ESLint is a tool for identifying and reporting on patterns found in ECMAScript/JavaScript code.
In many ways, it is similar to JSLint and JSHint with a few exceptions:
- ESLint uses Espree for JavaScript parsing.
- ESLint uses an AST to evaluate patterns in code.
- ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime.
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.
This is free and open source software.
Features include:
- Find issues – 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 problems 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.
- Configure – 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.
