Long Polling Server

A simple long-polling server (and client) written in Lua.

source: javascript.info

Use cases:

• In environments where it is not possible to create a web server (e.g. in a Garry's Mod game), but getting "webhooks" is necessary
• As a single point of collecting webhooks, for example to get updates from all your Telegram bots with just one request. To do this, make https://api.telegram.org/bot$TOKEN/setWebhook?url=https://your.app/SomeS3cretP@th?this_key=and_value&will_be=merged_with_updates_sent_by_telegram&botname=some_id.
• Simple chat-like services implementations

Documentation:

Not ready yet. I am lazy. But if you create an issue so I can see that someone needs it, I will create code documentation instantly ⚡.

But you can look at the examples below to understand what is what. Also, in the examples there are README files with a lot of useful information.

Application examples:

• 🔥 advanced. Source code of real-working application
• simple. Simple to understand example of using the library

TODO:

• Move out redis-safe into separate repo
• Split the library and application examples into separate repos. Need for the ability to do require("kupol.server") and require("kupol.client")
• Create the mysql dataprovider, using luasocket-mysql driver
• Also create the filesystem dataprovider
