TypeScript errors with MappedInteractionTypes

Which package is this bug report for?

discord.js

Issue description

Note: This is not a duplicate of #7924, strictNullChecks are enabled!

1. Create a new project using yarn init -y
2. Install discord.js using yarn add discord.js
3. Install typescript and node-types using yarn add -D typescript @types/node
4. Create tsconfig.json and index.ts from the codesample
5. Run yarn tsc --noEmit
6. Observe errors in discord.js/typings/index.d.ts

A workaround for this is using skipLibCheck but I’d rather not have to do that since I believe that including the libraries in typechecking is valuable to spot missing external dependencies (like polyfills for DOM API or WebSocket, etc).

---

One more note regarding the dev build (yarn add discord.js@dev, version number down below): That one does not show the errors mentioned above but a handful other ones regarding the new Builders.

Any estimates when a new version without library internal typeerrors is going to be released?

No ETA sadly.

I’m actually having the same issue, and setting skipLibCheck to true isn’t going to do for me in the long run.

But… I don’t have a choice right now, so that will do. At the moment, all my types are just going to be linted and not checked by TypeScript.

Having the same issue with strictNullChecks enabled.

strictNullChecks won’t do anything and one does not need to set skipLibCheck to true. Simply override discord-api-types to 0.37.14 in your package.json:

{
  "overrides": {
    "discord-api-types": "0.37.14"
  }
}
