我正在使用创建-反应-应用程序,不喜欢弹出。

不清楚通过@font-face导入并在本地加载的字体应该放在哪里。

也就是说,我在装载

@font-face {
  font-family: 'Myriad Pro Regular';
  font-style: normal;
  font-weight: normal;
  src: local('Myriad Pro Regular'), url('MYRIADPRO-REGULAR.woff') format('woff');
}

有什么建议吗?

去谷歌字体https://fonts.google.com/ 选择如下图所示的字体:

复制并粘贴该url在新选项卡,你会得到css代码添加该字体。在这种情况下,如果你去

https://fonts.googleapis.com/css?family=Spicy+Rice

它会像这样打开:

4、复制并粘贴到你的style.css中,然后像这样简单地开始使用那种字体:

      <Typography
          variant="h1"
          gutterBottom
          style={{ fontFamily: "Spicy Rice", color: "pink" }}
        >
          React Rock
        </Typography>

其他回答

我的感觉是,如果你在你的网站上有本地的字体,你应该能够使用CSS字体加载API在运行时为你做字体加载,而不使用CSS文件。这是我写的一个React组件。它是基于上面user-rebo的答案,但尝试在使用后卸载字体。它似乎可以在火狐和Chrome浏览器中运行。代码是:

import React, { useEffect, PropsWithChildren, useRef } from "react";

type FontFaceFormat =
  | "woff"
  | "woff2"
  | "truetype"
  | "opentype"
  | "embedded-opentype"
  | "svg";

type FontWrapperProps = {
  fontName: string;
  fontURL: string;
  fontFormat?: FontFaceFormat;
};

/*
 * The FontWrapper class. Takes a fontName (like "Andika"), a fontURL (which
 * should go to the website's public folder), and an optional font type. Usage
 * should be as simple as:
 *
 * <FontWrapper fontName="Andika" fontURL="/fonts/Andika-Regular.ttf.woff2">
 *   <p>This is some text</p>
 * </FontWrapper>
 *
 * Note: document.fonts is of type FontFaceSet, which should include the add() and
 * delete() methods. However, the TypeScript libraries for Visual Studio Code
 * miss these. That's why I have two instances of "document.fonts as any" -
 * to make those red lines go away.
 */

export default function FontWrapper({
  fontName,
  fontURL,
  fontFormat = "woff2",
  children,
}: PropsWithChildren<FontWrapperProps>) {
  const fontRef = useRef(null);

  useEffect(() => {
    const loadFont = async () => {
      const font = new FontFace(
        fontName,
        `url(${fontURL}) format("${fontFormat}")`,
        {}
      );
      const fontResult = await font.load();
      fontRef.current = fontResult;
      await (document.fonts as any).add(font);
    };

    const unloadFont = async () => {
      await (document.fonts as any).delete(fontRef.current);
    };

    loadFont();

    return () => {
      unloadFont();
    };
  }, []);

  return <div style={{ fontFamily: fontName }}>{children}</div>;
}


用法是:

<FontWrapper fontName="Andika" fontURL="/fonts/Andika-Regular.ttf.woff2">
  <p>This is some text</p>
</FontWrapper>

有两种选择:

使用进口

这是建议的选项。它确保您的字体通过构建管道,在编译期间获得哈希值,以便浏览器缓存正确工作,并且如果文件丢失,您将得到编译错误。

正如在“添加图像,字体和文件”中所描述的,你需要从JS中导入一个CSS文件。例如,src/index.js默认导入src/index.css:

import './index.css';

这样的CSS文件通过构建管道,可以引用字体和图像。例如,如果你把一个字体放在src/fonts/MyFont。Woff,你的index.css可能包括这个:

@font-face {
  font-family: 'MyFont';
  src: local('MyFont'), url(./fonts/MyFont.woff) format('woff');
  /* other formats include: 'woff2', 'truetype, 'opentype',
                            'embedded-opentype', and 'svg' */
}

注意我们是如何使用以./开头的相对路径的。这是一种特殊的符号,可以帮助构建管道(由Webpack提供支持)发现该文件。

通常这就足够了。

使用公用文件夹

如果出于某种原因,你不喜欢使用构建管道,而是使用“经典的方式”,你可以使用公共文件夹并将字体放在那里。

这种方法的缺点是,在编译用于生产时,文件不会得到哈希值,因此每次更改它们时都必须更新它们的名称,否则浏览器将缓存旧版本。

如果你想这样做,把字体放在公共文件夹的某个地方,例如,在public/fonts/MyFont.woff。如果你遵循这种方法,你也应该把CSS文件放到公共文件夹中,而不是从JS中导入它们,因为混合这些方法会非常混乱。如果你还想这样做,你会有public/index。css这样的文件。你必须手动添加<link>到这个样式表从public/index.html:

<link rel="stylesheet" href="%PUBLIC_URL%/index.css">

在里面,你会使用常规的CSS符号:

@font-face {
  font-family: 'MyFont';
  src: local('MyFont'), url(fonts/MyFont.woff) format('woff');
}

Notice how I’m using fonts/MyFont.woff as the path. This is because index.css is in the public folder so it will be served from the public path (usually it’s the server root, but if you deploy to GitHub Pages and set your homepage field to http://myuser.github.io/myproject, it will be served from /myproject). However fonts are also in the public folder, so they will be served from fonts relatively (either http://mywebsite.example/fonts or http://myuser.github.io/myproject/fonts). Therefore we use the relative path.

注意,由于我们在本例中避免了构建管道,因此它不会验证文件是否实际存在。这就是我不推荐这种方法的原因。另一个问题是index.css文件没有被缩小,也没有得到哈希值。因此,对于最终用户来说,速度会变慢,而且浏览器可能会缓存旧版本的文件。

使用哪种方式?

使用第一个方法(“使用导入”)。我只描述了第二个,因为这是你试图做的(从你的评论来看),但它有很多问题,应该是你在解决某些问题时的最后手段。

你可以使用WebFont模块,它极大地简化了这个过程。

render(){
  webfont.load({
     custom: {
       families: ['MyFont'],
       urls: ['/fonts/MyFont.woff']
     }
  });
  return (
    <div style={your style} >
      your text!
    </div>
  );
}

我添加了

@font-face {
    font-family: 'Sanchez-Regular';
    src: local('Sanchez-Regular'),url(../assets/fonts/Sanchez/Sanchez-Regular.ttf) format('truetype');
}

而且效果非常好 就像我们在index.css中使用其他字体一样

我花了整个上午的时间来解决这个堆栈问题。我在上面的答案中使用了Dan的第一个解决方案作为出发点。

问题

我有一个开发(在我的本地机器上)、登台和生产环境。我的登台和生产环境位于同一台服务器上。

应用程序通过acmeserver/~staging/note-taking-app部署到登台,生产版本位于acmeserver/note-taking-app(归咎于IT)。

所有媒体文件(如字体)在dev上加载都很好(即,react-scripts启动)。

然而,当我创建和上传登台和生产版本时,虽然.css和.js文件加载正常,但字体却不能。编译后的.css文件看起来有一个正确的路径,但是浏览器http请求得到了一些非常错误的路径(如下所示)。

编译后的main.fc70b10f.chunk.css文件:

@font-face {
  font-family: SairaStencilOne-Regular;
  src: url(note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf) ("truetype");
}

浏览器http请求如下所示。注意,当字体文件仅仅存在于/static/media/中时,它是如何添加到/static/css/中的,以及如何复制目标文件夹。我排除了服务器配置是罪魁祸首的可能性。

推荐人也有部分过错。

GET /~staging/note-taking-app/static/css/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf HTTP/1.1
Host: acmeserver
Origin: http://acmeserver
Referer: http://acmeserver/~staging/note-taking-app/static/css/main.fc70b10f.chunk.css

包。Json文件首页属性设置为。/ notes -taking-app。这就是问题的根源。

{
  "name": "note-taking-app",
  "version": "0.1.0",
  "private": true,
  "homepage": "./note-taking-app",
  "scripts": {
    "start": "env-cmd -e development react-scripts start",
    "build": "react-scripts build",
    "build:staging": "env-cmd -e staging npm run build",
    "build:production": "env-cmd -e production npm run build",
    "test": "react-scripts test",
    "eject": "react-scripts eject"
  }
  //...
}

解决方案

这很冗长,但解决方案是:

根据环境改变PUBLIC_URL env变量 从包中删除主页属性。json文件

下面是我的.env-cmdrc文件。我使用.env-cmdrc而不是常规的.env,因为它将所有内容都放在一个文件中。

{
  "development": {
    "PUBLIC_URL": "",
    "REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
  },
  "staging": {
    "PUBLIC_URL": "/~staging/note-taking-app",
    "REACT_APP_API": "http://acmeserver/~staging/note-taking-app/api"
  },
  "production": {
    "PUBLIC_URL": "/note-taking-app",
    "REACT_APP_API": "http://acmeserver/note-taking-app/api"
  }
}

通过react-router-dom进行路由也可以,只需使用PUBLIC_URL env变量作为basename属性即可。

import React from "react";
import { BrowserRouter } from "react-router-dom";

const createRouter = RootComponent => (
  <BrowserRouter basename={process.env.PUBLIC_URL}>
    <RootComponent />
  </BrowserRouter>
);

export { createRouter };

服务器配置被设置为将所有请求路由到。/index.html文件。

最后,下面是实现上述更改后编译的main.fc70b10f.chunk.css文件的样子。

@font-face {
  font-family: SairaStencilOne-Regular;
  src: url(/~staging/note-taking-app/static/media/SairaStencilOne-Regular.ca2c4b9f.ttf)
    format("truetype");
}

Normally, Create React App ignores the hostname. You may use this variable to force assets to be referenced verbatim to the url you provide (hostname included). This may be particularly useful when using a CDN to host your application.
