Follow upstream links and confirm volatile functions, events, and configuration against the current repository.
Practical, source-linked guides for installing, understanding, and extending the open-source QBCore framework for FiveM.
Watch how easy it is to create powerful roleplay features with QBCore's intuitive API and modular architecture.
Network events cross a trust boundary. Validate the current player and every action input on the server.
Read current player state through the framework, then revalidate it before applying a sensitive change.
Use explicit exports between resources and verify their signatures at the commit your server deploys.
Send presentation-only notifications after the server has accepted or rejected a request.
Explore framework surfaces with examples that call out source, trust boundaries, and verification work.
Read current player state and revalidate it before server-side changes
local Player = QBCore.Functions.GetPlayer(src)
if not Player then return end
local job = Player.PlayerData.jobReview schema and queries at the same commit before applying database changes
local result = MySQL.scalar.await(
'SELECT 1'
)Network events cross a trust boundary and require server-side validation
RegisterNetEvent('example:server:status', function()
local src = source
if not QBCore.Functions.GetPlayer(src) then return end
end)Validate identity, permission, state, proximity, and values on the server
if type(amount) ~= 'number' then return end
if amount < 1 or amount > Config.MaxAmount then return end
if not hasPermission(src) then return endUse resmon and the profiler on a reproducible staging workload
-- Record the workload and baseline first
-- Change one variable, then measure againInspect each resource manifest and config at the deployed commit
-- Record the deployed commit
-- Review config and local diffs
-- Test changes on stagingQBCore resources load locale definitions declared in their manifests

Inspect qb-core and the maintained qb-* resources directly on GitHub.
Confirm current APIs and project-maintained guidance at docs.qbcore.org.
Review commits and pull requests before updating a customized server.
Check unresolved reports and document your own reproducible findings.
Start from a maintained deployment recipe, verify APIs at a pinned commit, and keep sensitive decisions on the server.
Deploy a test profile from the maintained txAdmin recipe
# Open txAdmin Recipe Deployer in a new test profile
https://github.com/qbcore-framework/txAdminRecipe
# Use an empty development database
# Keep the complete deployment log
# Run the first-boot smoke test before customizationRead one job from the current shared definitions
local policeJob = exports['qb-core']:GetShared('Jobs', 'police')
if not policeJob then
print('The police job is not defined at this commit')
return
end
print(policeJob.label)Treat every client event as an untrusted request
RegisterNetEvent('example:server:requestStatus', function()
local src = source
local Player = QBCore.Functions.GetPlayer(src)
if not Player then return end
TriggerClientEvent('QBCore:Notify', src,
'Server request accepted', 'success')
end)Follow source-linked references and compare volatile APIs with the deployed upstream commit before copying an example.
qbcore.net does not publish anonymous success stories as proof. Use these practices to evaluate every guide, including ours.
Follow upstream links and confirm volatile functions, events, and configuration against the current repository.
Record your current commit, review upstream diffs, and test customized resources on staging before production.
Include logs, resource versions, reproduction steps, and rollback results when sharing a fix with the community.
