This video tutorial guides viewers through setting up a basic project using webpack and Firebase. It covers creating necessary folders, initializing NPM, installing specific versions of webpack and Firebase, and configuring webpack settings. The tutorial emphasizes the importance of using consistent package versions to avoid compatibility issues. It also demonstrates running webpack and using a live server to test the setup. The session concludes with a recap and a preview of the next steps involving Firebase integration.
