# fastapi-depends
You can use your FastAPI dependencies not only in FastAPI applications
[PYPI](https://pypi.org/project/fastapi-depends/)
## Install
pip
```bash
pip install fastapi-depends
```
poetry
```bash
poetry add fastapi-depends
```
## Usage
### Simple
Simple example for calling dependencies, without binding to `fastapi.Request` object
```python
import asyncio
from fastapi import Depends
from fastapi_depends import inject
async def str_dep():
return "str_dep"
@inject
async def main(pos_value: str, regular_value: str, str_dep=Depends(str_dep)):
return (pos_value, regular_value, str_dep)
if __name__ == "__main__":
result = asyncio.run(main("pos_value", regular_value="regular_value"))
print(f"{result=}")
```
### With your application
Example of getting a `fastapi.Request` object with one property `app`
```python
import asyncio
from fastapi import Depends, Request
from fastapi_depends import DepContainer
container = DepContainer()
async def str_dep(request: Request):
return request.app.app_value
@container.inject
async def main(pos_value: str, regular_value: str, str_dep=Depends(str_dep)):
return (pos_value, regular_value, str_dep)
class MyApp:
def __init__(self, app_value):
self.app_value = app_value
app = MyApp(app_value="app_value")
container.setup_app(app)
if __name__ == "__main__":
result = asyncio.run(main("pos_value", regular_value="regular_value"))
print(f"{result=}")
```
### Register the method in your application
An example similar to the previous one, but only for a method you can specify a key with which it will be written in `DepContainer.callback_map`
```python
import asyncio
from fastapi import Depends, Request
from fastapi_depends import DepContainer
async def str_dep(request: Request):
return request.app.app_value
container = DepContainer()
@container.register("my_key")
async def main(pos_value: str, regular_value: str, str_dep=Depends(str_dep)):
return (pos_value, regular_value, str_dep)
class MyApp:
def __init__(self, app_value):
self.app_value = app_value
app = MyApp(app_value="app_value")
container.setup_app(app)
if __name__ == "__main__":
result = asyncio.run(container.callback_map["my_key"]("pos_value", regular_value="regular_value"))
print(f"{result=}")
```
