I was trying to migrate a typical HTML site to a "light" React app. Therefore, I have installed React without create-react-app.

I configured Webpack and then file-loader to use fonts in the CSS files. But I am still getting errors when compiling because it does not recognize the file loaders (I also tried ttf-loader and url-loader).

I have been reading similar questions but neither of their solutions works on this case.

The project's directory structure looks like this:

  • webpack.config.js
  • src
    • index.js
    • css
      • style.css
    • fonts
      • pgroofrunners.ttf

This is my current Webpack configuration (webpack.config.js):

const path = require('path');
const HtmlWebpackPlugin = require('html-webpack-plugin');

module.exports = {
  entry: path.resolve(__dirname, 'src/index'),
  output: {
    path: path.resolve(__dirname, 'dist'),
    filename: 'bundle.js'
  },
  module: {
    rules: [
        {
            test: /\.js$/,
            include: path.resolve(__dirname, 'src'),
            use: ['babel-loader']
        },
        {
            test: /\.(woff(2)?|ttf|eot|svg)(\?v=\d+\.\d+\.\d+)?$/,
            use: [
              {
                loader: 'file-loader',
                options: {
                  name: '[name].[ext]',
                  outputPath: 'fonts/'
                }
              }
            ]
          }
    ]
  },
  devServer: {
    contentBase:  path.resolve(__dirname, 'dist'),
    port: 9000
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: "src/index.html"
    })
  ]
};

So, when I run webpack-dev-server --mode development it compiles but then crashes with the following errors:

C:\Web\pwa-static2>yarn serve
yarn run v1.17.3
$ webpack-dev-server --mode development

You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders

I guess this is what is crashing the app in **src/css/style.css*:

@font-face {
    font-family: pgRoofRunners;
    src: url("../fonts/pgroofrunners.ttf");
}

How can I solve this?

You need a style loaderAlex W

It looks like you are importing the CSS somewhere with webpack. In order to understand CSS, webpack needs a loader for that as well. Usually you have something like this in your module.rules:

{
  test: /\.css$/,
  use: [MiniCssExtractPlugin.loader, 'css-loader']
}

or, if you don't use MiniCssExtractorPlugin:

{
  test: /\.css$/,
  use: ['style-loader', 'css-loader']
}

Instead of file-loader, I used url-loader (need to be installed).

{ test: /\.(png|woff|woff2|eot|ttf|svg)$/, loader: 'url-loader?limit=100000' }
