Adapter Pattern Javascript Example

As you probably know from a real domestic world adapter is used to connect two or more things which.

Adapter pattern javascript example. Wikipedia says in software engineering the adapter pattern is a software design pattern that allows the interface of an existing class to be used as another interface. Adapter pattern example consider a scenario in which there is an app that s developed in the us which returns the top speed of luxury cars in miles per hour mph. The adapter acts as a wrapper between two objects. Now we need to use the same app for our client in the uk that wants the same results but in kilometers per hour km h.

This type of design pattern comes under structural pattern as this pattern combines the capability of two independent interfaces. The adapter pattern convert the interface of a class into another interface clients expect. For this example the adapter class needs to fulfill two tasks. Significant improvements can be obtained by applying advanced javascript techniques resulting in more effective robust and maintainable apps.

By introducing an adapter class that implements the filtercoffeemachine interface and wraps the premiumcoffeemachine class you enable your filtercoffeeapp to use the coffee machine. Client receive the results of the call and is unaware of adapter s presence. Adapter is a structural design pattern which allows incompatible objects to collaborate. It wraps an existing class with a new interface which is why it is also known as the wrapper design pattern.

Adapter pattern works as a bridge between two incompatible interfaces. This pattern involves a single class which is responsible to join functionalities of independent or incompatible interfaces. Before we dive into adapter pattern example in javascript let s define what it is at all. Adapter pattern lets you wrap an otherwise incompatible object in an adapter to make it compatible with another class.

This one is much more complicated because 1 it s implemented in javascript unlike the console and 2 it send its log to the server via ajax which also means that it must url encode the data which won t be shown here because it doesn t have anything to do with the adapter pattern. The example given is not optimized for javascript. It catches calls for one object and transforms them to format and interface recognizable by the second object. The adapter design pattern is a strtuctural design pattern used to make two unrelated and incompatible interfaces or classes work together that could not be achieved otherwise due to mismatched interfaces.
