ESLint

Find and fix problems in your JavaScript code

Get Started ยป

Find Problems

ESLint statically analyzes your code to quickly find problems. ESLint is built into most text editors and you can run ESLint as part of your continuous integration pipeline.

Fix Automatically

Many problems ESLint finds can be automatically fixed. ESLint fixes are syntax-aware so you won't experience errors introduced by traditional find-and-replace algorithms.

Customize

Preprocess code, use custom parsers, and write your own rules that work alongside ESLint's built-in rules. You can customize ESLint to work exactly the way you need it for your project.
