使用angular-cli定义全局sass变量

Question

In my project, I need to inject a global variable to be used across the app, from an environment file, into SCSS files.

Following an advice such as this , isn't possible for me since the app contains ~50 different possible configs, so maintaining so many projects in angular.json is just not feasible.

In our current setup, using webpack, we used the data option for sass-loader to inject what ever variable imported from the environment file. This is currently impossible with angular-cli - making the migration impossible.

How can we achieve this?

I ended up succesfuly using ngx-build-plus , followed this article, and used this webpack.extra.js :

const webpack = require('webpack');
const configs = require('./src/configs');

module.exports = {
  plugins: [new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/)],
  resolve: {
    modules: ["node_modules"],
  },
  module: {
    rules: [
      {
        test: /\.scss$/,
        use: [
          {
            loader: 'sass-loader',
            options: {
              sourceMap: true,
              includePaths: ["src/ng1/assets/sass"],
              data: `
                    $templateTheme: ${configs.templateTheme};
                  `,
            },
          },
        ],
      },
    ],
  },
};
