# FastAPI Code Generator
## Overview
Generates FastAPI application code from API path, task name, JSON schema path, and Jinja2 prompt template. Also creates a `models.py` file for Pydantic models.
## Dependencies
- FastAPI
- Pydantic
- Jinja2
- datamodel-code-generator
## Functions
### `create_app(api_path: str, task_name: str, json_schema_path: str, prompt_template: str) -> str`
Main function to generate FastAPI application code.
## Usage
Run the script with required parameters.
Example:
```python
fastapi_code = create_app(
api_path="/api/v1/extract_person",
task_name="extract_person",
json_schema_path="./input.json",
prompt_template="Extract the person from the following: {{biography}}",
)
```
Outputs FastAPI application code to `./run.py` and a Pydantic model to `./models.py`.
