How To Get User I.P Address In SvelteKit

SvelteKit now makes it super easy to get the IP address of a user.

What is an IP address?

An IP address is a unique identifier for a device on the internet or a local network. It is used by the internet to distinguish between computers. It is a series of integers separated by periods, such as 192.168.42.1. You may learn more about IP addresses here.

Extracting an IP address in SvelteKit

In SvelteKit, you can get the IP address of your users through endpoints, server-only load functions, and server hooks. Any function parameter that has a type of RequestEvent allows you to get the IP address by deconstructing the getClientAddress function from the object. If this function is called, it returns the user's IP address.

// +page.server.js
  export const load = { getClientAddress } => {
    const ip = getClientAddress()
  }

Do note that, in dev mode, the value you will get for getClientAddress will always be 127.0.0.1, because you are using localhost, and creating a network on your own computer.
