TypeScript Cannot find name 'window'

Question

In my Meteor/React project I have the following line:

let gameId = window.prompt("Please enter the ID of the game you wish to load.");

TypeScript gives the transpiling error Cannot find name 'window'. I am using barbatus/typescript, with default compiler options:

{ "module": "commonjs", "target": "es5", "moduleResolution": "node", "experimentalDecorators": true, "emitDecoratorMetadata": true, "sourceMap": true }

I tried creating a tsconfig.json in the root of my Meteor project, copying the above compiler options but appending the line:

"lib": ["es2015", "dom"]

However, the error remains.

Please add your tsconfig.json to your question, even if it's in the link — Nitzan Tomer

can you try after adding "declare var window: any;" in you code — Amit kumar

are you sure you add compilerOptions in tsconfig.json as compilerOptions property,not the root json. — holi-java

I added "dom" to the lib compilerOptions in tsconfig.json，then this problem has been resolved.

In addition to the answer above in your tsconfig file, you need to set the "lib" property to include "dom".

{
  "compilerOptions": {
    // rest of your config
    "lib": ["dom"] // Add this line
  }
}
