No broken links

No broken links (broken-links)

This hint checks and reports if any links in your page are broken. This includes anchor tag href value, image src value, script src value, video src value etc.

Why is this important?

Broken links gives your user a bad user experience.

What does the hint check?

This hint gets executed on all the below elements.

  1. img - checks src and srcset attribute values
  2. script- checks for src attribute value
  3. anchor - checks for href attribute value
  4. audio - checks for src attribute value
  5. video - checks for src and poster attribute values
  6. source - checks for src attribute value
  7. object - checks for data value attribute value
  8. link - checks for src attribute value
  9. track - checks for src attribute value

If the response status of the resource link is either 404 or 410 or 500 or 503, the URL will be flagged as a broken link.

Can the hint be configured?

You can change the HTTP method to make the requests (HEAD, GET, etc.). To do so, you need to configure the property method in your configuration .hintrc file:

    "connector": {...},
    "formatters": [...],
    "hints": {
        "no-broken-links": ["error", {
            "method": "GET|HEAD"

By default, this hint will use the HTTP GET method to request the URLs.

Examples that trigger the hint

Absolute URL

<a href="">Register</a>

<img src="" alt="logo">

Relative URL

<a href="/page-does-not-exist">Profile</a>

<img src="/image_does_not_exist.png" alt="logo">

Examples that pass the hint

URLs which return 200 OK will pass this hint.

URLs requested via <link rel="dns-prefetch"> or <link rel="preconnect"> resource hints will pass this hint if the request succeeds, regardless of status code.
