Add config to output lowercase about javascript HOT 7 CLOSED

The issue I see is that Crockford's base32 is intended to be written in uppercase, so a lowercase form of ULID (LULID?) would be better served by a different encoding such as z-base-32.

When decoding, upper and lower case letters are accepted

So an ulid decoder should support upper and lower case anyways ...

You're right – it turns out ULID is already specified as case-insensitive. Are you proposing changing the default or just making it configurable? Your original comment contradicts the issue title.

Sry for the unclear wording 😅. I just want it to be configurable. The default should probably remain upper case, as this also seems to be what crockford uses as default.

from javascript.

I'm open to outputting/formatting as lower-case, since the spec is case-insensitive. If you'd like to submit a PR, I'd be happy to accept it.

Created a PR: #34

@adius, on reflection, I have decided that I will not be accepting this PR. The alternative is incredibly simple, and what we would use internally to make a ULID lowercase, so I would recommend for you to it instead:

ulid().toLowerCase()
