Node.js如何优雅的封装一个实用函数的npm包的方法

import chalk from "chalk";

function noop(msg: string): string {
  return msg
}

function log(fn: Function): (msg: string) => void {
  return (msg: string): void => {
    console.log(fn(msg));
  };
}

export default {
  success: log(chalk.green),
  error: log(chalk.red),
  warn: log(chalk.yellow),
  info: log(chalk.cyan),
  log: log(noop)
};

import log from './log'
log.success("hello green message!")
log.error("hello red message!")
log.warn("hello yellow message!")
log.info("hello cyan message!")
log.log("hello normal message!")

Object.defineProperty(module.export, 'log', {
  configurable: false,
  enumerable: true,
  get: () => require('./log')
});
