Describe the problem you'd like to have solved

In V4, it is not possible to redirect users to a specific destination when we log users out.

Describe the ideal solution

Allow users to provide a returnTo or post_logout_redirect_uri as part of the handleLogout process.

nextjs-auth0/src/server/auth-client.ts

Line 301 in f8dd690

url.searchParams.set("post_logout_redirect_uri", this.appBaseUrl)

An idea is to add a returnTo to the post_logout_redirect_uri with a fallback to the appBaseUrl.

- url.searchParams.set("post_logout_redirect_uri", this.appBaseUrl)^
+ url.searchParams.set("post_logout_redirect_uri", returnTo || this.appBaseUrl)

This should ultimately allow users to do something like this

/auth/logout?returnTo=https%3A%2F%2Flocalhost%3A3000%2Fanother-logout-destination

Hi @brandicph 👋 We can definitely allow for different logout URLs to be specified via the returnTo as you mentioned — the only thing to note is that would require registering each URL in the Allowed Logout URLs of your client. Would that work for your use case?

@guabu that is perfect 👌 np. we are used to the process of registering each URL in the client's Allowed Logout URLs. 🤙

Sounds good, I'll get that added in the next release this week. I'll keep you posted once it's been added!

Hey @brandicph 👋 We've just cut a new release which should now allow you to pass the logout URL in the returnTo query parameter. The README docs have also been updated to reflect that.

Please feel free to upgrade to the latest and give it a shot: npm i @auth0/[email protected]
