If you looked at the Leaflet GitHub activity chart exactly one year ago, you'd assume the project's future is pretty grim. But look at that amazing burst of activity since! Miracles do happen in open source. Thank you to everyone who makes this happen. โค๏ธ

A moment exactly 14 years ago. Later that year, what you see on the screens got released as @LeafletJS. At the time, I never would have dreamed of how much this little piece of code would impact my career and the mapping software industry as a whole. Good times!

Did you know the creator of Leaflet is also the frontman of an exceptional band with beautiful music? This is the best thing you'll see and hear today. ๐ต rain.in.ua/go/dity

Friends, today my band @obiymydoschu has released a new song from the upcoming album with a video made by my twin daughters. It's a true labour of love โ can't put into words how proud it makes me. Please watch, listen, add to your playlists and share โค๏ธ youtu.be/148g23r8PjI

Here's my conversation with @mourner on the story behind @LeafletJS, arguably the simplest mapping library and used on maps all over the Internet today
We talk about what makes maps complicated, keeping code simple, open source & life in Ukraine

A telling e-mail I got in response to the pro-Ukraine message on the @LeafletJS website. A Russian guy tells me that Russia is kind and peace-loving country liberating Ukraine from nazis, and because I'm lying about it, he will track down and slit the throat of my twin daughters.

Absolutely chilling to see Leaflet being used for this purpose. Ukrainian volunteers risking their lives to save people trapped by Russia-made flood, while Russians leave them to die and shoot at rescuers. #RussiaIsATerroristState #RussiaBlewTheDam

People in flooded areas under Russian control publish desperate pleas for help on social media. Volunteers collect them on an interactive map that now has more than 650 color-coded requests. Blue pins show those who can afford to wait for help, red denotes the most urgent cases.

May has been rough for ๐บ๐ฆ. Most of the nightly air raids on this viz are actual bombings of Kyiv with suicide drones and cruise/ballistic missiles. The last 3 nights were especially loud โ enough for my daughters to wake up. Donate here to help ๐ savelife.in.ua/en/donate-en

Wanted to release Leaflet 1.8.0 in the nearest days after a year of work but will have to delay once again. Woke up from explosions today, will have to deal with the fucking Russian invasion first. We will win, Russia is fucked ๐บ๐ฆ๐

So grateful for all the kind and overwhelming support we got over the last year, and standing for what's right. Leaflet community is the best! โค๏ธ๐บ๐ฆ From our DMs today:
ALT Twitter DM screenshot saying "FYI: our website experienced a massive DDOS attack (according to our hoster with a traffic volume which costs 5 digits minimum) - our assumption is that this is because we use leaflet.js and we also openly supported your position against the Russian aggressions/war). Just wanted you to know this - we will not back down & thx to our hoster we are back up again..."
