Maintaining consistent code quality across React projects becomes critical in team environments where multiple developers contribute to the same codebase. With over 12 years of React experience since 2014 and as the creator of CoreUI, I’ve configured ESLint for countless production applications. ESLint is the industry standard JavaScript linter that catches errors, enforces coding standards, and integrates seamlessly with React projects. The configuration involves installing packages and creating a config file that defines your project’s linting rules.
