Mapped Types
Configuration module for Nest framework (node.js)
Overview
The DescriptionMapped Types module for Nest is used by the @nestjs/graphql and @nestjs/swagger packages. It provides utility functions for type transformations in NestJS, making it easier to construct variants on a base entity type, such as Data Transfer Objects (DTOs). These transformations help avoid redundant code and simplify the definition of input and output interfaces within an application.
Features
- PartialType: Returns a type (class) with all properties of the input type set to optional.
- PickType: Constructs a new type (class) by selecting a set of properties from an input type.
- OmitType: Constructs a type by selecting all properties from an input type and then removing a specified set of keys.
- IntersectionType: Combines two types into a new type (class).
Summary
The DescriptionMapped Types module for Nest is a valuable tool for developers working with @nestjs/graphql and @nestjs/swagger packages. It offers utility functions like PartialType, PickType, OmitType, and IntersectionType to streamline the construction of variants on base entity types, such as Data Transfer Objects. By leveraging these type transformations, developers can reduce redundancy in their code and define input and output interfaces more efficiently within their NestJS applications.
- Nest
A progressive Node.js framework for building efficient, scalable, and enterprise-grade server-side applications with TypeScript/JavaScript.
- Eslint
ESLint is a linter for JavaScript that analyzes code to detect and report on potential problems and errors, as well as enforce consistent code style and best practices, helping developers to write cleaner, more maintainable code.
- Typescript
TypeScript is a superset of JavaScript, providing optional static typing, classes, interfaces, and other features that help developers write more maintainable and scalable code. TypeScript's static typing system can catch errors at compile-time, making it easier to build and maintain large applications.
