In Hapi.js can I redirect to a different endpoint and set a statusCode?

If a user is not authenticated to view a particular route (e.g:

we have tried the following code:

const statusCode = request.output.payload.statusCode;

if(statusCode && statusCode === 401) {

The redirect works when we remove the

Answer Source

Here's the HapiJS source that's causing you grief (lib/response.js:320):

internals.Response.prototype.redirect = function (location) {

    this.statusCode = 302;
    this.temporary = this._temporary;
    this.permanent = this._permanent;
    this.rewritable = this._rewritable;
    return this;

As you can see, by using reply.redirect() Hapi is already replying a 302 code. You'll need to decide whether to reply with a 401 and redirect on the front end, or use the Hapi redirect and accept that it conforms to the protocol standards.

As an answer to the best practice bit, yes, Hapi is doing exactly what is expected when a server forces a redirect (302 Redirect). In order to use a 401 response, the best practice is to redirect on the client side as if you were simply navigating to the route normally.

Edit: For reference, the reply.redirect() function definition (lib/reply.js:145) is simply

return this.response('').redirect(location);
