totes

类似 React 的 Web 组件。 由 lit-html 提供支持。

支持：

• [x] setState
• [x] render
• [x] componentDidMount
• [x] shouldComponentUpdate
• [x] getSnapshotBeforeUpdate
• [x] component[Did]Unmount
• [x] componentDidUpdate
• [x] getDerivedStateFromProps
• [x] this.props.children

Quick start (copy and paste)

<script type="module">
  import { html, Component } from "https://unpkg.com/@aaronshaf/totes@1/index.js";

  class HelloWorld extends Component {
    render() {
      return html`<div>Hello, ${this.props.name}</div>`;
    }
  }

  customElements.define("hello-world", HelloWorld);
</script>

<hello-world name="Aaron"></hello-world>

就是这样。 没有构建步骤。️ ????

Example: setState and event handlers

export default class BasicExample extends Component {
  static get observedAttributes() {
    return ["message"];
  }

  constructor() {
    super();
    this.state = {
      name: "Aaron",
      toggled: false
    };
  }

  handleInput(event) {
    this.setState({ name: event.target.value || "Aaron" });
  }

  handleClick() {
    this.setState({ toggled: this.state.toggled === false });
  }

  render() {
    return html`<div>
      <div>
        <input
          type="text"
          value="Aaron"
          @input=${this.handleInput}
        />
      </div>

      <p>${this.props.message} ${this.state.name}</p>

      <button @click=${this.handleClick}>
        ${this.state.toggled ? "On" : "Off"}
      </button>
    </div>`;
  }
}

customElements.define("basic-example", BasicExample);

<basic-example message="Hello"></basic-example>
