# Dependencies [#dependencies]

Orbit Lib always requires its two manifest libraries. Framework, inventory, target, and interface dependencies then depend on the exact selectors in `config.lua`.

## Required [#required]

| Dependency | Why it is needed                                                                                      | Link                                                            |
| ---------- | ----------------------------------------------------------------------------------------------------- | --------------------------------------------------------------- |
| `ox_lib`   | Loads the shared library, callbacks, cache helpers, and common runtime utilities used by the bridges. | [overextended/ox\_lib](https://github.com/overextended/ox_lib)  |
| `oxmysql`  | Satisfies the manifest dependency and database library loaded by the server runtime.                  | [overextended/oxmysql](https://github.com/overextended/oxmysql) |

## Selected integrations [#selected-integrations]

| Selector                                      | Required running resource                                     |
| --------------------------------------------- | ------------------------------------------------------------- |
| `Config.Framework = 'esx'`                    | `es_extended`                                                 |
| `Config.Framework = 'qb'`                     | `qb-core`                                                     |
| `Config.Framework = 'qbx'`                    | `qbx_core`                                                    |
| `Config.Framework = 'standalone'`             | No framework resource; configure standalone adapters instead. |
| `Config.TargetResource = 'ox_target'`         | `ox_target`                                                   |
| `Config.TargetResource = 'qb-target'`         | `qb-target`                                                   |
| Built-in `Config.Inventory` value             | The matching inventory resource.                              |
| `Config.Inventory = 'qb-like'` or `'ox-like'` | The resource named by `Config.CustomInventory`.               |

See [Configuration](/docs/orbit-studios-resources/orbit-lib/configuration) for the complete supported inventory list and custom export rules.

## Interface providers [#interface-providers]

| Provider                  | Additional requirement                                                                                             |
| ------------------------- | ------------------------------------------------------------------------------------------------------------------ |
| `framework` notifications | ESX or QB-Core. QBX and standalone fall back to ox\_lib.                                                           |
| `framework` progress      | QB-Core also requires `progressbar`; ESX also requires `esx_progressbar`. QBX and standalone fall back to ox\_lib. |
| `ox_lib`                  | Already installed as a required dependency.                                                                        |
| `orbit-dynamichud-v2`     | [Orbit Dynamic HUD 2.0](/docs/orbit-studios-resources/orbit-dynamichud), started after Orbit Lib.                  |

Text UI and skill checks support only `ox_lib` or `orbit-dynamichud`; they do not accept `framework`.

## Start order [#start-order]

```properties title="server.cfg"
ensure ox_lib
ensure oxmysql
ensure [framework-resources]
ensure [inventory]
ensure [target]
ensure orbit-lib

# Start this afterward when selected as an interface provider.
ensure orbit-dynamichud-v2

# Start every other dependent Orbit resource last.
ensure orbit-craftingsystem
```

## Feature failure behavior [#feature-failure-behavior]

* A missing or mismatched framework can leave player, money, job, gang, and usable-item data unavailable.
* A missing inventory or target prevents the matching bridge from registering correctly.
* A missing notification provider logs an error and shows no notification.
* A missing progress provider logs an error and uses the cancellation callback when supplied.
* A missing Text UI provider returns `false` from show, hide, and status operations.
* A missing skill-check provider returns `false` and can run the cancellation callback.
