HttpResponse.redirect?

[dalisoft]

Hi @alexhultman

Is there any way like res.redirect(newPath) or similar function? In examples folder i'm didn't see any example.

If there no method, any way realize this?

Thanks

res.redirect is an express thing In any case, if you want to redirect without express

Check the second answer.

[dalisoft]

Solved. Answer here
Thanks @elieobeid7

[dalisoft]

Reopen because didn't solved as getting absolute url isn't possible

[elieobeid7]

You're trying to redirect the frontend right? just do

window.location.href = "https://example.com/"

[dalisoft]

@elieobeid7 No, only backend. I know how-to redirect front

[elieobeid7]

You could use this

https://www.npmjs.com/package/redirekt

[dalisoft]

I can redirect to any url, except for backend, i want get url of my backend or having similar to .redirect which redirects auto /path to http://backend.tld/path

Why don't you use express if you think express would solve the issue? It's okay to just use it for redirect, or maybe ask on stackoverflow.

I'm not sure the issue here but I'm not sure, I'm new here. What I would do is install express if I'm sure that express solves the problem.

You see this library is an alternative to socket.io, in socket.io you can't do redirects, in websockets you can't do that either, so I don't think this library can do that, but the owner knows more than I do, so you could wait for his reply about what this library can and cannot do.

[dalisoft]

This library does more than Socket.io does and @alexhultman made the fastest web-server for Node.js ever have (fix me if i'm wrong).
I'm built new Express alternative, you can see here and it's fast, not fast as uWebSockets.js, but very fast.
I'm trying give uWebSockets.js users familiar API (Express-like API) and then users can move to uWebSockets easier, because they see source code and understands how it works, how it wrapped and etc.

[elieobeid7]

Ah kudos! hopefully alex would help you more than I can :)

[dalisoft]

I hope too, thank you for help @elieobeid7 :)

[elieobeid7]

btw in the example i showed

https://stackoverflow.com/questions/17898183/node-js-301-redirect-non-www-without-express/25236904#25236904

the guy redirects to an absolute url, not sure why it's isn't working with you

res.writeHead(301, {"Location": "http://example.com"});

[dalisoft]

The problem comes when i'm trying to use relative urls, because uWebSockets.js req.getUrl() doesn't return the Absolute URL, an Relative URL.
For .redirect need Absolute URL and where i can get the Absolute URL?

[elieobeid7]

So you want something like req.get('host') in express so you could do req.get('host') + req.getUrl()

so req.get('host') not available?

Alright until alex comes and fix it, here's a little hack, we know that the library runs on localhost + port

What we could do is this

const port = 3000;
const host = 'http://localhost:' +  port.toString() + '/'  // Im not sure if the last backslash is needed or not
const absolute_url = host + req.getUrl()

basically if req.getUrl() gives you something like this

/bla/

then you don't need /, but if it gives you bla/ then you need that.

[dalisoft]

Thanks, little hack already i am did until i am found fix or author answers

From what I understand a redirect is just a response with that 300-ish status and a header with the URL. In that case you already have all the tools for this.

[dalisoft]

Thanks. If wontfix, it is not bad, not everyone uses this method.

[Xetera]

In case anyone is struggling with redirects, the order of the calls matter.

res
  .writeHeader("Location", "https://example.com")
  .writeStatus("302")
  .end();

Will not work but

res
  .writeStatus("302")
  .writeHeader("Location", "https://example.com")
  .end();

will. Not sure if that's intentional but it seems to be the case.

[ghost]

First writeHeader calls writeStatus if not already done, so order matters yes

I think this thread had been answered - it takes a few lines of string concatenation but you do certainly have all the tools. It could be added as a built-in feature if more people would report this but I think it is kind of a high level thing.

[dalisoft]

uWebSockets.js built-in methods are really enough to build full-featured backends and this is not much necessary feature, who needs, some of frameworks which built on top of uWebSockets.js already polyfilled and can be found on GitHub
