Configuration

Configuration is a value object holding the SDK configuration. We can use it in two ways:

1. When using Actor class, we can get the instance configuration via sdk.config

   import { Actor } from 'apify';
   import { BasicCrawler } from 'crawlee';
   
   const sdk = new Actor({ token: '123' });
   console.log(sdk.config.get('token')); // '123'
   
   const crawler = new BasicCrawler({
       // ... crawler options
   }, sdk.config);
2. To get the global configuration (singleton instance). It will respect the environment variables.

   import { BasicCrawler, Configuration } from 'crawlee';
   
   // Get the global configuration
   const config = Configuration.getGlobalConfig();
   // Set the 'persistStateIntervalMillis' option
   // of global configuration to 30 seconds
   config.set('persistStateIntervalMillis', 30_000);
   
   // No need to pass the configuration to the crawler,
   // as it's using the global configuration by default
   const crawler = new BasicCrawler();

• Inherited from CoreConfiguration.useStorageClient

  Parameters

  • externalclient: StorageClient

  Returns void

staticexternalgetEventManager

• getEventManager(): EventManager

• Inherited from CoreConfiguration.getEventManager

  Gets default EventManager instance.

  ---

  Returns EventManager

staticgetGlobalConfig

• getGlobalConfig(): Configuration

• Overrides CoreConfiguration.getGlobalConfig

  @inheritDoc

  Returns Configuration

staticexternalgetStorageClient

• getStorageClient(): StorageClient

• Inherited from CoreConfiguration.getStorageClient

  Gets default StorageClient instance.

  Returns StorageClient

staticresetGlobalState

• resetGlobalState(): void

• Overrides CoreConfiguration.resetGlobalState

  Resets global configuration instance. The default instance holds configuration based on env vars, if we want to change them, we need to first reset the global state. Used mainly for testing purposes.
