ES6 module to recursively convert snake case keys in an object to camel case using lodash.

snakeToCamelCase.js

'use strict';

import 'lodash';

export default function (object) {
  let camelCaseObject = _.cloneDeep(object);

  // Convert keys to camel case
  camelCaseObject = _.mapKeys(camelCaseObject, (value, key) => {
    return key.replace(/(_\w)/, match => match[1].toUpperCase());
  });

  // Recursively apply throughout object
  return _.mapValues(
    camelCaseObject,
    value => {
      if (_.isPlainObject(value)) {
        return keysToCamelCase(value);
      } else if (_.isArray(value)) {
        return _.map(value, keysToCamelCase);
      } else {
        return value;
      }
    }
  );
}

Nice! Use global replace for multiple snake_case words (e.g. my_bad_key).
