Question

我正在尝试将一个favicon添加到我使用webpack创建的基于React的网站上。添加一个favicon是一个彻头彻尾的噩梦，我尝试了许多解决方案无济于事。推荐给我的最新解决方案名为＆＃39; favicons-webpack-plugin＆＃39;可以在这里找到：https://github.com/jantimon/favicons-webpack-plugin。

如果有人能告诉我我做错了什么，我们将非常感谢您的协助。

app.use(bodyParser.json());
app.use(express.static(path.join(__dirname, 'build')));
app.use(favicon(__dirname + '/public/favicon.ico'));

app.use(logger('dev'));

/* Server Initialization */
app.get('/', (req, res) => res.sendFile('index.html'));
var port = process.env.PORT || 3000;
app.listen(port, () => console.log(`Server initialized on // ${new Date()}`));

Answer 1

这就是您所需要的：

new HtmlWebpackPlugin({
    favicon: "./src/favicon.gif"
})

那肯定是在将“ favicon.gif”添加到文件夹“ src”之后。

这会将图标转移到您的构建文件夹中，并将其包含在标签中，例如<link rel="shortcut icon" href="favicon.gif">。这比仅使用copyWebpackPLugin

导入更安全

Answer 2

对于未来的googlers：您也可以使用copy-webpack-plugin并将其添加到webpack的生产配置中：

plugins: [
  new CopyWebpackPlugin([
    // relative path is from src
    { from: './static/favicon.ico' }, // <- your path to favicon
  ])
]

Answer 3

浏览器在/favicon.ico中查找您的favicon，这就是它所需要的位置。您可以通过导航到[address:port]/favicon.ico并查看是否显示图标来仔细检查是否已将其放置在正确的位置。

在开发模式下，您正在使用historyApiFallback，因此需要配置webpack以显式返回该路由的图标：

historyApiFallback: {
    index: '[path/to/index]',
    rewrites: [
        // shows favicon
        { from: /favicon.ico/, to: '[path/to/favicon]' }
    ]
}

在server.js文件中，尝试明确重写网址：

app.configure(function() {
    app.use('/favicon.ico', express.static(__dirname + '[route/to/favicon]'));
});

（或者您的设置更喜欢重写网址）

我建议生成一个真正的.ico文件，而不是使用.png，因为我发现它在浏览器中更可靠。

Answer 4

将您的favicon简单地添加到公共文件夹中应该这样做。确保favicon被命名为＆＃34; favicon.ico＆＃34;。

Answer 5

另一种选择是

npm install react-favicon

在您的应用程序中，您只需：

   import Favicon from 'react-favicon';
   //other codes

    ReactDOM.render(
        <div>
            <Favicon url="/path/to/favicon.ico"/>
            // do other stuff here
        </div>
        , document.querySelector('.react'));

Answer 6

与添加任何其他外部脚本或样式表相同。您要做的就是专注于提供正确的路径和 rel 和类型。

注意：当我的收藏夹图像位于 assets文件夹中时，它未显示收藏夹。因此，我将图像复制到与index.html 相同的文件夹中，并且可以正常工作。

<head>
    <link rel="shortcut icon" type="image/png/ico" href="/favicon.png" />
    <title>SITE NAME</title>
</head>

对我有用。希望它也对您有用。

Answer 7

使用文件加载器：

{
    test: /\.(svg|png|gif|jpg|ico)$/,
    include: path.resolve(__dirname, path),
    use: {
        loader: 'file-loader',
        options: {
            context: 'src/assets',
            name: 'root[path][name].[ext]'
        }
    }
}

Answer 8

这就是我的做法。

public / index.html

我已经添加了生成的收藏夹链接。

...
<link rel="icon" type="image/png" sizes="32x32" href="%PUBLIC_URL%/path/to/favicon-32x32.png" />
<link rel="icon" type="image/png" sizes="16x16" href="%PUBLIC_URL%/path/to/favicon-16x16.png" />
<link rel="shortcut icon" href="%PUBLIC_URL%/path/to/favicon.ico" type="image/png/ico" />

webpack.config.js

new HTMLWebpackPlugin({
   template: '/path/to/index.html',
   favicon: '/path/to/favicon.ico',
})

注意

我在开发人员模式下使用historyApiFallback，但是我不需要进行任何其他设置来获得Favicon的工作，也不需要在服务器端进行操作。

Answer 9

在我的情况下-我正在使用Webpack 2.4.1在调试模式下运行Visual Studio（2017年专业版）-必须将favicon.ico放入项目的根目录，即文件夹的正确位置src不在文件夹public中，尽管根据https://create-react-app.dev/docs/using-the-public-folder，后者应该是官方位置。

Answer 10

我使用favicons-webpack-plugin

const FaviconsWebpackPlugin = require("favicons-webpack-plugin");

module.exports={
plugins:[
    new FaviconsWebpackPlugin("./public/favicon.ico"),
//public is in the root folder in this app. 

]
}

Answer 11

如果不使用Create React App，当前的正确答案是下一个：

new HtmlWebpackPlugin({
   favicon: "./public/fav-icon.ico"
})

如果使用CRA，则可以修改公共目录中的manifest.json

Answer 12

我将给出添加favicon的简单步骤:-)

创建徽标并另存为logo.png
将logo.png更改为favicon.ico

注意：：保存时favicon.ico不是favicon.ico.png
可能要花一些时间

如果等不及了，请更改manifest.json中的图标大小

Answer 13

This worked for me:

Add this in index.html (inside src folder along with favicon.ico)

**<link rel="icon" href="/src/favicon.ico" type="image/x-icon" />**

webpack.config.js is like:

 plugins: [new HtmlWebpackPlugin({`enter code here`
        template: './src/index.html'
    })],

Answer 14

将公用文件夹中的favicon.ico替换为您的公用文件夹，

Answer 15

Ctrl+f5 清除浏览器缓存

使用React和Webpack添加Favicon

15 个答案:

public / index.html

webpack.config.js
