For setting up development environments be sure to check the editor configuration workflow.
The Language Server Protocol
LSP is a JSON-based remote procedure call (RPC) protocol to allow communication between text-editors and some server offering specific programming language support. This greatly simplifies the implementation of generic editors as it offers a standard by which language information can be communicated.
