# goit_python_web_hw_05

Домашнє завадння 05.

1. Консольний застосунок / Модуль запиту курсу валют - hw_05/exchange.py
2. Консольний застосунок / WebSocket Server - hw_05/server_websoket.py
3. Консольний застосунок / WebSocket Client - hw_05/client_websoket.py
4. Консольний застосунок / Web Server aiohttp - hw_05/server_http_async.py
5. Консольний застосунок / Web Server HTTPServer - hw_05/server_http_sync.py
6. HTML WebSocket Client на JavaScript - html/index.html
7. WebSocket Server зберігає протоколи запитів до файлу logs/server_socket.log
8. Консольний застосунок - exchange_cli.
- Встановлленя pip install .
- Запсуск з консолі с описом команд: exchange_cli -h
9. Docker.
- Збирання образу: scripts/docker_build_image.cmd
- Всі серевери заускаються у одному контейнері: scripts/docker_run.cmd
- Доступ за http://localhost:8000, сокет сервер: ws://localhost:8080
- Образ є тут: https://hub.docker.com/r/lexxai/web_hw_05
10. WebSocket Session ID. Ліміти на кількість підключень від одного клієнта, та в ціломму на систему.
11. Система кешування списуку доступних валют. І його оновленння. Файл. logs\currency.dat
