New features

New features added should fall under the following categories:

  • It improves the interface between api and client in some way. An example may be to support websockets in @lbu/code-gen
  • It improves the developer experience one way or another while developing an api For example the lbu docker commands or various utilities provided by @lbu/stdlib

Although some parts heavily rely on conventions set by the packages, we currently aim not to be a framework. However, the idea of being a bit more of framework is not completely out of the door yet.
