HyperApp是用于构建前端应用程序的JavaScript库。

  • 声明式：HyperApp的设计基于Elm Architecture。 使用功能范例创建可扩展的基于浏览器的应用程序。 关键是你不必学习一种新的语言。
  • 无状态组件：使用纯函数构建复杂的用户界面。 无状态组件是框架无关的、可预测的、容易调试的。
  • 包含：开箱即用，HyperApp将状态管理与支持键控更新和生命周期事件的虚拟DOM引擎结合在一起，所有这些都不具有依赖关系。

Hyperapp npm

The tiny framework for building web interfaces.

  • Do more with less—We have minimized the concepts you need to learn to be productive. Views, actions, effects, and subscriptions are all pretty easy to get to grips with and work together seamlessly.
  • Write what, not how—With a declarative syntax that's easy to read and natural to write, Hyperapp is your tool of choice to develop purely functional, feature-rich, browser-based applications.
  • Hypercharged—Hyperapp is a modern VDOM engine, state management solution, and application design pattern all-in-one. Once you learn to use it, there'll be no end to what you can do.

To learn more, go to https://hyperapp.dev for documentation, guides, and examples.

Quickstart

Install Hyperapp with npm or Yarn:

npm i hyperapp

Then with a module bundler like Parcel or Webpack import it in your application and get right down to business.

import { h, app } from "hyperapp"

Don't want to set up a build step? Import Hyperapp in a <script> tag as a module. Don't worry; modules are supported in all evergreen, self-updating desktop, and mobile browsers.

<script type="module">
  import { h, app } from "https://unpkg.com/hyperapp"
</script>

Here's the first example to get you started: a counter that can go up or down. You can try it online here.

<!DOCTYPE html>
<html lang="en">
  <head>
    <script type="module">
      import { h, app } from "https://unpkg.com/hyperapp"

      app({
        init: 0,
        view: state =>
          h("main", {}, [
            h("h1", {}, state),
            h("button", { onClick: state => state - 1 }, "-"),
            h("button", { onClick: state => state + 1 }, "+")
          ]),
        node: document.getElementById("app")
      })
    </script>
  </head>
  <body>
    <main id="app"></main>
  </body>
</html>

The app starts off with init as the initial state. Our code doesn't explicitly maintain any state. Instead, we define actions to transform it and a view to visualize it. The view returns a plain object representation of the DOM known as a virtual DOM, and Hyperapp updates the real DOM to match it whenever the state changes.

Now it's your turn! Experiment with the code a bit. Spend some time thinking about how the view reacts to changes in the state. Can you add a button that resets the counter back to zero? Or how about multiple counters?

Help, I'm stuck!

We love to talk JavaScript and Hyperapp. If you've hit a stumbling block, hop on the Hyperapp Slack or drop by Spectrum to get support, and if you don't receive an answer, or if you remain stuck, please file an issue, and we'll try to help you out.
