Best practices adopted for Mule 4

• Avoid implementing business logic in the interface layer.

• Make use of reusable flows if and whenever needed.

• Having a strategy for organizing files, like creating packages representing the API involved.

• Make use of Traits, ResourceTypes, DataTypes, and Examples to create reusable components and keep them in separated files.

• Use RAML DataTypes validations when possible.

• Identify and implement a reusable logic for handling common errors.

• Usage of custom error types for improved flexibility on handling errors.

• Extract common business logic and organize it into custom DataWeave Modules.

• In DataWeave, extract complex logic inside a function with a descriptive name.

• Always use a built-in function from DataWeave to achieve your goals – make sure to read the DataWeave documentation.

• Document yourself, so you always choose the best components for the logic you want to implement.
