Discovering Google Lighthouse . A Small Tool That Changed How I See Web Development
Source: Dev.to
Introduction
Today I discovered something I honestly should have explored a long time ago: Google Lighthouse.
Why Lighthouse Matters
- It highlights performance, accessibility, maintainability, and user experience issues that are just as important as writing code.
- Tools like Lighthouse make the learning process feel less overwhelming by pointing you in the right direction.
Note: Don’t fall into the trap of chasing a perfect Lighthouse score instead of building useful projects. Many developers start optimizing numbers before validating whether the product itself solves a real problem. Lighthouse is a guide, not the final goal.
How to Run Lighthouse
You can run Lighthouse in several ways:
- Directly inside Chrome DevTools
- Through the command line
- As a Node.js module
My Experience with Lighthouse
For my portfolio specifically, Lighthouse exposed a few weaknesses immediately:
Large Unoptimized Images
- Images were not compressed or served in modern formats.
Accessibility Issues
- Missing alt text and insufficient color contrast.
Slow‑Loading Assets
- Scripts and stylesheets were not properly deferred or minified.
Missing Metadata
- Important meta tags (e.g., viewport, description) were absent.
These are things I probably would have ignored before, but discovering them made development more exciting. Every new tool feels like sharpening my sword a little better.
Conclusion
Until next time, fellow coffee addicts—maybe next time I’ll uncover another trick to become a better developer.
