Sets up a websocket proxy to a JSON-RPC server
|
||||
Sets up a websocket proxy for any number of language servers.
|
||||
|
||||
Each server is run as a subprocess which is connected to by sending the client
|
||||
to the URL /<language> based on a configuration file defined locally. For example,
|
||||
with the following defined as `servers.yml`:
|
||||
|
||||
```
|
||||
langservers:
|
||||
python:
|
||||
- python
|
||||
- python-langserver.py
|
||||
- --stdio
|
||||
go:
|
||||
- /usr/local/bin/go
|
||||
- langserver.go
|
||||
```
|
||||
|
||||
The client would connect to `ws://localhost/python` to get a python language server
|
||||
|
||||
Usage:
|
||||
|
||||
```
|
||||
npm install
|
||||
npm run prepare
|
||||
node dist/server.js --port 3000 --remotePath localhost --remotePort 2089
|
||||
node dist/server.js --port 3000 --languageServers servers.yml
|
||||
```
|
||||
|
||||
The only required flag to the server is `--remotePort`
