0060 JavaScript模块化:CommonJS与ESM之争

from Web技术动态

这些来源主要讨论了JavaScript模块系统的演变,重点比较了CommonJS (CJS) 和ECMAScript Modules (ESM)。它们解释了ESM作为JavaScript官方标准的重要性,它支持浏览器和服务器环境,并提供了异步加载和摇树优化等优点。然而,由于Node.js长期以来默认使用同步的CommonJS,导致现有大量代码库的兼容性问题和迁移挑战。文章还探讨了如何逐步从CommonJS迁移到ESM,包括文件命名约定(如.mjs)、package.json中的"type": "module"设置,以及如何在两种模块系统之间进行互操作。此外,来源也提到了围绕这种转变在开发者社区中引发的痛点和争议。
