Instructions for usage from non-js editors

[aaronjensen]

Hi, I spent a little bit of time trying to figure out how to communicate w/ vscode-jsonrpc from emacs (or even from the command line) and I'm hitting a wall.

I would expect to be able to do something like:

$ node prettier-rpc.js
Content-Length: 62
{"jsonrpc":"2.0","id":0,"method":"format","params":"x=>{x()}"}

But that doesn't do anything. I'm sure there's something I don't know about pipes or writable stream .write. Any tips you could provide would be helpful, thanks!
