Need to replace check for WEBPACK_DEV_SERVER to WEBPACK_DEV_SERVE when going to webpack-dev-server v4

[justin808]

Reminder for a future upgrade of the webpack-dev-server

process.env.WEBPACK_DEV_SERVER renamed to process.env.WEBPACK_DEV_SERVE in PR 3000 for v4 off webpack-dev-server.

Details

Older code:

https://github.com/webpack/webpack-dev-server/blob/7ee869e17fc3c0db56c8ff44dc1c6b6f03c85c1a/lib/Server.js#L65-L68

Originally added: webpack/webpack-dev-server#1929

Newer, on master:

https://github.com/webpack/webpack-dev-server/blob/master/lib/Server.js#L19-L21

To help with future searches, it's actually process.env.WEBPACK_SERVE (no _DEV_)

This has been fixed in 6.0.0.rc.4.
