Warning in VSCODE: Use caution when using experimental decorators

I have been working on an Angular2-Typescript application and created the project using angular-cli with the command:

ng new myApp

However, I am facing a warning issue when creating a new component with the @Component tag.

I have tried to resolve this problem by referring to this post:

Experimental decorators warning in Visual Studio Code

Unfortunately, the solution provided in the post did not work for me.

Below is my tsconfig.json configuration:

{
"compilerOptions": {
"declaration": false,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"lib": ["es6", "dom"],
"mapRoot": "./",
"module": "es6",
"moduleResolution": "node",
"outDir": "../dist/out-tsc",
"sourceMap": true,
"target": "es6",
"typeRoots": [
  "../node_modules/@types"
  ]
 }
}

The Typescript version being used is: "typescript": "2.0.2"

Answer №1

After some trial and error, I was able to resolve the issue by taking the following steps:

To start off, I upgraded my typescript version using the command below:

$ npm install typescript@next

Next, I made adjustments to my user preferences in vscode by adding the code snippet:

{
  "typescript.tsdk": "node_modules/typescript/lib"
}
