NanoID is a tiny, secure URL-friendly unique string ID generator.
It's safe. It uses cryptographically strong random APIs that guarantees proper distribution of symbols.
And it's compact. It uses a larger alphabet than the standard UUID (A-Za-z0-9_-), and has a similar number of unique IDs in just 21 symbols instead of 36.
simple() - generate an id of default length (21) using the default character set
local simple = nanoid.simple()
print(simple)generate(size) - generate an id of custom length using the default character list
local generate = nanoid.generate(5)
print(generate)custom(custom_alphs, size) - generate an id of custom length using a custom character set
local custom = nanoid.custom("abcde", 7)
print(custom)
