JAMStack has become increasingly popular and usage will explode during the upcoming years.
The JAMstack is not about specific technologies. It’s a new way of building websites and apps that deliver better performance, higher security, lower cost of scaling, and better developer experience. No rendering means greatly reduced attack surface area for malware, ultra-fast hosting on CDN, no debugging PHP or optimizing render times, and a super cheap way to scale your hosting.
The group is open to anyone interested. Whether you're new to the subject or you are an expert and want to share your knowledge.
