typescript - ts-node-dev 不应用自动重新加载的更改

Question

我已经在 Typescript 中使用 FeathersJS 构建了一个应用程序，但是尽管 typescript 的 nodemon (ts-node-dev) 说当 typescript 文件更改时服务器已重新启动，但更改并未应用。
我总是需要终止应用程序并重新开始以查看更改。

这是日志:

[INFO] 15:43:51 Restarting: C:\api\src\models\favorites.model.ts has been modified
Using ts-node version 7.0.1, typescript version 3.9.3
info: Feathers application started on http://localhost:3030

这是dev package.json 上的脚本:
ts-node-dev --no-notify src/
这是 tsconfig.json:

{
  "compilerOptions": {
    "target": "es2018",
    "module": "commonjs",
    "outDir": "./lib",
    "rootDir": "./src",
    "strict": true,
    "esModuleInterop": true
  },
  "exclude": [
    "test"
  ]
}

Answer 1

您需要告诉编译器注意更改。添加以下脚本或调整您的 compile带有监视标志的脚本:

"watch-ts": "tsc -w"

或者

"compile": "shx rm -rf lib/ && tsc -w"

我仔细查看了你的脚本，在我看来你应该从编译的文件(我猜它们在 lib 文件夹中)启动你的服务器。如果这是真的，那么您运行服务器的脚本应该是例如:

"dev": "ts-node-dev --no-notify lib/server.js"

您需要在两个单独的终端选项卡中运行:

npm run compile

和

npm run dev
