What is NanoID ?

NanoID is a tiny, secure URL-friendly unique string ID generator. It uses cryptographically strong random APIs that guarantees proper distribution of symbols. It is also compact in size. 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.

NanoID installation

pip install nanoid

from nanoid import generate

generateId = generate()
print(f"Generated ID: {generateId}")

To check the safety of your ID length in ID collision probability calculator

If you want to reduce ID length (which will increase collisions probability), we can pass the length as an argument.

from nanoid import generate

generateId = generate(size=10)
print(f"Generated ID: {generateId}")

Custom Alphabet or Length

If you want to change the ID's alphabet or length we can use the internal generate module by passing a character list and size.

from nanoid import generate

charactersToUse= '0123456789abcdef'
outputSize = 12
generateId = generate(charactersToUse, outputSize)
print(f"Generated ID: {generateId}")

Note

Symbols -,.() are not encoded in the URL. If used at the end of a link they could be identified as a punctuation symbol.
