Logs in the console stuck saying [12:06:59 PM] File change detected. Starting incremental compilation in nestjs

When I start the nest application, then it successfully starts and shows the logs given below.

I've used command npm run dev:start to start the project.

[11:55:17 AM] File change detected. Starting incremental compilation...

[11:55:17 AM] Found 0 errors. Watching for file changes.

Now if I send any request to the end points, it successfully sends the request and data get stored in the database and also returns the data but the problem is code gets recompiled and in console it displays

[12:06:59 PM] File change detected. Starting incremental compilation...

and it doesn't show the log messages. How can I fix this?

As mentioned in NestJs Documentation in Windows operating system for Typescript version 9+ we need to add following after compilerOptions in tsconfig file:

"watchOptions": { "watchFile": "fixedPollingInterval" }

If the above doesn't work, here is how i fixed the issue

This is something related with your OS (Windows 11 in my case) and ts 4.9

Try it out with typescript 4.8 instead, in the package.json include

"devDependencies": {
  ...,
  "typescript": "4.8.3",
  ...
}

later

npm i
npm run start:dev

if the above doesn't work, here is how i fixed the issue

for NestJS

inside the : tsconfig.build.json file

Add "include": ["./src"]

Looks like this

tsconfig.build.json

{
      "extends": "./tsconfig.json",
      "exclude": ["node_modules", "test", "dist", "**/*spec.ts"],
      "include": ["./src"]
    }

Add to your tsconfig.json:

"include": [
    "src"
]
