# @form-eng/base-web

Base Web (Uber) field components for [@form-eng/core](https://www.npmjs.com/package/@form-eng/core).

This package provides 28 field types using **Base Web (baseui)** components. Includes 10 native baseui components and 18 semantic HTML fallbacks. All fields integrate with `@form-eng/core`'s rules engine and form orchestration.

## Installation

```bash
npm install @form-eng/base-web @form-eng/core baseui styletron-engine-monolithic styletron-react react react-dom react-hook-form
```

## Quick Start

```tsx
import { FormEngine, RulesEngineProvider, InjectedFieldProvider } from "@form-eng/core";
import { createBaseWebFieldRegistry } from "@form-eng/base-web";
import { Client as Styletron } from "styletron-engine-monolithic";
import { Provider as StyletronProvider } from "styletron-react";
import { LightTheme, BaseProvider } from "baseui";

const engine = new Styletron();
const fields = createBaseWebFieldRegistry();

function App() {
  return (
    <StyletronProvider value={engine}>
      <BaseProvider theme={LightTheme}>
        <RulesEngineProvider>
          <InjectedFieldProvider fields={fields}>
            <FormEngine
              formConfig={myFormConfig}
              entityData={myEntityData}
              onSave={handleSave}
            />
          </InjectedFieldProvider>
        </RulesEngineProvider>
      </BaseProvider>
    </StyletronProvider>
  );
}
```

## Styling

Base Web components are styled via Styletron. You must wrap your application in a `StyletronProvider` and optionally a `BaseProvider` for theming. See [Base Web documentation](https://baseweb.design/) for theming details.

## Custom Fields

You can extend or replace any field in the registry:

```tsx
import { createBaseWebFieldRegistry } from "@form-eng/base-web";

const fields = createBaseWebFieldRegistry();

// Replace the textbox with your own component
fields["Textbox"] = <MyCustomTextbox />;

// Add a brand new field type
fields["PhoneNumber"] = <MyPhoneInput />;
```
