Best practices for Kong debugging + example

same here. Despite that I use ZeroBraneStudio for coding, I do not use the debugger, but use a tail on the regular logs.

for quick stuff I add debug lines like:
print(require("pl.pretty").write({..parameters here...})

For more elaborate work I temporarily insert a function like this:

--- Debug function for development purposes.
-- Will dump all passed in parameters in a pretty-printed way
-- as a `warning` log message. Includes color markers to make it stand out.
-- @param ... list of parameters to dump
local dump = function(...)
  local info = debug.getinfo(2) or {}
  local input = { n = select("#", ...), ...}
  local write = require("pl.pretty").write
  local serialized
  if input.n == 1 and type(input[1]) == "table" then
    serialized = "(" .. type(input[1]) .. "): " .. write(input[1])
  elseif input.n == 1 then
    serialized = "(" .. type(input[1]) .. "): " .. tostring(input[1]) .. "\n"
  else
    local n
    n, input.n = input.n, nil
    serialized = "(list, #" .. n .. "): " .. write(input)
  end

  ngx.log(ngx.WARN,
          "\027[31m\n",
          "function '", tostring(info.name), ":" , tostring(info.currentline),
          "' in '", tostring(info.short_src), "' wants you to know:\n",
          serialized,
          "\027[0m")
end
