Wie halten Sie Ihre Codebasis wartbar?

That's a fact!. It is very important create a code thinking in the next developer who will do the maintenance, and following a common style guide will help your team save time and have more in the business rules.

I agree with this at a 100%. I would love to state that using a style guide is another form of learning structure for developers, and new team member's integration to the organisation's standard practices as different team member transition. It will also help form an adherence to the organisation's standard rules and conventions which would in turn show in the quality of code and applications produced in respective team. Having had the opportunity to work within organisation's with applications that serve millions of people I can categorically say that style guide (rules and conventions) are things to be enforced within an organisation in order to have a standard code practice and quality gate at different production level.

I personally like to use a consistent coding style when I write my code. This surely means using the same naming conventions, indentation, and commenting style throughout my code.I find out that this makes my code more readable and understandable for other developers who may need to work on it in the future and even for myself. Here are some specific things that I keep in mind when following consistent coding standards: I use a consistent naming convention for variables,functions,and classes. I indent my code to make it easier to read and easy to the eye. I comment my code to explain its purpose and functionality. I avoid using global variables. I break my code down into small,modular functions. I use a code review process to catch errors

To keep a codebase maintainable, adhere to coding standards, document thoroughly, modularize code, use version control, conduct regular code reviews, automate testing, prioritize refactoring, and keep dependencies up-to-date

One of the important aspects of code refactoring that needs to be made clear is the aspect of not changing the code functionality. In a bit to refactoring codebase regularly developers can fall into error of tweaking the functionality (applications objectives) without knowing. In the light of this, the steps to ensure adherence to quality refactoring which includes: Setting clear goals and objectives, writing tests to ensure the code still passes for the objectives without bugs, eliminating duplication as much as possible and finally ensuring optimised performance should always be ensured.

As I see it, meaningful variable names play a pivotal role in crafting maintainable code. Choosing descriptive and intuitive names for variables not only aids in understanding the logic behind the code but also fosters effective collaboration, especially in larger teams. When your colleagues can instantly grasp the purpose and role of a variable by its name, it accelerates the development process, reduces the learning curve, and promotes consistent coding practices. Code is read more often than it's written, and investing in clear variable names pays off exponentially in the long run.

It's also a good practice to allocate developer time and effort to refactoring code. While refactoring code may not immediately give value as opposed to implementing a new feature, the key thing to focus on is the future value refactoring can bring. For instance, implementing a new feature on a messy/poorly maintained code base may take significantly more time and effort as developers relearn existing system behaviours. A clean and well-maintained code base could instead help developers implement new features more quickly and efficiently as less time is spent understanding poorly documented code or bug-tracing.

Refactoring process can help to keep your code under the Clean Code Principles and could be possible to apply SOLID Principles. But, before any refactoring, make sure that will not break any part of your application.

Perform audits of your codebase! I recommend writing code with the idea in mind that someone totally new will be looking at it. Give clear and concise explanations where needed, and be consistent with methodology and standards. Get feedback from your team (from interns, to senior engineers, to engineering managers) on what makes sense and what doesn't.

Running an end-to-end test is key as not all applications that passes the integration testing run end to end (meeting the expected requirements and application scope), and for large organisations that run on fast pace deliveries the temptation to skip some of this tests in order to deliver products to the clients might cost a long term issue. Conclusively, all testing process are vital and needed in order to have a robust application.

Speaking about Unit Tests. This should be required in all kind of software projects. They are very useful to detect bugs and abnormal behavior, in order to ensure reliable deliveries and, consequently, increase the project success final delivery.

Maintaining a firm grasp on Git proves to be of paramount importance. The practice of segregating branches for precise bug fixes and discrete functionalities results in a streamlined Pull Request process, characterized by enhanced transparency and methodical scrutiny. This approach not only amplifies the lucidity of the development cycle but also facilitates a meticulous code review procedure, thereby enabling comprehensive feedback and the upkeep of an uncluttered and intelligible codebase. Moreover, the judicious organization of branches facilitates the seamless integration of new features, ensuring the preservation of main codebase stability.

Version control is smart collaborations, continuous learning and active integration. The process of having a system to document, track, review, and integrate real-time help to optimise and maintain a codebase. As a developer having a grasp of Git should be a vital knowledge to ensure readiness for team collaboration. I have witnessed scenarios where all that saved an organisation from great lose and massive issues was the ability to use Version control to reverse changes to the most stable application state in other to ensure business as usual.

Documentation is the very important for continuous integration and application enhancement. Behind every working application is an effective architecture and well organised documentation for continuous integration. In as much as the role of a Solution Architect is crucial for the team product delivery, keeping track of all documentation is the guarantee for active codebase maintenance.

A code get old, a project get legacy. Can you imagine legacy code without a good documentation or even a good architecture documentation? Terrible. Software Documentation can save time and money!

The SOLID principles is key, but I must say that not all organisations uses this principle. It helps in putting modification restrictions, and also gives a structure to codebase which makes it an important principle for organisations to adopt irrespective of the size (small, meduim and large).

It's hard to apply all the SOLID Principles. But, Single Responsibility with Dependency Inversion, when applied, your code get so clean and easy to maintain, that will produce some kind of hapiness for your developer team.

This basic rule is the most simple secret for maintaining an existing codebase. One of the most important factors influencing the maintainability of code is its readability. The more readable the code is, the easier it is to maintain that code. The more cryptic and difficult to understand code is, the more difficult it is to maintain. The more maintainable your code is the better. An excellent way to make code more maintainable is through loose coupling because Programming is an interface, not an implementation.

The organisation's codebase is it powerhouse. All modifications, enhancement happens there via collaboration and continous delivery, this makes it key to have active codebase maintenance.

"Documentation" means different things to different people, and it needs to be written so that the target audience gets what they need. One size does not fit all, however, the following regularly gets omitted: - A description of what the software is for - How it should work at a high level - Assumptions about the computing environment - high/low security - environmental issues - mission critical (nuclear reactor software, xray machines, etc) - expected life span (exploratory prototype, commercial release, etc) - expected optimizations (least cost to develop, fastest time to market, minimum computing resources) - etc. Knowing your audience answers questions like: - Should an onboarding guide be written? ...
