The distinction between a website and a web application lies in interactive state, user roles, business logic, and transactional persistence.
Start with a problem statement
Before selecting a framework or language, describe what the software must help a user accomplish. List the people who will use it, the information it needs, and the actions each role can perform. This gives the project a stable reference when new ideas appear during development.
Build a small, testable first version
Prioritise the smallest useful workflow that can be tested with real users. Separate essential requirements from optional improvements, and document assumptions that still need confirmation. A small first release can expose confusing steps and missing requirements before the team invests heavily in advanced features.
Plan for reliability and change
Use version control, meaningful error handling, and tests for important business rules. Keep secrets out of source code and restrict access to sensitive records. Document how the application is configured and deployed.
Developer handover checklist
- Keep source code in version control and document setup and configuration.
- Store secrets outside source code and restrict access to credentials.
- Test important business rules, validation, permissions, and failure paths.
- Log diagnostic details without exposing passwords, tokens, or personal data.
- Document deployment, rollback, backup, and recovery steps.
Verify before deployment
Test changed workflows in staging where possible. Check server logs, browser errors, response codes, and key user journeys after release. Measure the bottleneck before introducing complex optimisation.
