How do I set up Hot Module Replacement in my project?

To set up Hot Module Replacement (HMR), you need to configure your build tool. Are you using Webpack or another tool?

I'm using Webpack. What do I need to do?

In your Webpack configuration, you need to add the HotModuleReplacementPlugin and set the devServer to enable HMR.

Can you show me an example of the configuration?

Sure! Here's a basic example:

const webpack = require('webpack');

module.exports = {
  // other configurations...
  plugins: [
    new webpack.HotModuleReplacementPlugin(),
  ],
  devServer: {
    hot: true,
  },
};

Thanks! Is there anything else I should know?

Make sure to also update your entry points to include the HMR client. This will ensure your modules update without a full reload.
