I call it Chatfairy. With only 115 locs in a singel file, Chatfairy support: - user authentication - multiple users chat simultaneously - online/offline notification - route protection https://github.com/yuxiaoy1/chatfairy/assets/24974936/13186e61-1082-41c3-aa16-250b58572975 You can clone this repo and run `pip install flask && flask run`, then open `http://127.0.0.1:5000` to play with Chatfairy. ================================================ FILE: app.py ================================================ from functools import wraps from flask import ( Flask, json, redirect, render_template, request, session, url_for, ) app = Flask(__name__) app.secret_key = "secret" messages = [] def send_message(message): messages.append(message) def login_required(func): @wraps(func) def inner(*args, **kwargs): if "username" not in session: return redirect(url_for("login")) return func(*args, **kwargs) return inner @app.get("/") @login_required def index(): return render_template("index.html", username=session["username"]) @app.route("/login", methods=["GET", "POST"]) def login(): if "username" in session: return redirect(url_for("index")) if request.method == "POST": username = request.form["username"] session["username"] = username send_message( { "username": username, "message": f"{username} has joined.", "type": "auth", }, ) return redirect(url_for("index")) return render_template("login.html") @app.get("/logout") def logout(): if "username" in session: send_message( { "username": session["username"], "message": f"{session['username']} has left.", "type": "auth", } ) session.pop("username") return redirect(url_for("index")) @app.get("/events") @login_required def events(): def generate_response(): while True: for message in messages: yield f"data: {json.dumps(message)}\n\n" messages.clear() return app.response_class(generate_response(), mimetype="text/event-stream") @app.post("/message") @login_required def message(): username = session["username"] message = request.json["message"] send_message({"username": username, "message": message}) return "OK" ================================================ FILE: templates/base.html ================================================ Chatfairy
