Web development is a diverse task in itself as it not only includes various programming languages but also architectures of different kinds along with other concerns that it becomes difficult to figure out about how and where to start off during the development process. Well, that’s when design patterns come to play as they serve as a template for your web project. This is because design patterns come with certain conventions that give your project ample guidance and a strategic start. These patterns are considered reliable as they are made up by keeping best practices in mind and also because these practices are a result of different experiences of numerous developers.
So, by opting for design patterns, you can avail yourself of the liberty to decide the set of practices that you require. Hence, you will have a clear understanding and idea of what the codes should be doing and what vocabulary you should be used by simply choosing the design patterns. However, most businesses prefer to invest in professional website design and development services to ensure quality results. But it is still a smarter approach that you get enough idea about design patterns and when you should use them.
Top 4 Design Patterns in Web Development
Singleton Design Pattern
Strategy Design Pattern
Now comes the turn of strategy design pattern. Well, you should consider that strategy as a pattern is like an advanced version of an if-else statement. So, that is where you make an interface for a method you have in your base class. Moreover, this interface will then be used to find the right implementation of that method from the derived classes. Thus, in such a case, it will be decided at runtime based on the client. So, this pattern is enormously useful in situations you have required and optional methods for a class. However, some instances of that class will not need the optional methods which cause the errors in inheritance solutions. You can also use interfaces for the optional methods, but then you would have to write the implementation each time you use that class since there will be no default implementation. That is what strategy patterns help you with. This is because you don’t have to look for implementation as it delegates to a strategy interface and that strategy helps you find the right implementation.
Observer Design Pattern
Well, if you have ever used the MVC pattern, you must have already used the observer design pattern. To explain it specifically, it is like the view part of MVC so you have a subject that holds all of the data and its data. Therefore, you have observers like users that contribute to pulling the data from the subject when it is updated. However, there are so many applications for an observer design pattern that it has proven to become an integral part of MVC. This can help you in numerous ways ranging from sending user notifications, filters to handling subscribers, you can all do this by using an observer pattern.
Decorator Design Pattern
Finally, if we talk about the decorator design pattern, you should know that it is incredibly simple. This is because you can have a base class with methods and properties that are present when you require to make a new object with the class. SO, you have some instances of the class that need methods and properties that don’t come from the base class. So, you can add those extra methods and properties to the base class, but that could disturb your other instances. Therefore, you could even create subclasses to hold specific methods and properties you will not put in your base class. So, you can go with either of these approaches to solve your problem but these may create inefficiency. So, that’s where the decorator design pattern comes to play. This is because it makes your code base unattractive to add a few things to an object instance, so you can tack on these specific things directly to the instance.
So, these are some of the top design patterns that can help you in the process of website development. However, you can get better exposure and ideas by hiring a professional web agency.
