Performance, Progressive Web App, Best Practice, and Accessibility Audits built right in to Calibre
It’s been almost two months since the release of Test Profiles and Budgets 2.0, and the response has been mind-blowing. 👏
I’m excited to announce the next major feature release:
I’m glad you asked. Lighthouse is an Open Source project by the Google Chrome team that helps developers improve user experience through Progressive Web App, accessibility and best practice tests. 💅
In development since March 2016, Lighthouse has quickly grown into an absolutely indispensable suite. As of today, Lighthouse is available in three forms: a browser extension, an NPM package and also directly in Chrome Devtools.
Despite three methods of using Lighthouse, to do so continuously, we’d be left with a non-trivial task of writing custom scripts and deploying servers, rather than focusing on delivering better Web experiences to our customers.
It became clear that pairing Calibre with Lighthouse can offer an even more comprehensive landscape of performance, accessibility and offline capability.
Lighthouse provides audits for four areas of focus: Performance, Progressive Web Apps, Best Practices and Accessbility.
Calibre brings those Lighthouse audit scores to the forefront as a familiar A-F grading system.
These audits provide actionable advice that will make apps faster, better to use and more accessible to a larger audience.
Calibre runs Lighthouse as part of every snapshot, which is great because:
The introduction of Lighthouse also brings in a few new metrics:
These user focused metrics are crucial to improving user experience, and like any other metric in Calibre, budgets can be set against them. 📈💥
Calibre Lighthouse is available for all account tiers, as of right now… actually, that’s a lie—we’ve been running Lighthouse for a little over a week now, so drop everything and go check your account as it’s already filled with data 😎
The Lighthouse Team: Brendan, Patrick, Eric, Ward and Paul have been intensely focused on shipping Lighthouse 2.0 in time for Google i/o, and have not wavered in their aid to make Calibre Lighthouse a reality.
I can’t thank them enough. 💙
Lighthouse is now also built into Chrome Devtools, audit your site during development, and monitor real world environments using Calibre. It’s a match made in heaven 👼
