node-package-tester

tool for testing npm packages.

🇺🇦 Help Ukraine

I woke up on my 26th birthday at 5 am from the blows of russian missiles. They attacked the city of Kyiv, where I live, as well as the cities in which my family and friends live. Now my country is a war zone.

We fight for democratic values, for freedom, for our future! I am stopping any support of my packages by the time until all russians leave my country on trucks or in boxes.

💛💙 Help Ukraine! We need your support! There are dozen ways to help us, just do it!
