# zerolith/jsx-runtime

Import from `zerolith/jsx-runtime`. Generated from the source; every signature below is what the published types declare.

## Functions

### jsx

```ts
function jsx(): never
```

Reached only when JSX was not lowered; throws a diagnostic.

Source: `packages/zerolith/src/jsx-runtime.ts:43`

### jsxs

```ts
function jsxs(): never
```

The same as `jsx`.

Source: `packages/zerolith/src/jsx-runtime.ts:49`

### jsxDEV

```ts
function jsxDEV(): never
```

The same as `jsx`.

Source: `packages/zerolith/src/jsx-runtime.ts:52`

## Types

### ElementAttributes

```ts
type ElementAttributes = { readonly children?: unknown; readonly ref?: unknown; readonly [attribute: string]: unknown; readonly [property: `prop:${string}`]: unknown; readonly [event: `on:${string}`]: unknown; readonly [flag: `bool:${string}`]: unknown }
```

Attribute names an element accepts: plain attributes, and the `prop:`, `on:`, `bool:`, and `attr:` namespaces that select the other binding forms.

Source: `packages/zerolith/src/jsx-runtime.ts:11`

## Constants

### Fragment

```ts
const Fragment: unique symbol
```

Fragments lower to a template with no root element; the marker exists only for the types.

Source: `packages/zerolith/src/jsx-runtime.ts:40`

## Namespaces

### JSX

```ts
namespace JSX
```

The JSX namespace TypeScript reads.

- `type Element = View`: The type TypeScript gives every JSX expression and checks a function component's return type against: a `View`, which the lowered `html` call returns.
- `interface ElementChildrenAttribute { children: unknown }`: Names the prop that carries children; TypeScript reads only the property's name, `children`, and checks the content between an element's tags against that prop.
- `interface IntrinsicAttributes { ref?: unknown }`: Props TypeScript accepts on every component element on top of the component's own: `ref`, which the lowering passes to the component as an ordinary prop.
- `type IntrinsicElements = { readonly [tag in keyof HTMLElementTagNameMap]: ElementAttributes } & { readonly [tag: string]: ElementAttributes }`: Maps each intrinsic tag, a name such as `div` or `my-card`, to the attributes TypeScript checks on it: `ElementAttributes` for every tag.
