# @design.estate/dees-domtools

Browser-side TypeScript utilities for bootstrapping DOM work, responsive styling, theme handling, scrolling, metadata setup, and Lit-based web components.

It gives you a singleton-style `DomTools` runtime plus a few focused exports for CSS breakpoints, base element styling, and low-level integrations with the underlying `design.estate` and `push.rocks` packages.

## Installation

```bash
pnpm add @design.estate/dees-domtools
```

## What It Includes

- `DomTools` for one-time app bootstrap and shared browser services
- `breakpoints` helpers for viewport and container-query driven Lit CSS
- `css.cssGridColumns()` for simple grid-template generation
- `elementBasic` helpers for Lit base styles and one-time global CSS setup
- `TypedRequest` re-exported from `@api.global/typedrequest`
- `plugins` for direct access to the package ecosystem used internally

The `plugins` export keeps the commonly used downstream namespaces available, including `plugins.smartdelay`, `plugins.smartstate`, `plugins.smartpromise`, `plugins.smartrouter`, `plugins.smartrx`, `plugins.smarturl`, and `plugins.typedrequest`.

## Quick Start

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools();
await domtools.domReady.promise;

console.log(domtools.elements.headElement);
console.log(domtools.elements.bodyElement);
```

`setupDomTools()` is safe to call repeatedly. By default it returns a shared global instance and avoids duplicate initialization work.

If you need an isolated instance for testing or short-lived usage, pass `ignoreGlobal: true`. Isolated instances follow the same `domToolsReady` and `domReady` lifecycle as the shared singleton.

## DomTools Lifecycle

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools({
  ignoreGlobal: false,
});

await domtools.domToolsReady.promise;
await domtools.domReady.promise;
```

`setupDomTools()` resolves once the instance is initialized and its readiness listeners are installed. `domReady` resolves later, once `document.head` and `document.body` are available.

Main instance properties:

- `elements.headElement` and `elements.bodyElement`
- `router` from `@push.rocks/smartrouter`
- `websetup` from `@push.rocks/websetup`
- `smartstate` and `domToolsStatePart`
- `themeManager`
- `scroller`
- `keyboard` after `domReady`
- `deesComms`
- `convenience.typedrequest`, `convenience.smartdelay`, `convenience.smartjson`, `convenience.smarturl`

If you need the already-created global instance synchronously, use `DomTools.getGlobalDomToolsSync()` after startup has completed.

## Cleanup

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools({
  ignoreGlobal: true,
});

// ...use the instance

domtools.dispose();
```

`dispose()` removes the listeners and DOM resources owned by that `DomTools` instance. For shared global usage you usually keep the singleton alive for the lifetime of the page, but disposal is useful for tests and intentionally short-lived isolated instances.

## DOM, CSS, and External Resources

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools();

await domtools.setGlobalStyles(`
  body {
    margin: 0;
    font-family: Inter, sans-serif;
  }
`);

await domtools.setExternalCss(
  'https://fonts.googleapis.com/css2?family=Inter:wght@400;600;700&display=swap'
);

await domtools.setExternalScript('https://cdn.example.com/some-script.js');
```

For page metadata and favicons:

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools();

await domtools.setWebsiteInfo({
  metaObject: {
    title: 'Example App',
    description: 'A browser app bootstrapped with DomTools',
  },
  faviconUrl: '/favicon.ico',
});
```

## Theme Management

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools();
const { themeManager } = domtools;

themeManager.themeObservable.subscribe((isBright) => {
  console.log('bright mode?', isBright);
});

themeManager.goDark();
themeManager.goBright();
themeManager.toggleDarkBright();

await themeManager.enableAutomaticGlobalThemeChange();
```

The theme manager starts from `prefers-color-scheme` and publishes updates through an RxJS `ReplaySubject<boolean>`.

`enableAutomaticGlobalThemeChange()` waits for `domReady`, so it is safe to call before `document.body` exists.

## Keyboard Shortcuts

The keyboard helper is created after `document.body` exists, so wait for `domReady` before using it.

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools();
await domtools.domReady.promise;

const keyboard = domtools.keyboard!;
const { keyEnum } = keyboard;

keyboard.on([keyEnum.Ctrl, keyEnum.S]).subscribe(() => {
  console.log('save triggered');
});

keyboard.triggerKeyPress([keyEnum.Ctrl, keyEnum.S]);
```

## Scrolling

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools();
const { scroller } = domtools;

scroller.onScroll(() => {
  console.log('scroll event');
});

await scroller.enableLenisScroll({
  disableOnNativeSmoothScroll: true,
});

const section = document.querySelector('#details') as HTMLElement;
await scroller.toElement(section, { duration: 600 });
```

The scroller uses native scroll listeners by default and switches to Lenis when enabled.

## Responsive CSS Helpers

`breakpoints` is designed for Lit CSS and ships both preset breakpoints and lower-level helpers.

```ts
import { breakpoints } from '@design.estate/dees-domtools';
import { css } from 'lit';

const styles = css`
  :host {
    display: block;
    padding: 24px;
  }

  ${breakpoints.cssForTablet(css`
    :host {
      padding: 16px;
    }
  `)}

  ${breakpoints.cssForPhone(css`
    :host {
      padding: 10px;
    }
  `)}
`;
```

Available values:

- `breakpoints.desktop` => `1600`
- `breakpoints.notebook` => `1240`
- `breakpoints.tablet` => `1024`
- `breakpoints.phablet` => `600`
- `breakpoints.phone` => `400`

Available helpers:

- `cssForDesktop()`
- `cssForNotebook()`
- `cssForTablet()`
- `cssForPhablet()`
- `cssForPhone()`
- `cssForViewport()`
- `cssForContainer()`
- `cssForConstraint()`
- `cssForConstraintContainer()`
- `containerContextStyles()`

Viewport helpers emit both `@media` and `@container wccToolsViewport` rules. Container helpers target a named CSS container only.

## CSS Utility

```ts
import { css } from '@design.estate/dees-domtools';

const columns = css.cssGridColumns(3, 24);

console.log(columns);
```

This returns a ready-to-insert `grid-template-columns` string.

## Lit Element Setup

```ts
import { elementBasic } from '@design.estate/dees-domtools';
import { LitElement, html } from 'lit';

class DemoElement extends LitElement {
  static styles = [elementBasic.staticStyles];

  async connectedCallback() {
    super.connectedCallback();
    await elementBasic.setup(this);
  }

  render() {
    return html`<p>Hello DOM tools</p>`;
  }
}
```

`elementBasic.setup()` performs the shared `DomTools` setup and injects the package's global base styles once.

The returned promise resolves after the shared base styles have been injected, and `domtools.globalStylesReady` resolves at the same point.

## State and One-Time Work

`domToolsStatePart` starts with this shape:

```ts
{
  virtualViewport: 'native',
  jwt: '',
}
```

You can also guard expensive async work with `runOnce()`:

```ts
import { DomTools } from '@design.estate/dees-domtools';

const domtools = await DomTools.setupDomTools();

const result = await domtools.runOnce('load-config', async () => {
  return { ok: true };
});
```

Repeated callers receive the first result, and repeated failures re-throw the stored error.

## Extra Exports

```ts
import { TypedRequest, plugins } from '@design.estate/dees-domtools';
```

- `TypedRequest` is re-exported for typed request flows
- `plugins` exposes the underlying modules used by the package, including `smartrouter`, `smartstate`, `smartrx`, `smartpromise`, `typedrequest`, and `deesComms`

## Runtime Notes

- This package is browser-oriented and touches `window`, `document`, `navigator`, and `matchMedia`
- `keyboard` is `null` until `domReady` resolves
- The published package targets the latest Chrome via `browserslist`
