# Client Common Usage Guide
|
|
|
|
The client `common` addon contains shared browser UI bridge declarations and
|
|
common client-side browser integration patterns.
|
|
|
|
## Purpose
|
|
|
|
Use `forge_client_common` when a browser-backed feature UI needs reusable
|
|
screen lifecycle behavior:
|
|
|
|
- active browser control tracking
|
|
- browser ready state
|
|
- pending event queues
|
|
- `ExecJS` payload delivery
|
|
- shared bridge object inheritance through `createHashMapObject`
|
|
|
|
Feature addons still own their app-specific events and server RPC mapping.
|
|
|
|
## Shared Bridge
|
|
|
|
Initialize the bridge declarations with:
|
|
|
|
```sqf
|
|
private _webUIDeclarations = call forge_client_common_fnc_initWebUIBridge;
|
|
private _bridgeDeclaration = _webUIDeclarations get "bridgeDeclaration";
|
|
```
|
|
|
|
Feature bridges can inherit from the shared declaration:
|
|
|
|
```sqf
|
|
GVAR(MyUIBridgeBaseClass) = compileFinal createHashMapFromArray [
|
|
["#base", _bridgeDeclaration],
|
|
["#type", "MyUIBridgeBaseClass"],
|
|
["handleReady", compileFinal {
|
|
params [["_control", controlNull, [controlNull]]];
|
|
|
|
_self call ["setActiveBrowserControl", [_control]];
|
|
_self call ["sendEvent", ["myAddon::hydrate", createHashMap, _control]];
|
|
}]
|
|
];
|
|
```
|
|
|
|
## Event Delivery
|
|
|
|
`sendEvent` builds this payload:
|
|
|
|
```json
|
|
{
|
|
"event": "myAddon::event",
|
|
"data": {}
|
|
}
|
|
```
|
|
|
|
If the browser control is missing or not ready, the payload is queued on the
|
|
screen object. When the screen marks ready, `flushPendingEvents` delivers the
|
|
queue.
|
|
|
|
## Screen Lifecycle
|
|
|
|
The shared screen object tracks:
|
|
|
|
| Field | Purpose |
|
|
| --- | --- |
|
|
| `control` | Active browser control. |
|
|
| `readyState` | Whether the browser app has sent its ready event. |
|
|
| `pendingEvents` | Outbound events waiting for a ready browser. |
|
|
|
|
Call `handleClose` or `dispose` when a display closes so stale controls and
|
|
queued events are cleared.
|
|
|
|
## Current Consumers
|
|
|
|
The common bridge pattern is used by the newer bank, CAD, garage, and
|
|
organization client bridges. Store currently keeps its own bridge object and
|
|
browser bridge function names.
|
|
|
|
## Usage Rules
|
|
|
|
- Keep bridge inheritance in feature addons thin and explicit.
|
|
- Keep shared code generic; do not add bank, CAD, org, or store-specific logic
|
|
to `common`.
|
|
- Prefer namespaced events such as `garage::sync`.
|
|
- Send hash maps or arrays that can be safely serialized with `toJSON`.
|
|
- Avoid direct extension calls from the client bridge; send CBA server events.
