Tips for creating code that continues to run in the "background" endlessly

I am facing the challenge of working with an API that has a limited request capacity, and I want to avoid exceeding this limit by having users directly access the endpoint. My solution involves using JavaScript to automate periodic requests to the API, which will then update a MongoDB cluster with the retrieved data. This way, users can access data stored in their local session storage, which is regularly updated with the data from the MongoDB cluster, instead of making direct requests to the API.

However, I am unsure how to actually implement this solution. I need the code to run autonomously, independent of the client, and to continue operating even when the webpage is not actively being visited. I welcome any suggestions or ideas on how to achieve this.

Answer №1

In order to ensure the security of API secrets and minimize the number of requests, it is essential for this process to be handled on the server-side.

Assuming you are using JavaScript on the server, you may want to consider utilizing npm packages such as heartbeat events or cron. Your server can continuously poll the API for updates, and then your clients can either periodically check for new information from the server or establish websocket channels for real-time notifications.

Answer №2

Execute this code block every five seconds

setInterval(function(){ /*insert your custom logic here */ }, 5000);

Answer №3

To tackle this task effectively, one approach is to develop a standalone application that operates on a specific schedule. In my case, I achieve this by crafting a compact console application, which I subsequently configure to run automatically using a cron job.

Since the specifics of your backend setup are unknown, it's challenging to offer a precise code solution. Nonetheless, the key is to create an executable script. Within this script, you would make a request to the external API and then store the retrieved data in your own database. Following the creation of this script, you can establish a timer event or cron job (depending on your system) to execute it at defined intervals.
