Logic Creation Overview

The most powerful aspect of Vibe Coding is that developers do not need to manually translate complex algorithms or business rules into code. By explaining the ‘purpose’ and ‘conditions’ of the logic you want to implement, the AI designs and implements optimized logic by referencing the project’s existing code style.

Step-by-Step Logic Implementation

The following is the process of adding a new feature that grants a ‘Popular’ tag based on the activity of a post.
  1. Defining Business Rules: Explain the conditions of the logic you want to implement.
    Prompt: “I want to add a ‘Popular Post’ feature to our board. Make the view count (viewCount) increase by 1 every time the post detail page is viewed, and implement logic so that when the view count exceeds 100, a ‘🔥Popular’ tag appears next to the post title.”
  2. Domain Model Expansion: The AI adds new fields to the Board entity and creates business methods in the service layer.
  3. Integration Implementation: The AI uses edit_existing_file to connect the controller and service logic, and writes code so that it can finally be reflected in the database.

💡 Tips for Efficient Logic Creation

  • Define Input/Output (I/O): Specifying input values and expected output values, such as “When A is entered, B should come out,” dramatically increases the accuracy of the logic.
  • Specify Exceptional Situations: Let the AI know in advance how to handle exception cases, such as “When there is no data, don’t throw an error, but return an empty object.”
  • Request Verification: Once logic creation is complete, increase the level of completion by requesting, “Review if there are any bugs in this logic and write test code.”
