How to access user settings for a snippets extension in VSCode - visual-studio-code

Question

I am trying to give the option to customise a VS Code Extension with user defined settings (configuration) of their preferred quote style. I have configured it in my package.json:
"contributes": {
"configuration": {
"type": "object",
"title": "Jasmine code snippets configuration",
"properties": {
"jasmineSnippets.quoteStyle": {
"type": "string",
"enum": [
"'",
"\"",
"`"
],
"default": "'",
"description": "Code snippets quote style"
}
}
}
},
And can access it in my settings.json like this:
"jasmineSnippets.quoteStyle": "`"
How can I now use that value in my snippets.json file? For this snippet, for example, I want to change the hardcoded ` to the configured property.
"it": {
"prefix": "it",
"body": "it(`${1:should behave...}`, () => {\n\t$2\n});",
"description": "creates a test method",
"scope": "source.js"
},
All I could find from the docs is not helpful as it assumes you're reading it from a JavaScript file not a JSON file:
You can read these values from your extension using vscode.workspace.getConfiguration('myExtension').

I think this requires implementing a CompletionItemProvider and returning the snippet from that, rather than statically declaring it in a JSON. Here's an example of what that might look like:
'use strict';
import * as vscode from 'vscode';
export function activate(context: vscode.ExtensionContext) {
vscode.languages.registerCompletionItemProvider('javascript', {
provideCompletionItems(doc, pos, token, context) {
var quote = vscode.workspace.getConfiguration('jasmineSnippets').get("quoteStyle", "`");
return [
{
label: "it",
insertText: new vscode.SnippetString(
`it(${quote}\${1:should behave...}${quote}, () => {\n\t$2\n});`),
detail: "creates a test method",
kind: vscode.CompletionItemKind.Snippet,
},
];
}
});
}
And then with "jasmineSnippets.quoteStyle": "\"" in the settings:
