Hi,

Let me preface this with a caveat that I'm not super fluent in all the terminology around language servers (i.e. I don't know what a "code lens" is), so please be gentle if I'm using the wrong terms for things.

I'm writing an application using vanilla js + WebGL and my development stack is:

• emacs
• lsp-mode
• company-mode
• ts-ls installed through emacs

Completion works fine for the core parts of javascript, e.g. getElementByID() and friends. But if I want to call into, let's say, the canvas API, I don't have completion working. Here's an example:

var canvas = document.getElementById("foo");
var ctx = canvas.getContext("bar");

Note how the getContext isn't offered by the language server as a completion option.

Here's a second example:

xmlr = new XMLHttpRequest();
xmlr.open('GET', url, false);

Similarly, the open isn't offered as a completion option.

How do I fix this?
