This is a series of examples that explore Lua + Nginx via Openresty.
The goal is to demonstrate a basic webapp that processes JSON POSTs over HTTP via a message queue and data processing sink, eventually storing those messages in a Postgres database.
See dev-notes.md for the juicy details that steps through each of the examples.
After drawing up a basic design to implement for the demo, I wrote out a list of topics that I would need to sort out as a Lua/Openresty newb.
These exercises encompass:
- 01-hello-world-html
- 02-hello-world-json
- 03-echo-post-json
- 04-write-to-postgres
- 05-dynamic-db-connection-info
- 06-connect-to-redis
- 07-redis-data-sink
- 08-limit-http-methods
- 09-batch-read-from-postgres
- 10-basic-http-client
- 11-batch-submit-posts
- stand-alone-lua-image
See demo/README.md for more details on running the POST processing, message
queue demo.
