Node Lint & Formatting

This lesson is part of Node.js · All levels

Summary

Linting and formatting keep the quality and consistency of the code throughout the team. ESLint detects risky patterns such as unused variables, while Prettier standardizes writing styles such as indentations and comma marks. With both, the code review process is much more focused on logic, not style.

Key points

ESLint statically marks error and malicious code patterns
Prettier standardizes formats: spaces, quotes, and line lengths
Keep the pre-commit hook with the husky so the code is always clean.
The rules of the belt are kept light so as not to impede productivity
