Converting FiveM Scripts: ESX, QBCore & QBOX Framework Guide

Introduction to This is a code‑first, no‑fluff easy converting FiveM

This is a code‑first, no‑fluff easy converting FiveM scripts guide that shows you exactly how to Convert FiveM Scripts between ESX, QBCore, QBOX (qbx_core), and framework‑agnostic (standalone) setups. You’ll get tri‑way API mappings, adapter code, SQL migration steps (mysql‑async → oxmysql), QBOX specifics, testing checklists, and production hardening tips.

---

TL;DR — Migration in 10 Steps

1. Snapshot & staging: Back up DB/files. Spin up a local test server with the target framework.
2. Identify dependencies: inventory, target, menu/UI, callbacks, DB layer, core access.
3. Pin versions & order: oxmysql → ox_lib → framework (es_extended / qb-core / qbx_core) → your resources.
4. Read the code path: Find all player, money, job/duty, inventory, callback/event, and DB calls.
5. Map APIs: Use the Rosetta tables below to map ESX ↔ QBCore ↔ QBOX.
6. Bridge it: Add a bridge.lua adapter that auto‑detects the framework and normalizes calls.
7. Convert callbacks: ESX/QB callbacks → QBOX/ox_lib lib.callback.* when needed.
8. Migrate DB: Move identifiers, accounts, items, vehicles; switch to oxmysql *.await style.
9. Harden events: Validate source, bounds, groups/jobs, ownership; never trust client.
10. QA & release: Run the checklists; tag, changelog, and rollback plan.

1) Frameworks 101: ESX vs QBCore vs QBOX vs Standalone

Architectural overview

Category

ESX

QBCore

QBOX

Architecture / Core Access

exports['es_extended']:getSharedObject() → ESX

exports['qb-core']:GetCoreObject() → QBCore

No global core object; use exports.qbx_core:* for player, groups, and notifications

Player Object

ESX.GetPlayerFromId(src) → xPlayer

QBCore.Functions.GetPlayer(src) → Player

exports.qbx_core:GetPlayer(src) → Player with PlayerData

Identifiers

Historically identifier (license/steam)

citizenid as primary key

citizenid as primary key

Money Handling

xPlayer.addMoney() / \addAccountMoney(‘bank’

‘black_money’)\

\Player.Functions.AddMoney(‘cash’

Jobs & Duty

xPlayer.job.name, .job.grade

Player.PlayerData.job.name, .grade.level, OnDuty

Job/group helpers via exports.qbx_core:* (group checks, duty setters)

Inventory

ESX default / `ox_inventory` / `qb-inventory` (recommended: `ox_inventory`)

qb-inventory / ox_inventory

ox_inventory recommended

Callbacks

ESX.RegisterServerCallback / ESX.TriggerServerCallback

QBCore.Functions.CreateCallback / TriggerCallback

Prefer ox_lib callbacks (lib.callback.register/await) or QBOX exports

Database Layer

Old: mysql-async → Now: oxmysql (MySQL.query.await, MySQL.update.await)

oxmysql

oxmysql

UI – Notifications

ESX Notify

QB Notify

QBOX notify helpers or lib.notify

UI – Menus

esx_menu_default / ox_lib:registerContext

qb-menu / ox_lib:registerContext

ox_lib:registerContext / lib.inputDialog

UI – Target System

esx_target / ox_target

qb-target / ox_target

ox_target recommended

Where QBOX differs

• Resource name and exports: qbx_core (no GetCoreObject).
• Leans on ox_lib (callbacks, notify) and oxmysql by default.
• Built‑ins for multicharacter/queue/groups; opinionated helpers for jobs/duty.

---

2) Preflight: Environment & Tooling

• Server: current FXServer artifacts, Lua 5.4, CFX ensure order
• Order: ensure oxmysql → ensure ox_lib → ensure framework → ensure yourResource
• Editor: VS Code + Lua LS, stylua; optional ripgrep for quick pattern scans
• Test setup: clean database snapshot; verbose logging; small seeded data set
• Search patterns you’ll use:

  • ESX\. xPlayer\. QBCore\. PlayerData qbx_core exports\.ox_inventory mysql%-async MySQL\.

        ## 4) Tutorial A — ESX → QBCore (Hands‑on)

Goal: Convert a simple shop resource from ESX to QBCore.

Step 1 — Dependencies

• Ensure oxmysql, ox_lib, qb-core are started.
• If the script uses ESX inventory, migrate to ox_inventory (recommended) or map to QB inventory.

Step 2 — Detect framework & add a bridge

Create bridge.lua to normalize players/money/inventory:

-- bridge.lua (ESX/QB/QBOX adapter)
local M = {}
local fw

CreateThread(function()
  if GetResourceState('qbx_core') == 'started' then
    fw = 'qbx'
  elseif GetResourceState('qb-core') == 'started' then
    fw = 'qb'
  elseif GetResourceState('es_extended') == 'started' then
    fw = 'esx'
  else
    fw = 'none'
  end
end)

function M.getFramework()
  return fw
end

function M.getPlayer(src)
  if fw == 'qbx' then
    return exports.qbx_core:GetPlayer(src)
  elseif fw == 'qb' then
    return exports['qb-core']:GetCoreObject().Functions.GetPlayer(src)
  elseif fw == 'esx' then
    return exports['es_extended']:getSharedObject().GetPlayerFromId(src)
  end
end

local function saveQbox(src)
  if fw == 'qbx' and exports.qbx_core and exports.qbx_core.Save then
    exports.qbx_core:Save(src)
  end
end

function M.addMoney(src, account, amount)
  local p = M.getPlayer(src)
  if not p or type(amount) ~= 'number' then return false end
  if fw == 'qb' then
    return p.Functions.AddMoney(account, amount)
  elseif fw == 'esx' then
    if account == 'cash' then
      return p.addMoney(amount)
    elseif account == 'bank' then
      return p.addAccountMoney('bank', amount)
    elseif account == 'black' or account == 'black_money' then
      return p.addAccountMoney('black_money', amount)
    end
  elseif fw == 'qbx' then
    local money = p.PlayerData and p.PlayerData.money or {}
    account = account == 'black' and 'crypto' or account -- example mapping
    money[account] = (money[account] or 0) + amount
    saveQbox(src)
    return true
  end
  return false
end

function M.removeMoney(src, account, amount)
  return M.addMoney(src, account, -math.abs(amount))
end

function M.addItem(src, name, count, meta)
  if GetResourceState('ox_inventory') == 'started' then
    return exports.ox_inventory:AddItem(src, name, count, meta)
  elseif fw == 'qb' then
    return exports['qb-inventory']:AddItem(src, name, count, false, meta)
  elseif fw == 'esx' then
    local p = M.getPlayer(src)
    return p and p.addInventoryItem(name, count)
  elseif fw == 'qbx' then
    return exports.ox_inventory:AddItem(src, name, count, meta)
  end
end

function M.notify(src, msg, ntype)
  if fw == 'qb' then
    TriggerClientEvent('QBCore:Notify', src, msg, ntype or 'primary')
  elseif fw == 'esx' then
    TriggerClientEvent('esx:showNotification', src, msg)
  elseif fw == 'qbx' then
    if exports.qbx_core and exports.qbx_core.Notify then
      exports.qbx_core:Notify(src, msg, ntype or 'info')
    else
      lib.notify(src, { title = 'Notice', description = msg })
    end
  else
    print(('notify(%s): %s'):format(src, msg))
  end
end

return M

Step 3 — Convert callbacks

• ESX → QB: replace ESX.RegisterServerCallback with QBCore.Functions.CreateCallback.
• Client uses QBCore.Functions.TriggerCallback.

-- server.lua (callback)
local bridge = require 'bridge'

local function getPrice(item)
  return 100
end

if GetResourceState('qb-core') == 'started' then
  local QBCore = exports['qb-core']:GetCoreObject()
  QBCore.Functions.CreateCallback('shop:getPrice', function(source, cb, item)
    cb(getPrice(item))
  end)
else
  -- fallback for QBOX/ESX via ox_lib
  lib.callback.register('shop:getPrice', function(source, item)
    return getPrice(item)
  end)
end

-- client.lua (callback)
if GetResourceState('qb-core') == 'started' then
  local QBCore = exports['qb-core']:GetCoreObject()
  QBCore.Functions.TriggerCallback('shop:getPrice', function(price)
    print('price', price)
  end, 'bread')
else
  local price = lib.callback.await('shop:getPrice', false, 'bread')
  print('price', price)
end

Step 4 — Money & inventory paths

• Replace xPlayer.addAccountMoney with Player.Functions.AddMoney (for QB) or adapter.
• Standardize all inventory changes through the adapter.

        ### Step 5 — Events (server‑side security)

RegisterNetEvent('shop:buy', function(item, amount)
  local src = source
  if type(item) ~= 'string' or type(amount) ~= 'number' then return end
  if amount < 1 or amount > 10 then return end

  local p = bridge.getPlayer(src)
  if not p then return end

  local price = 100 * amount
  if not bridge.removeMoney(src, 'cash', price) then return end
  bridge.addItem(src, item, amount)
  bridge.notify(src, ('Bought %dx %s'):format(amount, item), 'success')
end)

        ### Step 6 — DB migration (identifiers, accounts)

• Create a crosswalk id_map(identifier, citizenid).
• Populate citizenid for QB from ESX users table via rule of choice (existing column or generated).

-- Example: create crosswalk and backfill (customize to your schema)
CREATE TABLE IF NOT EXISTS id_map (
  identifier VARCHAR(64) PRIMARY KEY,
  citizenid  VARCHAR(64) NOT NULL UNIQUE
);

-- Suppose you generated new citizenids and stored them earlier
INSERT IGNORE INTO id_map(identifier, citizenid)
SELECT u.identifier, u.citizenid FROM users u WHERE u.citizenid IS NOT NULL;

mysql‑async → oxmysql

mysql‑async → oxmysql

-- before (mysql-async)
MySQL.Async.fetchAll('SELECT * FROM users WHERE identifier = @id', {['@id'] = identifier}, function(rows) ... end)

-- after (oxmysql)
local rows = MySQL.query.await('SELECT * FROM users WHERE identifier = ?', { identifier })

Step 7 — QA

• Spawn items, buy/sell, ensure balances change correctly.
• Verify callbacks return under load.
• Check that inventory metadata is preserved.

---

        ## 5) Tutorial B — QBCore → ESX (Hands‑on)

Key caveats:

• ESX uses accounts for bank/black_money. Port QB’s dirty‑money item (if used) to ESX account or keep it as an item.
• Job schema differs (grade vs level). Map carefully.

Example: Money mapping via adapter

-- in bridge.lua, when fw == 'esx'
function M.qbToEsxMoney(account)
  if account == 'cash' then return 'cash' end
  if account == 'bank' then return 'bank' end
  if account == 'black' or account == 'black_money' then return 'black_money' end
  return account
end

        ### Example: Callback conversion (server)

if GetResourceState('es_extended') == 'started' then
  local ESX = exports['es_extended']:getSharedObject()
  ESX.RegisterServerCallback('garage:getVehicles', function(source, cb)
    local src = source
    local p = bridge.getPlayer(src)
    local rows = MySQL.query.await('SELECT * FROM owned_vehicles WHERE owner = ?', { p.identifier })
    cb(rows)
  end)
end

Testing checklist

• Job set/promotions persist.
• Bank/dirty balances mutate as expected.
• Vehicle ownership and plate formats validated.

---

        ## 6) Tutorial C — QBCore ↔ QBOX (Hands‑on)

QBCore → QBOX

• Replace QBCore.Functions.* with exports.qbx_core:* or ox_lib callbacks.
• Player: QBCore.Functions.GetPlayer(src) → exports.qbx_core:GetPlayer(src).
• Notify: QBCore.Functions.Notify → exports.qbx_core:Notify or lib.notify.
• Duty/groups: use QBOX exports (SetJobDuty, HasGroup, etc.).

QBOX → QBCore

• Replace exports.qbx_core:* with QBCore.Functions.* equivalents or your adapter.
• Reintroduce QB callbacks and menu/target equivalents as needed.

Before/After snippets

-- Before (QB notify)
QBCore.Functions.Notify('Hello', 'success')

-- After (QBOX)
exports.qbx_core:Notify(source, 'Hello', 'success')
-- or
lib.notify(source, { title = 'Hello', description = 'Welcome', type = 'success' })

-- Before (QB get player)
local Player = QBCore.Functions.GetPlayer(src)

-- After (QBOX)
local Player = exports.qbx_core:GetPlayer(src)

---

        ## 7) Tutorial D — Framework → Standalone with Adapters

Write your scripts once and run them anywhere:

• Create a bridge exposing a stable API: getPlayer, getIdentifier, add/removeMoney, add/removeItem, notify, hasGroup, onDuty, callbacks wrapper.
• Detect framework at runtime (qbx_core → qb-core → es_extended → none).
• Use ox_lib for callbacks and notifications when no direct framework helper exists.

Minimal standalone fallback

-- when fw == 'none'
function M.getPlayer(src)
  -- implement a minimal table or reject actions gracefully
  return { id = src }
end

function M.notify(src, msg)
  print(('notify(%s): %s'):format(src, msg))
end

---

        ## 8) Performance & Security (Production Hardening)
        
        ### Server‑side validation (never trust client)

• Validate types and bounds on every event.
• Check ownership, cooldowns, distance (if relevant), job/group.
• Ensure money can’t go negative; clamp amounts.
• Compare price server‑side; don’t accept client‑provided totals.

Event structure

• Use one server event per action; do not expose raw inventory/money functions to clients.
• Prefer callbacks for request/response flows.

DB & performance

• Switch to oxmysql await APIs; batch writes; avoid per‑tick queries.
• Index frequently queried columns (citizenid, identifier, plate).
• Cache config/price lists in memory; export them to clients once, then diff on change.
• Use GlobalState sparingly; avoid hot‑loop updates.

---

        ## 9) Common Pitfalls & Debugging Playbook

• Assuming GetCoreObject exists on QBOX → it doesn’t; use exports.qbx_core:*.
• Callbacks never return after migrating to QBOX → ESX/QB callbacks aren’t registered; switch to lib.callback.register/await.
• Dirty money semantics differ → decide item vs account vs alt wallet and standardize in your adapter.
• Mixed inventory assumptions → normalize on ox_inventory.
• Start order issues → oxmysql → ox_lib → framework → your resources.
• Vehicle metadata drift → ensure JSON columns and plate formats match target framework.

        ## 10) fxmanifest.lua Best Practices

fx_version 'cerulean'
game 'gta5'

lua54 'yes'

shared_scripts {
  '@ox_lib/init.lua',
  'bridge.lua',
  'config.lua'
}
client_scripts {
  'client/*.lua'
}
server_scripts {
  '@oxmysql/lib/MySQL.lua',
  'server/*.lua'
}

escrow_ignore {
  'bridge.lua', 'config.lua'
}

-- dependencies (pick what you use): ox_lib, oxmysql, ox_inventory, qb-core OR qbx_core OR es_extended

• Declare Lua 5.4 (lua54 'yes').
• Keep escrow_ignore minimal; never attempt escrow bypass.

---

        ## 11) Data Migration: SQL Snippets (Examples)

Adjust table/column names to your schema

Adjust table/column names to your schema. Always run on a copy first.

Identifiers: ESX → QB/QBOX

-- Add citizenid to ESX users if missing
ALTER TABLE users ADD COLUMN IF NOT EXISTS citizenid VARCHAR(64);

-- Populate using a deterministic generator or an existing column
UPDATE users SET citizenid = LOWER(SUBSTRING(MD5(CONCAT(identifier,'-QB')),1,10))
WHERE citizenid IS NULL;

-- Create crosswalk
CREATE TABLE IF NOT EXISTS id_map (
  identifier VARCHAR(64) PRIMARY KEY,
  citizenid  VARCHAR(64) NOT NULL UNIQUE
);
INSERT IGNORE INTO id_map(identifier, citizenid)
SELECT identifier, citizenid FROM users WHERE citizenid IS NOT NULL;

Accounts/Money

-- Example: convert ESX bank balances to QB money table (if your QB schema stores it separately)
INSERT INTO player_money (citizenid, account, amount)
SELECT m.citizenid, 'bank', a.money
FROM (
  SELECT u.citizenid, SUM(CASE WHEN account = 'bank' THEN money ELSE 0 END) AS money
  FROM user_accounts ua
  JOIN users u ON u.identifier = ua.identifier
  GROUP BY u.citizenid
) a
JOIN users m ON m.citizenid = a.citizenid
ON DUPLICATE KEY UPDATE amount = VALUES(amount);

Vehicles

-- Normalize plates to target format (example: 8 chars upper)
UPDATE owned_vehicles SET plate = UPPER(LEFT(plate,8));

-- Ensure JSON metadata columns are valid
UPDATE owned_vehicles SET mods = JSON_MERGE_PATCH('{}', mods) WHERE JSON_VALID(mods) = 0;

---

        ## 12) Adapters You Can Reuse (Starter)

Drop this into bridge.lua and expand per your needs. It auto‑detects ESX/QB/QBOX and exposes a stable API.

local M = {}
local fw = 'none'

CreateThread(function()
  if GetResourceState('qbx_core') == 'started' then fw = 'qbx'
  elseif GetResourceState('qb-core') == 'started' then fw = 'qb'
  elseif GetResourceState('es_extended') == 'started' then fw = 'esx' end
end)

function M.framework() return fw end

function M.player(src)
  if fw == 'qbx' then return exports.qbx_core:GetPlayer(src)
  elseif fw == 'qb' then return exports['qb-core']:GetCoreObject().Functions.GetPlayer(src)
  elseif fw == 'esx' then return exports['es_extended']:getSharedObject().GetPlayerFromId(src) end
end

function M.identifier(src)
  local p = M.player(src); if not p then return nil end
  if fw == 'qb' or fw == 'qbx' then
    return p.PlayerData and p.PlayerData.citizenid
  elseif fw == 'esx' then
    return p.identifier
  end
end

function M.hasGroup(src, group)
  if fw == 'qbx' and exports.qbx_core and exports.qbx_core.HasGroup then
    return exports.qbx_core:HasGroup(src, group)
  end
  return false
end

function M.notify(src, msg, ntype)
  if fw == 'qb' then
    TriggerClientEvent('QBCore:Notify', src, msg, ntype or 'primary')
  elseif fw == 'esx' then
    TriggerClientEvent('esx:showNotification', src, msg)
  elseif fw == 'qbx' then
    if exports.qbx_core and exports.qbx_core.Notify then
      exports.qbx_core:Notify(src, msg, ntype or 'info')
    else
      lib.notify(src, { description = msg })
    end
  end
end

return M

        ## 13) Final Checklists (Copy & Ship)
        
        ### A) Discovery & Preflight

• Snapshot DB/files; create a staging server
• Pin artifacts and resource versions; define start order
• Inventory/target/menu dependencies listed
• Decide identifier strategy (citizenid crosswalk)

        ### B) Code Audit

• Grep for ESX/QB/QBOX/ox_*/mysql‑async
• List all money/inventory/job/duty calls
• List callbacks and server/client events

        ### C) Mapping & Design

• Choose adapter surface (player, ids, money, items, notify, callbacks)
• Decide dirty‑money strategy (account vs item vs alt wallet)
• Favor ox_lib/ox_inventory/ox_target

        ### D) Data Migration

• Build citizenid crosswalk
• Convert accounts/money
• Normalize vehicle metadata and plates
• Switch to oxmysql await calls

        ### E) QA Testing

• Event security: types/bounds/ownership/cooldowns
• Callbacks: return values under load
• Inventory metadata preserved
• Jobs/duty/group logic matches design

        ### F) Release & Rollback

• Tag release; changelog
• Keep pre‑migration snapshot for 7–14 days
• Monitor errors/latency; index hot queries

        ## 14) FAQ (with JSON‑LD Schema)

Q: Can I port QBCore scripts to QBOX without a full

Q: Can I port QBCore scripts to QBOX without a full rewrite?
A: With adapters and ox_lib callbacks, most scripts need only call remapping.

Q: What do I do with black/dirty money?

        **A:** Standardize in your adapter: ESX → `black_money` account; QB → item or extra account; QBOX → item or alt wallet (e.g., crypto). Keep one strategy project‑wide.

Q: Why do callbacks hang after moving to QBOX?
A: ESX/QB callbacks won’t fire on QBOX. Use lib.callback.register/await.

Q: Best way to migrate mysql‑async?

        **A:** Replace with **oxmysql** await APIs; remove callback pyramids.

Q: How do I convert qb‑target to ox_target?

        ## 15) Visuals (Suggestions)

• Flowchart (Discover → Map → Adapt → Migrate DB → Test → Release)
• Adapters Diagram: Script → Bridge → Framework (ESX/QB/QBOX)
• Rosetta Table: included above (export as CSV for downloads)

[Discover] → [Map APIs] → [Write Adapter] → [Migrate DB] → [Harden] → [QA] → [Release]

        ## 16) Legal & Ethical

• Respect licenses (MIT/GPL/NC). Do not bypass escrow or obfuscation.
• Convert only scripts you own or have permission to adapt.

        ## 28) Next Steps

• Drop the bridge.lua into your resource and start converting your highest‑value scripts first.
• Standardize on ox_lib + ox_inventory + ox_target + oxmysql to stay framework‑agnostic.
• Use the checklists during review and release.
