
ng-reflect-disabled="false"
ng-reflect-trigger="[object HTMLLabelElement]">
<div class="mat-ripple-element mat-slide-toggle-persistent-ripple"></div>
</div>
However in production, it's missing the Angular attributes:
<div class="mat-slide-toggle-ripple mat-ripple" mat-ripple="">
<div class="mat-ripple-element mat-slide-toggle-persistent-ripple"></div>
</div>
It looks like this in production:
It looks right locally:
I face the same issue with all the other form elements like input. They are missing the ng* attributes on the HTML tag in production.
https://material.angular.io/guide/getting-started:
I have import 'hammerjs'; in main.ts, imported BrowserAnimationsModule in app.module, and ran both npm install --save @angular/material @angular/cdk @angular/animations and npm install --save hammerjs locally. The package.json file is pushed into Git, which production pulls down.
Does anyone know what I'm missing or where to investigate? Maybe I installed some package globally on my desktop and didn't include it in the package.json?
Update
I found that my production build seems to be missing the pre-built 'indigo-pink.css` file.
My styles.scss looks like this:
/* You can add global styles to this file, and also import other style files */
@import "src/assets/fonts/fonts.scss";
@import "src/assets/old_css/some-css.min";
@import "src/assets/old_scss/style";
@import "./src/assets/old_scss/color.scss";
@import "./src/assets/old_scss/variable.scss";
@import "~@ng-select/ng-select/themes/material.theme.css";
@import '~@angular/material/prebuilt-themes/indigo-pink.css';
@import "./src/assets/scss/am.scss";
I realized the ng-reflect attributes are debug attributes. But I haven't been able to figure out why the pre-built theme isn't being built into the production minimized CSS file.

I found the solution in this blog post.
I did a combination of both these things:
You can directly include the pre-built angular-material-theme in the styles.css file.
@import '@angular/material/prebuilt-themes/deeppurple-amber.css';
Note the lack of "~" in front of "@angular".
Update the following in angular.json file.
"styles": [ { "input": "node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css" }, "src/styles.css" ] ```
I had originally tried this but it didn't work:
"styles": [
"node_modules/@angular/material/prebuilt-themes/deeppurple-amber.css",
"src/styles.css"
]
I'm not sure if both are required. I've noticed blog posts and stackoverflow questions regarding removing the "~" from the import, but I haven't come across "styles": [ { "input": "node_modules/..." } ] before. I didn't find this information from the Angular Material docs.

I had a similar issue. Ripples would not work and tooltips were weirdly styled and would not appear at the right place. It seemed like I was missing all the classes starting with "cdk-".
Adding the following import worked, as @gruuuvy mentioned.
@import '@angular/material/prebuilt-themes/deeppurple-amber.css';
It seemed weird to me that I had to import a prebuilt-theme in order for these things to work. I found out, reading the documentation, that I was missing an include which contains all of the basic angular material classes.
// Include the common styles for Angular Material. We include this here so that you only
// have to load a single css file for Angular Material in your app.
// Be sure that you only ever include this mixin once!
@include mat-core();
