Global Flags

?readable

Switches from standard uuidv4 format to Readable UUIDs, that are Shakespearean grammatically correct sentences.

Eg. Nertie Irwin Farris the Tighter of Chandlerville reminded Erica Aguistin Maryl and 8 dapper jaguars

?short

Switches from standard UUIDv4 to a Short ID. These ID’s are converted from UUIDv4 ID’s so they are just as unique & colission free.

Eg. rZMRC1FzqYjVLxNN6iKqqq

?ulid

Uses the ulidx package to generate ULID’s.

Eg. 01FB0CCPD8R0H9KAJBFQJDFYJB

?nanoid

Uses the nanoid package to generate ID’s. Supports &len= param to adjust ID length. If this is not a number it will be silently ignored. If used in combonation with bulk api, may fail if len is too long.
