HowTO

Here's a very basic website sketch that uses some webb features.

Create a file nginx-server.conf and type in it:

listen 127.0.0.1:8882;
set $main_module "main";   # runs main.lua for every url
set $hide_errors true;     # hide errors when crashing

Type ./ngx-start then check http://127.0.0.1:8882.

You should get a 500 error because main.lua (our main file) is missing.

main.lua

require'webbjs'    -- required, obviously
require'query'     -- if using mysql
require'sendmail'  -- if sending mail

require'secrets'   -- secrets.lua file, see below
