FastDepends - FastAPI Dependency Injection system extracted from FastAPI and cleared of all HTTP logic.
This is a small library which provides you with the ability to use lovely Fastapi interfaces in your own
projects or tools.
Thanks to [*fastapi*](https://fastapi.tiangolo.com/) and [*pydantic*](https://docs.pydantic.dev/) projects for this
greate functionality. This package is just a small change of the original Fastapi sources to provide DI functionality in a pyre-Python way.
Async and sync modes are both supported.
## Installation
```bash
pip install fast-depends
```
## Usage
There is no way to make Dependency Injection easier
You can use this library without any frameworks in both **sync** and **async** code.
### Async code
```python
import asyncio
from fast_depends import inject, Depends
async def dependency(a: int) -> int:
return a
@inject
async def main(
a: int,
b: int,
c: int = Depends(dependency)
) -> float:
return a + b + c
assert asyncio.run(main("1", 2)) == 4.0
```
### Sync code
```python
from fast_depends import inject, Depends
def dependency(a: int) -> int:
return a
@inject
def main(
a: int,
b: int,
c: int = Depends(dependency)
) -> float:
return a + b + c
assert main("1", 2) == 4.0
```
`@inject` decorator plays multiple roles at the same time:
* resolve *Depends* classes
* cast types according to Python annotation
* validate incoming parameters using *pydantic*
---
### Features
Synchronous code is fully supported in this package: without any `async_to_sync`, `run_sync`, `syncify` or any other tricks.
Also, *FastDepends* casts functions' return values the same way, it can be very helpful in building your own tools.
These are two main defferences from native Fastapi DI System.
---
### Custom Fields
If you wish to write your own FastAPI or another closely by architecture tool, you should define your own custom fields to specify application behavior.
Custom fields can be used to adding something specific to a function arguments (like a BackgroundTask) or parsing incoming objects special way. You able decide by own, why and how you will use these tools.
FastDepends grants you this opportunity a very intuitive and comfortable way.
```python
from fast_depends import inject
from fast_depends.library import CustomField
class Header(CustomField):
def use(self, **kwargs: AnyDict) -> AnyDict:
kwargs = super().use(**kwargs)
kwargs[self.param_name] = kwargs["headers"][self.param_name]
return kwargs
@inject
def my_func(header_field: int = Header()):
return header_field
assert my_func(
headers={ "header_field": "1" }
) == 1
```
---
### Note
Library was based on **0.95.0 FastAPI** version.
