One Get the sound file you want (e.g. sound.mp3) and put it somewhere in your src directory.
Two Add this to your webpack.config.js file. Make sure you have file-loader installed (run npm install --save-dev file-loader if you don’t.)
{ test: /\.mp3$/, loader: 'file-loader', query: { name: 'static/media/[name].[hash:8].[ext]' } }  Three Import the file at the top of your JavaScript file. Put the path relative to the JavaScript file you are loading the sound from.
