Every release is a responsibility. Even a small improvement can break critical processes if it is released without verification. To avoid this, developers use checklists. They help make sure everything is ready for production, and the team and users will not face any surprises.
1. Code and style
The code is formatted and corresponds to the agreed style guide.
There are no commented pieces, temporary stubs, and
console.log().The names of variables and functions are clear, without "magic numbers".
2. Tests and coverage
All unit tests are successful.
Tests for the new logic have been written.
Integration interaction with other modules has been checked.
If there are no tests, manual verification is required.
3. Logging and errors
Errors are handled correctly and do not fall "into nowhere".
Added the necessary logs for monitoring.
Removed unnecessary debug logs.
4. Safety
User data is validated at the entrance.
No SQL injection and XSS.
Passwords and tokens are not stored in the code.
Feature access rights checked.
5. Performance
The new logic does not slow down critical scenarios.
No unnecessary queries to the database and API.
The behavior under load was checked.
6. UI and UX
The interface is displayed correctly on all supported devices.
Styles do not conflict with existing components.
There are no "broken" layouts on mobile.
The texts are clear, without errors.
7. Documentation and team
Updated API description or internal documentation.
Colleagues know about the new feature and know how to use it.
If you need database migrations, they are documented.
8. Deploy and monitor
The configs for production are correct.
A rollback or hotfix plan is configured.
There are metrics and alerts to track the feature's performance.
Total
A checklist is not a formality, but a tool that saves time, money and nerves.
