React 中的 Font Awesome 图标

Question

使用字符串作为图标参数的值时，我无法使 Font Awesome 图标正常工作。

这项工作：

import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';
import { faCoffee } from '@fortawesome/free-solid-svg-icons'

 <FontAwesomeIcon icon={faCoffee} />

然而这不是：

import { FontAwesomeIcon } from '@fortawesome/react-fontawesome';

<FontAwesomeIcon icon="coffee" />

根据这个 documentation 它应该。但我是 React 的新手，所以可能会遗漏一些东西。

使用javascript。使用 react cli 创建的项目。

Package.json:

{
  "name": "test",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "@fortawesome/fontawesome-svg-core": "^1.2.34",
    "@fortawesome/free-brands-svg-icons": "^5.15.2",
    "@fortawesome/free-regular-svg-icons": "^5.15.2",
    "@fortawesome/free-solid-svg-icons": "^5.15.2",
    "@fortawesome/react-fontawesome": "^0.1.14",
    "@testing-library/jest-dom": "^5.11.9",
    "@testing-library/react": "^11.2.3",
    "@testing-library/user-event": "^12.6.2",
    "font-awesome": "^4.7.0",
    "node-sass": "^4.14.1",
    "react": "^17.0.1",
    "react-dom": "^17.0.1",
    "react-metismenu": "^1.4.0",
    "react-router-dom": "^5.2.0",
    "react-scripts": "4.0.1",
    "rsuite": "^4.8.8",
    "web-vitals": "^0.2.4"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  },
  "eslintConfig": {
    "extends": [
      "react-app",
      "react-app/jest"
    ]
  },
  "browserslist": {
    "production": [
      ">0.2%",
      "not dead",
      "not op_mini all"
    ],
    "development": [
      "last 1 chrome version",
      "last 1 firefox version",
      "last 1 safari version"
    ]
  }
}

我所说的“不工作”是指图标在页面上不可见并且控制台出现错误：“找不到图标 {prefix: “fas”, iconName: “coffee”}”

Answer 1

您需要像这样导入 library：import { library } from '@fortawesome/fontawesome-svg-core'

然后添加您要使用的图标。

import { faCoffee } from '@fortawesome/free-solid-svg-icons'

library.add(faCoffee /*, faCheckSquare, etc*/)

在此之后，您应该可以将图标用作“咖啡”了。如果您没有将图标添加到库中，它们将不会包含在捆绑包中，因此会出现错误。
