## Usage

### Config

> The later config will override the previous one.

This table shows the predefined environment variables.

| Keyword    | Type    | Default     | Description                                                                        |
|------------|---------|-------------|------------------------------------------------------------------------------------|
| `DEBUG`    | boolean | false       | To set the logging as `DEBUG` state, you can pass `debug=True` to application too. |
| `RELOAD`   | boolean | false       | To auto reload the FastAPI application, you can pass `reload=True` to `run` too.   |
| `APP_NAME` | string  | Backend API | The application name use on FastAPI.                                               |

```python
from pathlib import Path

from api_helper.config import load_config

# Load config
load_config(Path(__file__).parent / ".env")

# Load default config in the directory (.env)
load_config(Path(__file__).parent)
```

### FastAPI example

> To config the FastAPI by env, read the [Config](#config) section.

```python
from pathlib import Path

from api_helper import FastAPI, success_response

app: FastAPI = FastAPI(base_folder=Path(__file__).parent)
# Optional to setup sentry
app.setup_sentry("sentry_dsn")


@app.get("/")
def home():
    return success_response("Hello, World!")


# Start the app and enjoy
app.run("127.0.0.1", 5000)

# Start the app with OpenAPI, for example
app.run(show_swagger=True)
```

#### Use FastAPI with auto-reload

To use the reload method, you need to pass `reload=True` and `app="main:app"` to the `run` method.  
If you don't pass them, the reload will not work. See the sample code below.

```python
from pathlib import Path

from api_helper import FastAPI

# Must declared before running into main code block
app: FastAPI = FastAPI(base_folder=Path(__file__).parent.parent)

if __name__ == "__main__":
    # Pass the app as a string to uvicorn.run to enable auto-reload
    app.run(app="test:app", reload=True)
```

#### Custom Logger Format

If you want to customize the Logger format, you can pass `log_builder` to the FastAPI object.  
The following example shows how to customize the logger format.  
See below sample for more information.

```python
from pathlib import Path

from api_helper import FastAPI
from api_helper.config import LoggerBuilder

# To customize the logger format, you can pass the log_builder to FastAPI
log_builder: LoggerBuilder = LoggerBuilder(Path(__file__).parent)
log_builder.formatters = {}  # For example, we change the formatter to empty
app: FastAPI = FastAPI(base_folder=Path(__file__).parent, log_builder=log_builder)

# Or if you prefer the default, you can extend the default formatter
# For example, you can change the root level to DEBUG with default formatter
log_builder: LoggerBuilder = LoggerBuilder(Path(__file__).parent, config={"root": {"level": "DEBUG"}})
app: FastAPI = FastAPI(base_folder=Path(__file__).parent, log_builder=log_builder)

# Or pass as parameter start with the `logging_` keyword, it will be passed to the LoggerBuilder
# It is the same as the previous example
app: FastAPI = FastAPI(base_folder=Path(__file__).parent, logging_config={"root": {"level": "DEBUG"}})
```

#### Response

> Expose the `SuccessModel` and `ErrorModel` to represent the response.

sample:

```python
from api_helper.model import SuccessModel
from api_helper import success_response
from fastapi import Response


# Basic usage
@route.get("/", response_model=SuccessModel)
def get() -> Response:
    return success_response("Hello, World!")


# If you have custom data, you can pass it to the success_response
@route.get("/", response_model=SuccessModel[list[User]])
def get() -> Response:
    return success_response(session.exec(select(User)).all())


# If you use paginate
@route.get("/items", response_model=SuccessModel[Pagination[User]])
def list_items() -> Response:
    return success_response(paginate(session=session, query=select(User)))
```

### Database

#### Alembic

> The `Alembic` class is an easy way to check Alembic status by code.  
> You can use the `Alembic` class to check the Alembic status.

properties:

- `current`: The current revision. If not current, return empty string.
- `head`: The head revision. If not head, return empty string.
- `upgradeable`: If the current is not head, return True.
- `scrip_direrctory`: The ScriptDirectory object, used by alembic.

functions:

- `get_config()`: Get the Alembic config object. You can pass it to alembic `env.py` file.
- `upgrade()`: Upgrade to the revision, if not provided, it will upgrade to the head.

#### SQLModel Pagination

> To reduce the boilerplate code, you can use the `paginate` function to get the pagination object.

parameters:

- `session`: The session object from the database.
- `query`: The query object from the database. It can use where, limit, offset, etc.
- `page`: The page number, default is 1.
- `per_page`: The number of items per page, default is 10.

sample code:

```python
from api_helper.database import paginate
from sqlmodel import SQLModel


# For example, you have a SQLModel
class User(SQLModel, table=True):
    id: int
    name: str


# You can use the paginate function to get the pagination
# The paginate function will return the pagination object
pagination = paginate(session=session, query=select(User))

# You will get something like this
{
    "items": [],
    "pagination": {
        "total": 0,
        "page": 1,
        "pages": 1,
        "per_page": 10,
        "prev": None,
        "next": None,
    }
}
```

## Changelogs
