Launch a WSGI or ASGI Application in a background thread with werkzeug or uvicorn.
Project description
⚙️ Server Thread
Launch a WSGI or ASGI Application in a background thread with werkzeug or uvicorn.
This application was created for localtileserver
and provides the basis for how it can launch an image tile server as a
background thread for visualizing data in Jupyter notebooks.
While this may not be a widely applicable library, it is useful for a few Python packages I have created that require a background service.
🚀 Usage
Use the ServerThread
with any WSGI or ASGI Application.
Start by creating a application (this can be a flask app or a simple app like below):
# Create some WSGI Application
from werkzeug import Request, Response
@Request.application
def app(request):
return Response("howdy", 200)
Then launch the app with the ServerThread
class:
import requests
from server_thread import ServerThread
# Launch app in a background thread
server = ServerThread(app)
# Perform requests against the server without blocking
requests.get(f"http://{server.host}:{server.port}/").raise_for_status()
⬇️ Installation
Get started with server-thread
to create applications that require a
WSGIApplication in the background.
🐍 Installing with conda
Conda makes managing server-thread
's dependencies across platforms quite
easy and this is the recommended method to install:
conda install -c conda-forge server-thread
🎡 Installing with pip
If you prefer pip, then you can install from PyPI: https://pypi-hypernode.com/project/server-thread/
