Luadata by Example: Nested Tables

Lua tables can contain other tables, forming nested structures. These become nested JSON objects.

lua

config = {
    ["host"] = "localhost",
    ["port"] = 8080,
    ["options"] = {
        ["debug"] = true,
        ["timeout"] = 30,
    },
}

output

{
  "config": {
    "host": "localhost",
    "port": 8080,
    "options": {
      "debug": true,
      "timeout": 30
    }
  }
}

Table keys can be bracketed strings like ["host"], bracketed integers like [1], or even bracketed booleans and floats. Regardless of the original key type in Lua, all keys become strings in JSON since that is all JSON supports. The nesting depth is unlimited (well, aside from your available memory).

This is common in SavedVariables files where addons store deeply nested configuration and state data.
