Short but unique IDs.
- Short but unique IDs
- The possibility of collision is impossible
- Suitable for distributed systems
- Suitable for sorting and database indexes
- Snowflake IDs developed by Twitter (X) can be generated
- Symbolic IDs can be generated like YouTube's video IDs
You can install it as follows.
// NPM
npm install uuniq
// PNPM
pnpm install uuniq
// Yarn
yarn add uuniq
// Bun
bun add uuniq
// Deno

import { Snowflake, Symbolic } from "uuniq";
new Snowflake(options?)
Snowflake IDs developed by Twitter (X) in 2010. Unique IDs can be generated in distributed systems by specifying Place IDs.
Parameter Default Description options SnowflakeOptionsDefault SnowflakeOptions (optional)
Constructor's options.Example:
const SnowflakeIDs: Snowflake = new Snowflake();
new Symbolic(options?)
Unique IDs like YouTube's video IDs. Unique IDs can be generated in distributed systems by specifying Place IDs.
Parameter Default Description options SymbolicOptionsDefault SymbolicOptions (optional)
Constructor's options.Example:
const SymbolicIDs: Symbolic = new Symbolic();
Snowflake.generate()
Generate Snowflake IDs developed by Twitter (X) in 2010.
Parameter Default Description returns String
Example:
SnowflakeIDs.generate(); // "102604921389056" SnowflakeIDs.generate(); // "102604921389057"
Snowflake.resolve(id)
Resolve the previously created ID. For this, the epoch
and place_id
values in the Constructor must be correct.
Parameter Default Description id String
ID to be resolved.returns SnowflakeResolve
Example:
SnowflakeIDs.resolve("102604921389056"); /* { created_at: "2025-03-14T11:35:07.409Z", place_id: 0, sequence: 0 } */
Symbolic.generate()
Generate unique IDs like YouTube's video IDs.
Parameter Default Description returns String
Example:
SymbolicIDs.generate(); // "T8Qu56ki" SymbolicIDs.generate(); // "T8Qu56kj"
Symbolic.resolve(id)
Resolve the previously created ID. For this, the epoch
and place_id
values in the Constructor must be correct.
Parameter Default Description id String
ID to be resolved.returns SymbolicResolve
Example:
SymbolicIDs.resolve("T8Qu56ki"); /* { created_at: "2025-03-14T11:36:05.528Z", place_id: 0, sequence: 0 } */
