Most FiveM resources look deceptively simple from the outside: drop a folder into your resources directory, add an ensure line, restart the server, and hope the console stays quiet. The small file doing much of the organizing behind the scenes is fxmanifest.lua.
This guide explains what a FiveM fxmanifest.lua does, how to read the most common entries, and how to spot configuration problems before they turn into a long night of restart-and-pray troubleshooting. It is useful for new server owners, developers reviewing a download, and anyone trying to understand why one resource starts cleanly while another refuses to cooperate.
What is fxmanifest.lua?
An fxmanifest.lua file is a resource manifest: a Lua-formatted metadata file that tells the FiveM runtime important facts about a resource. That can include which scripts should run on the client or server, which files must be available to players, which other resources are required, and whether the resource has a browser-based interface.
Think of it as a loading plan rather than the resource itself. Your actual logic may live in client Lua, server Lua, JavaScript, C#, configuration files, stream assets, or web files. The manifest tells FiveM how those pieces fit together.
Modern FiveM resources generally use fxmanifest.lua. You may still encounter older resources using an __resource.lua manifest, but that is legacy territory. For current syntax and supported directives, the best reference is the official Cfx.re resource manifest documentation.
The first lines: runtime version and game target
At the top of many manifests, you will see entries declaring an fx version and a game target. These identify the intended runtime context for the resource.
- fx_version identifies the FiveM runtime version level the manifest targets. Many contemporary resources use the cerulean version declaration.
- game identifies the game the resource is intended for, commonly GTA V in existing FiveM setups.
Do not treat these two lines as magic compatibility switches. Adding them will not make an old script compatible with a newer framework, and changing them will not repair missing exports, outdated natives, or bad configuration. They are foundational metadata, not a universal fix button.
Client, server, and shared scripts
The most important part of an fxmanifest.lua is often the list of scripts it loads. FiveM separates work between the player’s game client and the server, so where a script runs matters.
Client scripts
client_script or client_scripts entries load code on connected players’ clients. Client-side scripts are commonly used for markers, menus, camera work, local visuals, key inputs, vehicle behavior, and other interactions that must respond directly in the player’s game.
Client code should not be trusted with authoritative decisions. For example, a client can request an item reward or report that an action occurred, but the server should validate the request before changing money, inventory, permissions, or persistent player data. That is both a security rule and a sanity-preservation rule.
Server scripts
server_script or server_scripts entries run on the server. They are a better home for permission checks, database operations, economy logic, persistent data, and validation of client-triggered events.
A resource can contain only client code, only server code, or both. A resource with both sides usually communicates through FiveM events, callbacks supplied by a framework or library, exports, or another documented interface.
Shared scripts
shared_script or shared_scripts entries are for files needed in both environments. A shared configuration file is a familiar example: it can define locations, item names, prices, or feature toggles that both client and server code need to reference.
“Shared” does not mean “safe for secrets.” A file sent to clients should never contain database credentials, private API keys, privileged webhook URLs, or logic you expect players not to inspect. If a client needs the file, assume it can be read.
Script order is part of the resource design
When a manifest lists multiple scripts, the order can matter. A configuration file may need to load before the script that reads it. A utility module may need to load before another file calls one of its functions. This is especially relevant in large resources that split logic into many folders.
A sensible structure often looks like this:
- Shared configuration and constants load first.
- Shared utility files load next, if the resource uses them.
- Client or server feature files load after the data and helpers they depend on.
- Framework bridges or optional integrations load only when the creator documents that arrangement.
Do not randomly rearrange a paid or open-source resource’s manifest just because an error appears after startup. Read the error, check the author’s installation instructions, and identify the missing function or variable first. An order change can hide one symptom while creating three more.
Dependencies: what a resource needs before it can start
A manifest can declare dependencies. This signals that a resource relies on another resource or runtime component being available. Typical examples include a framework core, an inventory system, a target system, a library, or a database connector.
Dependencies are useful documentation, but they do not replace good installation notes. Server owners still need to install the correct dependency, configure it properly, and ensure it starts before the resource that uses it. A dependency declaration also cannot resolve a mismatch between framework versions or two resources that expect different APIs.
How to check dependency health
- Read the resource’s documentation and identify every required resource, not just the obvious framework name.
- Confirm the dependency folder name matches the name expected by the resource. Renaming folders casually can break references.
- Place ensure statements in a logical startup order in server.cfg.
- Look for the first relevant console error after startup, rather than chasing the last cascade of errors.
- Check whether the resource supports your specific framework version and any optional inventory, targeting, or notification integrations you use.

Files, data files, and streamed assets
Some resources need FiveM to know about files beyond their executable scripts. The files section can declare assets that must be included or made available, while data_file entries associate particular game data types with files used by the resource.
This becomes important for content such as vehicle metadata, handling data, weapon data, audio definitions, maps, and other game-facing assets. The exact data-file declarations vary by asset type, and copying a block from an unrelated vehicle or map package is a classic way to create loading trouble.
Streamed assets generally belong in the resource’s stream directory, but the correct folder layout and accompanying metadata depend on what you are adding. Follow the asset creator’s documentation and use a resource that is explicitly licensed for server use. A vehicle spawning successfully does not automatically mean its handling, sounds, tuning, LODs, or custom data were configured correctly.
NUI: when a resource includes a browser interface
Many modern FiveM resources use NUI, FiveM’s browser-based interface system, for inventories, phones, character selectors, menus, HUDs, and minigames. In a manifest, an ui_page points to the interface’s main HTML file, while the related HTML, JavaScript, CSS, fonts, images, and audio must be listed appropriately as resource files.
If a menu opens as a blank panel, a missing or incorrectly referenced web file is one possible cause. So is a JavaScript error inside the interface, a mismatched build folder, or a resource update that expects a different file layout. The manifest is worth checking, but it is only one layer of the diagnosis.
Common fxmanifest.lua mistakes
Using a file name that does not exist
A manifest can only load files that are actually present with matching capitalization and paths. This is easy to miss after moving a script into a subfolder or uploading a resource through a control panel.
Putting sensitive configuration in shared code
Anything loaded by clients should be treated as visible to clients. Keep secrets and privileged server-only settings in server-side files or a secure external configuration approach supported by your hosting setup.
Assuming one framework resource is interchangeable with another
A script written for one framework, inventory, targeting system, or library may need a documented bridge or rewrite for another. A clean-looking manifest does not guarantee ecosystem compatibility.
Editing a resource before saving a clean copy
Before changing a manifest, back up the original resource and record what you altered. This makes updates, troubleshooting, and support requests dramatically easier. “I changed a few things” is not a debugging log.
Ignoring the resource license
Manifests are easy to open, but that does not grant permission to redistribute, remove attribution from, unlock, or republish someone else’s work. Read the creator’s license and respect any rules around edits, support, and redistribution.
A quick review checklist before you ensure a new resource
- Open fxmanifest.lua and identify the listed client, server, and shared scripts.
- Check the resource documentation for required dependencies and supported frameworks.
- Confirm that all referenced files exist in the downloaded folder.
- Review configuration files before first launch, especially database, locale, job, item, and permission settings.
- Ensure dependencies start before the new resource.
- Start the resource in a test environment when possible and read the console from the first error onward.
- Test both the player-facing feature and the server-side outcome, such as item removal, payment, permissions, or saved data.
What this means for GTA VI creators
Learning to read a manifest is worthwhile because it teaches a broader habit: understand a mod or resource’s entry points, dependencies, assets, and client-server boundaries before installing it. Those habits transfer well across modding projects, even when tools and formats change.
That said, any comparison to future GTA VI modding is speculative and might not accurately represent current or future events. Rockstar has not announced a PC version of GTA VI or published a public GTA VI modding workflow, so existing FiveM resource conventions should not be presented as a confirmed blueprint for a future GTA VI ecosystem.
Read the manifest before blaming the resource
fxmanifest.lua is not exciting in the same way as a new MLO, a slick police tablet, or a custom car pack. But it is the map that tells FiveM what the resource is made of and how it should enter your server. Spending two minutes reading it can reveal missing dependencies, unsupported integrations, unsafe shared settings, and plain old missing files before players discover them for you.
