Creates a critical dependency when used in webpack build

[vjpr]

apollo-link-ws which is used client-side, imports subscriptions-transport-ws.

This is in a next.js SSR app.

utf-8-validate is a native dep: https://github.com/websockets/utf-8-validate/blob/master/index.js

This appears somewhat consistent with an issue I worked through, and it ended up being my webpack config. Further details here: apollographql/apollo-link#1274 (comment)

However, you're using nextjs? I have an application using nextjs that implements subscriptions with apollo-link-ws and I haven't seen this warning. Are you using a custom webpack config? Maybe you could share some of the code that implements apollo-link-ws?
