Below are the common bugs encountered when coding the web.
1. window.open
You need to call window.open as a direct result of a onclick event (user event)... you can't do something before async, and then on a result of that do the window.open
2. Invalid date in safari
new Date("YYYY.MM.DD HH:mm") // doesn't work in safari new Date("MM.DD.YYYY") // doesn't work in safari
new Date("MM/DD/YYYY HH:mm:ss") // work in safari new Date("MM/DD/YYYY") // work in safari new Date("YYYY/MM/DD") // work in safari
3. Jest tests failing in Pipeline build
Cause: Different time zone than local. Best solution: add TZ=UTC into script test
"test": "TZ=UTC jest"4. Text cannot get line breaks when it is too long
For text that needs line breaks, pay attention to test the case where the text is written contiguous such as: aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
=> Should set css:
word-break: break-word;5. Check number
For value type number to check null or empty, it is not allowed if(value) or value ? a : b Because if value = 0 then if(0) return false
