First there was LAMP, then there was MEAN and JAM. But now it’s 2022 and times have changed… What does the modern full stack look like? It’s built entirely from free and open source technologies, it’s scalable beyond imagination, it can run on premise or in the cloud, it should get out of the way and not lead to vendor lock-in, and most importantly it should “just work.” There are so many tools to choose from. Choosing the right stack from day one can be the difference from project success to smoldering pile of software ashes. Using fastify, mercurius, urql, and react we can build high performance full-stack applications using all javascript technologies.
