Nest: How to get client ip from the request?

[ufosky]

I want to get the client ip address, but I didn't find how to do it.

Not sure exactly where you want retrive this address, but on controller level you have access to req object, through @Request() decorator. You can look for ip either at req.ip, req.connection.remoteAddress or in the headers eg. x-forwarded-for in case your app is behind some proxy.

Hi @ufosky,
The @Rafal2228 solution should work for you. Btw you can use @Req() decorator as well

If somebody stumbles on this, here is working solution using request-ip library.

Install library:

npm install --save request-ip
npm install --save-dev @types/request-ip

Optionally add to main.ts:

app.use(requestIp.mw());

Then define new decorator:

import { createParamDecorator } from '@nestjs/common';

import * as requestIp from 'request-ip';

export const IpAddress = createParamDecorator((data, req) => {
    if (req.clientIp)
        return req.clientIp;
    return requestIp.getClientIp(req); // In case we forgot to include requestIp.mw() in main.ts
});

Now you can use it in controller with @IpAddress() ipAddress.
