Singleton design pattern. JS/TS Examples. |
https://dev.to/ryabinin/singleton-design-pattern-jsts-examples-2f8l

Singleton design pattern JS TS Examples ImplementationPros and ConsExamplesSo why do we need to know design patterns First of all it helps you to save your time Programming is not a new thing a lot of problems has been already solved before Lots of patterns and approaches have been invented and most of them are time tested If you don t want to reinvent the wheel you might be interested to know more about those preexisting patterns and approaches So design patterns are typical solutions to commonly occurring problems in programming In this short article we are going to cover the singleton design pattern This pattern is a type of creational design patterns and probably one of the simplest ones Implementation The Singleton pattern is just a way of creating a single object that is shared amongst a bunch of different resources throughout your application without having to recreate that object or losing the information inside of it It ensures that there is only one instance of a given classFor example we may create a logger class which prints logs and keeps them inside the class Following this patters you have to have a single instance of the logger which prevents losing overwriting the logs list This pattern also provides a way to access the single instance globallyGoing back to our logger class it s pretty much obvious that we need it to be accessible from any file in our project Because errors may appear anywhere and we want to log them Pros and Cons Pros Global variables vs Singleton Comparing to global variables Singletons can not be modified speaking of var in JS Unlike global variables it doesn t exist until instantiated Another advantage is that you are absolutely sure of the number of instances You can manage the state of that instance Cons of using this design pattern Someday when you have a lot of parts of your app rely on that Singleton obj it may became hard to change Singleton obj itself As we already know Singleton s methods could be called from different parts of your app simultaneously at the same time which may cause a data variables within this object to be overwritten read incorrectly FYI there are more cons actually but we re not going to cover all of them in this article Examples JS Example class SingletonLogger prevent modifying the instance property for example set it to null to create a second instance static instance prevent modifying overwriting logs array logs classes in JavaScript may not have a private field named constructor so it s not possible to disable calling constructor in JS if you try new SingletonLogger with private constructor in TS it will throw an error constructor if SingletonLogger instance throw new Error Can not instantiate second singleton SingletonLogger instance this getInstance should be static to be able to call SingletonLogger getInstance static getInstance if SingletonLogger instance SingletonLogger instance new SingletonLogger return SingletonLogger instance log error this logs push error console log error since logs array is private we need to create a getter get logsArray return this logs Usage const logger SingletonLogger getInstance try throw new Error first err catch err logger log err log first err console log logger logsArray log first err const logger SingletonLogger getInstance try throw new Error second err catch err logger log err log second err console log logger logsArray log first err second err const logger new SingletonLogger Error Can not instantiate second singletonTS example class SingletonLogger private static instance SingletonLogger private logs Array lt Error gt private constructor public static getInstance SingletonLogger if SingletonLogger instance SingletonLogger instance new SingletonLogger return SingletonLogger instance log error Error this logs push error console log error get logsArray return this logs Usage const singleton new SingletonLogger TS won t let you do this Constructor of class SingletonLogger is private and only accessible within the class declaration const singleton SingletonLogger getInstance try throw new Error first err catch err singleton log err as Error log first err console log singleton logsArray log first err const sameSingleton SingletonLogger getInstance try throw new Error second err catch err sameSingleton log err as Error log second err console log sameSingleton logsArray log first err second err ConclusionTo be honest I haven t found any use cases in Front End development where singleton design pattern would be really helpful Of course you can create the same logger as we did above or use the cache as a singleton object But I personally think you will rarely have to use it Anyways this design pattern is a part of Gang of Four design patterns and knowing all these patterns will take you to the next level as a dev Thanks for reading Any feedback is appreciated Photo by Lucas Campoi |
