Accessing client IP address in a query/mutation

Good day. Any help would be appreciated, as I am fairly new to Convex. Is there a way to expose HTTP headers, such as for obtaining the IP address in the example below? Or is an httpAction required for this use case?

const registerClient = mutation({
  args: { userAgent: v.string() },
  handler: async (ctx, { userAgent }) => {
    // get ip address from 'x-forwarded-for' header
    await ctx.db.insert('client', { userAgent, ip })
  }
})

const registerClient = mutation({
  args: { userAgent: v.string() },
  handler: async (ctx, { userAgent }) => {
    // get ip address from 'x-forwarded-for' header
    await ctx.db.insert('client', { userAgent, ip })
  }
})

What's your goal with this? Currently the incoming IP address is not exposed even in an httpAction.

MegaHydronicsOP•9mo ago

It's for simple analytics of users' geographical distribution.

const response = await fetch(`https://ipinfo.io/${ip}/json/?token=${process.env.ipinfoToken}`)

const response = await fetch(`https://ipinfo.io/${ip}/json/?token=${process.env.ipinfoToken}`)

If Convex were to expose as an extra header or ctx.meta.geo property would you want the geographical location directly, or still the IP address?

MegaHydronicsOP•9mo ago

For my use case, ctx.meta.geo would be great.

For my use case, I’m looking to implement an IP-based rate limiter in Convex. This would require reading the client’s IP address within an action. Is there currently any way to access the IP address server-side in Convex without having to rely on the client to send it?

@ballingt I would definitely use this too. To rate limit on IP address I have to use a http endpoint. I think for me I'd probably want the raw details from the http request (presumably) that happens when initating the web socket

@ballingt I would use it as well, also to incorporate more robust security checks, like automatic malicious query detection, and IP based restriction of functionality. I feel like this is a must-have, a lot of use cases, and in many cases IP address is required by law or for mere functionality (e.g., Stripe).
