tsguard.macro - Typescript type guard macro

Babel macro that automatically generates an array of keys from a given object type (very much WIP).

Roadmap

• [x] Implement tests
• [x] Support type references (e.g. keysof<IProps>)
• [ ] Support index accessed types
• [ ] Support imported types

Usage

import keysof from "ts-keysof.macro";

type Person = { name: string; age: number };

const personKeys = keysof<Person>(); // ["name", "age"]
