The Complete Microservice Tutorial: Introduction [Part 1] Project Link: https://github.com/Joker666/microservice-demo/ 159. How to Make Global Constant Maps and Slices in Go For the most part, Go developers are pretty good about using constants for global configuration, rather than global variables. A problem arises however when we want a global constant slice or map. The go compiler doesn't allow these more complex types to be set as constant. Many developers, upon making this realization, decide to then use a dangerous global variable. In this article we will explore a better option. 160. 5 Best Practices for Integrating with External APIs the must-have practices if you use external APIs 161.
