.cursorrules ES Module Node.js Guidelines

by @Danny Ayers

## General

- Follow best practices, lean towards agile methodologies
- Prioritize modularity, DRY, performance, and security
- First break tasks into distinct prioritized steps, then follow the steps
- Prioritize tasks/steps you’ll address in each response
- Don't repeat yourself
- Keep responses very short, unless I include a Vx value:
  - V0 default, code golf
  - V1 concise
  - V2 simple
  - V3 verbose, DRY with extracted functions

## Code

- Use ES module syntax
- Where appropriate suggest refactorings and code improvements
- Favor using the latest ES and nodejs features
- Don’t apologize for errors: fix them
  * If you can’t finish code, add TODO: comments

## Comments

- Comments should be created where the operation isn't clear from the code, or where uncommon libraries are used
- Code must start with path/filename as a one-line comment
- Comments should describe purpose, not effect

Overview of .cursorrules prompt

The .cursorrules file outlines guidelines for software development practices, emphasizing modularity, performance, and security, while adhering to agile methodologies. It encourages breaking down tasks into prioritized steps and specifies response priorities based on verbosity levels (V0 to V3). For coding, it advises using ES module syntax, suggesting refactorings with the latest ES and Node.js features, and including TODO comments when necessary. Comments should clarify operations not obvious from the code and describe the purpose rather than the effect. The file emphasizes correcting errors without apologies.
