code-simplicity
Some practical refactoring examples how to reduce cyclomatic complexity
Instructions to the refactoring challenge
-
Clone the git repo to your local machine
git clone git@github.com:shaibo10/code-simplicity.git -
Install the dependencies for getting the complexity score by using ESlint
cd code-simplicity
npm i -
Run the script "challenge-score" to get the complexity score of the challenge
npm run challenge-score -
An important rule - you can't be sure that the server will return all the properties of the book, you need to validate that each property is exists
-
Start to refactor the challenge code and test the complexity each time
src/11/the-challenge.ts -
You can run the code using online IDE to test the functionality - https://stackblitz.com/edit/typescript
-
You can fake it (ESlint test the complexity in the function level), But try to improve the complexity of the all application
using advanced techniques you saw in the presentation and other examples from this repository -
