Code Help Node JS
1

Sorry for dumb question if it is, but how can i get user IP from request on my NodeJs express app?

req.socket.remoteAddress or X-Forwarded-For wich used in request-ip package doesnt work here on Replit, it send me only server IP i guess.

Is it use proxy or load balancer here? If yes, can you guys please provide some information how can i get user ip other way

Why do you need to get your users IP?

I use weather block on my website and i need to show current weather in user location.

Strange question, anyway. Any website logs users ip for stats, targeting or else

4

Couldn’t you just ask them for their location instead? Unless someone else here knows how to get the IP.

yeah, i already ask user for location if they press on location button, but i want to implement some feature to get it instantly, and not disturb with notification or so

Try using the first IP sent in X-Forwarded-For

Have you tried using req.socket.remoteAddress or X-Forwarded-For directly?

On my endpoint that fetches your IP Address (https://api.valiantwind.dev/get-ip-address) I use this:

router.get("/get-ip-address", async (req: Request, res: Response) => {
	const ip = req.headers["x-forwarded-for"] || req.socket.remoteAddress
	res.end(ip)
})

That might work for you instead of using request-ip.

The X-Forwarded-For header can contain user-provided information, so you should definitely parse it.

thanks man, but i already tried all of this

req.headers[‘x-forwarded-for’]
req.clientIp
req.ip
req.socket.remoteAddress

i already tried from all browsers, all devices , wifi/4g doesnt metter.

and all the time in results i have not my ip or undefined

can combined app be the reason of it?

i was deployed combined app nodejs/react

Can you check and see if pasting https://api.valiantwind.dev/get-ip-address into the url bar returns your ip address? I just want to check and see if it works for you. It’ll help me solve your issue.

yeah, it returns mine, and if i use inbuilt Webview on replit - its also return mine,

but when i tried to use my domain i linked - it return US ip adress (im not from US)

12

Can I see the code you’re using currently?

13

yeah, i guess i found the problem.

when i use domain that gave me Replit (this long ass link) - it returns my ip

but when i use custom domain i linked to this project - it returns wrong

That’s strange, because AFAIK custom domains aren’t supported to do that (my endpoint is an example of this).

I’m glad you’ve found the issue :slight_smile:
