East UI

name: east-ui description: UI component definitions for the East language. Use when building UIs with @elaraai/east-ui. Triggers for: (1) Creating UI components with Stack, Box, Grid, Card, Text, Button, (2) Building forms with Input, Select, Checkbox, Switch, Slider, (3) Displaying data with Table, DataList, Chart, Badge, Tag, Stat, (4) Using overlays like Dialog, Drawer, Popover, Tooltip, Menu, (5) Working with UIComponentType, (6) Styling with variants (FontWeight, TextAlign, ColorScheme, Size).

East UI

UI component definitions for the East language. Components return data structures describing UI layouts rather than rendering directly, enabling portability across different rendering environments.

Quick Start

import { East, ArrayType } from "@elaraai/east";
import { Stack, Text, Button, UIComponentType } from "@elaraai/east-ui";

// Define a UI component
const MyComponent = East.function(
    [],
    UIComponentType,
    $ => {
        return Stack.Root([
            Text.Root("Hello, World!", { fontSize: "xl", fontWeight: "bold" }),
            Button.Root("Click Me", { variant: "solid", colorPalette: "blue" }),
        ], { gap: "4", direction: "column" });
    }
);

// Convert to IR for serialization or rendering
const ir = MyComponent.toIR();

Component Pattern

All components follow a consistent namespace pattern:

import { Badge, Stack, Button } from "@elaraai/east-ui";

// Create component using .Root()
const badge = Badge.Root("New", { variant: "solid", colorPalette: "green" });

// Compound components have sub-factories
const stack = Stack.Root([
    Text.Root("Item 1"),
    Text.Root("Item 2"),
], { gap: "4" });

// Access East types via .Types
const badgeType = Badge.Types.Badge;
const styleType = Badge.Types.Style;

Styling

Components accept style options with Chakra UI tokens:

Button.Root("Click", {
    variant: "solid",        // solid, outline, subtle, ghost
    colorPalette: "blue",    // gray, red, orange, yellow, green, teal, blue, purple, pink
    size: "md",              // xs, sm, md, lg
});

Text.Root("Hello", {
    fontSize: "xl",
    fontWeight: "bold",      // normal, medium, semibold, bold
    color: "gray.600",
});

Stack.Root([...], {
    gap: "4",                // Chakra spacing tokens
    direction: "row",        // row, column
    align: "center",         // flex alignment
});
