JSHint, A Static Code Analysis Tool for JavaScript

JSHint is a community-driven tool to detect errors and potential problems in JavaScript code and to enforce your team's coding conventions.


  • This README is for people who are thinking about contributing to JSHint. For general usage please refer to our website.
  • If you want to report a bug about the website, please go to the jshint/site repository.
  • If you want to report a bug or contribute to our NPM package, please go to the jshint/node-jshint repository.

Reporting a bug

To report a bug simply create a new GitHub Issue and describe your problem or suggestion. We welcome all kind of feedback regarding JSHint including but not limited to:

  • When JSHint doesn't work as expected
  • When JSHint complains about valid JavaScript code that works in all browsers
  • When you simply want a new option or feature

Please, before reporting a bug look around to see if there are any open or closed tickets that cover your issue. And remember the wisdom: pull request > bug report > tweet.

Submitting patches

The best way to make sure your issue is addressed is to submit a patch. GitHub provides a very nice interface--pull requests--for that but we accept patches through all mediums: email, issue comment, tweet with a link to a snippet, etc.

Before submitting a patch make sure that you comply to our style. We don't have specific style guide so just look around the code you are changing.

Also, make sure that you write tests for new features and make sure that all tests pass before submitting a patch. Patches that break the build will be rejected.


To run tests you will need to install node.js and expresso. You can install the latter with npm:

npm install expresso

After that, running tests is as easy as:

expresso tests/*.js
