Express Json Validator Middleware
Express middleware for validating requests against JSON schema
Overview:
Express JSON Validator Middleware is an Express middleware designed to validate requests against JSON schemas using Ajv. It allows for expressive and standard validation of data structures, separating validation from route handlers, providing detailed error messaging, and aiding in documenting the application.
Features:
- Expressive: JSON schemas offer an expressive way to describe data structures.
- Standard: JSON schemas are portable across different languages.
- Separate validation: Avoid the need to handle request validation in route handlers.
- Error messaging: Detailed and descriptive error objects provided by Ajv.
- Documentation: JSON schemas can serve as documentation for the application.
Summary:
Express JSON Validator Middleware is a powerful tool for validating requests against JSON schemas in Express applications. It offers benefits such as expressive validation, standardization, error messaging, and improved documentation. Users can install and configure the middleware to enhance the validation process in their applications effectively.
- Express
Express.js is a simple Node.js framework for single, multi-page, and hybrid web applications.
- 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.
