core-dts

TypeScript will support all proposals above stage-3.
But there are always some gap between TypeScript support and proposal progress.
And sometimes we want to use proposals within stage-3 (e.g. Iterator helper) because we may use polyfill.

In this case, we have to write those declarations by our own. But with core-dts, we can use these proposal with additional declaration files.

Install

pnpm add core-dts -D

Setup

Set add core-dts into types in compiler options.

{
  "compilerOptions": {
    "types": ["core-dts"]
  }
}

Proposals

Default proposals are above stage-3. If you want to use something like stage-2 proposal.

{
  "compilerOptions": {
    "types": ["core-dts/src/proposals/stage-2"]
  }
}

Or you want to use some specific proposal.

{
  "compilerOptions": {
    "types": ["core-dts/src/proposals/stage-2/iterator-helper.d.ts"]
  }
}
