Coding practices

There are many best practices that are followed by developers around the world. Some of these can be as simple as following a code convention, or applying a more advanced pattern, principle, or general guideline. When building a microservice, its public APIs need to be designed carefully. The internal structure of a microservice is an implementation detail that doesn't get exposed to others.

You cannot ignore the fact that you are publishing a service, which is the face of your API. REST APIs have certain best practices, which should be followed. It's beyond the scope of this book to cover each of these practices, but standardizing on the resources and the request and response formats will go a long way in making the code consistent and easy to work with. Consider the following practices, which are focused towards this type of architecture:

• Follow DDD
• Document it
• Build for failure
• Infrastructure as part of code
