How to write to log from vscode extension?

Question

I am attempting to develop an extension with a language-server for VSCode. I am trying to figure out how to write text to log from language-server part of the extension. console.log produces nothing

Answer 1

Just as an update, you can use vscode.window.createOutputChannel to create the output container and then write to it with the appendLine method.

    //Create output channel     let orange = vscode.window.createOutputChannel("Orange");      //Write to output.     orange.appendLine("I am a banana."); 

Answer 2

You have to set an outputChannelName property on the client options inside the client extension code:

let clientOptions: LanguageClientOptions = {   outputChannelName: 'XYZ Language Server', }; 

Once you've done that you can use console.log() and it will be shown in the VSCode extension output panel.
