Webpack devserver react router BrowerRouter 404

I know this has been asked before but I have been fighting with this for a couple of hours now and I cannot find a working setup for local development setup of using react router with the BrowserRouter and the webpack dev server.

When I go to any route that is not the index.html I get a 404 error. I tried multiple configurations from questions here starting from this blospost https://ui.dev/react-router-cannot-get-url-refresh/ but i cannot make it work.

I do see on the initial console output this:

ℹ ｢wds｣: Project is running at http://localhost:3000/
ℹ ｢wds｣: webpack output is served from /
ℹ ｢wds｣: Content not from webpack is served from /Users/danielfrg/workspace/nbviewer.js/dist
ℹ ｢wds｣: 404s will fallback to /
ℹ ｢wdm｣: Hash: 3409aa1e47265f63217d

So I would expect the 404s to fallback to / but its not doing that.

This is my webpack.config.js:

var path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const FileManagerPlugin = require("filemanager-webpack-plugin");
const BundleAnalyzerPlugin = require("webpack-bundle-analyzer")
    .BundleAnalyzerPlugin;

const extractPlugin = {
    loader: MiniCssExtractPlugin.loader,
};

module.exports = (env, argv) => {
    const IS_PRODUCTION = argv.mode === "production";

    const config_dist = {
        entry: [path.resolve(__dirname, "src", "index.js")],
        output: {
            path: path.resolve(__dirname, "dist"),
            filename: "nbviewer.js",
            publicPath: "/",
        },
        module: {
            rules: [
                {
                    test: /\.(js)$/,
                    exclude: /node_modules/,
                    use: ["babel-loader"],
                },
                {
                    test: /\.s?[ac]ss$/,
                    use: [extractPlugin, "css-loader", "sass-loader"],
                    // use: ["null-loader"],
                },
                // Bundle Jupyter Widgets and Font Awesome
                {
                    test: /\.(eot|ttf|woff|woff2|svg|png|gif|jpe?g)$/,
                    loader: require.resolve("url-loader"),
                    // loader: require.resolve("file-loader"),
                    // options: {
                    //     name: "[name].[ext]?[hash]",
                    // outputPath: "assets/",
                    // },
                },
            ],
        },
        plugins: [
            new HtmlWebpackPlugin({
                template: path.resolve(__dirname, "src", "index.html"),
            }),
            new MiniCssExtractPlugin({
                filename: "index.css",
            }),
            new FileManagerPlugin({
                onEnd: {
                    copy: [
                        {
                            source: path.resolve(__dirname, "static"),
                            destination: path.resolve(__dirname, "dist"),
                        },
                    ],
                },
            }),
            // new BundleAnalyzerPlugin(),
        ],
        devServer: {
            port: 3000,
            // contentBase: "/",
            contentBase: path.resolve(__dirname, "dist"),
            historyApiFallback: { index: "/" },
            publicPath: "/",
        },
        node: {
            fs: "empty",
        },
        mode: IS_PRODUCTION ? "production" : "development",
        devtool: "source-map",
    };

    let config = [config_dist];

    return config;
};

Is the solution here to use the proxy as some other questions mention? It looks like some people have it working without that. Thanks for any help!

After playing with the different URL I noticed that a base url like: http://localhost:3000/asdf was indeed being redirected, in my case i was testing with files that had an extension so it was always failing.

To fix it I just had to add: disableDotRule: true.

      devServer: {
            port: 3000,
            contentBase: path.resolve(__dirname, "dist"),
            historyApiFallback: { index: "/", disableDotRule: true },
      }

Hope this helps someone in the future!
