[Twitch] no way to pass state from request

[dafreaki]

there is currently no way (or at least documentation) to pass the state via @UseTwitchAuth() using the request query params

[mjangir]

@dafreaki What exactly your use case is?

[icameron]

being able to pass the state of the request i.e a nonce or the referring url basically something that the callback can consume please see https://dev.twitch.tv/docs/authentication/getting-tokens-oauth

Parameter	Required?	Type	Description
client_id	Yes	String	Your app’s registered client ID.
force_verify	No	Boolean	Set to true to force the user to re-authorize your app’s access to their resources. The default is false.
redirect_uri	Yes	URI	Your app’s registered redirect URI. The authorization code is sent to this URI.
response_type	Yes	String	Must be set to code.
scope	Yes	String	A space-delimited list of scopes. The APIs that you’re calling will identify the scopes you must list. You must URL encode the list.
state	No	String	Although optional, you are strongly encouraged to pass a state string to help prevent Cross-Site Request Forgery (CSRF) attacks. The server returns this string to you in your redirect URI (see the state parameter in the fragment portion of the URI). If this string doesn’t match the state string that you passed, ignore the response. The state string should be randomly generated and unique for each OAuth request.

I have modified the Authguard to support dynamic values for state.

  getAuthenticateOptions(context: ExecutionContext): IAuthModuleOptions {
    const request = context.switchToHttp().getRequest()
    return {
      state: Buffer.from(JSON.stringify(request.query)).toString('hex'),
    }
  }
