Nestjs/swagger open browser automatically like in REACT

Question

I'd like my Nestjs/swagger application to start up as soon as bootstrap is finished

Initially I thought of using the callback of

async function bootstrap(): Promise<void> {
    console.clear();
    console.log("Starting and validating");

    const app = await NestFactory.create<NestExpressApplication>(AppModule, {
        cors: true,
    });

    await app.listen(PORT, () => someOpenBrowserFuncion("/docs")`));
}
bootstrap();

But I didn't find anything like that, so I thought

When we start a REACT app, as soon as it is compiled, it opens the default browser automatically. and This option can be disabled with the following command:

"scripts": {
  "start": "env BROWSER=none react-scripts start",
  "build": "react-scripts build",
  "test": "react-scripts test",
  "eject": "react-scripts eject"
},

Is there a similar function in the Nestjs/swagger framework?

"scripts": {
  "build": "nest build",
  "dev": "nest start --watch",
  "start": "env BROWSER=true nest start",
  "production": "node dist/main",

},

Or some configuration to launch browser on certain endpoint?

You can install a npm package cross-env : npm install cross-env

And update this command in the package.json file under 'scripts';

"start": "cross-env BROWSER='chrome' nest start"

BROWSER is an environment variable, and you can use the cross-env package to properly handle it.

Linux:
 BROWSER='google-chrome-stable'
Windows:
 BROWSER='chrome'
OS X:
 BROWSER='google chrome'

If these don't work, you can update the script:

Windows:
"start": "start http://localhost:3000 & nest start"
Mac:
"start": "open http://localhost:3000 && nest start"
Linux:
"start": "xdg-open http://localhost:3000 && nest start"

You can change your own port number.
