海外TECH	DEV Community	Best Ways To Use "Generics" In Typescript	https://dev.to/arafat4693/best-ways-to-use-generics-in-typescript-51fi	Best Ways To Use quot Generics quot In TypescriptGenerics in Typescript allows you to create a component that can work with different types This lets users use these components with their specific type Before reading this article please read my article about TS utility types as It will help you to understand this article better Table of contents Generics with type Generic functions Generics with built in functions Inferring the types Constraints on type arguments Constraints in functions Use as when necessary Multiple generics Defaults in type arguments Class Types in GenericsConclusionHere are few possible ways to use Generics in Typescript Generics with typeThe easiest way of using generics is with type For example type MyData lt Type gt data Type type DataAsString MyData lt string gt type DataAsString data string Because we passed string as a type parameter our data will be string type Likewise if we pass the number type our data will be of number type And that s the beauty of generics You can work with any type type MyData lt Type gt data Type type DataAsString MyData lt number gt type DataAsString data number Generic functionsAs you can pass arguments to a function you can also pass type arguments to a function For example const fetchData lt Type gt url string Promise lt Type gt gt return fetch url fetchData lt name string age number gt api books then res gt console log res res name string age number We passed name string age number as a type argument to the fetchData function And this type argument tells res what It is supposed to be because this is what s getting typed in Promise lt Type gt So now the function fetchData has become a generic function A generic function is just a normal function but includes a type argument If we want to pass another type our res will replicate that same type const fetchData lt Type gt url string Promise lt Type gt gt return fetch url fetchData lt id number email string gt api books then res gt console log res res id number email string Generics with built in functionsYou can even use generics with built in functions For example you can create a Set that stores only numbers by using the Set constructor with a type parameter const numberSet new Set lt number gt numberSet add numberSet add numberSet add Similarly you can create a Map that maps strings to numbers by using the Map constructor with type parameters for the key and value types const stringToNumberMap new Map lt string number gt stringToNumberMap set one stringToNumberMap set two stringToNumberMap set three Inferring the typesIf your type argument looks similar to your runtime argument then you don t have to pass a generic type to your function For example function identity lt T gt arg T T return arg const result identity lt number gt const result numberconst result identity lt string gt hello const result stringWhile the above example looks correct we can simplify it more function identity lt T gt arg T T return arg const result identity const result numberconst result identity hello const result stringIn this case because we are not passing any type argument then Typescript will look in the runtime argument to see If It can infer anything from it So the return type is inferred from the runtime argument type and the function returns the same type as it receives Constraints on type argumentsIn our following example we wanted to be able to use the ReturnType utility type but the compiler could not prove that every type was a function it could be a string or number and as we know that ReturnType works only with functions so it warns us that we can t make this assumption type GetPromiseData lt T gt Awaited lt ReturnType lt T gt gt Error Type T does not satisfy the constraint args any gt any type PromiseResult GetPromiseData lt gt Promise lt id string email string gt gt So to make It clear to Tyepscript We have to say that T is only a function and we can do this by adding extends args any gt any after the T type GetPromiseData lt T extends args any gt any gt Awaited lt ReturnType lt T gt gt type PromiseResult GetPromiseData lt gt Promise lt id string email string gt gt Constraints in functionsIn our following example we wanted to access the address property of arg but the compiler could not prove that every type has a address property so it warned us that we couldn t make this assumption function myFunc lt Type gt arg Type Type console log arg address Property address does not exist on type Type return arg To fix this error we can create an interface with address property in it and extend it with the Type argument interface IDetails address string function myFunc lt Type extends IDetails gt arg Type Type console log arg address Now we know it has a address property so no more error return arg Because the generic function is now constrained it will no longer work over all types myFunc true error Argument of type boolean is not assignable to parameter of type IDetails Instead we need to pass in values whose type has address property myFunc length address Something Use as when necessarySometimes using as is the best thing you can do when using generics For example const ObjectKeys lt T extends gt obj T Array lt keyof T gt gt return Object keys obj Error Type string is not assignable to type keyof T const result ObjectKeys id email me gmail com Here we are getting an error because the Object keys method returns an array of string values and TypeScript cannot guarantee that the string values returned by Object keys actually correspond to valid keys of the generic type T To fix this error we can explicitly typecast the Object keys result to an array of keyof T using the as keyword const ObjectKeys lt T extends gt obj T gt return Object keys obj as Array lt keyof T gt const result ObjectKeys id email me gmail com Multiple genericsSometimes we have to use multiple generics to make sure that we are getting back a certain type Consider the following example function getProperty lt T gt obj T key keyof T return obj key let x a b b c true d getProperty x a return type string number booleanWhile the above example is correct the problem is that the return type is not explicit Return type is an union consisting of different types To fix this problem we can use multiple generic types function getProperty lt T Key extends keyof Type gt obj Type key Key return obj key let x a b b c true d getProperty x a return type numberIn this example we ve added generic type parameter Key to represent the key type of the object T So now we will get a specific return type only function getProperty lt Type Key extends keyof Type gt obj Type key Key return obj key let x a b b c true d getProperty x c return type boolean Defaults in type argumentsWe can also use default types in generics Consider the following example const makeSet lt T gt gt return new Set lt T gt const mySet makeSet const mySet Set lt unknown gt Here we are getting unknown because we didn t pass any type argument to makeSet function We can solve this problem by either passing a type argument like this makeSet lt number gt or by specifying a default type const makeSet lt T number gt gt return new Set lt T gt const mySet makeSet const mySet Set lt number gt Class Types in GenericsWe can also refer to class types by their constructor functions For example function create lt Type gt c new Type Type return new c Here s a breakdown of how the function works The create function is declared with a type parameter Type representing the type the function will make The function takes a single argument c an object representing a constructor function for the type Type The argument has the type new Type an object type specifying a constructor function that takes no arguments and returns a value of type Type The new keyword is used to create a new instance of the type Type inside the function by calling the constructor function passed as the argument c The new keyword creates a further object of the type Type and returns it as the result of the function The function s return type is specified as Type which ensures that the function returns an instance of the type specified by the type parameter Here s an example of how the create function can be used class MyClass constructor public value string const instance create MyClass console log instance value Output undefinedThis example defines a simple class MyClass with a single property value We then call the create function passing the MyClass constructor function as the argument The create function creates a new instance of MyClass using the constructor function and returns it as an instance of type MyClass ConclusionIn conclusion TypeScript s support for generics provides a powerful tool for writing type safe and reusable code By defining generic types and functions you can create code that works with various types while maintaining strict type checking To make the best use of generics in TypeScript it s essential to understand how to define and use generic types specify constraints on generic type parameters and use type inference to reduce the need for explicit type annotations Additionally it s crucial to use generics to maintain good code readability and avoid unnecessary complexity When appropriately used generics can significantly improve the quality and maintainability of your TypeScript code By taking advantage of TypeScript s powerful type system and the flexibility of generic types you can create highly reusable and expressive code while still maintaining the strong type safety that TypeScript provides Visit ‍My
