ESLint statically analyzes your code to quickly find problems. It is built into most text editors and you can run ESLint as part of your continuous integration pipeline.
The pluggable linting utility for JavaScript and JSX
ESLint is an open source project that helps you find and fix problems with your JavaScript code. It doesn't matter if you're writing JavaScript in the browser or on the server, with or without a framework, ESLint can help your code live its best life.
Find issues
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.
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.
Preprocess code, use custom parsers, and write your own rules that work alongside ESLint's built-in rules. Customize ESLint to work exactly the way you need it for your project.
We just pushed ESLint v10.0.0-beta.0, which is a major release upgrade of ESLint. This release adds some new features and fixes several bugs found in the previous release. This release also has some breaking changes, so please read the following closely.

ESLint has been critical in helping developers write high-quality JavaScript for years. We love that it catches common issues early and often. With a high level of extensibility, ESLint's ability to let teams enforce custom rules that work for them has been excellent for open-source projects and more. Chrome is happy to sponsor ESLint to help web developers write consistently high-quality code. It's an essential piece of the modern web development toolkit.
Nx uses ESLint to enforce code quality, library boundaries, and project visibility constraints. ESLint makes Nx more powerful, so on behalf of the Nx.dev community, we're proud to do our part and sponsor ESLint's continued success!
ESLint is an extremely useful tool for any JavaScript project. This tool allows us to set up consistent code formatting rules adopted by the whole team from the beginning of the project, greatly facilitates code reviews, and makes it easy to integrate new developers into the team. I know I am not alone in appreciating its flexibility and ease-of-use.
Most JavaScript projects directly or transitively depend on ESLint. An Indeed employee nominated ESLint to receive a donation from the FOSS Contributor Fund, and their colleagues clearly agreed. We're happy to support the open source technologies that allow us to develop, protect, and maintain the digital infrastructure that supports our products and helps people get jobs.
ESLint plays a major role in helping us create a safe and consistent experience across a growing number of codebases and engineers. We are grateful for all the open-source projects that are helping us build Contra, and ESLint is the first of many open-source projects that we are committed to back.
