Description
Sorry to bother about IE support 😇
Describe the bug
In react-scripts 3.3.0 de webPackDevServer setup was switched from SockJS to WebSocket. see PR
Since the url.format returns an URL something like ws:localhost not ws://localhost, it will throw an Syntax Error on IE.
Environment
Windows 8.1, node 10, npm 6, ie11
Steps to reproduce
- Install create-react-app w/ react-scripts 3.3.0
- Import react-app-polyfills (stable & ie11)
- Set browserslist to include "IE 11" in development mode aswell
- Run
npm start - Open the dev server in IE
Expected behavior
The dev-server should work on IE aswell.
Actual behavior
A syntax error gets thrown.
