JavaScript Retry Libraries

Retry libraries in JavaScript provide mechanisms to automatically retry failed asynchronous operations, such as API calls or database queries, to enhance reliability and resilience in applications. These libraries help manage transient errors by implementing various retry strategies, allowing developers to configure parameters like the number of retries, delay between attempts, and conditions for retrying. This is particularly useful in scenarios where network issues or temporary service outages may occur, ensuring that applications can gracefully handle failures without crashing or requiring manual intervention.

API

retry(retrier : Function, opts : Object) => Promise
  • The supplied function can be async or not. In other words, it can be a function that returns a Promise or a value.
  • The supplied function receives two parameters
    1. A Function you can invoke to abort the retrying (bail)
    2. A Number identifying the attempt. The absolute first attempt (before any retries) is 1.
  • The opts are passed to node-retry. Read its docs
    • retries: The maximum amount of times to retry the operation. Default is 10.
    • factor: The exponential factor to use. Default is 2.
    • minTimeout: The number of milliseconds before starting the first retry. Default is 1000.
    • maxTimeout: The maximum number of milliseconds between two retries. Default is Infinity.
    • randomize: Randomizes the timeouts by multiplying with a factor between 1 to 2. Default is true.
    • onRetry: an optional Function that is invoked after a new retry is performed. It's passed the Error that triggered it as a parameter.
