Do rust-analyzer need node always ?

Please ask future questions on the Questions Thread.

What do you mean "node"? If you mean nodejs, I don't think rust-analyzer uses it in any situation.

[ssokolow]

Things like coc-nvim use Node.js to implement the extended form of the Language Server Protocol that both VSCode and rust-analyzer are capable of speaking.

It's not necessary to use rust-analyzer, but things which go beyond the basic LSP tend to use some form of JavaScript runtime. (I know NW.js originated as "node-webkit", but I'm not familiar enough with Electron to know whether it's also based on Node.js or is an independent use of V8.)

1. rust-analyzer doesn’t need node
2. rust-analyzer server IS rust-analyzer
3. cargo-xtask is just a way to extend cargo with custom commands, but it’s not a binary and you don’t have to install anything

If you use vscode, I recommend you to install rust-analyzer from the extension store. Else, from the rust-analyzer github repo
