Js-cookie: Cookie name with slash

[czebe]

Describe the bug
Cookie name with slash / character is escaped to %2F
Eg. user/123=foo becomes user%2F123=foo

I believe the forward slash character is allowed in the cookie key.

It's unclear why you're passing key here as the converter expects a single parameter:
value = converter.write(value, key)

And on the next line:
https://github.com/js-cookie/js-cookie/blob/b1d83a073525e00f87d8b4effa4804b8cb741f12/src/api.mjs#L21

Perhaps it would be better to have:
key = converter.write(key)

Expected behavior
Cookie name preserves the original forward slash character.

RFC 6265 defines the cookie name as token, which in turn is defined in RFC 2616 as follows:

       token          = 1*<any CHAR except CTLs or separators>
       separators     = "(" | ")" | "<" | ">" | "@"
                      | "," | ";" | ":" | "\" | <">
                      | "/" | "[" | "]" | "?" | "="
                      | "{" | "}" | SP | HT

So a / needs to be encoded.

Reopening as valid, see discussion in #595.

I've bumped the v3 beta containing the new implementation.
