Create React App Officially Deprecated Amid React 19 Compatibility Issues
Create React App is officially deprecated due to React 19 issues and lack of maintenance—developers should switch to Vite or other modern alternatives.
This is a Tornado websocket backend for the Xterm.js Javascript terminal emulator library.
It evolved out of pyxterm, which was part of GraphTerm (as lineterm.py), v0.57.0 (2014-07-18), and ultimately derived from the public-domain Ajaxterm code, v0.11 (2008-11-13) (also on Github as part of QWeb).
Modules:
terminado.management
: controls launching virtual terminals,
connecting them to Tornado's event loop, and closing them down.terminado.websocket
: Provides a websocket handler for
communicating with a terminal.terminado.uimodule
: Provides a Terminal
Tornado UI
Module.JS:
terminado/_static/terminado.js
: A lightweight wrapper to set up a
term.js terminal with a websocket.Local Installation:
$ pip install -e .[test]
Usage example:
import os.path
import tornado.web
import tornado.ioloop
# This demo requires tornado_xstatic and XStatic-term.js
import tornado_xstatic
import terminado
STATIC_DIR = os.path.join(os.path.dirname(terminado.__file__), "_static")
class TerminalPageHandler(tornado.web.RequestHandler):
def get(self):
return self.render(
"termpage.html",
static=self.static_url,
xstatic=self.application.settings["xstatic_url"],
ws_url_path="/websocket",
)
if __name__ == "__main__":
term_manager = terminado.SingleTermManager(shell_command=["bash"])
handlers = [
(r"/websocket", terminado.TermSocket, {"term_manager": term_manager}),
(r"/", TerminalPageHandler),
(
r"/xstatic/(.*)",
tornado_xstatic.XStaticFileHandler,
{"allowed_modules": ["termjs"]},
),
]
app = tornado.web.Application(
handlers,
static_path=STATIC_DIR,
xstatic_url=tornado_xstatic.url_maker("/xstatic/"),
)
# Serve at http://localhost:8765/ N.B. Leaving out 'localhost' here will
# work, but it will listen on the public network interface as well.
# Given what terminado does, that would be rather a security hole.
app.listen(8765, "localhost")
try:
tornado.ioloop.IOLoop.instance().start()
finally:
term_manager.shutdown()

more examples. This is a simplified version of the single.py
demo.
Run the unit tests with:
$ pytest
