NGschema

NGSchema is a JavaScript library designed for defining and validating data structures. It allows developers to create schemas that describe the expected format and types of data, ensuring that data conforms to a predefined structure. This is particularly useful in applications dealing with complex data, such as those involving APIs, configurations, or user input.

The primary function of NGSchema is to provide a declarative way to define these data structures. Developers can specify fields, their data types (strings, numbers, booleans, arrays, objects, etc.), and constraints such as required fields, minimum/maximum values, or regular expression patterns. Once a schema is defined, NGSchema can be used to validate incoming data against this schema. If the data does not meet the schema's requirements, NGSchema will report the validation errors, typically indicating which parts of the data are invalid and why.

NGSchema aims to simplify data management and reduce the likelihood of runtime errors caused by malformed data. By catching these issues early in the development process or at the point of data entry, it contributes to more robust and reliable software. The library is often used in conjunction with frontend frameworks, but it can be utilized in any JavaScript environment where data validation is necessary. Its straightforward syntax and clear error reporting make it an accessible tool for developers of varying experience levels.
