overwolf-async-types

Async, typed real-time wrapper for the Overwolf API based on the official type definitions.

Installation

To install, run:

npm install overwolf-async-types

Bear in mind that this will take a while as the new type definitions are generated upon installation.

Usage

1. Add the types to your tsconfig.json file:

{
  "compilerOptions": {
    "types": [
      "overwolf-async-types"
    ]
  }
}

2. Call the promisify method before using the Overwolf API:

import { promisify } from 'overwolf-async-types';

promisify();

3. Consume the API using Promises:

const res = await overwolf.windows.obtainDeclaredWindow('main');

4. (optional) Refetch and rebuild definitions:

npx generateOverwolfAsyncTypes

How Does It Work

1. Fetches the latest d.ts files from Overwolf's repo
2. Iterates over the types inside overwolf.d.ts and updates them to use Promises, also updates JSDoc accordingly.
3. Generates promisify code into promisify.js - this code traverses the Overwolf API during runtime and wraps relevant functions in a Promise. It also changes all const enums into regular enums to increase compatibility.

Notes

• After installing/updating/rebuilding, restart your IDE/Typescript Server/ESLint Server to ensure you're working with the newly built definitions.
• To prevent conflicts, make sure to remove Overwolf's types library (@overwolf/types). If you want a solution that uses @overwolf/types instead of fetching the files, make a PR.
• Some Overwolf functions are readonly (e.g. overwolf.io.dir) - Those functions are kept intact, and new functions with an Async suffix are added (e.g. overwolf.io.dirAsync)
• Currently it seems that the official definitions file is not fully up-to-date with the actual API. If you find any discrepancies, open a PR on Overwolf's repo. I have contacted Overwolf and they are working on a way to generate the types out of their codebase to ensure coherence.
• This repo was created to serve my needs - it's not guaranteed to work for you OOTB. If you encounter any issues, don't hesitate to either open an issue or create a PR.
• Currently I'm only traversing overwolf.d.ts, if you feel the need to traverse the other files, open an issue/PR.
