jsx-async-runtime v0.2.1
jsx-async-runtime
An asynchronous JSX runtime without dependencies to be used as html template engine.
Getting started
Installation
npm i jsx-async-runtimeBuilding
To 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, simply set these options in the tsconfig file:
{
"compilerOptions": {
"jsx": "react-jsx",
"jsxImportSource": "jsx-async-runtime"
}
}Using
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, renderToString } 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 renderToString(<App />));
