Node.js 从项目中找到所有未定义的变量

Question

我正在用 Node.js
开发后端 API 有时，我无法进行单元测试，并且 data is not defined 发生错误
有了typescript，我们可以用lint系统解决这个问题。
Angular 9项目，编译系统检测到该问题，自动解决该错误。

但是，如何使用 node.js 项目进行配置？

我检查了 esLint 工具，但是，它似乎在使用 ts 文件

Answer 1

eslint 解决了我的问题
此外，我在 git 提交之前使用 git 钩子检查 eslint https://gist.github.com/linhmtran168/2286aeafe747e78f53bf
