Throw error of unrecognized `type` in `.auth({ type })` about auth-app.js

[gr2m]

I'd like to throw an Error in the code, and not rely on the TypeScript definitions. hen using the auth strategy with Octokit, the octokit.auth() method does currently not inherit the types

at TS level does not have much sense since an invalid type is impossible to reach when using @octokit/auth-app package.

That is a known limitation right now. See octokit/core.js#32 and https://github.com/octokit/rest.js/issues/1562#issuecomment-582678977. It comes back to the idea of having a global Octokit namespace that plugins can extend, it's a bigger project. I want to create a high level issue for this for further discussion. This will also address the ability to define custom event webhooks, for example

Hi @gr2m

Taking a look into this.

Trying to reproduce it with TypeScript, the compiler complains about it:
https://codesandbox.io/s/octokit-auth-app-with-typo-lsg69

Do you have more details on how to reproduce this?

Drafted this PR (#249) but at TS level does not have much sense since an invalid type is impossible to reach when using @octokit/auth-app package.

Checking at @octokit/core package, I found some TODOs which probably are the cause of the problem:

• https://github.com/octokit/core.js/blob/8d694c00a3a44c61c2fbb4d88e49e4a2d33fb50c/src/types.ts#L8-L11
• https://github.com/octokit/core.js/blob/8d694c00a3a44c61c2fbb4d88e49e4a2d33fb50c/src/index.ts#L119-L123
• https://github.com/octokit/core.js/blob/8d694c00a3a44c61c2fbb4d88e49e4a2d33fb50c/src/index.ts#L180-L181

And checking at @octokit/types seems we are not exposing AuthTypes. What we would need is:

auth-app.js/src/types.ts

Lines 141 to 144 in f008655

	export type AuthOptions = InstallationAuthOptions &
	OAuthOptions & {
	type: "app" | "installation" | "oauth";
	};

Not sure how to proceed here:

• To place AuthOptions in @octokit/types (and @octokit/auth-app and @octokit/core consume them from there) (?)
• To add @octokit/auth-app as dependency for @octokit/core and consume AuthOptions directly (?)
• Any other option I'm not considering (?)
