Modernize repository: TypeScript migration, npm packaging, and testing infrastructure

[Copilot]

Repository contained duplicate JS/TS code, no build tooling, no tests, and was not npm-ready. This PR transforms it into a production-ready package.

Core Changes

TypeScript Migration

• Removed duplicate JavaScript implementations
• Strict TypeScript with proper typing throughout
• Fixed DOM nesting issues (nested buttons → semantic structure)
• Component modularity: split into AccordionItem, SearchBar, AccordionWithSearch

Build & Distribution

• tsup for dual ESM/CJS output with tree-shaking
• TypeScript declarations auto-generated
• Exports properly configured for package consumers
• ~8KB optimized bundle

Testing Infrastructure

• Vitest + React Testing Library setup
• 13 tests covering core functionality
• CI/CD workflow with security permissions

Documentation

• API documentation with TypeScript examples
• CHANGELOG.md, CONTRIBUTING.md, PUBLISHING.md
• Sample CSS and usage patterns

API Example

import { AccordionWithSearch, AccordionItemType } from '@adjanour/react-components';

const items: AccordionItemType[] = [
  {
    title: 'Settings',
    icon: <CogIcon className="h-5 w-5" />,
    children: [
      { title: 'Profile', path: '/settings/profile' },
      { title: 'Account', path: '/settings/account' }
    ]
  }
];

<AccordionWithSearch items={items} className="nav-menu" />

Package now supports both module systems, includes full type definitions, and is ready for npm publication.

Original prompt

i want to close the loop on this, improve it, fix issues, mordernize it, add docs, polish it, clean it up and package it

Pull request overview

This PR modernizes the repository into a TypeScript-based, npm-packaged React component library with build tooling (tsup), a testing stack (Vitest + React Testing Library), CI workflows, and expanded documentation.

Changes:

• Migrates the AccordionWithSearch implementation to modular, strict TypeScript components and removes legacy JS/old TS duplicates.
• Adds packaging/build tooling (tsup + tsconfig) and npm metadata/exports for dual ESM/CJS distribution.
• Introduces test infrastructure (Vitest/jsdom + RTL), CI workflow, and supporting docs (README/CONTRIBUTING/CHANGELOG/PUBLISHING + examples).

Because items defaults to defaultAccordionItems, importing/using AccordionWithSearch without supplying items pulls in the Heroicons-based defaults and forces a runtime dependency on @heroicons/react. If you want items to be optional, consider lazy-loading defaults, removing icon defaults, or requiring callers to pass items so consumers aren't forced to install Heroicons.

This test doesn't assert anything and uses setAttribute('value', ...) + manual change dispatch, which doesn't reliably emulate React input changes. Since @testing-library/user-event is already in devDependencies (and used elsewhere), use userEvent.type/userEvent.clear and assert that the "No items found" message appears.

[Copilot]

When path is missing for a leaf item, this renders NavLink with to="", which can navigate unexpectedly (typically to the current route) and hides configuration errors. Consider making path required when there are no children (type-level union) or rendering a non-link element / throwing when path is undefined.

[Copilot]

Similarly, AccordionChild uses to={child.path || ''} which can produce an empty route when a child has no path. Prefer requiring path for children in the type model or handling the missing-path case explicitly (render as text/disabled item).

[Copilot]

@heroicons/react is used at runtime (imported by defaultAccordionItems) but is only listed under devDependencies. Because tsup also marks it as external, consumers will get a runtime module-not-found error unless they install it themselves. Move @heroicons/react to peerDependencies (or dependencies) and document it consistently, or remove the runtime dependency by not shipping icon-based defaults.

README.md documents npm run test:watch, but there is no test:watch script in package.json. Either add the script (e.g., vitest --watch) or update the README to match the available scripts.

Suggested change

	# Run tests in watch mode
	npm run test:watch

.npmignore references vitest.config.ts, but the repo uses vitest.config.mts. If you intend to exclude the Vitest config from published artifacts, update this entry to the correct filename (or remove it if files in package.json is the source of truth).

Suggested change

	vitest.config.ts
	vitest.config.mts

external: ['@heroicons/react'] will not externalize subpath imports like @heroicons/react/outline (used in defaultItems.tsx) with esbuild/tsup external matching. This can lead to unexpectedly bundling heroicons or build/runtime resolution differences. Use a pattern that matches subpaths (e.g. @heroicons/react/*) or list the specific subpath(s) you import.

[Copilot]

Exporting defaultAccordionItems that directly imports @heroicons/react/outline makes the library require Heroicons at runtime even when consumers pass their own items (module import still executes). Consider moving these defaults to examples/ (or a separate optional entry point) or making defaults icon-agnostic so the core package doesn't hard-depend on Heroicons.
