Check for broken links in yout website with jQuery
Version 0.2.0

Status.js will scan the website it's hosted on from the root (/) for links.
Internal links will be followed (fetched through Ajax) and scanned again. Yes, it's recursive.
External links will be memorized and used for cross-referencies. You can't check if an external link is broken with Status.js because of the cross-domain limitation of Ajax calls.
A table with some nice data will be populated in real time while Status.js is working.
Sometimes something more graphic is better, so I implemented the Javascript InfoVis Toolkit (Jit) in Status.js to plot the website as a graph you can interact with.
Last but not lest, there is a sitemap.xml generator that makes use of the crawler work. Nothing fancy, but if you can't generate a sitemap in a more correct way it can be useful.
## How is it done?
Status.js is a Backbone application.
For Ajax and DOM manipulation, there is jQuery.
The url manipulation is powered by jsUri.
Plotting done with Javascript InfoVis Toolkit (Jit).
The GUI part is Twitter Bootstrap.
The url of the page. To avoid duplication, hashes will be removed.
Available for internal pages only, the title tag is fetched. If not present, you'll get a {No title} placeholder.
Available for internal pages only, the meta name="description" tag is fetched. If not present, you'll get a {No description} placeholder.
Because of the Javascript-in-a-browser limitations, we can handle only these statuses:
- Success
- Available for internal pages only, means a correctly fetched page.
- External
- Indicates an external link.
- Redirect
- Indicates that there is another page for the same url but with a trailing slash. It's an hack around the browser that does not return any 30x http code
- Error
- _Broken link!_
- Unfetched
- Page memorized but waiting to be crawled.
### Out links
It's the number of internal and external links present in the page. Clicking on the number you'll get the full list.
It's the number of pages that link to the url. Clicking on the number you'll get the full list.
This is a list of some of the things I'll have to work on. Please feel free to contribute with suggestions!
- Warnings about duplicate/too long/missing titles/descriptions.
- Verify for the presence of Google Analytics.
- Check for broken images
- Warning about missing/bad alt tags for images.
- Pagination
- Performance tests
- Let's be honest... do tests!
- Code cleaning, comments, etc.
