+# Stand-alone demo pages for sketch web components
+
+These are handy for iterating on specific component UI issues in isolation from the rest of the sketch application, and without having to start a full backend to serve the full frontend app UI.
+
+See [README](../../../readme.md#development-mode) for more information on how to run the demo pages.

Use the `@customElement` decorator to define the component\\n2. Encapsulate styles using the static `styles` property\\n3. Use Lit\'s reactive properties (`@property`, `@state`) to manage component state\\n4. Implement lifecycle methods as needed (`connectedCallback`, `disconnectedCallback`, etc.)\\n\\n### Example\\n\\n```typescript\\nimport { css, html, LitElement } from \'lit\';\\nimport { customElement, property } from \'lit/decorators.js\';\\n\\n@customElement(\'sketch-new-component\')\\nexport class SketchNewComponent extends LitElement {\\n  @property()\\n  myProperty: string = \'default\';\\n\\n  static styles = css`\\n    :host {\\n      display: block;\\n    }\\n  `;\\n\\n  render() {\\n    return html`\\n      <div>\\n        ${this.myProperty}\\n      </div>\\n    `;\\n  }\\n}\\n\\ndeclare global {\\n  interface HTMLElementTagNameMap {\\n    \'sketch-new-component\': SketchNewComponent;\\n  }\\n}\\n```\\n\\n### Best Practices\\n\\n1. Maintain a single responsibility for each component\\n2. Use properties and events for parent-child communication\\n3. Document the purpose and API of each component\\n4. Write tests for components where possible\\n5. Keep styles encapsulated within components\\n6. Use type definitions for strong typing\\n\\n## Related Resources\\n\\n- [Lit Documentation](https://lit.dev/docs/)\\n- [Web Components Introduction](https://developer.mozilla.org/en-US/docs/Web/Web_Components)\\n- See `/app/webui/readme.md` for more information on the Loop WebUI project\\n"}]}',

These components are built using the [Lit](https://lit.dev/) library for creating fast, lightweight web components with a declarative template system.\\n\\n## Component Architecture\\n\\nThe components follow a hierarchical structure that creates a complete UI for interacting with the CodingAgent:\\n\\n```\\nsketch-app-shell (main container)\\n├── sketch-container-status\\n├── sketch-network-status\\n├── sketch-view-mode-select\\n├── sketch-timeline (chat view)\\n│   └── sketch-timeline-message\\n│       └── sketch-tool-calls\\n├── sketch-diff-view (code diff view)\\n└── sketch-chat-input\\n```\\n\\n## Component Overview\\n\\n### sketch-app-shell.ts\\nThe main container component that orchestrates the entire UI. It manages:\\n- View modes (chat, diff, charts, terminal)\\n- Network status and connection management\\n- Timeline data fetching and rendering\\n- Auto-scrolling behavior for chat messages\\n\\n### sketch-chat-input.ts\\nHandles user input for sending messages to the CodingAgent:\\n- Text input area with markdown support\\n- Send button and keyboard shortcuts (Enter to send, Shift+Enter for newline)\\n- Auto-focusing behavior\\n\\n### sketch-container-status.ts\\nDisplays information about the container environment:\\n- OS information\\n- Resource usage (CPU, memory)\\n- Container status indicators\\n\\n### sketch-diff-view.ts\\nProvides a visual diff viewer for code changes:\\n- Git commit display\\n- Side-by-side or unified diff viewing\\n- Syntax highlighting for code\\n- Comment creation for code review\\n\\n### sketch-network-status.ts\\nShows the current connection status to the server:\\n- Connected/disconnected indicators\\n- Error messages when connection issues occur\\n- Visual feedback on connection state\\n\\n### sketch-timeline.ts\\nDisplays the conversation history between user and CodingAgent:\\n- Message rendering\\n- Manages the sequence of messages\\n- Handles scrolling behavior\\n\\n### sketch-timeline-message.ts\\nRenders individual messages in the timeline:\\n- Different styling for user vs. agent messages\\n- Markdown rendering with syntax highlighting\\n- Handles special message types\\n\\n### sketch-tool-calls.ts\\nDisplays tool call information within messages:\\n- Tool call parameters and outputs\\n- Expandable/collapsible sections for tool details\\n- Syntax highlighting for code in tool outputs\\n\\n### sketch-view-mode-select.ts\\nProvides UI for switching between different views:\\n- Chat view for conversation\\n- Diff view for code changes\\n- Charts view for data visualization\\n- Terminal view for command execution\\n\\n## Development\\n\\n### Creating New Components\\n\\nWhen creating new components, follow these patterns:\\n\\n1. Use the `@customElement` decorator to define the component\\n2. Encapsulate styles using the static `styles` property\\n3. Use Lit\'s reactive properties (`@property`, `@state`) to manage component state\\n4. Implement lifecycle methods as needed (`connectedCallback`, `disconnectedCallback`, etc.)\\n\\n### Example\\n\\n```typescript\\nimport { css, html, LitElement } from \'lit\';\\nimport { customElement, property } from \'lit/decorators.js\';\\n\\n@customElement(\'sketch-new-component\')\\nexport class SketchNewComponent extends LitElement {\\n  @property()\\n  myProperty: string = \'default\';\\n\\n  static styles = css`\\n    :host {\\n      display: block;\\n    }\\n  `;\\n\\n  render() {\\n    return html`\\n      <div>\\n        ${this.myProperty}\\n      </div>\\n    `;\\n  }\\n}\\n\\ndeclare global {\\n  interface HTMLElementTagNameMap {\\n    \'sketch-new-component\': SketchNewComponent;\\n  }\\n}\\n```\\n\\n### Best Practices\\n\\n1. Maintain a single responsibility for each component\\n2. Use properties and events for parent-child communication\\n3. Document the purpose and API of each component\\n4. Write tests for components where possible\\n5. Keep styles encapsulated within components\\n6. Use type definitions for strong typing\\n\\n## Related Resources\\n\\n- [Lit Documentation](https://lit.dev/docs/)\\n- [Web Components Introduction](https://developer.mozilla.org/en-US/docs/Web/Web_Components)\\n- See `/app/webui/readme.md` for more information on the Loop WebUI project\\n"}]}',

Use the `@customElement` decorator to define the component\\n2. Encapsulate styles using the static `styles` property\\n3. Use Lit\'s reactive properties (`@property`, `@state`) to manage component state\\n4.

Maintain a single responsibility for each component\\n2. Use properties and events for parent-child communication\\n3. Document the purpose and API of each component\\n4. Write tests for components where possible\\n5. Keep styles encapsulated within components\\n6.
