There are many best practices to keep in mind when maintaining a web site, so it's helpful to have tools that check for common mistakes.
I've previously written about two Node.js packages I created for this purpose,
grunt-check-pages, both of which can be easily integrated into an automated workflow.
I updated them recently and wish to highlight two aspects.
There's a movement underway to make the Internet safer, and one of the best ways is to use the secure HTTPS protocol when browsing the web.
Not all sites support HTTPS, but many do, and it's good to link to the secure version of a page when available.
The trick is knowing when that's possible - especially for links created long ago or before a site was updated to support HTTPS.
That's where the new
--preferSecure option comes in: it raises an error whenever a page links to potentially-secure content insecurely.
Scanning a site with the
--preferSecure option enabled is now an easy way to identify links that could be updated to provide a safer browsing experience.
Aside: The moarTLS Chrome extension does a similar thing in the browser; check it out!
check-pages is easy to integrate into an automated workflow, but sometimes it's nice to run one-off tests or experiment interactively with a site's configuration.
To that end, I created a simple command-line wrapper that exposes all the
check-pages functionality (including
--preferSecure) in a way that's easy to use on the platform/shell of your choice.
Simply install it via npm, point it at the page(s) of interest, and review the list of possible issues.
Here's the output of the
