How many times per day you swear when writing React code with TypeScript?..
Today I got this:
Type 'MutableRefObject<HTMLInputElement | undefined>' is not assignable to type 'LegacyRef<HTMLInputElement> | undefined'.
Type 'MutableRefObject<HTMLInputElement | undefined>' is not assignable to type 'RefObject<HTMLInputElement>'.
Types of property 'current' are incompatible.
Type 'HTMLInputElement | undefined' is not assignable to type 'HTMLInputElement | null'.
Type 'undefined' is not assignable to type 'HTMLInputElement | null'.ts(2322)Hmmm, so my input’s current property is not compatible. What exactly does it mean? I already declared my ref like this:
const inputRef = useRef<HTMLInputElement>();Pulling my hair off, trying all kind of HTMLBlaBlaBlaElements, all I had to do was…
const inputRef = useRef<HTMLInputElement>(null);Imagine if TypeScript would be able to actually give us proper hints. (where’s the AI that all the people keep talking about??)
Did you know that I made an in-browser image converter, where you can convert your images without uploading them anywhere? Try it out and let me know what you think. It's free.
