AbortController missing in TypeScript

Question

I am trying to use AbortController in TypeScript.

Given this small file:

const controller = new AbortController();

I get the following error from TypeScript compiler:

src/testAbort.ts:1:24 - error TS2304: Cannot find name 'AbortController'.

1 const controller = new AbortController();
                         ~~~~~~~~~~~~~~~

TypeScript has documentation about AbortController. I also found an issue from Github which has been resolved by merging a pull request that contains the type definitions for AbortController. So it should be available.

My tsconfig.json contains:

{
  "compilerOptions": {
    "target": "ES2018",
    "lib": ["ES2018"],
    "allowSyntheticDefaultImports": true,
    "moduleResolution": "node",
    "baseUrl": "src"
  },
  "exclude": ["node_modules"],
  "include": ["src/**/*", "__tests__/**/*", "index.ts"],
  "typeRoots": ["./node_modules"]
}

What I have tried:

• Upgraded to latest TypeScript 3.7.5
• Setting both lib and target options in tsconfig as "ESNext".
• Accessing it through global.AbortController.

It's because you are missing the value DOM in the lib array of your tsconfig.json. If you check the official repo, you will find the AbortController here!
