------------
-- A module which shows different ways to manage static game data within the server.
-- @module static

--- Option 1
-- Load all game state via a http hook which can be called after server start.
-- expected input:
-- {"skills": [{"context": {"bucket": "b", "collection": "skills", "record": "skill1"}}, ...]}
-- usage:
-- curl -X POST "http://127.0.0.1:7350/runtime/static.setup?key=defaultkey" \
--      -d @static.json \
--      -H 'Content-Type: application/json'
--      -H 'Accept: application/json'
nk.register_http(function(context, payload)
  local skills = assert(payload.skills, "'skills' field required.")
  local records = {}
  for i, v in ipairs(skills)
  do
    local context = assert(v.context, "'context' field required.")
    local record = {
      Bucket = assert(context.bucket, "'bucket' field required."),
      Collection = assert(context.collection, "'collection' field required."),
      Record = assert(context.record, "'record' field required."),
      Value = assert(v.value, "'value' field required."),
      PermissionRead = 2,
      PermissionWrite = 0
    }
    table.insert(records, record)
  end
  nk.storage_write(records)
end, "static.setup")

--- Option 2
-- Manage the game state directly as code which is loaded at server start.
do
  local records = {
    -- Skills
    {
      Bucket = "b", Collection = "skills", Record = "fireball", PermissionRead = 2, PermissionWrite = 0,

        element = 0, -- fire(0), water(1), earth(2), wind(3)
        base_damage = 20
      }
    }, {
