ai/nanoid

NanoID is a library for generating unique, non-sequential identifiers, offering both secure and non-secure generation modes with support for custom alphabets and sizes. It provides a command-line interface for quick usage and includes an optimized URL-safe alphabet designed to improve compression efficiency. The system is built as a modern ESM package with comprehensive testing, benchmarking, and browser-based visualization tools to verify randomness and performance.

A new executable CLI script (bin/nanoid.js) is introduced, allowing users to generate NanoIDs directly from the command line. The tool supports the --version and --help flags for metadata, and accepts -s/--size and -a/--alphabet arguments to customize the generated ID's length and character set, providing a convenient interface for quick ID generation without writing code.

Introduces a new non-secure random ID generator accessible via the 'nanoid/non-secure' entry point, designed for environments where hardware random generators are unavailable. This addition includes both the JavaScript implementation (index.js) and TypeScript definitions (index.d.ts), exposing the nanoid and customAlphabet functions with an optional size argument and generic type support for opaque ID types.

This release fixes documentation issues and updates the development environment. The core library code (index.browser.js, nanoid.js) remains unchanged from v6.0.0, but the README and its translations (Arabic, Indonesian, Japanese, Korean, Russian, Chinese) have been refreshed. The project has migrated its CI from Travis CI to GitHub Actions (indicated by the removal of .travis.yml and addition of .devcontainer.json) and switched its package manager from Yarn to pnpm (evidenced by the new pnpm-workspace.yaml and updated .npmignore). Additionally, the code formatting tooling has been updated to use oxfmt/oxlint instead of Prettier/ESLint, and the JSR package configuration (jsr.json) is now included.

The url-alphabet module now exports a character set ordered specifically to improve compression efficiency for both gzip and Brotli. By arranging the \A-Za-z0-9\_-\ symbols to leverage common references in gzip back-references (such as 'use', 'andom', 'rict') and Brotli default dictionary words (such as 'bush', 'jack', 'mind', 'very', 'wolf'), the output generated by this alphabet will result in smaller payload sizes when compressed.

Add browser demo page with benchmark and distribution visualization; Added comprehensive test suite and benchmarking infrastructure.

The project has been upgraded to version 6.0.1, shifting the package type to ESM ("type": "module") and updating the supported Node.js engines to ^22, ^24, or \>=26. The build and linting toolchain has been modernized by replacing ESLint and Jest with oxlint and better-node-test, and the lockfile has migrated from yarn.lock to pnpm-lock.yaml. Development dependencies have been updated to their latest versions, including Vite (^8.3.0), TypeScript (^7.0.2), and size-limit (^14.0.0), while the package size limit has been adjusted to reflect the new 127-byte target for the main nanoid export.
