Interface: SearchablePlugin

Defined in: src/types/interfaces/plugin.interface.ts:1342

Plugin that supports on-demand search of external sources.

Remarks​

Extends IChivePlugin with search capabilities. Plugins implementing this interface can query external APIs directly when users search, rather than requiring bulk pre-import.

This approach:

  • Reduces storage requirements (only import claimed papers)
  • Ensures fresh data (real-time from source)
  • Minimizes API load on external services

Example​

class ArxivPlugin implements SearchablePlugin {
  readonly supportsSearch = true;

  async search(query: ExternalSearchQuery): Promise<ExternalPreprint[]> {
    const url = buildArxivQuery(query);
    const response = await fetch(url);
    return parseAtomFeed(response);
  }
}

Since​

0.1.0

Extends​

Properties​

id​

readonly id: string

Defined in: src/types/interfaces/plugin.interface.ts:378

Unique plugin identifier.

Remarks​

Must match manifest.id.

Inherited from​

IChivePlugin.id

manifest​

readonly manifest: IPluginManifest

Defined in: src/types/interfaces/plugin.interface.ts:383

Plugin manifest.

Inherited from​

IChivePlugin.manifest

supportsSearch​

readonly supportsSearch: true

Defined in: src/types/interfaces/plugin.interface.ts:1350

Discriminator to identify searchable plugins.

Remarks​

Used in type guards to distinguish from non-searchable plugins. Always set to true for SearchablePlugin implementations.

Methods​

getState()​

getState(): PluginState

Defined in: src/types/interfaces/plugin.interface.ts:453

Gets current plugin state.

Returns​

PluginState

Current lifecycle state

Example​

getState(): PluginState {
  return this.state;
}

Inherited from​

IChivePlugin.getState

initialize()​

initialize(context): Promise<void>

Defined in: src/types/interfaces/plugin.interface.ts:413

Initializes the plugin.

Parameters​

context​

IPluginContext

Plugin context with injected dependencies

Returns​

Promise<void>

Promise resolving when initialization complete

Remarks​

Called once when plugin is loaded. Use this to:

  • Subscribe to event hooks
  • Initialize plugin state
  • Validate configuration

If initialization fails, throw an error to prevent plugin from loading.

Example​

async initialize(context: IPluginContext): Promise<void> {
  this.logger = context.logger;
  this.cache = context.cache;

  context.eventBus.on('preprint.indexed', this.handleIndexed.bind(this));

  this.logger.info('Plugin initialized');
}

Inherited from​

IChivePlugin.initialize

search(query): Promise<readonly ExternalPreprint[]>

Defined in: src/types/interfaces/plugin.interface.ts:1366

Searches the external source for preprints matching the query.

Parameters​

query​

ExternalSearchQuery

Search parameters

Returns​

Promise<readonly ExternalPreprint[]>

Matching preprints from the external source

Throws​

If the search request fails

Remarks​

Implementations must:

  • Respect rate limits of the external API
  • Handle network errors gracefully
  • Return empty array (not throw) for no results

shutdown()​

shutdown(): Promise<void>

Defined in: src/types/interfaces/plugin.interface.ts:437

Shuts down the plugin.

Returns​

Promise<void>

Promise resolving when shutdown complete

Remarks​

Called when Chive is shutting down or plugin is being unloaded. Use this to:

  • Unsubscribe from event hooks
  • Close connections
  • Save state

Example​

async shutdown(): Promise<void> {
  this.logger.info('Plugin shutting down');
  await this.saveState();
}

Inherited from​

IChivePlugin.shutdown
