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();

Methods

  • get<T, U>(key: T, defaultValue?: U): U
  • @inheritDoc

    Type parameters

    • T: keyof ConfigurationOptions
    • U: undefined | string | number | boolean | Dictionary | StorageClient | EventManager | (radix?: number) => string | (fractionDigits?: number) => string | (fractionDigits?: number) => string | (precision?: number) => string | () => number | ({ (locales?: string | string[], options?: NumberFormatOptions): string; (locales?: LocalesArgument, options?: NumberFormatOptions): string })

    Parameters

    • key: T
    • optionaldefaultValue: U

    Returns U

externalgetEventManager

  • getEventManager(): EventManager

  • Returns EventManager

set

  • @inheritDoc

    Parameters

    Returns void

externaluseEventManager

  • useEventManager(events: EventManager): void

  • Parameters

    • externalevents: EventManager

    Returns void

externaluseStorageClient

  • useStorageClient(client: StorageClient): void

  • Parameters

    • externalclient: StorageClient

    Returns void

staticexternalgetEventManager

  • getEventManager(): EventManager

  • Gets default EventManager instance.

    Returns EventManager

staticgetGlobalConfig

  • @inheritDoc

    Returns Configuration

staticexternalgetStorageClient

  • getStorageClient(): StorageClient

  • Gets default StorageClient instance.

    Returns StorageClient

staticresetGlobalState

  • resetGlobalState(): void

  • 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.

    Returns void

staticexternalset

  • set(key: keyof ConfigurationOptions, value?: any): void

  • Sets value for given option. Only affects the global Configuration instance, the value will not be propagated down to the env var. To reset a value, we can omit the value argument or pass undefined there.

    Parameters

    • externalkey: keyof ConfigurationOptions
    • externaloptionalvalue: any

    Returns void

staticexternaluseStorageClient

  • useStorageClient(client: StorageClient): void

  • Parameters

    • externalclient: StorageClient

    Returns void
