VSCode: Is it possible to suppress experimental decorator warnings

Question

In VSCode, I get the error:

"Experimental support for decorators is a feature that is subject to change in a future release. Specify '--experimentalDecorators' to remove this warning."

I can add the --experimentalDecorators flag to my tasks.json file to remove this error on build, but I can't seem to remove it from my intellisense or error list when I load VSCode.

Is there a way to do this?

Answer 1

I was having this same error. I added the following tsconfig.json file to my project root, restarted VSCode and it finally went away:

{
    "compilerOptions": {
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "module": "amd",
        "target": "ES6" 
    }
}

UPDATE:

I've noticed that sometimes VS Code will not suppress this warning until you add a "files" array in your tsconfig.json, even an empty one will work. For me this has worked every single time now, if the message does not disappear, try the following:

{
    "compilerOptions": {
        ... 
    },
    "files": [],
    "exclude": [
        "node_modules"
    ]
}

Perhaps this will explain why everyone has mixed results?
