We have a very large frontend in a monorepo, worked on by many different teams simultaneously. Moving to micro-frontends is impossible. How to minimize the risks of different teams affecting each other's work?

To minimize the risks of mutual influence of teams when working on a large frontend in a monorepo, the following approaches can be used:

• Clear separation of responsibilities. Define code zones responsible for each team and restrict their rights to modify others' areas.

• Modularity and component isolation. Structure the project so that components are as independent as possible, with clearly defined APIs and contracts.

• Code review and automated checks. Implement strict review processes to prevent changes from breaking others' functionality, and use linters and tests.

• Automated testing and CI/CD. Set up test coverage and continuous integration to quickly identify regressions.

• Use of feature flags. Allows enabling and disabling new features without risking the entire system.

• Documentation and communication. Regular meetings, common coding standards, and documentation help avoid conflicts.

Example of a structure with component isolation:

/src
  /teamA
    /components
    /utils
  /teamB
    /components
    /utils
/shared
  /ui-kit
  /utils

This way, teams work in their folders and minimally intersect.
