Scoped redirect when using Express.js Routers - redirect

Question

When using Express Routers, a route prefix can be provided:
var router = new Express.Router();
app.use("/scope", router);
Let us say that I have some CRUD routes in my Router.
router.post("/", function(req, res) {
var result = create(req);
res.redirect(result.id);
});
router.put("/:id", function(req, res) {
var result = update(req);
res.redirect(result.id);
});
router.get("/:id", function(req, res) {
var result = findById(req.params.id);
res.render("show.html", {data: result});
});
When requesting to the PUT above, the response is a redirect to "/scope/[id]" as it should be. When requesting to the POST, the response is a redirect to "/[id]" instead of the previous result.
I am not certain where to find the root of the issue, nor how to correct it.

Answer 1

I will answer the question anyway, for the benefit of anyone else who might encounter this issue.
What I suspect your original issue was that, since you had strict mode disabled (Express' default), your client side code was likely POSTing to /scope' (which in non-strict node is the same as/scope/). Within your post handler you did a relative redirect usingres.redirect(result.id). Let sayresult.idis123, then a relative redirect would take you to/123`.
NOTE: Don't forget that Express has little to do with the actual redirects, which are taken care of client-side by the browser.
The issue could have easily been solved by ensuring your client side code POSTed to /scope/, after which a relative redirect to id would take you to /scope/id, just as you expected.
