What is minimal configuration of VPS for Vibed? It's look like that vibed's memory print is very small. But building of it can take much more RAM. So what is minimum?
I'm able to build and run the basic vibe-d application using 512MB of RAM. However, this dips down to about 256MB when using dub build --build-mode=singleFile. As @greenify said in his comment, the best option is to build on a development machine and copy the binary across to your server to be run. However, if you want to do all of the building on your VPS, then I would say 512MB of RAM as a good amount to have.
