How to use the pug.renderFile function in pug

function makeHtml({htmlSettings, scripts, links, styles}, config) {
  /**

   */
  console.log(`  Making ${htmlSettings.dest}`)
  Object.assign(htmlSettings, {scripts, links, styles}) // add links + scripts
  const sections = Array.from(genSections(htmlSettings, config))
  const locals = Object.assign(htmlSettings, {sections})
  const html = pug.renderFile('src/index.pug', locals)
  fs.writeFileSync(htmlSettings.dest, html)
}

    if (!fs.existsSync(src)) {
        console.log('skipped:', target);
        return;
    }

    const html = pug.renderFile(src, object);
