Methods

catch

  • catch<TResult = never>(
        onrejected?: null | (reason: any) => TResult | PromiseLike<TResult>,
    ): Promise<T | TResult>

  • Attaches a callback for only the rejection of the Promise.

    Type Parameters

    • TResult = never

    Parameters

    • Optionalonrejected: null | (reason: any) => TResult | PromiseLike<TResult>

      The callback to execute when the Promise is rejected.

    Returns Promise<T | TResult>

    A Promise for the completion of the callback.

finally

  • finally(onfinally?: null | () => void): Promise<T>

  • Attaches a callback that is invoked when the Promise is settled (fulfilled or rejected). The resolved value cannot be modified from the callback.

    Parameters

    • Optionalonfinally: null | () => void

      The callback to execute when the Promise is settled (fulfilled or rejected).

    Returns Promise<T>

    A Promise for the completion of the callback.

then

  • then<TResult1 = T, TResult2 = never>(
        onfulfilled?: null | (value: T) => TResult1 | PromiseLike<TResult1>,
        onrejected?: null | (reason: any) => TResult2 | PromiseLike<TResult2>,
    ): Promise<TResult1 | TResult2>

  • Attaches callbacks for the resolution and/or rejection of the Promise.

    Type Parameters

    • TResult1 = T
    • TResult2 = never

    Parameters

    • Optionalonfulfilled: null | (value: T) => TResult1 | PromiseLike<TResult1>

      The callback to execute when the Promise is resolved.

    • Optionalonrejected: null | (reason: any) => TResult2 | PromiseLike<TResult2>

      The callback to execute when the Promise is rejected.

    Returns Promise<TResult1 | TResult2>

    A Promise for the completion of which ever callback is executed.
