How to use the textlint.TextFixEngine function in textlint

module.exports = function lintFiles (input, options) {
  const config = createConfig(options)
  const patterns = input.length === 0 ? ['**/*.md'] : input

  const engine = options.fix
    ? new textlint.TextFixEngine(config)
    : new textlint.TextLintEngine(config)

  return globby(patterns, {gitignore: true})
    .then(paths => engine.executeOnFiles(paths))
    .then(results => {
      if (!options.fix) {
        return results
      }

      const fixer = new TextLintFixer()

      return fixer.write(results).then(() => results)
    })
}

module.exports = function fixFiles (paths, options) {
  const engine = new TextFixEngine(options)

  return engine.executeOnFiles(paths).then(results => {
    const fixer = new TextLintFixer()
    return fixer.write(results).then(() => results)
  })
}

get fixEngine() {
        if (this._textFixEngine) {
            return this._textFixEngine;
        }
        const textFixEngine = new textlint.TextFixEngine({
            configFile: this.configFile,
            rulesBaseDirectory: this.rulesBaseDirectory
        });
        this._textFixEngine = textFixEngine;
        return textFixEngine;
    }
