Angular DevExtreme Themes

I am trying to load themes for the DevExtreme widgets for angular. I have followed different approaches:

  1. Set the style in angular.json but it doesn't cause any effect:

    "projects": {
"my-project": {
  "root": "",
  "sourceRoot": "src",
  "projectType": "application",
  "architect": {
    "build": {
      "builder": "@angular-devkit/build-angular:browser",
      "options": {
        "outputPath": "dist",
        "index": "src/index.html",
        "main": "src/main.ts",
        "tsConfig": "src/tsconfig.app.json",
        "polyfills": "src/polyfills.ts",
        "assets": [
          "src/assets",
          "src/favicon.ico",
          "src/manifest.json"
        ],
        "styles": [
          "node_modules/font-awesome/css/font-awesome.min.css",
          "node_modules/material-design-icons/iconfont/material-icons.css",
          "node_modules/@angular/material/prebuilt-themes/indigo-pink.css",
          "node_modules/devextreme/dist/css/dx.common.css",
          "node_modules/devextreme/dist/css/dx.dark.css",
          "src/sass/styles.scss"
        ],

  2. Set it in index.html but also no effect:

    <head>
   ...
  <link rel="dx-theme" data-theme="generic.dark" href="https://cdn3.devexpress.com/jslib/18.2.3/css/dx.dark.css" data-active="true" />
</head>

and set it with DxThemes.current('generic.dark');

  1. Use the locale css files as in (2):

    <head>
   ...
  <link rel="dx-theme" data-theme="generic.dark" href="css/dx.dark.css" data-active="false" />
</head>

But my browser says:

Refused to apply style from 'http://localhost:4200/css/dx.dark.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

So my questions are: How can i use the locale css files? And why aren't the themes applied?

Solution

  • The trick is to build the project with ng build --prod. With ng serve or without production mode it doesn't work...
