Summary of Changes

Hello @MinCrohn, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request refactors the project's unique identifier generation mechanism by migrating from the uuid library to nanoid. This change aims to leverage nanoid's benefits, such as its compact size, customizable alphabet, and direct length control, while maintaining strong randomness properties. The core uid utility function has been re-implemented to generate 15-character alphanumeric IDs, with corresponding updates to dependency management, build configurations, and unit tests to ensure correctness and robustness.

Highlights

• Dependency Migration: The uuid package has been replaced with nanoid for generating unique identifiers across the project.
• ID Generation Logic Refactor: The uid utility function now leverages nanoid's customAlphabet to produce 15-character alphanumeric IDs, offering enhanced control over ID length and character set.
• Build Configuration Update: nanoid has been explicitly added to the external dependencies in rollup.config.mjs to optimize bundling.
• Test Enhancements: Unit tests for the uid function were updated to reflect the new 15-character ID length and significantly increased the uniqueness test coverage from 1,000 to 100,000 iterations.

Code Review

This pull request successfully replaces uuid with nanoid for generating unique identifiers, which is a good move for performance and bundle size. My review focuses on a key performance optimization in the new uid function and a minor correction in the test suite to improve clarity and maintainability. Overall, the changes are good, but the suggested improvements will make the implementation more robust.

[gemini-code-assist]

Calling customAlphabet inside the uid function is inefficient because it recreates the generator on every invocation. For better performance, you should create the nanoid generator once at the module level and reuse it. This will be particularly beneficial if uid is called in a loop or frequently.

Suggested change

	import { customAlphabet } from 'nanoid';
	export const uid = () => uuidv4().replace(/-/g, '').substring(0, 12);
	// uuidv4 provides completely random values. (CSPRNG)
	// nanoid includes uppercase alphabets, making it more secure (completely random like uuidv4).
	// nanoid allows direct length adjustment in the function.
	export const uid = () =>
	customAlphabet(
	'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz',
	15,
	)();
	import { customAlphabet } from 'nanoid';
	// uuidv4 provides completely random values. (CSPRNG)
	// nanoid includes uppercase alphabets, making it more secure (completely random like uuidv4).
	// nanoid allows direct length adjustment in the function.
	const nanoid = customAlphabet(
	'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz',
	15,
	);
	export const uid = () => nanoid();

While this assertion is correct, the test description on line 6 is misleading. It states should create a UUID string of length 8, but the test checks for a length of 15. Please update the test description to should create a UUID string of length 15 for consistency.
