Visual Studio Code provides experimental support for decorators, a feature that may undergo further changes in the future

Recently, I encountered the warning message "[ts] Experimental support for decorators is a feature that is subject to change in a future release. Set the 'experimentalDecorators' option to remove this warning."

As a newcomer to Angular, I am unsure about how to address this issue.

Here is the content of my tsconfig.json file :

    {  
    "compilerOptions":{  
      "allowSyntheticDefaultImports":true,
      "declaration":false,
      "emitDecoratorMetadata":true,
      "experimentalDecorators":true,
      "lib":[  
         "dom",
         "es2015"
      ],
      "module":"es2015",
      "moduleResolution":"node",
      "sourceMap":true,
      "target":"es5"
    },
    "include":[  
       "src/**/*.ts"
    ],
    "exclude":[  
       "node_modules"
    ],
    "compileOnSave":false,
    "atom":{  
       "rewriteTsconfig":false
     } 
   }

Answer №1

When using the editor in the src folder, make sure to open it on the true root of your project where the tsconfig is located for vscode's language service to locate it correctly.

Answer №2

To enable experimental decorators in Visual Studio Code, you simply need to add the following line to your settings:

"javascript.implicitProjectConfig.experimentalDecorators": true

Save the changes and enjoy using experimental decorators!

Answer №3

Make sure to relocate your tsconfig.json to the root directory and then restart your IDE. This should resolve the issue.

Answer №4

Meirion Hughes gave an accurate answer, and I would like to mention that this method is also effective in JavaScript environments.

If you're working with JavaScript, simply name the configuration file jsconfig.json.
