Code Generation

APiGen's core strength lies in its ability to generate production-ready code from database schemas or OpenAPI specifications.

Supported Inputs

• SQL Schema: CREATE TABLE statements (PostgreSQL, MySQL, MariaDB, SQL Server, Oracle, H2).
• OpenAPI / Swagger: YAML or JSON specifications (v3.0+).
• JDL (JHipster Domain Language): Coming soon.

Generation Process

1. Parsing: The input is parsed into an internal AST (Abstract Syntax Tree).
2. Enrichment: Metadata is added (types, relationships, validation).
3. Template Rendering: Jinja2/Mustache templates are rendered for the target language.
4. Post-Processing: Code formatting and optimization.

Configuration

Configuration is handled via apigen.yml or CLI arguments.
