Build an internal error notification system in Go and Svelte

An internal error notification system is essential for large-scale systems to help developers quickly identify and fix issues by reporting logs through various channels such as email and Slack. This guide explains how to build such a system using the Go programming language and the Notify library, which can send notifications to multiple messaging services. It compares Notify with Sentry, highlighting that Notify is a package focused on sending notifications while Sentry is a comprehensive error tracking platform. The tutorial provides a step-by-step process, including setting up a project with Go's Echo framework, configuring Notify to send notifications, and creating a dashboard using Svelte and Tailwind CSS for the frontend. The system logs errors and sends them to the configured services, with a custom solution for Slack due to a bug in the existing package. A test environment is set up to ensure the integration works, and the project aims to enhance the stability and reliability of applications by allowing rapid identification and resolution of errors.
