Containment, Specialization and Inheritance in React-Native/React |
https://dev.to/shivambmgupta/containment-specialization-and-inheritance-in-react-native-react-dlo

Containment Specialization and Inheritance in React Native ReactIn this blog I m going to talk about Containment Specialization and Inheritance in React Native React the difference between them and how you can use them to reuse your code First while the examples shown below are related to react native the theory is also applicable to react The concepts might help you to go DRY Let s discuss these points one by one ContainmentWhen you wrap your component s within a higher order component it s a containment Some components don t know their children ahead of time Some common cases are Sidebar Dialog And for the sake of reusability some components better be generic The following problem can make this clear Problem Statement We have a table of n rows and two columns The columns can hold not just the text but any other JSX component Button Image Icon too However it s is known that it s going to be a text for of the time Solution React containment model can be useful in these cases The idea is to create a wrapper ーGenericRow that can hold any JSX component Furthermore we can create a CustomRow for Text component only This is also called Specialization Yes I know that I ve been talking a lot so let me write the code for you Generic Row that doesn t know about its children const GenericRow props gt lt View props gt Left column or Left child lt View style styles column gt props left lt View gt Right column or Right child lt View style styles column gt props right lt View gt lt View gt Specialization of our Generic Row This component is going to be used when it s known that left and right are texts const CustomRow left right props gt lt Generic props Left child left lt Text gt left toString lt Text gt Right Child right lt Text gt right toString lt Text gt gt Child of CustomRow First Row const NameRow props gt lt CustomRow left Developer s Name right Shivam Gupta gt Second Row for the age const AgeRow props gt lt CustomRow left Age right gt Action Connect Third row const ConnectActionRow props gt Notice Generic Row not a CustomRow lt GenericRow left lt Text gt Connect lt Text gt right lt Button title Hit me gt gt Here CustomRow is a specialization of the GenericRow which is going to be used frequently as per the problem statement Notice that the ConnectActionRow component is contained by the GenericRow and not by the CustomRow unlike the NameRow and AgeRow Just using concepts of containment we have the code which is easier to read debug and maintain Now let s talk about specialization Specialization Sometimes a component is a special case of the other component For example Error Text traditionally bold and red is a special case of Text The following problem will help you understand this better Problem Statement You re creating a medium sized non trivial react native application that is going to have screens You require to prompt the danger text for validation error on at least to screens Solution You ll create a separate component for it Of course Any sane developer would do that If that s the case you already know about Specialization For beginners let me just write a code const Error children fontFamily style gt User may overwrite the color or fontWeight using his own style lt Text style color “red fontWeight bold Notice this written after the our style letting user to overwrite color and fontWeight style gt children lt Text gt Again the idea for this implementation is to use the DRY principle and at the same time allow the user of this component to overwrite our default stying whenever the developer wants InheritanceReact neither prefers nor does provide anything much for inheritance Most of the time you re not going to need it Whatever you could do using inheritance you can achieve the same using Containment or Specialization The following is the statement from the react s official documentation “At Facebook we use React in thousands of components and we haven t found any use cases where we would recommend creating component inheritance hierarchies Difference between Containment Specialization and InheritanceWhile Containment Speicializtion and Inheritance may sound similar but they are very different The following may help you understand it The table CONTAINS HAS rows Neither table is a specialization of rows nor it s an inheritance Pulsar IS a Bike Neither this is an example of containment nor specialization Welcome Dialog is a special case of Dialog Neither this is an example of containment nor inheritance The difference between containment and inheritance is of IS HAS relationship ConclusionThe main objective of the containment and specialization concept is to follow the DRY Don t Repeat Yourself principle Because redundant code is hard to maintain harder to debug and using these concepts will make your code maintainable and less error prone |
