TypeIDs are a modern, type-safe, globally unique identifier based on the upcoming UUIDv7 standard. They provide a ton of nice properties that make them a great choice as the primary identifiers for your data in a database, APIs, and distributed systems. Read more about TypeIDs in their spec.

This is the official JavaScript / TypeScript implementation of TypeID by the jetpack.io team. It provides an npm package that can be used by any JavaScript or TypeScript project.

Using npm:

npm install typeid-js

Using yarn:

yarn add typeid-js

Using pnpm:

pnpm add typeid-js

To create a random TypeID of a given type, use the typeid() function:

import { typeid } from 'typeid-js';
const tid = typeid("prefix");

The prefix is optional, so if you need to create an id with a type prefix, you can do that too:

import { typeid } from 'typeid-js';
const tid = typeid();

In addition to the typeid() function, there's also a TypeID class that can be used to encode/decode from other formats.

For example, to parse an existing typeid from a string:

import { TypeID } from 'typeid-js';

const tid = TypeID.fromString("prefix_00041061050r3gg28a1c60t3gf);

To encode an existing UUID as a TypeID:

import { TypeID } from 'typeid-js';

const tid = TypeID.fromUUID("prefix", "00000000-0000-0000-0000-000000000000");

The full list of methods includes:

• getType(): Returns the type of the type prefix
• getSuffix(): Returns uuid suffix in its base32 representation
• toString(): Encodes the object as a string, using the canonical format
• toUUID(): Decodes the TypeID into a UUID string in hex format. The type prefix is ignored
• toUUIDBytes(): Decodes the TypeID into a UUID byte array. The type prefix is ignored
• fromString(str): Parses a TypeID from a string
• fromUUID(prefix, uuid): Creates a TypeID from a prefix and a UUID in hex format
• fromUUIDBytes(prefix, bytes): Creates a TypeID from a prefix and a UUID in byte array format
