The document discusses ExpressJS, the most popular Node.js web application framework. It notes that ExpressJS is easy to get started with but may lack experience to fully understand needs. The document then covers key aspects of ExpressJS like routing, middleware, and default architecture. It proposes different schemas and approaches for cleaning out and separating concerns in ExpressJS applications, such as using entity loaders, data mappers, validators, and controlling flow through events rather than direct method calls.
