The kind of change this PR does introduce
Current behavior
Previous create-react-app example can work normally. However, the
useEffecthook will work multiple times when a new message arrives.I add two console log to show the problem (line 14 and 26 in Gist).
Socket.IO callback will change the states, so the React component updates and call
useEffectagain.New behavior
I fix this problem by passing a second argument to
useEffect(doc). When states change, don't runuseEffectagain.Other information (e.g. related issues)
Other change: I add the logo and other elements generated by create-react-app.
