# SlowApi
|
|
|
|
A rate limiting library for Starlette and FastAPI adapted from [flask-limiter](http://github.com/alisaifee/flask-limiter).
|
|
|
|
Note: this is alpha quality code still, the API may change, and things may fall apart while you try it.
|
|
|
|
The documentation is on [read the docs](https://slowapi.readthedocs.io/en/latest/).
|
|
|
|
# Quick start
|
|
|
|
## Installation
|
|
|
|
`slowapi` is available from [pypi](https://pypi.org/project/slowapi/) so you can install it as usual:
|
|
|
|
```
|
|
$ pip install slowapi
|
|
```
|
|
|
|
# Features
|
|
|
|
Most feature are coming from (will come from) FlaskLimiter and the underlying [limits](https://limits.readthedocs.io/).
|
|
|
|
Supported now:
|
|
|
|
- Single and multiple `limit` decorator on endpoint functions to apply limits
|
|
- redis, memcached and memory backends to track your limits (memory as a fallback)
|
|
- support for sync and async HTTP endpoints
|
|
- Support for shared limits across a set of routes
|
|
|
|
|
|
# Limitations and known issues
|
|
|
|
* The `request` argument must be explicitly passed to your endpoint, or `slowapi` won't be able to hook into it. In other words, write:
|
|
|
|
```python
|
|
@limiter.limit("5/minute")
|
|
async def myendpoint(request: Request)
|
|
pass
|
|
```
|
|
|
|
and not:
|
|
|
|
```python
|
|
@limiter.limit("5/minute")
|
|
async def myendpoint()
|
|
pass
|
|
```
|
|
|
|
* `websocket` endpoints are not supported yet.

# Credits
|
|
|
|
Credits go to [flask-limiter](https://github.com/alisaifee/flask-limiter) of which SlowApi is a (still partial) adaptation to Starlette and FastAPI.
|
|
It's also important to mention that the actual rate limiting work is done by [limits](https://github.com/alisaifee/limits/), `slowapi` is just a wrapper around it.
