QBCore Architecture - QBCore Guide for FiveM

Introduction

This tutorial turns QBCore Architecture into a clean, developer-friendly guide for QBCore/FiveM. You will follow a step-by-step flow, copy the relevant code patterns, and learn the “why” behind the setup.

Requirements

• QBCore installed and running on a dev server
• Basic Lua knowledge and comfort reading FiveM patterns
• A test workflow for iterating safely (dev server, not production)
• Optional: a code editor with Lua/FiveM helpers (VS Code recommended)

Step-by-Step Guide

Step 1: Learning Objectives

In this step, you will apply the learning objectives concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 2: QBCore Framework Overview

In this step, you will apply the qbcore framework overview concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 3: Core Philosophy

In this step, you will apply the core philosophy concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 4: Framework Structure

In this step, you will apply the framework structure concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 5: Core Components

In this step, you will apply the core components concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 6: 1. QB-Core (qb-core)

In this step, you will apply the 1. qb-core (qb-core) concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 7: 2. Player Data Structure

In this step, you will apply the 2. player data structure concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Step 8: 3. Event System

In this step, you will apply the 3. event system concept as a practical change: define the pieces, wire them together, then verify the behavior in your dev server.

Tips & Best Practices

• Keep authority on the server: validate inputs before money/database operations.
• Start with one resource/module at a time, then refactor after you verify it works.
• Use callbacks for request/response flows and events for push/UX updates.
• When you run loops, avoid freezes: always yield with Wait() (client/server) and cache hot values.
