How can you customize a web development framework or library to meet your needs?

The choice of the framework depends on the project nature, thus you may not need a framework at all if you want to create a simple demo. But for bigger application, you need to consider many things like the functionality, routing, upgrading, testing, compatibility with other libraries you may need (style libraries, translation, ...) Also the expansion of the project; over time the application may get bigger thus you need refactoring and change the project structure. All these aspects can determine which framework is best for your solution.

When customizing libraries and frameworks themselves; insight and project justification is mission critical and MUST come from seasoned developers in the specific library/framework. Frameworks are generally collections of libraries, and libraries fundamentally deal with more engineering constraints than userland code. More often, it is preferred to *use* a framework or library to implement customization at a higher level. Be very aware: Customizing frameworks and libraries incurs the major technical debt of maintaining these changes in parallel to framework updates. Such updates will frequently break downstream software. Unless making a framework; find libraries that have customizable use patterns, instead of customizing the library.

Once you've selected a suitable library, moderately experienced web developers can achieve great strides. When hiring and allocating teams, it may not be obvious to the non-developer that knowledge of the specific framework is a "nice to have", but a very small priority. Exposure to concepts in one framework often translate to others in the same knowledge domain. Scopes should narrow specific windows within the architecture planned before hiring. Ex: A seasoned frontend developer who has never used Bootstrap will have no difficulty doing so. Effecting styles while respecting backend, UI and web service constraints is far more important. Match skills with goals, never qualify by framework. This ensures properly scoped project positions.

Most libraries and frameworks offer out-of-the-box functionality. Sometimes, there are unexpected ways to implement a goal. It is important for teams to survey the libraries and communicate in brainstorming sessions. A frustrating but not-so-rare scenario occurs when teams exhaust themselves implementing features yet the library already paved an unseen, streamlined pathway. For this reason, while the entire team need not be intimately familiar with the framework/library; it is worthwhile to have 1 or 2 advisors who are very familiar. This can often take the form of periodic workshops, use of fractional executives, or full time cross-project talent.

Customizing a web development framework or library involves understanding its architecture and features. Once project requirements are defined, modifications can be made by extending or overriding existing functionality. Hooks or middleware mechanisms can intercept and modify requests, while plugins or modules encapsulate custom logic. Configuration files are adjusted, and templates overridden to align with design needs. Styling and theming may be applied for frontend frameworks. Utilizing APIs and contributing to the community through pull requests fosters collaboration. Thorough testing is crucial to ensure customizations don't introduce bugs.

Maintain the our customization as a separate distribution unit and create a simple automation to deploy the changes. This allows us to iterate more often to test out changes is already meet the requirements or want to upgrade the main framework to the newer version
