Keep-Awake

A lightweight, strictly-typed Node package to keep your free-tier servers (Render, Heroku, Railway, etc.) awake using a lightweight cron job.

Installation

npm i @ikeshav26/keep-awake

Basic Usage

Import the package and pass your server API URL and interval (in minutes). The package will ping the endpoint at that interval to prevent the server from falling asleep from inactivity.

import { keepAwake } from 'keep-awake';
import express from 'express';

const app = express();

app.get('/ping', (req, res) => {
    res.status(200).send('Server is awake');
});

app.listen(3000, () => {
    console.log("Server listening on port 3000");

    // Start pinging your server every 14 minutes
    keepAwake({
        url: "https://my-awesome-app.onrender.com/ping",
        interval: 14 // Interval in minutes
    });
});

Warning

Please use this package responsibly and ensure it complies with your hosting provider's Terms of Service for free-tier products.
