Export graph type automatically with an autofixable ESLint rule

[guyca]

Obsidian exposes a convenience type for typing graphs - dependenciesOf.

We can create an ESLint plugin to ensure each graph has the type exported correctly.

• The rule should be auto-fixable so the type is generated automatically on save
• The rule must take subgraphs into account.

Graph	Type
@graph() export class AppGraph extends ObjectGraph {}	export type = dependenciesOf;
@graph({subgraphs: [Subgraph]}) export AppGraph extends ObjectGraph {}	export type = dependenciesOf<[AppGraph, Subgraph]>;
