com.fulcrologic.fulcro.algorithms.indexing — com.fulcrologic/fulcro 3.7.8

Functions that implement the query and component indexing. Fulcro keeps indexes of on-screen components by ident and class. These enable Fulcro to find on-screen components for things like targeted refresh. You are allowed to use the indexes to find components for whatever purpose suits your needs (e.g. looking at component options).

drop-component! clj/s

(drop-component! this)

(drop-component! this ident)

Remove the component instance from the indexes. If ident is supplied it uses that, otherwise it gets the ident from the component itself.

index-component! clj/s

(index-component! this)

Add a component instance to the app index. This adds the component to the class->components and ident->components indexes.

index-query clj/s

(index-query query)

Create an index of the given component-annotated query. Returns a map from query keyword to the component class(es) that query for that keyword.

index-root! clj/s

(index-root! app)

Index the root query (see index-query) and side-effect the result (prop->classes) into the given app. This function assumes the root-class has already been supplied to the app (i.e. is has been mounted).

link-query-props clj/s

(link-query-props {:keys [key children] :as ast})

Returns a set of all of the keys that appear in link refs [:k '_] in the entire ast.

reindex clj/s

Mutation: re-index the application (typically after a dynamic query change).

top-level-keys clj/s

(top-level-keys ast)

Return a set of keywords that are in the top-level of the given AST
