Why bother with best practices?
Best practices are a set of guidelines or recommendations that are widely accepted as the most effective and efficient way of achieving a particular goal or objective. There are several reasons why it's important to use best practices:
Achieve better results: Best practices have been tested and proven to be effective in achieving a particular goal or objective. By following best practices, you are more likely to achieve the desired results.
Save time and resources: Best practices help to streamline processes, reduce errors, and minimize waste. By following best practices, you can save time and resources that would otherwise be wasted on inefficient or ineffective methods.
Enhance quality: Best practices are designed to ensure consistency and quality in processes and outcomes. By following best practices, you can improve the quality of your work and deliver better results to your customers or clients.
Ensure compliance: Best practices often incorporate legal and regulatory requirements. By following best practices, you can ensure that you are complying with relevant laws and regulations.
Continuously improve: Best practices are constantly evolving and improving. By keeping up-to-date with best practices, you can continuously improve your processes and outcomes.
Overall, using best practices can help you to achieve better results, save time and resources, enhance quality, ensure compliance, and continuously improve.

Tool: Use Swagger for API documentation
Document public APIs: When documenting a Node.js project, it's important to focus on the public APIs that will be used by other developers. These APIs should be well-documented, including information on their purpose, inputs, and outputs.
Use a consistent format: Use a consistent format for documenting your code. This can help ensure that your documentation is easy to read and understand.
Keep documentation up-to-date: Documentation should be updated whenever changes are made to the code. Keeping documentation up-to-date can help prevent confusion and errors when using the code.
Include examples: Including examples in your documentation can help developers understand how to use your code. Examples should cover common use cases and provide clear instructions on how to use the code.
Organize documentation: Organize your documentation in a logical and consistent manner. This can help make it easier for developers to find the information they need.
Consider using a documentation generator: There are several documentation generators available for Node.js, including JSDoc and DocPad. Using a documentation generator can help automate the process of creating and maintaining documentation.
