26 | 27 | The Useful Types library is an indispensable tool for any developer who works with TypeScript on a regular basis. This library is designed to provide a wide range of common types used in everyday software development. 28 | 29 | Often, developers find themselves writing and rewriting the same types in different projects. This library aims to solve this problem by providing a complete set of well-defined and extensively tested types. 30 | 31 | The library of useful types consists of a number of type definitions ranging from the most basic to the most advanced. These include: 32 | 33 | - Basic types such as strings, numbers, and Booleans. 34 | - Complex types such as promises, functions and classes. 35 | - Utility types such as ClassConstructor, which allows the creation of instances of a given class. 36 | - Custom types that are common in many projects, such as user objects, settings, events, etc.a 37 | 38 | ## Project Status 39 | 40 | ![Alt](https://repobeats.axiom.co/api/embed/f12386845c45e3ad38341c8c31f11785d753a922.svg "Repobeats analytics image") 41 | 42 | ## Contributors 43 | 44 | 45 | 46 | 47 | 48 | 49 | 50 | 51 | 52 | 53 |

This can be useful when you want to ensure that no mutations can be performed on the array. 3 | 4 | ## Definition 5 | ```typescript 6 | export type AsReadonlyArray = readonly [...T]; 7 | ``` 8 | 9 | ## Type Parameters 10 | - `T`: This type parameter represents the array type that you want to convert into a readonly array type. 11 | 12 | ## Return Value 13 | - `AsReadonlyArray`: The return type is a readonly array type that corresponds to `T`. Any attempt to perform array mutations (like push or pop) will result in a compile-time error. 14 | 15 | ## Example 16 | To use it with a specific array type: 17 | ```typescript 18 | type MyArray = number[]; 19 | 20 | type MyReadonlyArray = AsReadonlyArray; // readonly number[] 21 | ``` 22 | 23 | ## Example Implementation 24 | ```typescript 25 | import { AsReadonlyArray } from "typescript-dev-utils"; 26 | 27 | type MyTuple = [string, number, boolean]; 28 | 29 | // Creating a readonly tuple using AsReadonlyArray 30 | const tuple: AsReadonlyArray = ["string", 123, true]; 31 | // You can access the elements of the tuple but cannot modify it 32 | console.log(tuple[0]); // Returns: "string" 33 | console.log(tuple[1]); // Returns: 123 34 | console.log(tuple[2]); // Returns: true 35 | ``` 36 | 37 | ## Note 38 | `AsReadonlyArray` can be useful when you want to protect an array from being mutated. However, remember that TypeScript is a compile-time type system and cannot guarantee type safety at runtime. -------------------------------------------------------------------------------- /docs/ArrayUtils/NonEmptyArray.md: -------------------------------------------------------------------------------- 1 | # NonEmptyArray 2 | `NonEmptyArray` is a utility type that represents an array containing at least one element. 3 | 4 | ## Definition 5 | 6 | ```ts 7 | export type NonEmptyArray = [T, ...T[]]; 8 | ``` 9 | 10 | ## Parameters 11 | - `T`: This type parameter represents the type of elements that the array can contain. 12 | 13 | ## Return Value 14 | - `NonEmptyArray`: The return type is an array of `T` containing at least one element. 15 | 16 | ## Examples 17 | ```ts 18 | // For use with a specific type: 19 | type MyNonEmptyArray = NonEmptyArray; 20 | const validArray: MyNonEmptyArray = [1]; // This is valid. 21 | const invalidArray: MyNonEmptyArray = []; // This will give a compilation error. 22 | 23 | // For use with type 'any': 24 | type AnyNonEmptyArray = NonEmptyArray; 25 | const anyValidArray: AnyNonEmptyArray = [1, 'string', {}, []]; // This is valid. 26 | const anyInvalidArray: AnyNonEmptyArray = []; // This will give a compilation error. 27 | ``` 28 | ## Example Implementation 29 | 30 | ```ts 31 | import { NonEmptyArray } from "typescript-dev-utils"; 32 | 33 | // Implementation of the NonEmptyArray type 34 | function isNonEmptyArray(arr: NonEmptyArray) { 35 | return arr[0]; 36 | } 37 | const arr = [1, 2, 3, 4, 5]; 38 | 39 | const first = isNonEmptyArray([arr[0]]); 40 | console.log(first) // Returns: 1 41 | console.log(arr.length) // Returns: 5 42 | 43 | ``` 44 | 45 | ## Note 46 | 47 | `NonEmptyArray` can be useful for guaranteeing the existence of at least one element in an array, but it cannot guarantee "non-emptiness" at runtime. If it is necessary to verify that an array is not empty at runtime, you will need to perform that check explicitly in your code. 48 | -------------------------------------------------------------------------------- /docs/ArrayUtils/UnboxArray.md: -------------------------------------------------------------------------------- 1 | # UnboxArray 2 | `UnboxArray` is a utility type that takes an array type and returns the type of the elements contained in that array. It is useful when you want to work with the type of elements in an array, rather than the array itself. 3 | 4 | ## Definition 5 | ```ts 6 | export type UnboxArray = T extends (infer U)[] ? U : T; 7 | ``` 8 | 9 | ## Parameters 10 | - `T`: This type parameter represents the type of the array you want to unpack. 11 | 12 | ## Return Type 13 | - `UnboxArray`: The return type is the type of the elements contained in the array `T`. If `T` is not an array type, the return type will be `T` unchanged. 14 | 15 | ## Examples 16 | For use with a specific array type: 17 | ```ts 18 | type MyArrayType = number[]; 19 | type MyElementType = UnboxArray; // number. 20 | 21 | // If you use it with a non-array type, you will get the same type: 22 | type MyNonArrayType = string; 23 | type MyNonArrayElementType = UnboxArray; // string 24 | ``` 25 | 26 | ## Example Implementation 27 | ```ts 28 | import { UnboxArray } from "typescript-dev-utils"; 29 | import { expectType } from "tsd"; 30 | 31 | // Function to get the type of the first element in an array 32 | const getElemento = (arr: T): UnboxArray => { 33 | return arr[0] as UnboxArray; 34 | }; 35 | 36 | // Example usage 37 | const miArray = ["Hola", "Mundo"]; 38 | 39 | const resultado = getElemento(miArray); 40 | 41 | // Type assertion and expectation 42 | expectType>(resultado); 43 | expect(resultado).toBe("Hola"); 44 | ``` 45 | 46 | ## Notes 47 | `UnboxArray` can be useful for working with array element types. However, remember that TypeScript is a compile-time type system and cannot guarantee type consistency at runtime. -------------------------------------------------------------------------------- /docs/ClassUtils/ClassConstructor.md: -------------------------------------------------------------------------------- 1 | # Class Constructor 2 | `ClassConstructor` is a utility type that represents class construction in TypeScript. 3 | 4 | ## Definition 5 | 6 | ```ts 7 | export type ClassConstructor = new (...args: any[]) => T; 8 | ``` 9 | 10 | ## Parameters 11 | - `T`: This type parameter represents the type of the object that will be returned by the class constructor. By default it is `any`, which means it can be any type of object. However, if you want more control over the type that the constructor can return, you can provide a specific type using `ClassConstructor`. 12 | - `...args: any[]`: This represents any number of arguments that the class constructor can accept. Since this is an `any[]` type, the arguments can be of any type and in any number. 13 | 14 | ## Return Value 15 | - `T`: The return type is `T`, which is the same type that was provided to the type parameter when using `ClassConstructor`. In other words, the class constructor will return an object of type `T`. 16 | 17 | ## Examples 18 | ```ts 19 | type MyClassConstructor = ClassConstructor; 20 | const myClassInstance: MyClass = new MyClassConstructor(args); 21 | 22 | // For use with any type: 23 | type AnyClassConstructor = ClassConstructor; 24 | const anyClassInstance: any = new AnyClassConstructor(args); 25 | ``` 26 | ## Example Implementation 27 | ```ts 28 | import { ClassConstructor } from "typescript-dev-utils"; 29 | import { User } from "@/test/utils/UserClass"; 30 | 31 | // Implementation of the ClassConstructor type 32 | function instanceCreator(Cls: ClassConstructor, ...args: unknown[]): T { 33 | return new Cls(...args); 34 | } 35 | 36 | // Creating an instance of User using the ClassConstructor type. 37 | const user = instanceCreator(User, "John Doe", 30); 38 | 39 | // Verification of the User instance 40 | console.log(user instanceof User); // Returns: true 41 | console.log(user.name); // Returns: "John Doe". 42 | console.log(user.age); // Returns: 30 43 | ``` 44 | -------------------------------------------------------------------------------- /docs/ClassUtils/ClassInstance.md: -------------------------------------------------------------------------------- 1 | # ClassInstance 2 | 3 | `ClassInstance` is a utility type that fetches the type of an instance from a given class. 4 | This type becomes useful when you have a reference to a class (constructor) and want to obtain the type of an instance from that class. 5 | 6 | ## Definition 7 | 8 | ```typescript 9 | export type ClassInstance = T extends new (...args: any[]) => infer R ? R : any 10 | ``` 11 | 12 | ## Parameters 13 | 14 | - `T`: This type parameter represents the class (constructor) from which you want to obtain the instance type. 15 | 16 | ## Return Value 17 | 18 | - `ClassInstance`: The return type is the instance type of the provided class. 19 | If `T` cannot be resolved to an instance type (for instance, if `T` is not a constructor), then the return type defaults to `any`. 20 | 21 | ## Examples 22 | 23 | ```typescript 24 | // For use with a specific class: 25 | class MyClass { 26 | prop: number; 27 | } 28 | type MyClassInstance = ClassInstance; 29 | const instance: MyClassInstance = new MyClass(); 30 | ``` 31 | 32 | > Note: `ClassInstance` cannot guarantee the type at runtime. If you need to check the type at runtime, you will have to perform that check explicitly in your code. 33 | 34 | ## Example Implementation 35 | 36 | ```typescript 37 | import { ClassInstance } from "typescript-dev-utils"; 38 | 39 | class MyClass { 40 | constructor(public message: string) {} 41 | } 42 | 43 | function createInstance any>(Cls: T, args: ConstructorParameters): ClassInstance { 44 | return new Cls(...args) as ClassInstance; 45 | } 46 | 47 | const instance = createInstance(MyClass, ["Hello World"]); 48 | console.log(instance instanceof MyClass); // Returns: true 49 | console.log(instance.message); // Returns: "Hello World" 50 | ``` 51 | -------------------------------------------------------------------------------- /docs/ClassUtils/MethodReturnType.md: -------------------------------------------------------------------------------- 1 | # MethodReturnType 2 | `MethodReturnType` is a utility type that gets the return type of a specific method within a `T` object. It is useful when you want to work with the return type of a specific method within an object. 3 | 4 | ## Definition 5 | ```typescript 6 | export type MethodReturnType = T[K] extends (...args: any[]) => infer R ? R : any; 7 | ``` 8 | 9 | ## Type Parameters 10 | - `T`: This type parameter represents the object you are interested in. 11 | - `K`: This type parameter represents the key of the method within the `T` object whose return type you are interested in obtaining. 12 | 13 | ## Return Value 14 | - `MethodReturnType`: The return type is the return type of the method that corresponds to the `K` key within the `T` object. If the key `K` does not correspond to a method in `T`, or if the method does not have an explicit return type, the return type will be `any`. 15 | 16 | ## Example 17 | For use with a specific object and method key: 18 | ```typescript 19 | class MyClass { 20 | greet(name: string): string { 21 | return `Hello, ${name}!`; 22 | } 23 | } 24 | 25 | type MyMethodReturnType = MethodReturnType; // string. 26 | ``` 27 | 28 | ## Example Implementation 29 | ```typescript 30 | import { MethodReturnType } from "typescript-dev-utils"; 31 | import { expectType } from "tsd"; 32 | 33 | class MyClass { 34 | greet(name: string): string { 35 | return `Hello, ${name}!`; 36 | } 37 | } 38 | 39 | const myInstance = new MyClass(); 40 | 41 | const result = myInstance.greet("John"); 42 | 43 | // We expect the type of the result to be the return type of the greet method 44 | expectType>(result); 45 | expect(result).toBe("Hello, John!"); 46 | ``` 47 | 48 | ## Note 49 | `MethodReturnType` can be useful for working with the return type of specific methods. However, remember that TypeScript is a compile-time type system and cannot guarantee type consistency at run-time. -------------------------------------------------------------------------------- /docs/ClassUtils/PublicMethods.md: -------------------------------------------------------------------------------- 1 | # PublicMethods 2 | `PublicMethods` is a utility type that gets all the keys of a `T` object that correspond to public methods. It is useful when you want to work with the keys of an object that represent public methods. 3 | 4 | ## Definition 5 | ```ts 6 | export type PublicMethods = { 7 | [K in keyof T]: T[K] extends (...args: any[]) => any ? K : never; 8 | }[keyof T]; 9 | ``` 10 | 11 | ## Parameters 12 | - `T`: This type parameter represents the object you are interested in. 13 | 14 | ## Return Type 15 | - `PublicMethods`: The return type is a union type of all keys in `T` that correspond to public methods. If there are no keys that are public methods, the return type will be `never`. 16 | 17 | ## Example 18 | For use with a specific object: 19 | ```ts 20 | class MyClass { 21 | public myPublicMethod(): void { } 22 | private myPrivateMethod(): void { } 23 | } 24 | 25 | type MyPublicMethods = PublicMethods; // "myPublicMethod". 26 | ``` 27 | 28 | ## Example Implementation 29 | ```ts 30 | import { PublicMethods } from "typescript-dev-utils"; 31 | import { expectType } from "tsd"; 32 | 33 | // Function to get the public methods of an object 34 | const obtenerMetodosPublicos = (obj: T): Array> => { 35 | const keys = Object.getOwnPropertyNames(Object.getPrototypeOf(obj)).filter( 36 | key => typeof obj[key] === "function" && key !== "constructor" 37 | ) as Array>; 38 | return keys; 39 | }; 40 | 41 | // Example usage with a class 42 | class MiClase { 43 | public nombre: string = "Juan"; 44 | public apellido: string = "Perez"; 45 | 46 | public saludar() { 47 | return `Hola, mi nombre es ${this.nombre} ${this.apellido}`; 48 | } 49 | } 50 | 51 | const miObjeto = new MiClase(); 52 | 53 | const resultado = obtenerMetodosPublicos(miObjeto); 54 | 55 | // Type assertion and expectation 56 | expectType>>(resultado); 57 | expect(resultado).toEqual(["saludar"]); 58 | ``` 59 | 60 | ## Notes 61 | `PublicMethods` can be useful for working with object keys representing public methods. However, remember that TypeScript is a compile-time type system and cannot guarantee type consistency at runtime. -------------------------------------------------------------------------------- /docs/InterfaceUtils/DeepReadOnly.md: -------------------------------------------------------------------------------- 1 | # DeepReadonly 2 | `DeepReadonly` is a utility type in TypeScript that takes a `T` type and makes all of its properties (and the properties of its properties, etc.) read-only. 3 | 4 | ## Definition 5 | ```ts 6 | export type DeepReadonly = { 7 | readonly [P in keyof T]: T[P] extends object ? DeepReadonly : T[P]; 8 | }; 9 | ``` 10 | ## Parameters 11 | - `T`: This type parameter represents any type of object you wish to convert to a read-only version. 12 | 13 | ## Return Type 14 | - `DeepReadonly`: The return type is a "deep" read-only version of `T`. Each property of `T` (and subproperties, etc.) will be read-only, which means that you cannot assign new values to them after creation. 15 | 16 | ## Examples 17 | For use with a single object: 18 | ```ts 19 | type MyReadonlyObj = DeepReadonly<{ prop: number, subObj: { prop2: string } }>; 20 | const obj: MyReadonlyObj = { prop: 1, subObj: { prop2: 'test' } }; 21 | // This will give an error, since 'prop' is read-only. 22 | obj.prop = 2; 23 | ``` 24 | 25 | ## Example Implementation 26 | ```ts 27 | import { DeepReadonly } from "typescript-dev-utils"; 28 | import { ExampleObjectOne } from "@/test/utils/ExampleObjectData"; 29 | 30 | // Transforming ExampleObjectOne to a read-only version using DeepReadonly 31 | function transformToReadonly(): DeepReadonly { 32 | return ExampleObjectOne; 33 | } 34 | 35 | // Obtaining the read-only data 36 | const readonlyData = transformToReadonly(); 37 | 38 | // Accessing properties (read-only) 39 | console.log(readonlyData.user.name); // Returns: "John Doe" 40 | console.log(readonlyData.user.details.age); // Returns: 30 41 | console.log(readonlyData.user.details.address.street); // Returns: "street 123" 42 | ``` 43 | 44 | ## Notes 45 | `DeepReadonly` can be very useful for working with complex object types and ensuring immutability. It recursively makes all properties of the object and its sub-properties read-only. However, it's important to be aware that using `DeepReadonly` extensively on large objects or deeply nested structures can have a performance impact. -------------------------------------------------------------------------------- /docs/InterfaceUtils/KeysOfType.md: -------------------------------------------------------------------------------- 1 | # KeysOfType 2 | `KeysOfType` is a utility type that gets all the keys of a `T` object whose values correspond to the `U` type. It is useful when you want to work with keys of an object that have a specific value type. 3 | 4 | ## Definition 5 | ```ts 6 | export type KeysOfType = { 7 | [K in keyof T]: T[K] extends U ? K : never; 8 | }[keyof T]; 9 | ``` 10 | 11 | ## Parameters 12 | - `T`: This type parameter represents the object you are interested in. 13 | - `U`: This type parameter represents the type of value you are looking for within the `T` object. 14 | 15 | ## Return Type 16 | - `KeysOfType`: The return type is a union type of all keys in `T` whose values correspond to type `U`. If there are no keys having a value of type `U`, the return type will be `never`. 17 | 18 | ## Examples 19 | For use with a specific object and value type: 20 | ```ts 21 | type MyType = { a: number; b: string; c: number; }; 22 | type NumberKeys = KeysOfType; // 'a' | 'c' 23 | ``` 24 | 25 | ## Example Implementation 26 | ```ts 27 | import { KeysOfType } from "typescript-dev-utils"; 28 | import { expectType } from "tsd"; 29 | 30 | interface IMiInterfaz { 31 | nombre: string; 32 | edad: number; 33 | direccion: string; 34 | activo: boolean; 35 | } 36 | 37 | // Function to get keys of type string from an object 38 | const getKeysOfString = (obj: T): Array> => { 39 | const keys = (Object.keys(obj) as Array).filter( 40 | key => typeof obj[key] === 'string' 41 | ) as Array>; 42 | return keys; 43 | }; 44 | 45 | // Example usage 46 | const miObjeto: IMiInterfaz = { nombre: "Juan", edad: 30, direccion: "Calle Falsa 123", activo: true }; 47 | 48 | const resultado = getKeysOfString(miObjeto); 49 | 50 | // Type assertion and expectation 51 | expectType>>(resultado); 52 | expect(resultado).toEqual(["nombre", "direccion"]); 53 | ``` 54 | 55 | ## Notes 56 | `KeysOfType` can be useful for working with object keys that have a specific type value. However, remember that TypeScript is a compile-time type system and cannot guarantee type consistency at run-time. -------------------------------------------------------------------------------- /docs/InterfaceUtils/OmitByValueType.md: -------------------------------------------------------------------------------- 1 | # OmitByValueType 2 | `OmitByValueType` is a utility type that gets all keys of a `T` object whose values do not correspond to the `U` type. It is useful when you want to work with keys of an object that have a specific value type and exclude those that do not. 3 | 4 | ## Definition 5 | ```ts 6 | export type OmitByValueType = { 7 | [P in keyof T]: T[P] extends U ? never : P; 8 | }[keyof T]; 9 | ``` 10 | 11 | ## Parameters 12 | - `T`: This type parameter represents the object you are interested in. 13 | - `U`: This type parameter represents the type of value you are looking to exclude within the `T` object. 14 | 15 | ## Return Type 16 | - `OmitByValueType`: The return type is a union type of all keys in `T` whose values do not correspond to type `U`. If all keys have a value of type `U`, the return type will be `never`. 17 | 18 | ## Example 19 | For use with a specific object and value type: 20 | ```ts 21 | type MyType = { a: number; b: string; c: number; }; 22 | type NonNumberKeys = OmitByValueType; // 'b' 23 | ``` 24 | 25 | ## Example Implementation 26 | ```ts 27 | import { OmitByValueType } from "typescript-dev-utils"; 28 | import { expectType } from "tsd"; 29 | 30 | interface IMiInterfaz { 31 | nombre: string; 32 | edad: number; 33 | direccion: string; 34 | activo: boolean; 35 | } 36 | 37 | const getNonStringKeys = (obj: T): Array> => { 38 | const keys = (Object.keys(obj) as Array).filter( 39 | key => typeof obj[key] !== 'string' 40 | ) as Array>; 41 | return keys; 42 | }; 43 | 44 | const miObjeto: IMiInterfaz = { nombre: "Juan", edad: 30, direccion: "Calle Falsa 123", activo: true }; 45 | 46 | const resultado = getNonStringKeys(miObjeto); 47 | 48 | // Type assertion and expectation 49 | expectType>>(resultado); 50 | expect(resultado).toEqual(["edad", "activo"]); 51 | ``` 52 | 53 | ## Notes 54 | `OmitByValueType` can be useful for working with object keys that have a specific value type. However, remember that TypeScript is a compile-time type system and cannot guarantee type consistency at runtime. -------------------------------------------------------------------------------- /docs/InterfaceUtils/OverrideInterface.md: -------------------------------------------------------------------------------- 1 | # OverrideInterface 2 | `OverrideInterface` is a utility type that takes two types `T` and `U` and combines their properties. However, if `T` and `U` have properties with the same keys, the properties of `U` overwrite those of `T`. 3 | 4 | ## Definition 5 | ```ts 6 | export type OverrideInterface = Omit & U; 7 | ``` 8 | 9 | ## Parameters 10 | - `T`: This type parameter represents the first type you want to combine. 11 | - `U`: This type parameter represents the second type, whose properties will overwrite those of `T` if they have the same keys. 12 | 13 | ## Return Type 14 | - `OverrideInterface`: The return type is a combination of `T` and `U`, but with the properties of `U` overwriting those of `T` if they have the same keys. 15 | 16 | ## Examples 17 | For use with two specific interface types: 18 | ```ts 19 | interface MyFirstType { a: number; b: string; } 20 | interface MySecondType { b: number; c: boolean; } 21 | type MyOverrideType = OverrideInterface; 22 | // The resulting type is { a: number; b: number; c: boolean; } 23 | ``` 24 | 25 | ## Example Implementation 26 | ```ts 27 | import { OverrideInterface } from "typescript-dev-utils"; 28 | import { expectType } from "tsd"; 29 | 30 | interface IFuente { 31 | nombre: string; 32 | edad: number; 33 | direccion: string; 34 | } 35 | 36 | interface IOverride { 37 | nombre: string; 38 | ciudad: string; 39 | } 40 | 41 | // Function to override properties from the source interface 42 | const getDatos = (fuente: T, override: U): OverrideInterface => { 43 | return { ...fuente, ...override }; 44 | }; 45 | 46 | // Example usage 47 | const fuente: IFuente = { nombre: "Juan", edad: 30, direccion: "Calle Falsa 123" }; 48 | const override: IOverride = { nombre: "Pedro", ciudad: "Madrid" }; 49 | 50 | const resultado = getDatos(fuente, override); 51 | 52 | // Type assertion and expectation 53 | expectType>(resultado); 54 | expect(resultado).toEqual({ nombre: "Pedro", edad: 30, direccion: "Calle Falsa 123", ciudad: "Madrid" }); 55 | ``` 56 | 57 | ## Notes 58 | `OverrideInterface` can be useful for modifying existing types or for combining types with possibly matching properties.

9 | 23 | 24 | The Useful Types library is an indispensable tool for any developer who works with TypeScript on a regular basis. This library is designed to provide a wide range of common types used in everyday software development. 25 | 26 | Often, developers find themselves writing and rewriting the same types in different projects. This library aims to solve this problem by providing a complete set of well-defined and extensively tested types. 27 | 28 | The library of useful types consists of a number of type definitions ranging from the most basic to the most advanced.
