What is River?

River is a powerful and easy-to-use tool designed to manage work queues in Go applications. Imagine you have a task that takes a long time to complete, such as sending emails to thousands of users or processing large images. Instead of blocking your main application, you can send these tasks to a queue and let River run them in the background.

Why use River?

1. Simplicity: River allows you to create and manage work queues with just a few lines of code.
2. Reliability: Your jobs will always run, even if your application restarts.
3. Scalability: River can handle variable workloads and grow with your application.
4. Flexibility: You can customize River's behavior to suit your specific needs.

What can you do with River?

• Process asynchronous tasks
• Send emails
