htagweb 0.4.0

It's a robust webserver (http/ws) for hosting htag apps on the web (a process by user)

htagweb

This "htagweb" module provides two htag's "runners":

• WebServer : for http only exchanges
• WebServerWS : for http/ws exchanges (first rendering is on http)

Theses runners are a lot more complete than the defaults ones (WebHTTP & WebWS, provided nativly with htag) If you want to expose your HTag apps on the web : they are the only real/official solutions. Theses are a lot robust and IRL tested.

• based on starlette
• compatible with uvloop !!!
• compatible with multiple gunicorn webworkers !!!
• works on gnu/linux or windows !
• Each user has its own process (for session, and htag app)
• real starlette session available (in htag instance, and starlette request)
• compatible with oauth2 authent ( authlib )
• real process managments (interactions timeout, process expirations, ...)
• NOT READY YET parano mode (can aes encrypt all communications between client & server ... to avoid mitm'proxies)

But be aware : it's production ready (at least, for me). It may not be free of bugs or security holes: USE AT YOUR OWN RISK. Htag and this module are youngs, and not widely tested (by experts/hackers). But due to the nature of htag, and theses runners, the risk may be minimal (only DoS), stealing datas may not be possible.

The concepts are the same :

• one user can run only one instance of an htag app at one time (like in desktop mode).
• All user processes are destroyed, after an inactivity timeout (not like in desktop mode, to preserve healthy of the webserver)
• the "session" live as long as the server live (may not be a problem on many hosting service (where they shutdown the server after inactivities))

architecture

Here is a rapid map ;-)

Roadmap / futur

• ? replace starlette by fastapi ?
• better logging !!!!
• more parameters (session size, etc ...)
• parano mode
• perhaps a bi-modal version (use ws, and fallback to http when ws com error)

Examples

A "hello world" could be :

from htag import Tag

class App(Tag.div):
    def init(self):
        self+= "hello world"

from htagweb import WebServer # or WebServerWS
WebServer( App ).run()

or, with gunicorn (in a server.py file):

from htag import Tag

class App(Tag.div):
    def init(self):
        self+= "hello world"

from htagweb import WebServer # or WebServerWS
app=WebServer( App )

and run server :

gunicorn -w 4 -k uvicorn.workers.UvicornH11Worker -b localhost:8000 --preload server:app
