Like most things in development, Create React App is practically magic right up until you’re ready to get into some nitty-gritty customizations. If you aren’t familiar with it and need a little help getting started, consult Getting Comfortable with Create React App. Let’s use Create React App to quickly set up a React project. The focus of this article will be on project-level linting with ESLint. While linting locally can and will save us time, there is always the bigger picture - like different code editors and dev environments. Most popular code editors either automatically include a linter for the language you’re using or offer multiple extensions so that you can configure how you prefer to lint locally. By implementing a linter in our code editor and our project, we can save time by discovering errors before we even execute our code. Understanding LintingĬoding always leaves room for errors, especially with loosely typed languages like JavaScript.

Projects created using Create React App have linting with ESLint already working and configured out of the box with sensible defaults. Linting is one approach to establishing consistency and clarity by enforcing coding rules and standards. Despite whether you like spaces or tabs, semicolons or none, single or double quotes, we can all agree on the importance of consistency and clarity in a codebase.
