With Vue, how would I load different CSS files depending on some logic / data?












2















I'm trying to enable different theming options for my app that users can choose from.



I know that I could switch out a class on the <body> tag, but that would make the CSS far messier than just using two different .scss files with different variable values.



Any ideas?

          I can't think of an elegant way to do this. If you're using single file components (SFCs) you can make use of CSS modules. From the vue-loader documentation ..




          You can have more than one <style> tags in a single *.vue
          component. To avoid injected styles to overwrite each other, you can
          customize the name of the injected computed property by giving the
          module attribute a value




          <style module="a">
          /* identifiers injected as a */
          </style>

          <style module="b">
          /* identifiers injected as b */
          </style>


          So you might have a style tag for your common styling, and other style tags for theme specific styling. You can then decide which module/style-tag a class is picked from with a computed property that uses your logic to return the module's name.

          const styleEl = document.createElement("style");
          styleEl.innerHTML = "@import 'alternate.stylesheet.css'";
          document.head.appendChild(this.styleEl);


          (Obviously, you'd load the normal stylesheet by default, and the alternate stylesheet would need to completely override any rules in the normal stylesheet that were not desired.)

            const styleEl = document.createElement("style");
