Effortless JavaScript Retries with redo.js! 🚀

Tired of handling unreliable APIs, flaky database queries, or network failures? Instead of writing complex retry logic, let redo.js handle it for you—simple, powerful, and effortless!

Why redo.js?

✅ Works with Node.js, React, Vue, and more✅ Supports customizable retry strategies (exponential backoff, fixed delays, etc.)✅ Handles errors automatically with minimal code

📦 Installation

  • Using npm: 
npm install redo.js
  • Using yarn: 
yarn add redo.js

⚡ Usage

🔄 Retry Synchronous Operations

import { retryOperation } from "redo.js";

retryOperation({
  retryCount: 3, // Default: 3 - Number of retry attempts
  retryDelay: 1000, // Default: 1000ms - Delay between retries
  // incrementalDelayFactor: 2, // Optional - Exponential backoff factor

  retryCallback: () => {
    console.log("Retrying operation...");
    throw new Error("Operation failed");
  },
  onErrorCallback: () => console.log("An error occurred."),
  onSuccessCallback: () => console.log("Operation succeeded!"),
  afterLastAttemptErrorCallback: (error) =>
    console.error("Final error:", error.message),
});

🔄 Retry Asynchronous Operations

import axios from "axios";
import { retryAsyncOperation } from "redo.js";

const fetchData = async () => {
  return axios.get("https://jsonplaceholder.typicode.com/posts");
};

retryAsyncOperation({
  retryCount: 3,
  retryDelay: 1000,
  // incrementalDelayFactor: 2,

  retryAsyncCallback: async () => await fetchData(),
  onErrorCallback: (error, currentRetryCount) =>
    console.log(`Retry #${currentRetryCount} failed: ${error.message}`),
  onSuccessCallback: (response) =>
    console.log("Operation succeeded with status:", response.status),
  afterLastAttemptErrorCallback: (error) =>
    console.error("Final error:", error.message),
});

🚀 Try redo.js today and make your async workflows resilient!
