Empty Dumps

[Yash]

You can create empty Dumps easily,

Having an empty text area and clicking the submit button does not work but you can still create empty Dumps by ctrl/cmd enter

But still since this is markdown,
there are many ways to create an empty looking markdown like empty bold texts

** **

simply .trim() will not be able to recognise these, so you can replace all the * and _ with spaces and then trim to find if empty

hey I would like to work on it

[piyush]

so I have been looking on internet to find ways to create empty string in md and found these
(view in raw format to see the result)

• [](foo) link tag result:
• [//]: # (comment) comment tag result(needs \n between previous line):

• [foo]: bar reference tag result(needs \n between previous line):

so should I handle all this cases? I did wrote some regex for them

• /\[s*?\]\(.+?\)/g
• /\[\/\/\]:\s*?#\s*?\(.*?\)/g
• /\[.*?\]:.+?/g

this handles almost all the edge cases. But we all know regex can easily be exploited so not sure what to do here.
or we can simple do this:

const isValidDump =
      dump
        .replaceAll(" ", "")
        .replaceAll(/\n/g, "")
        .replaceAll(/\t/g, "")
        .replaceAll("*", "")
        .replaceAll("`", "")
        .replaceAll("#", "")
        .replaceAll("[", "")
        .replaceAll("]", "")
        .trim().length > 0;

that works for now!

I was able to create an empty dump using ![]()

[piyush]

this really needs a better solution but for now we can also replace !

[Dhravya Shah]

replace it for checks, hmm yeah, what even is the better solution?

[Dhravya Shah]

any more edge cases?

[Yash]

I can also create empty dumps using []()

this case was mentioned by @piyush-panpaliya , but it wasn't fixed

as in the code here

const isValidDump =
      dump
        .replaceAll(" ", "")
        .replaceAll(/\n/g, "")
        .replaceAll(/\t/g, "")
        .replaceAll("*", "")
        .replaceAll("`", "")
        .replaceAll("#", "")
        .replaceAll("[", "")
        .replaceAll("]", "")
        .trim().length > 0;

[] was replaced, but () wasn't
