React TS - 如何映射 FontAwesome 图标并显示它们

Question

我正在尝试创建一个可重用的组件，它允许我传入href 、 target 、 rel属性以及我想使用的 FontAwesome 图标类型。 我希望能够将尽可能多的图标传递到这个列表中，它会使用社交组件作为模板来映射它们。

我希望地图发生在Social.tsx文件中，然后我可以简单地将组件添加到我的项目中的任何位置，然后将道具传递给它。

像这样的东西：

<Social
  icons={[
    { icon: "facebook", href: "", target: "", rel: "" },
    { icon: "twitter", href: "", target: "", rel: "" },
    { icon: "discord", href: "", target: "", rel: "" }
  ]}
/>

我目前有我的组件：

Social.tsx

import { FontAwesomeIcon } from "@fortawesome/react-fontawesome";
import * as React from "react";

interface ISocial {
  href?: string
  target?: string
  rel?: string
}

const Social: React.FC<ISocial> = (props) => {
  return (
    <div>
      <a href={props.href} target={props.target} rel={props.rel}>
        {/* I don't want to hardcode the icon, but dynamically pass it as a prop */}
        <FontAwesomeIcon icon={["fab", "discord"]} />
      </a>
    </div>
  );
};

export default Social;

应用程序.tsx

import * as React from "react";
import "./styles.css";
import Social from "./components/Social";

export default function App() {
  // I'd like to be able to pass in a list of different icons
  // followed by the href, target, rel, etc for each item.
  // The Social component would be able to map through them
  // and display them.
  return <Social />;

我怎样才能适应它来做我上面描述的事情？

所以，我认为问题在于构建你想要传递的道具。

例如，我们将传递一个IconProp类型的数组，然后您可以轻松地对其进行映射。

现在你可以制作自己的界面并传递这种类型的道具

interface myType {
  href?: string;
  target?: string;
  rel?: string;
  icon: IconProp;
}
const dummyProp: myType[] = [
  { icon: ["fab", "discord"] },
  { icon: ["fab", "discord"] },
  { icon: ["fab", "discord"] },
  { icon: ["fab", "discord"] }
];

const Social: React.FC<ISocial> = props => {
  return (
    <div>
      {dummyProp.map(p => (
        <a href={p.href} target={p.target} rel={p.rel}>
          <FontAwesomeIcon icon={p.icon} />
        </a>
      ))}
    </div>
  );

有一个带有图标名称的字符串列表，如果需要列表，请使用map 。

export default function App() {
  return (
    <Social
      icons={[
        { icon: "facebook", href: "", target: "", rel: "" },
        { icon: "twitter", href: "", target: "", rel: "" },
        { icon: "discord", href: "", target: "", rel: "" }
      ]}
    />
  );
}

社会成分的变化。 只需添加新的道具，如name

import { FontAwesomeIcon } from "@fortawesome/react-fontawesome";
import * as React from "react";
import { IconName } from "@fortawesome/fontawesome-svg-core";

interface ISocial {
  href?: string;
  target?: string;
  rel?: string;
  icon: IconName;
}

interface ISocialList {
  icons: Array<ISocial>;
}

const Social: React.FC<ISocialList> = props => {
  const { icons } = props;
  return (
    <div>
      {icons.map(item => {
        return (
          <a href={item.href} target={item.target} rel={item.rel}>
            <FontAwesomeIcon icon={["fab", item.icon]} />
          </a>
        );
      })}
    </div>
  );
};

export default Social;
