This new property allows to know what's the relation with the schema
property and the different object types (map, datalayer, feature).
This serves two goals:
1. Check that the incoming messages make sense (it's possible to change
this property in this object)
2. Document where the property is used in practice. Because there is a
lot of properties, it's hard to keep track of where they are used.
This makes it explicit.
It's now it's responsability to get the authentication token from
the http server and pass it to the websocket server, it will make it
possible to redo the roundtrip when getting disconnected.
In some cases, you want to stop the propagation of events. The previous
code was using `fromSync=true` and `sync=false` interchangeably. This
makes it use `sync=false` everywhere.
Because we're relying on the `geoJSONToFeatures` method, we don't need
anymore updaters, the default ones (map, datalayer, feature) are enough.
It also makes the codebase compatible with our eslint configuration.
This can arise when the form isn't bound to a "syncable" object. We
might want to provide an utility to check an object is *syncable*, or a
specific form to not attempt to sync objects which don't need it.
Removing the `id` from the feature when cloning makes it generate a new
one. Without this change, the cloned feature keep the already existing
`id`, and during sync, the original object is lost (replaced by the
clone).
Nobody wants to be replaced by a clone.
The goal being for it to be hidden for now.
- Add a `is_owner` method on the map and use it in the view
- Remove duplicated line in `global.js`
- Rename `Datalayer` to `DataLayer` everywhere
- Move the sync flag in the map options (next to slideshow)
`WEBSOCKET_ENABLED`, `WEBSOCKET_HOST`, `WEBSOCKET_PORT` and
`WEBSOCKET_URI` have been added.
They are being transmitted to the client via the `map.options`.
When `WEBSOCKET_ENABLED` is set to `False`, the client doesn't have
the ability to be synced.
This changes how the syncEngine works. At the moment, it's always
instanciated, even if no syncing is configured. It just does nothing.
This is to avoid doing `if (engine) engine.update()` calls everywhere
we use it.
You now need to `start()` and `stop()` it.
This also changes the interface between the synced classes and the sync
engine.
The sync engines only requires two methods now:
- `getSyncMetadata()` which returns all the metadata needed, including
the `engine`.
- `render()` which renders the object, updating the needed parts.
Added a new `geometryToFeature` method in `umap.layer.js` which can
update a given geometry if needed.
A new `id` property can also be passed to the features on creation, to
make it possible to have the same features `id` on different peers.
Synced objects now expose different methods, such as:
- `getSyncEngine` which returns the location of the sync object.
- `getMetadata` which returns the associated metadata with the object.
Hooks have been added when features are created or changed, so the
changes can be synced with other peers.
