【中文标题】使用打字稿时nodemon不刷新【英文标题】:nodemon not refreshing when using typescript 【发布时间】:2018-08-26 13:01:23 【问题描述】:我正在使用 NodeJs、express、typescript 和 nodemon 开发一个应用程序。
但是当我更改了ts文件中的一些代码时,页面没有刷新。
如何在js中编译ts文件并用nodemon(或其他工具)刷新浏览器?

所以知道,每当我进行更改时,我都需要停止服务器并再次运行 npm start
【问题讨论】:
替代方法是使用 ts-node How to watch and reload ts-node when typescript file changes的可能重复 【参考方案1】:问题在于您的启动脚本正在观看dist/index.js
。此文件夹仅在代码重新编译为纯 javascript 时才会更改。因此,您将需要查看 TypeScript 文件。最棒的是您可以更改 nodemon 的默认行为。您还需要将ts-node
添加到您的package.json
。
尝试将脚本设置为以下内容:
nodemon --watch 'src/**/*.ts' --exec 'ts-node' src/index.ts
然后,您还需要使用以下内容设置nodemon.json
文件:
"watch": ["src"],
"ext": "ts",
"exec": "ts-node ./src/index.ts"
