Parse html style string for a react component

parseHtmlStyles.js

/**
 * @function parseStyles
 * Parses a string of inline styles into a javascript object with casing for react
 *
 * @param {string} styles
 * @returns {Object}
 */
const parseStyles = styles => styles
    .split(';')
    .filter(style => style.split(':')[0] && style.split(':')[1])
    .map(style => [
        style.split(':')[0].trim().replace(/-./g, c => c.substr(1).toUpperCase()),
        style.split(':')[1].trim()
    ])
    .reduce((styleObj, style) => ({
        ...styleObj,
        [style[0]]: style[1],
    }), {});

👍 this is helpful, thank you

In https://reactjs.org/docs/dom-elements.html#style written:
...Vendor prefixes other than ms should begin with a capital letter. ...
So:
style.split(':')[0].trim().replace(/-./g, c => c.substr(1).toUpperCase())
must be replaced with:
style.split(':')[0].trim().replace(/^-ms-/, 'ms-').replace(/-./g, c => c.substr(1).toUpperCase())

This code will significantly improve the performance :

const convertStylesStringToObject = stringStyles => typeof stringStyles === 'string' ? stringStyles
    .split(';')
    .reduce((acc, style) => {
      const colonPosition = style.indexOf(':')

      if (colonPosition === -1) {
        return acc
      }

      const
        camelCaseProperty = style
          .substr(0, colonPosition)
          .trim()
          .replace(/^-ms-/, 'ms-')
          .replace(/-./g, c => c.substr(1).toUpperCase()),
        value = style.substr(colonPosition + 1).trim()
      
      return value ? {...acc, [camelCaseProperty]: value} : acc
    }, {}) : {}
