Module not found: Can't resolve 'dns'

[nicolasiensen]

Whenever I try to require('replay') in my app, I get an error saying:

./~/replay/lib/patch_dns_lookup.js
Module not found: Can't resolve 'dns' in '/Users/nicolasiensen/Projects/t-inbox-client/node_modules/replay/lib'

I'm using create-react-app to abstract the Webpack configuration, the replay version is 2.1.2 and the node version is 7.10.0.

I've tried to install dns package, but it fails since one of its dependencies requires a very old version of node:

yarn add dns
...
error hawk@0.10.2: The engine "node" is incompatible with this module. Expected version "0.8.x".
error Found incompatible module
...

Is this a known issue? Why dns is not listed in the replay dependencies? Thanks in advance!

The dos module is part of Node.js.

Thanks for the answer, @assaf. But I still don't understand why dns can't be found since it is part of Node.js 😕

Faced the same problem, write if you could solve

You simply can't have nodemailer in the frontend. Nodemailer and other projects depending on it (i.e. gmail-send) are made for nodejs use in the backend.

Instead, you should look into either using a 3rd party smtp service like AWS-SES or make your own by using nodemailer in the backend and the front end would invoke it through something like https requests.
