Input JSON to convert it into a TypeORM schema!

- Setting up a new TypeORM project - When starting a new Node.js project and needing to define database models using TypeORM, define the database model in JSON format and use this application to automatically generate TypeORM entity classes. - Converting existing data models to TypeORM - When needing to convert existing data models defined in JSON format to TypeORM models, input the JSON data model definition to automatically generate TypeORM entities and related settings, and convert existing models to fit the TypeORM environment. - Synchronizing API documentation with TypeORM schema - When needing to synchronize data models provided in API documentation with TypeORM schema, obtain the data model in JSON format from the API documentation and use this application to convert the model into TypeORM entities to automatically update the database schema. - Automatic code generation - When needing to maintain consistency between database models and TypeORM entities in large projects, input the database structure defined in JSON format to automatically generate TypeORM entity classes, maintain code consistency, and reduce manual writing errors. - Reusing data models across projects - When needing to use common data models in multiple TypeORM projects, convert the common data model defined in JSON format into TypeORM entities to efficiently reuse the same data model across different projects.
