TypeScript CLI：自动化构建和部署脚本

“纵有疾风来，人生不言弃”，这句话送给正在学习文章的朋友们，也希望在阅读本文《TypeScript CLI：自动化构建和部署脚本》后，能够真的帮助到大家。我也会在后续的文章中，陆续更新文章相关的技术文章，有好的建议欢迎大家在评论留言，非常感谢！

>我想跟进我以前的有关打字稿cli的文章。我要继续进行以下操作：我计划实现构建命令以构建vite应用程序和deploy命令，以将应用程序部署到amazon s3和aws cloudfront。

任务分为构建任务和部署任务。由于部署需要一个构建步骤，因此我们使用启用属性来有条件地启用基于cli命令构建或部署的任务。每个任务都执行相应的cli命令并将其输出输出到控制台。 >将此脚本保存为cli.ts，并使用pnpm tsx cli运行：
