Angular's opinionated structure suits large forms-heavy applications and teams that value strict conventions. Paired with Node.js and MongoDB, it makes a consistent, typed stack from browser to database.
Where we use it
Enterprise portals, back-office systems, booking and scheduling tools, and long-lived products where many developers will touch the code over the years.
What you get
Feature-module architecture, reactive forms with proper validation, RxJS-based state where it helps, a documented REST API, and automated tests at the service and component level.
