How to Edit Embedded Messages in Discord with Cron Jobs

If you’ve ever developed a Discord bot, you may have encountered the challenge of editing an embedded message after it's been sent. This issue often arises when working with scheduled tasks using cron jobs in a Node.js environment. In this guide, we'll guide you through the process of editing an embed that has already been dispatched to a channel by your Discord bot. Let's break it down step-by-step.

The Problem

You have a piece of code for a Discord bot that sends an embed to a channel. However, you want to edit this embed at a later time and are running into issues with asynchronous functions. You are receiving an error message indicating that an await cannot be used outside of an async function.

Here’s the relevant part of your code:

As seen, the await keyword is improperly placed, which results in an error when you attempt to run the bot.

The Solution

To effectively use the await keyword, you need to ensure that the containing function is declared as async. Here’s how to address the issue:

Step 1: Declare the ready Event as Async

Modify the client.once('ready') function to include the async keyword. This adjustment will allow the use of await within it. Here’s your updated segment of code:

Step 2: Setting Up the Cron Job

When using cron jobs, you can schedule tasks to run at specific intervals. In this case, you intend to edit the previously sent embed. Below is the code where we create a new cron job that fires on a specific schedule:

Conclusion

By organizing your code with the async keyword in the appropriate places and properly managing your embeds, you can efficiently update messages in Discord as per your requirements. This solution not only solves the immediate problem but also serves as a foundation for more complex bot functionalities in the future.

If you are building interactive bots with Discord.js and leveraging scheduled tasks, following this approach will help you manage your embeds seamlessly.

Happy coding!
