Module Hot Replacement (HMR)

This feature allows developers to accept updates for specific modules at runtime, enabling Hot Module Replacement. The code checks if HMR is enabled and then specifies what should happen when a module is updated.

if (module.hot) {
  module.hot.accept('./my-module.js', function() {
    // Handle the updated module or react to the update
  });
}

Require Context

Require context allows developers to dynamically require modules within a certain context, such as all files in a folder matching a regex. The code creates a context for all `.js` files in a folder and iterates over them.

const context = require.context('./folder', false, /\.js$/);
context.keys().forEach((key) => {
  const module = context(key);
  // Use the module
});

DefinePlugin Global Constants

This feature allows access to global constants defined at compile time by webpack's DefinePlugin. The code logs a global constant that could be set to the application's version.

console.log(PROCESS_ENV_VERSION); // Logs the version if defined by DefinePlugin in webpack config
