AppRun is a lightweight alternative to other frameworks and libraries. It has a unique architecture inspired by the Elm architecture that can help you manage states, routing, and other essential aspects of your web application.
Use a Counter as an example.
// define the initial state
const state = 0;
// view is a function to display the state (JSX)
const view = state => <div>
<h1>{state}</h1>
<button onclick="app.run('-1')">-1</button>
<button onclick="app.run('+1')">+1</button>
</div>;
// update is a collection of event handlers
const update = {
'+1': state => state + 1,
'-1': state => state - 1
};
// start the app
app.start(document.body, state, view, update);-
AppRun is lightweight, only 6KB gzipped, but includes state management, rendering, event handling, and routing.
-
With only three functions:
app.start,app.run, andapp.onin its API makes it easy to learn and use. And no worries about the incompatibility of version upgrades. -
One more thing, you can use AppRun with React to simplify state management and routing of your React applications.
At its core, AppRun harnesses the power of the event PubsSub pattern to streamline your application’s state handling and routing. The result? Cleaner, more maintainable code and a smoother development experience.
- Clean architecture that needs less code
- State management and routing included
- No proprietary syntax to learn (no hooks, no reducers, no signals)
- Use directly in the browser or with a compiler/bundler
- Advanced features: JSX, Web Components, Dev Tools, SSR, etc.
AppRun is distributed on npm. To get it, run:
npm install apprunYou can also load AppRun directly from the unpkg.com CDN:
<html>
<body>
<script src="https://unpkg.com/apprun/dist/apprun-html.js"></script>
<script>
const view = state => `<div>${state}</div>`;
app.start(document.body, 'hello AppRun', view);
</script>
</body>
</html>Or, use the ESM version:
<html>
<body>
<script type="module">
import { app, html } from 'https://unpkg.com/apprun/dist/apprun-html.esm.js';
const view = state => html`<div>${state}</div>`;
app.start(document.body, 'hello ESM', view);
</script>
</body>
</html>In addition to run directly in the browser, or with a compiler/bundler like Webpack or Vite.
You can run the npm create apprun-app command to create an AppRun project.
npm create apprun-app [my-app]You can get started with AppRun Docs and the AppRun Playground.
You can launch the webpack dev-server and the demo app from the demo folder with the following npm commands:
npm install
npm startYou can run the unit tests from the tests folder.
npm testUnit tests can serve as functional specifications.
Finally, to build optimized js files to the dist folder, just run:
npm run buildHave fun and send pull requests.
