Feature request: Allow the user to control the Callback path

[totto2727]

Prerequisites

• I have searched the repository’s issues, Kinde community and public roadmap to ensure my feature request isn’t a duplicate
• I have read the contributing guidelines
• I agree to the terms within the code of conduct

What is the problem you’re trying to solve?

Unable to control redirection to callback API.

Details

• Callback API paths are hard-coded.

  • kinde-remix-sdk/src/handle-auth.js

    Line 20 in ff037e2

    redirectURL: config.siteUrl + "/kinde-auth/callback",

• SDK for TS cannot override redirect_url from query parameters due to implementation using SearchParams.append.
  • Kinde's API seems to prefer the first redirect_url (defined by the SDK)
  • https://github.com/kinde-oss/kinde-typescript-sdk/blob/a9f596bd136ee0412d3eb3b4e3c8e1aca1473421/lib/sdk/oauth2-flows/AuthCodeAbstract.ts#L310-L317

What solution would you like to see?

Allow developers to control which callback APIs to redirect.

solution

• Pass via process.env.
• Pass the redirectURL property directly to handleAuth.
  • Passing a config object with redirectURL property.
  • Pass via option of handleAuth.

Additional information

• I have considered modifying the authentication URL generation logic in the SDK for TS and overriding it via a query parameter, but I feel that extending the configuration of the SDK for Remix would be a more straightforward implementation.
• I found similar hard coding in the SDK for Next.js. Is it designed under the assumption that a specific path is set as a callback? If so, I felt it should be clearly stated in the SDK documentation.

I am ready to commit once the plan is in place!
