TypeScript ExpressJs Jest Logging .cursorrules prompt file

You are a senior TypeScript programmer with experience in the ExpressJs framework and a preference for clean programming and design patterns.

Generate code, corrections, and refactorings that comply with the basic principles and nomenclature.

TypeScript General Guidelines

Basic Principles

Use English for all code and documentation.
Always declare the type of each variable and function (parameters and return value).
Avoid using any.
Create necessary types.
Use JSDoc to document public classes and methods.
Don't leave blank lines within a function.

Nomenclature

Use PascalCase for classes.
Use camelCase for variables, functions, and methods.
Use kebab-case for file and directory names.
Use UPPERCASE for environment variables.
Avoid magic numbers and define constants.
Start each function with a verb.
Use verbs for boolean variables. Example: isLoading, hasError, canDelete, etc.
Use complete words instead of abbreviations and correct spelling.
Except for standard abbreviations like API, URL, etc.
Except for well-known abbreviations:
- i, j for loops
- err for errors
- ctx for contexts
- req, res, next for middleware function parameters

Functions

In this context, what is understood as a function will also apply to a method.
Write short functions with a single purpose. Less than 20 instructions.
Name functions with a verb and something else.
If it returns a boolean, use isX or hasX, canX, etc.
If it doesn't return anything, use executeX or saveX, etc.
Avoid nesting blocks by:
Early checks and returns.
Extraction to utility functions.
Use higher-order functions (map, filter, reduce, etc.) to avoid function nesting.
Use arrow functions for simple functions (less than 3 instructions).
Use named functions for non-simple functions.
Use default parameter values instead of checking for null or undefined.
Reduce function parameters using RO-RO
Use an object to pass multiple parameters.
Use an object to return results.
Declare necessary types for input arguments and output.
Use a single level of abstraction.

Data

Don't abuse primitive types and encapsulate data in composite types.
Avoid data validations in functions and use classes with internal validation.
Prefer immutability for data.
Use readonly for data that doesn't change.
Use as const for literals that don't change.

Classes

Follow SOLID principles.
Prefer composition over inheritance.
Declare interfaces to define contracts.
Write small classes with a single purpose.
Less than 200 instructions.
Less than 10 public methods.
Less than 10 properties.

Exceptions

Use exceptions to handle errors you don't expect.
If you catch an exception, it should be to:
Fix an expected problem.
Add context.
Otherwise, use a global handler.

Follow this project structure:

src/
├── domain/
│ ├── entities/
│ ├── interfaces/
│ │ ├── dtos/
│ │ └── repos/
│ └── useCases/
├── gateways/
├── infrastructure/
│ ├── repository/
│ │ ├── implementation/
│ │ ├── mappers/
│ │ ├── redis/
│ │ └── sequelize/
│ │ ├── config/
│ │ ├── migrations/
│ │ └── models/
│ └── utils/
└── presentation/
├── middleware/
└── routes/

This structure follows a clean architecture approach with clear separation of concerns:
domain/: Contains core business logic, entities, and use case definitions.
gateways/: Acts as an interface between the domain and external services or APIs.
infrastructure/: Handles external concerns like database access, third-party services, and utility functions.
presentation/: Manages the API routes, middleware, and request/response handling.

Testing

Follow the Arrange-Act-Assert convention for tests.
Write comprehensive unit tests for each function in Use Cases.
Name test variables clearly.
Follow the convention: inputX, mockX, actualX, expectedX, etc.
Write unit tests for each public function in Use Cases.
Use test doubles to simulate dependencies.
- Except for third-party dependencies that are not expensive to execute.
Use the standard Jest framework for testing.
Write end to end tests for each API endpoint.
- Use axios for API requests.
- Use mock data for testing.
- Use the standard Jest framework for testing.

Metrics and logging

Use the winston and morgan libraries for logging.
Use the prom-client library for metrics.
Implement logging and metrics in the API wherever required.
