NPM script to compile LESS files because the Visual Studio "Web Compiler" extension doesn't work anymore.

compile-less.js

import fs from 'fs';
import { exec } from 'child_process';

const compilationConfig = JSON.parse(fs.readFileSync('compilerconfig.json', 'utf8'));

compilationConfig
  .filter(fileConfig => fileConfig.inputFile.endsWith('.less'))
  .map(({outputFile, inputFile, minify}) => {
    try {
      console.log("LESS\tInput:\t" + inputFile);
      exec(`lessc "${inputFile}" "${outputFile}"`);
      console.log("\tOutput:\t" + outputFile);

      if (minify) {
        const outputMinFile = outputFile.replace('.css', '.min.css');
        exec(`lessc --compress "${inputFile}" "${outputMinFile}"`);
        console.log("\tOutput:\t" + outputMinFile);
      }
    } catch (e) {
      console.log("LESS processing failed:\n" + e.message);
    }
  });
