# FastAPI Feature Flags
Very simple implementation of feature flags for FastAPI.
- Minimum configuration required
- No unnecessary dependencies
- Does its job
## Installing
To install the package from pip, first run:
```bash
pip install fastapi-featureflags
```
## Usage
A simple example of feature flags:
```python
from fastapi_featureflags import FeatureFlags, feature_flag, feature_enabled
FeatureFlags(conf_from_url="https://pastebin.com/raw/4Ai3j2DC")
print("Enabled Features:", FeatureFlags.get_features())
@feature_flag("web_1")
def web_1_enabled():
print("Feature Should be enabled: web_1")
web_1_enabled()
if feature_enabled("web_2"):
print("Feature Should be disabled: web_2")
```
You can get FF (feature flags) from a **File**, **URL**, **Dictionary or ENV Variables**:
```python
FeatureFlags.load_conf_from_url("https://pastebin.com/raw/4Ai3j2DC")
FeatureFlags.load_conf_from_json("tests/features.json")
FeatureFlags.load_conf_from_dict({"web_1": True, "web_2": False})
FeatureFlags.reload_feature_flags()
```
There is also a handler that recognizes if the "@feature_flag" wrapper is used and the flag is not registered in the config.
This way you can also use FF at runtime. Defaults to False, so it's safer if you forget the feature flag in the code.
Function `get_features` returns a list of all registered FF
You can enable or disable functions on the fly with `enable_feature` or `enable_feature`
When needed you can reload all feature flags with `reload_feature_flags`,
this is useful when you want to read and change features from URL.
All unregistered or on-the-fly created FF, that are not in the configuration will be omitted.
For non-production testing, a router is available,
so you can see the paths in swagger-ui docs.
Use `include_in_schema=False` when defining the router for public deployments
```python
from fastapi_featureflags import router as ff_router
app.include_router(ff_router, prefix="/ff", tags=["FeatureFlags"])
```
