ViewRegistry
handles the association between model and view
types in Atom. We call this association a View Provider. As in, for a given
model, this class can provide a view via ::getView, as long as the
model/view association was registered via ::addViewProvider
If you’re adding your own kind of pane item, a good strategy for all but the simplest items is to separate the model and the view. The model handles application logic and is the primary point of API interaction. The view just handles presentation.
View providers inform the workspace how your model objects should be presented in the DOM. A view provider must always return a DOM node, which makes HTML 5 custom elements an ideal tool for implementing views in Atom.
You can access the ViewRegistry
object via atom.views
.
workspaceElement = atom.views.getView(atom.workspace)
textEditor = atom.workspace.getActiveTextEditor()
textEditorElement = atom.views.getView(textEditor)
pane = atom.workspace.getActivePane()
paneElement = atom.views.getView(pane)
Add a provider that will be used to construct views in the workspace’s view layer based on model objects in its model layer.

Returns a Disposable on which |
Get the view associated with an object in the workspace.
If you’re just using the workspace, you shouldn’t need to access the view layer, but view layer access may be necessary if you want to perform DOM manipulation that isn’t supported via the model API.
Argument | Description |
---|---|
|
The object for which you want to retrieve a view. This can be a pane item, a pane, or the workspace itself. |
