Utility for building custom UI components

import { ESLint } from 'eslint';
import chalk from 'chalk';
// import { addDebugLog } from '../../util.js';


export const lintComponent = async (dirToLint) => {
// addDebugLog("lintComponent", `dirToLint: ${dirToLint}`);

  // console.log("in dx-component-builder-sdk: lintComponent - dirToLint: " + dirToLint);
  console.log(chalk.green(` linting ${dirToLint}`));

  // 1. Create an instance.
  const eslint = new ESLint();

  // 2. Lint files.
  const results = await eslint.lintFiles([dirToLint]);

  // 3. Format the results.
  const formatter = await eslint.loadFormatter("stylish");
  const resultText = formatter.format(results);

  // Indicate linting is complete
  console.log(chalk.green(` linting complete...`));

  if (resultText.length > 0 && resultText.indexOf("error") >= 0) {
    throw new Error( "Lint:\n" + resultText );
  }
  else {
    console.log(resultText);
  }
};
