Having trouble running a basic nestjs application in Webstorm? You may encounter an error stating: "The experimental support for decorators is a functionality that might undergo changes in upcoming releases."

After following a tutorial, I used the command nest new my-nestjs-01 to create a default nestjs project. I then configured Webstorm to run typescript files by setting up some options.

Now, when I open a .ts file in the editor and click at the top, the current opened file gets executed. However, when I try to execute main.ts, I encounter an error:

 Experimental support for decorators is a feature that is subject to change in a future release. Set the 'experimentalDecorators' option in your 'tsconfig' or 'jsconfig' to remove this warning.

I tried to add additional options to tsconfig.json to resolve the issue but it didn't work out. Here's a snippet of the code:

tsconfig.json:

{
  // Compiler options here
}

main.ts:

import { NestFactory } from '@nestjs/core';
// More code here...

app.module.ts:

// Code snippet for AppModule here

If anyone can provide guidance on how to fix this issue, I would greatly appreciate it.

EDIT:

I tried the suggested solution mentioned in an answer on stackoverflow but unfortunately, it did not solve my problem.

Answer №1

While setting up my WebStorm with NestJs RUN CONFIGURATION, I encountered an issue where I was not pointing to the correct JavaScript file (it should point to the main.js file). In a default installation of NestJs, this main.js file can be found in the ~/dist folder; Here is a screenshot demonstrating a correctly configured setup: https://i.sstatic.net/3QwPn.png
