knexer-jsx
A tiny (1.8kb gzipped) React-like library that supports function components and hooks.
Usage
We'll show the usage of knexer-jsx by using a simple javascript app. The app shows the number of times a button has been clicked.
First, create an empty javascript app and add knexer-jsx as a dependency:
mkdir knexer-jsx-example && cd $_
npm init -y
npm i knexer-jsxNext, create a javascript file:
mkdir src
touch src/main.jsxPaste the following code into src/main.jsx:
/** @jsx h */
import { h, mount, useState } from "knexer-jsx";
function Counter() {
const [count, setCount] = useState(0);
return (
<div>
<span>{count}</span>
<button onClick={() => setCount(count + 1)}>Click</button>
</div>
);
}
mount(document.getElementById('root'), <Counter/>);Lastly, bundle the app into a standalone javascript file. This requires a few development dependencies and config files for babel and webpack.
- Install webpack and babel
npm i -D webpack webpack-cli @babel/core babel-loader @babel/preset-env @babel/plugin-transform-react-jsx- Create a file called
babel.config.jsonwith the following content:
{
"plugins": ["@babel/plugin-transform-react-jsx"],
"presets": ["@babel/preset-env"]
}- Create a file called
webpack.config.jswith the following content:
const path = require("path");
module.exports = {
entry: "./src/main.jsx",
module: {
rules: [
{
test: /\.jsx?$/,
use: "babel-loader",
exclude: /node_modules/,
},
],
},
resolve: {
extensions: [".jsx", ".js"],
},
output: {
filename: "bundle.js",
path: path.resolve(__dirname, "dist"),
},
};
- Finally, add a new script entry in the
package.json:
"scripts": {
"build": "webpack --mode development"
}That's it!
Now we can bundle our app into a standalone file with the following command:
npm run buildYou can test the new app with an html file like below:
<!doctype html>
<html>
<body>
<div id="root"></div>
<script src="./dist/bundle.js"></script>
</body>
</html>The source code of the final app can be found here.
