## Overview
Satori supports the JSX syntax, which makes it very straightforward to use. Here’s an overview of the basic usage:
```jsx
// api.jsx
import satori from 'satori'
const svg = await satori(
hello, world
,
{
width: 600,
height: 400,
fonts: [
{
name: 'Roboto',
// Use `fs` (Node.js only) or `fetch` to read the font as Buffer/ArrayBuffer and provide `data` here.
data: robotoArrayBuffer,
weight: 400,
style: 'normal',
},
],
},
)
```
Satori will render the element into a 600×400 SVG, and return the SVG string:
```js
''
```
Under the hood, it handles layout calculation, font, typography and more, to generate a SVG that matches the exact same HTML and CSS in a browser.
## Documentation
### JSX
Satori only accepts JSX elements that are pure and stateless. You can use a subset of HTML
elements (see section below), or custom React components, but React APIs such as `useState`, `useEffect`, `dangerouslySetInnerHTML` are not supported.
#### Use without JSX
If you don't have JSX transpiler enabled, you can simply pass [React-elements-like objects](https://reactjs.org/docs/introducing-jsx.html) that have `type`, `props.children` and `props.style` (and other properties too) directly:
```js
await satori(
{
type: 'div',
props: {
children: 'hello, world',
style: { color: 'black' },
},
},
options
)
```
### HTML Elements
Satori supports a limited subset of HTML and CSS features, due to its special use cases. In general, only these static and visible elements and properties that are implemented.
For example, the `` HTML element, the `cursor` CSS property are not in consideration. And you can't use `
