Demo VisualData/Lua

There are 2 ways to use Lua.

1) perform the query directly from Lua, as follows:

local p = {}

function p.main(frame)
  -- local args = frame:getParent().args

  local ret = mw.visualdata.query( 'Book', '[[title::+]]', {'title'}, {} )

  return mw.text.jsonEncode(ret)
end

return p

Template: Template:Test Lua

Module: Module:TestLua

[{"pageid":1806,"title":"Test Book","data":{"authors":[{"first_name":"Test","last_name":"Author","name":"Test Author","email":""}],"title":"Test Book","cover":"File:"}}]

2) perform the query on a wiki article and then process the result using Lua

local p = {}

function p.main(frame)
  -- local args = frame:getParent().args
  local origArgs = (type(frame.getParent) == "function") and frame:getParent().args or frame
  local success, json = pcall(mw.text.jsonDecode, origArgs[0])

  -- do more processing here
  local ret = json

  return mw.text.jsonEncode(ret)
end


return p
