Angular version: 14.2.7

I added a unique CSS library to my Angular project that is not publicly available. After adding it to app.module.ts:

 import { SapphireButtonModule } from '@sapphire-angular/core';

 imports: [
    SapphireButtonModule,
 ],

Upon saving the file, I encountered this issue:

While there are similar questions out there, none provided clear answers that were helpful for me. How can I resolve this?

Answer №1

Not sure if my answer will be helpful to you, but I believe it contains some key concepts related to build systems.

Every frontend library or framework utilizes a build system to compile projects. For instance, Angular uses webpack for this purpose. In all of my projects, whether Angular or React based, I always create a customized webpack configuration. This is because the default configurations provided are quite basic.

In your case, it seems that the current Angular setup does not support the @ symbol in CSS. Personally, I recommend using css-loader along with MiniCssExtract, and for SCSS files, incorporating scss-loader as well. Here's a snippet of code:

 {
   test: /\.css$/,
   use: [MiniCssExtractPlugin.loader, "css-loader"],
 },
 {
   test: /\.s[ac]ss$/i,
   use: [
         MiniCssExtractPlugin.loader,
         "css-loader",
         "sass-loader",
       ],
 }

I suggest exploring how to create a custom webpack configuration. It can introduce you to many new concepts. For instance, by implementing a custom webpack setup, you can optimize performance by compressing output files to reduce their size.
