Golang Recipes Pro

An everyday Golang reference, from strings and collections to goroutines and design patterns. Every example comes with an explanation, and most of them run.

• 21 sections: basic types, arrays and collections, structs and interfaces, functions and closures, goroutines and channels, error handling, regular expressions, files, serialization, databases, algorithms, design patterns.
• Run in the app: the example actually runs and the output appears under the code. Needs an internet connection; the daily limit is 30 runs.
• What changed in new versions: 7 sections from Go 1.13 to 1.23, with the old and the new code side by side.
• Keyword and function reference: over 240 articles, browsable as a list or searchable by word.
• SQL alongside: over 200 queries against a live practice database (JOIN, GROUP BY, subqueries, data types). Queries have their own daily limit.
• Edit examples and add your own; they stay in the app and are always at hand.
• Search looks inside the code itself, not just the titles: remember a fragment and you will find the example.
• Everything except running works offline: examples, search, favorites.
• Comfortable to read: light and dark themes, your own font and size, line numbers, and long lines wrap instead of spilling off the screen.

Examples are drawn from professional sources and verified by running them.
