Before we finish, let's also document the commands we've run into npm scripts. This will make building and serving our application easier in the future.
In the package.json, define the build step with the following scripts property:
"scripts": { "build": "rm -rf dist/ && webpack"}
Then, we will write a script to serve our application. We'd like to specify the host and port of the application using environment variables (instead of hard-coding it), so let's create an .env and an .env.example file, and fill them with the following content:
WEB_SERVER_PORT_TEST=8200WEB_SERVER_HOST_TEST=localhost
Then, create a Bash script at scripts/serve.sh and give it the execute permission:
$ mkdir scripts && touch scripts/serve.sh$ chmod u+x ...
