Improving performance, security, accessibility, SEO and more

In this article I'll show how I've improved my site performance by more than 300%, using Next.js, Vercel, Checkly and Lighthouse. I was also able to improve accessibility, security and adopt common web best practices.
And for that I've used one secret of Agile.

Hi Sergio.

Posts here on should contain actual substantial content, not just be intended to promote another external work. From the Terms of Use:

Users must make a good-faith effort to share content that is...not designed primarily for the purposes of promotion or creating backlinks. Additionally, posts must contain substantial content — they may not merely reference an external link that contains the full post.

However, DEV Listings may be appropriate for this.
(See the rules there.)

Thank you.

Thank you for the feedback. I will act accordingly next time.

🌚 Browsing with dark mode makes you a better developer.

It's a scientific fact.
