What is webhint?

webhint is a linting tool for the web, with a strong focus on the developer experience: easy to configure, develop, and well documented.

webhint doesn’t want to reinvent the wheel. For that reason it tries to integrate other tools and services that do a great job, and contribute back where appropriate. For example, we are using axe for accessibility, SSL Server Test for checking the certificate configuration, etc.

What is webhint’s goal?

We have a few:

  • Bring the community together to decide what best practices are in several areas.
  • Help web developers write the best possible code.
  • Clean up the web of bad practices.
  • Promote community tools and services that do an awesome job but could not be known by everybody.

Who started webhint?

webhint’s development started inside the Microsoft Edge team. Early on, the team realized that not only the project had to be open source, but also be community driven. The best way to achieve that was by donating the code to the JS Foundation, have a governance model that welcomes input for anyone in the web community (browser vendors, web experts, and developers), and continue the work there.

What can I do to help?

There are lots of things you can do to make webhint better, from reviewing documentation, writting new one, filling bugs, triaging, coding, etc.

We will gladly accept any contribution you can do. Most of the issues in webhint should have a difficulty level. Also don’t hesitate to ask for help.

What browsers are supported?

A developer tools extension is available for Chrome, Edge (Chromium), and Firefox. The webhint CLI can be run against jsdom or any browser supported by puppeteer. If your favorite browser is not supported you can always develop a connector for it!

Is there a plugin for my favorite editor?

A webhint extension for Visual Studio Code is currently available. It utilizes the Language Server Protocol which makes it suitable for porting to other editors if there’s community interest.

Is there an online service?

Yes! You can scan an online website in here.

If you have any feedback on the results page, please open an issue in the website repository. If the issue is related to the results themselves, then open an issue in the webhint repository.

Our logo is Nellie the narwhal. Narwhals are not only awesome but have one of the best sonars in the animal kingdom.

Narwhal echolocation beams may be the most directional of any species.

Recordings of narwhal (Monodon monoceros) echolocation signals were made using a linear 16 hydrophone array in the pack ice of Baffin Bay, West Greenland in 2013 at eleven sites. An average -3 dB beam width of 5.0° makes the narwhal click the most directional biosonar signal reported for any species to date.

I don’t agree with one of your hints, how can I tell you?

Great, let’s make it better! You can open an issue here telling us what you think can be improved.
