I'm getting "[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."

I'm new to Angular and I don't how to solve it.

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
     } 
   }

Print :

You've opened the editor on the src folder. For vscode's language service to find your tsconfig, you need to open the editor on the true root of the project holding your config.

Opened on root folder:

Opened on src folder:

You can set

"javascript.implicitProjectConfig.experimentalDecorators": true

in your vscode setting.

Move your tsconfig.json inside the root folder and restart the IDE. That should work.

Meirion Hughes answer is correct, I just want to add that this works in JS environments as well.

In that case name the config file jsconfig.json.
