How do you redirect if a token has expired?

[jacobtipp]

This seems a bit trivial, however, I have not used JWT with Hapi.js before. Currently I am testing my auth flow by having a user login via a form, and wrapping a cookie with a JWT back to the client. For testing purposes I'm making the token expire in 1 minute. I want to be able to redirect to the /login view if the token has expired. The default behavior for this plugin seems to be a 401 response, which makes sense but if I want to capture this and redirect, I'm not exactly sure how to do it. I've tried setting ignoreExpiration to true, but I believe validateFunc isn't responsible for redirects of any kind.

Any help would be appreciated.

good question @traducer
yes, the validateFunc is not responsible for re-direct.
Typically people write an onPreResponse extension plugin for their Web Apps which allows them to intercept any/all errors and show the relevant page.
Let us know if you need a working example of this.

@traducer & @goncalvesr2 we have just released an update to hapi-error which helps you easily redirect to any url you define if the Auth check fails (i.e. statusCode 401) see: https://github.com/dwyl/hapi-error#redirecting-to-another-endpoint

Just chiming in here to say I followed @nelsonic 's advice with utilizing an onPreResponse func to intercept the 401, clear the cookie, and redirect. 👍 thanks.
