Work in progress. 

An attempt to write a [Language Server Protocol](https://en.wikipedia.org/wiki/Language_Server_Protocol) server using the [BaseX websocket](https://docs.basex.org/main/WebSockets) feature.
## Server
* `webapp/lsp` The LSP implementation in XQuery using WebSockets  for transport and the [JSON-RPC](https://www.jsonrpc.org/specification) 2.0 API for format.
## Sample clients
* `webapp/static/codemirror` A test html page using the [CodeMirror6 editor](https://codemirror.net/)  that connects to the BaseX LSP instance
* `webapp/static/ace` A test html page using the [Ace editor](https://ace.c9.io/)  that connects to the BaseX LSP instance

## Uses
* https://github.com/mkslanc/ace-linters https://mkslanc.github.io/ace-linters/

* I needed `set NODE_OPTIONS=--max_old_space_size=8192` for build to complete
* or `node --max-old-space-size=8192 node_modules/webpack-dev-serve
r/bin/webpack-dev-server.js`
