#70 Golang - 'Must' Pattern Explained: Idiomatic Error Handling Made Easy

In this episode, we’re diving into the "Must" pattern in Go—a powerful way to simplify error handling for operations that must succeed. Whether you’re working with templates, regex, databases, environment variables, or HTTP query parameters, the Must pattern can make your code cleaner and more focused. Here's what you'll learn: ✅ What the "Must" pattern is and why it's useful ✅ How Go’s standard library uses this pattern (e.g., template.Must and regexp.MustCompile) ✅ Real-world examples with third-party libraries like sqlx’s MustConnect ✅ Writing your own `Must` helper functions for: Configuration file loading Critical environment variables Required HTTP query parameters 💡 The Must pattern isn’t just about simplifying code—it’s about making your intent clear while ensuring critical operations succeed. ⚠️ Caution: While the Must pattern is great for setup code and non-recoverable errors, it should be used thoughtfully.
