Hybrid ID GeneratorCompact IDs.
Explicit machine fields.

Generate configurable bigint identifiers in Node.js and browsers. Encode them for URLs, inspect their fields, and check their age.

Get started

Explore the API

Choose your layout

Allocate timestamp, machine, random, entropy, and sequence fields. Defaults use 81 bits, with 4,096 machine values.

See the format

Store without precision loss

Keep the bigint in memory. Use decimal strings, Base62, Base32, or Base64 integer digits for transport and storage.

Choose an encoding

Understand the guarantees

Sequence state handles clock rollback and overflow within one generator. Coordinate machine IDs and account for process restarts.

Read the guarantees

Node.js and browsers

CommonJS for Node, an ES module for bundlers, and a browser global for script tags. No runtime npm dependencies.

Pick your runtime

Generate an ID

import { HID } from 'hybrid-id-generator';

const generator = new HID({ machineId: 1, useCrypto: true });
const id = generator.nextId();
console.log(id.toBase62());
console.log(generator.info(id));

Use a distinct machine ID for each concurrent generator. The format is custom; choose a standard UUID when your storage or integrations require UUID compatibility. IDs identify records; application authorization controls access to them.
