* OpenStation App Framework — the WordPress host. |
| 4 |
* |
| 5 |
* Everything that couples the host-agnostic framework to WordPress |
| 6 |
* lives in this one file plus the adapters in `app/wordpress/`: |
| 7 |
* |
| 8 |
* - `init` @5 registers the shared client runtime script. |
| 9 |
* - `init` @10 loads every `.os.php` under the app directories |
| 10 |
* (`apps/` in this plugin, more via the |
| 11 |
* `openstation_apps_directories` filter) and fires |
| 12 |
* `openstation_apps_loaded` so plugins can add |
| 13 |
* `App` objects built in code. |
| 14 |
* - `init` @20 turns each allowed app into a native window (and |
| 15 |
* a desktop icon when it asked for one) through the |
| 16 |
* same `openstation_register_window()` / |
| 17 |
* `openstation_register_icon()` any plugin uses. |
| 18 |
* - REST `POST desktop-mode/v1/apps/<id>/dispatch` moves a |
| 19 |
* dispatch in and a response out of `App\Runtime`. |
| 20 |
* |
| 21 |
* Every app shares ONE script: `assets/js/app-runtime[.min].js`. It |
| 22 |
* mounts the window, sends actions, morphs the returned markup into |
| 23 |
* place and performs effects. An app ships no JavaScript of its own. |
| 24 |
* |

* (`rest_post_query`, the REST fields, the `_fields` projections the |

* boots it on demand, so call it from a `data()` or an action — a |
| 562 |
* `prefetch()`ed `data()` would boot it on every admin page load); |
| 563 |
* and because `_fields` runs before the embed, a projected collection |
| 564 |
* keeps its `_embedded` only when `_fields` names `_links,_embedded`. |
