Choosing the right architecture is rarely a purely technical decision.
In real-world projects, architectural choices are influenced by many external factors such as:
- client requirements
- regulatory constraints
- legacy systems
- security policies
- team expertise
- long-term maintainability
The most important factor is almost always the client's requirements and environment.
In regulated industries such as Healthcare, Insurance, or Finance, even small technical decisions may require formal approval.
For example, in one healthcare project I worked on, introducing a new library required a review process that lasted several months. This was necessary due to strict compliance and security requirements.
In such environments, architectural decisions cannot be made purely from an engineering perspective. They must consider:
- compliance policies
- security audits
- internal approval processes
- compatibility with existing systems
These constraints often influence the technology stack far more than developer preferences.
Before making any architectural decisions, it is critical to fully understand the product itself.
This usually requires close collaboration with:
- the client
- product owners
- business analysts
- other engineering teams
The goal is to clearly answer one fundamental question:
What problem are we actually solving?
Architecture should always support the product's goals, not the other way around.
In addition to functional requirements, I follow several non-functional principles when selecting technologies and frameworks.
Technology should be familiar to the team working on the project.
Using niche or obscure frameworks often creates unnecessary friction:
- onboarding new engineers becomes harder
- hiring becomes more difficult
- more time is spent fighting the tooling instead of solving business problems
Choosing well-known and widely adopted technologies usually results in more predictable development.
Large and active communities provide significant advantages:
- better documentation
- more third-party libraries
- faster problem resolution
- more production experience shared by other teams
Strong community support dramatically reduces long-term engineering risks.
Frameworks with a well-defined structure can help maintain architectural consistency.
For example, NestJS encourages a layered architecture and clear module boundaries. While it does not prevent alternative patterns, it provides a strong starting point for organizing large codebases.
In contrast, more flexible frameworks such as Express allow multiple architectural styles, which can lead to inconsistencies across projects if strong conventions are not established.
New technologies are often presented as revolutionary solutions.
However, the JavaScript ecosystem has seen many frameworks that gained short-term popularity and then disappeared.
For production systems, stability is often more valuable than novelty.
Well-established technologies usually offer:
- better long-term support
- more mature tooling
- fewer unexpected risks
