Dynamically translates a SASS/SCSS colour file to a JS object

const colors = require("colors");
const fs = require("fs");

const readColours = (file) => {
  if (!fs.existsSync(file)) {
    throw `ERROR: SASS/SCSS file "${file}" doesn't exist`;
  }

  return fs.readFileSync(file).toString();
};

const writeColours = (colours, file, silent) => {
  const result =
    `// Auto-generated via CrossColour\n` +
    `const colours = ${JSON.stringify(
      colours,
      null,
      2
    )};\n\nexport default colours;`;

  const exists = fs.existsSync(file);
  const same = exists && result === fs.readFileSync(file).toString();

  if (!exists || !same) {
    fs.writeFileSync(file, result);

    if (!silent) {
      console.log(colors.green("Colour data successfully emitted"));
    }
  }
};
