13 years ago today I made the first commit to the ESLint Git repo. It’s hard to believe that this project I cobbled together in my spare time over a couple of weeks is still going strong. I’ve been doing a lot of reflecting over these years and the journey it’s been. A thread.

btw turn this setting on 😙 and remember to turn it on on every device/browser you use bluesky on, because it's per client

I’ll be available for freelance work from August onwards. I can help you with: - Accessibility workshops, either in person or online - CSS workshops - Consultancy on HTML, CSS and accessibility - Front-end development EN or DE. Get in touch if that sounds interesting ❤️ matuzo.at/about-me

🧨 Axios only needed to be resolved somewhere in your dependency graph to affect you. Semver + transitive deps + runtime installs = hidden blast radius. If you only checked your project’s lockfile, you may still not know. socket.dev/blog/hidden-... #nodejs #javascript
