• Development Best Practices — Adopt coding standards, review rituals, and release checklists that keep resources stable.
• Performance Tuning — Benchmark your server, remove bottlenecks, and monitor changes over time .

Development Workflow

1. Environment Setup — Configure your IDE and tools (see VS Code Setup).
2. Resource Creation — Structure your scripts, exports, and configuration following the [Development Best Practices](/docs/d evelopment/best-practices).
3. Testing — Trace events and validate configs with the Debugging guide and the Config Validator.
4. Performance Review — Profile new features using the Performance Tuning guide and the Ev en t Debugger.
5. Deployment — Document release notes, update manifests, and coordinate rollouts with your team.

• Event Debugger — Inspect client/server event flow, payloads, and timings in real time.
• Built-in debugging functions such as QBCore.Functions.Print and logging helpers.
• Development commands and profiling utilities for capturing performance snapshots.
• Resource templates and starter projects to accelerate new system builds.
