🔄 Async-Retrier 🔄
Async-Retrier is a simple yet powerful package to retry asynchronous functions until they succeed or reach the maximum number of retries.
💾 Installation
Install the package using NPM:
npm install async-retrier
Or using Yarn:
yarn add async-retrier
🚀 Usage
Import the asyncRetry
function from the package and use it with your desired asynchronous function:
import { asyncRetry } from "async-retrier"
const options = {
maxRetries: 5, // Number of retries, defaults to 3
delay: 5000, // Delay in milliseconds, defaults to 1000
timeout: 10000, // Timeout in milliseconds, defaults to 0. If set to a positive number, the operation will be cancelled if it takes longer than the timeout.
onRetry: (err, retries, delay) =>
console.log(
`Retry ${retries} failed with error: ${err}. Retrying in ${delay}ms.`
), // Function to call on error, default do nothing
}
const result = await asyncRetry(async () => {
// your asynchronous operation here
}, options).catch((err) => {
// handle error
})
console.log(result)

: An optional object with the following properties:maxRetries
