tiny-pub-sub

A pub/sub message queue server from scratch in zig, over UDP.

For development, download the SQLite amalgamation from the SQLite download page and place the sqlite.c and sqlite.h file in the server/lib/sqlite3/ folder. Then run zig build run.

Instead of also spinning up a client to test the server, you can just run in the terminal nc -u 127.0.0.1 9999 and start sending messages (starting with the prefix SND/ACK/HIS).

SND = send. ACK = acknowledge. HIS = history.

SND Here is my first message.
(server response to all subs) EVT id:1 Here is my first message.
HIS
(server response to caller) EVT id:1 Here is my first message.
ACK 1
HIS
(No response from server)

TODO:

• Some versions of a good client in different languages
• Encryption via one or more saved keys
• Hash the messages from client to verify that the server ends up getting the correct bits
• Write tests 😁✌️☮️
