When to and When Not to Use Frameworks
We developers are lazy, like everyone else – and with good reason: why should we make something again that already exists? Frameworks and third party code in general help us to avoid having to start completely from scratch on every project.
They mean less work for us and can bring bring features into our project that we might not be able to implement ourselves. We can learn from frameworks and improve our own code. But we can also contribute our own improvements to many open source frameworks. Sounds good so far - so why not use as many of them as possible?
This probably comes as no surprise, but frameworks have drawbacks: if we use them, we create dependencies and technical debt. In principle, any code you didn't write yourself is a potential security risk (see for example the Event Stream Incident). Therefore we have to keep an eye on security updates for our frameworks in particular.
As always in life, the right answer is neither black nor white: if used correctly, third-party frameworks and code can not only save time and money, but also make your product and your skills better. If used incorrectly, they can make your work much more difficult or even lead to a security disaster. I would recommend the following basic rule: as much third party code as necessary, but as little as possible.
Being clear about what the pros and cons of frameworks can be is the most important thing and helps to make the right decision in every situation.
Advantages of frameworks
- We can include features that we could not implement ourselves
- We have to write less code and save time and money
- We can learn from (good) frameworks
- We can even contribute our own improvements to open source frameworks
Disadvantages of frameworks
- Any third-party code is a potential security risk
- Frameworks need to be updated regularly (and as a result, possibly your code as well)
- Frameworks can bloat your codebase (or application) unnecessarily
- Frameworks can prevent you from improving your skills
As with most things in life, I would recommend to follow the basic rule "as much as necessary, as little as possible" and to use frameworks sparingly, but to definitely use them where they make sense!
