## Overview

1. **What this repo is**
   - `react-weui` is a **React component library** that wraps the WeUI design system.
   - There is **no backend or server-side business domain** here; the architecture is centered on **reusable UI components, styling, docs, examples, and tests**.

2. **Public library boundary**
   - The main package entry is `src/index.js`.
   - That file re-exports the component surface area from `src/components/**`, so consumers import from the package root rather than internal files.
   - `src/version.js` holds package version metadata used by the build/runtime surface.

3. **Component subsystem structure**
   - The library is organized by component family under `src/components/`.
   - Each component typically has:
     - a main React component file,
     - an `index.js` barrel export,
     - and sometimes a `.less` stylesheet.
   - The structure is intentionally granular: many components are split into small internal pieces such as `button_area`, `button_preview`, `panel_header`, `tabbar_item`, `mediabox_info_meta`, etc.

4. **Design of the UI layer**
   - Components are mostly **presentational React components** that compose smaller building blocks into WeUI patterns.
   - Examples of composite areas include:
     - `form/` for inputs, toggles, uploader, validation-related controls,
     - `cell/`, `panel/`, and `mediabox/` for grouped list/content layouts,
     - `tab/` and `swiper/` for navigation and page switching patterns,
     - `popup/`, `dialog/`, `toast/`, `toptips/`, and `mask/` for overlays and notifications.

5. **Styling and asset boundary**
   - Styling is split between:
     - package-local styles in `src/components/**.less`,
     - and external base styles from **WeUI** itself.
   - The README’s example explicitly imports both `weui` and `react-weui` CSS, which means the library depends on the external WeUI stylesheet as part of its rendering contract.
   - The build outputs a distributable CSS bundle referenced as `build/packages/react-weui.css`.

6. **Utilities and shared behavior**
   - `src/utils/` contains cross-cutting helpers such as:
     - `classnames.js` for class name composition,
     - `deprecationWarning.js` for runtime warnings around legacy APIs.
   - These utilities support consistency across component implementations rather than introducing a separate domain layer.

7. **Docs site subsystem**
   - The `docs/` directory is a separate **documentation application** built from React components and markdown content.
   - It includes:
     - page containers in `docs/pages/`,
     - UI chrome in `docs/components/`,
     - guide content in `docs/guide/`,
     - generated metadata like `docs/docs.json` and `docs/langs.json`.
   - This site powers the live documentation and component previews, so it is a consumer of the library rather than part of the library runtime.

8. **Example application subsystem**
   - The `example/` directory is a second consumer app that demonstrates real usage patterns.
   - It contains many page-level demos for specific components such as button, dialog, picker, tab, toast, uploader, etc.
   - This folder is useful for understanding the integration boundary: it shows how the exported components are composed into app screens.

9. **Testing strategy**
   - `test/` contains per-component unit tests that largely mirror the `src/components/` tree.
   - The test suite includes shared setup (`test/setup.js`) and Mocha config (`test/mocha.opts`).
   - This indicates the primary validation strategy is **component-level rendering/behavior testing**, not end-to-end system testing.

10. **Build and packaging pipeline**
   - `webpack.config.js` builds the library package, while `webpack.config.doc.js` builds the documentation app.
   - `scripts/build.js` is the build orchestration entry.
   - Babel, ESLint, and the webpack configs define the compile boundary from source React/JS/LESS into distributable assets.
   - The repo is packaged for npm, with CI/publish automation in `.github/workflows/`, plus legacy Travis config.

11. **External dependencies and runtime assumptions**
   - The runtime assumes a **browser React environment** with `react` and `react-dom`.
   - The library is paired with the external `weui` package for visual styling and theme alignment.
   - Distribution is designed for both npm installation and CDN consumption, which is why the build artifacts are important public outputs.

12. **How to think about the architecture diagram**
   - Draw the repo as three main consumers of the same component source:
     - the **library package** (`src/` → built npm/CSS artifacts),
     - the **documentation site** (`docs/`),
     - and the **example app** (`example/`).
   - Put `src/components/**` at the center, with `src/index.js` as the public API boundary.
   - Add a side layer for shared utilities and styling, and a separate validation layer for tests.
