Typescript cannot find name window or document

For either case:

// or

I get error TS2304: Cannot find name 'window'.

Am I missing something in tsconfig.json for a definition file I should install?

I get the message when running tsc and in vscode


    "compilerOptions": {
        "allowJs": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "jsx": "react",
        "module": "commonjs",
        "moduleResolution": "node",
        "noEmitOnError": true,
        "noImplicitAny": false,
        "sourceMap": true,
        "suppressImplicitAnyIndexErrors": true,
        "target": "ES2016",
        "typeRoots": [
    "exclude": [

My Answer: For use with tsconfig.json I target es5 and use lib: ["es2015", "dom"]



It seems that the problem is caused by targeting ES2016.
Are you targeting that for a reason? If you target es6 the error will probably go away.

Another option is to specify the libraries for the compiler to use:

tsc -t ES2016 --lib "ES2016","DOM" ./your_file.ts

Which should also make the error go away.

I'm not sure why the libs aren't used by default, in the docs for compiler options it states for the --lib option:

Note: If --lib is not specified a default library is injected. The default library injected is:
? For --target ES5: DOM,ES5,ScriptHost
? For --target ES6: DOM,ES6,DOM.Iterable,ScriptHost

But it doesn't state what are the default libraries when targeting ES2016.
It might be a bug, try to open an issue, if you do please share the link here.



"lib": ["dom"]

in tsconfig.json


  "compilerOptions": {
    "lib": ["es5", "es6", "dom"],
    "outDir": "./dist/",
    "sourceMap": true,
    "noImplicitAny": true,
    "module": "commonjs",
    "target": "es6",
    "moduleResolution": "node",
    "jsx": "react"
  "include": ["./src/**/*"]
