An asynchronous JSX runtime without dependencies to be used as html template engine for server or browser.
This runtime was initially developed for Jeasx, but has a value of its own. Its main focus is to keep things simple, reliable and fast.
You can find more information about using this runtime as template engine in the Jeasx documentation.
npm i jsx-async-runtimeTo make use of the jsx-async-runtime, you need to configure your transpiler to utilize this package for transforming the JSX syntax.
If you are using TypeScript for transpiling your code base, simply set these options in your tsconfig.json:
{
"compilerOptions": {
"jsx": "react-jsx",
"jsxImportSource": "jsx-async-runtime"
}
}If you're using jsx-async-runtime as template engine, you might want to include data from an asynchronous operation in the resulting markup. To simplify this process, you can make your components asynchronous and send async requests from within them.
Please note: jsx-async-runtime doesn't escape html entities per default, so rendering user input makes your application vulnerable to cross site scripting. jsx-async-runtime exports a utility function called escapeEntities which can be used to render input from uncontrolled sources.
You can study the example project to learn about existing features.
import { escapeEntities, jsxToString } from "jsx-async-runtime";
export default function App() {
return (
<>
{`<!DOCTYPE html>`}
<html>
<head>
<meta charset="utf-8" />
<title>Todos</title>
</head>
<body>
<Header label="<Todos>" />
<TodoList quantity={3} />
</body>
</html>
</>
);
}
function Header({ label }) {
return (
<section
style={{
"background-color": "red",
"padding-bottom": "1rem",
}}
>
<h1 style="color: white; text-align: center">{escapeEntities(label)}</h1>
</section>
);
}
async function TodoList({ quantity }) {
const { todos } = await (await fetch("https://dummyjson.com/todos")).json();
return (
<table class="table">
<thead class={{ thead: true, striped: false, sticky: true }}>
<tr>
<th>Label</th>
<th>Status</th>
</tr>
</thead>
<tbody class="tbody striped">
{todos.slice(0, quantity).map(({ todo, completed }) => (
<tr>
<td>
<label for="todo">{escapeEntities(todo)}</label>
</td>
<td>
<label for="status">{completed ? "yes" : "no"}</label>
</td>
</tr>
))}
</tbody>
</table>
);
}
console.log(await jsxToString(<App />));
