Typescript errors

[ericehamlin]

Hi! 👋

Firstly, thanks for your work on this project! 🙂

Today I used patch-package to patch react-dropzone-uploader@2.11.0 for the project I'm working on.

When using this library with typescript, there were a couple of errors during compilation resulting from assigning potentially undefined values to typed values.

Here is the diff that solved my problem:

I look into the code deeply. I have a "soft ts-compiler" (strict false, null and no strict on null/undefined) and raise big error when delete it.

all "@ts-ignore " is an issue itself because javascript code can works with typescript like this.

im working to make modern dropzone with functions only (working with react v18.2, and will have less feature, I trying to compact the code also) ... so i'll post my code as alternative ...

I thinking this issue pointing the root of all evil....

PS: maybe at all, i will make real basic dopzone with W3C and MDN content lol : /
