When you need to encapsulate JSON data returned by backend APIs into operable objects on the frontend, manually writing class definitions is both tedious and error-prone. This tool automatically parses JSON data structures and generates ES6-compliant JavaScript class code, including property declarations, constructors, and optional fromJson methods. JSON (JavaScript Object Notation) is a lightweight data-interchange format, while JavaScript classes are used to create object templates with defined structures and behaviors.
Q: What input formats does the JSON to JavaScript Class converter support?
A: It supports JSON objects or arrays that comply with the RFC 8259 standard. Date strings will be identified as string types; if you need Date objects, please modify them manually.
Q: Can the generated code be used directly in a production environment?
A: The generated code is a basic data model skeleton. You will need to add validation logic and method encapsulation based on your business requirements.
Please ensure your input JSON format is correct. Complex nested structures may generate lengthy code, which we recommend optimizing manually. The tool does not retain type information that is not present in the original JSON values; all types are inferred based on the values. Your data is processed entirely in your browser and is never sent to a server.
For API data modeling, we recommend adding data validation and serialization methods after generating the class. For example, for user data JSON, you can extend the User class by adding a getFullName() method. A typical input is {"name":"John","age":30}, and the output is a class definition containing name and age properties, supporting instantiation via new User(data).
