Monaco Editor Playground Code

// Configures two JSON schemas, with references.

var jsonCode = ["{", '    "p1": "v3",', '    "p2": false', "}"].join("\n");
var modelUri = monaco.Uri.parse("a://b/foo.json"); // a made up unique URI for our model
var model = monaco.editor.createModel(jsonCode, "json", modelUri);

const triggerCharacters = ['.', '$', '', '1', ':'];
monaco.languages.registerCompletionItemProvider('json', {
	triggerCharacters,

	// @ts-ignore
	provideCompletionItems: (model, position) => {
		const wordInfo = model.getWordUntilPosition(position);
		const { word, startColumn, endColumn } = wordInfo;

		const suggestions = [
		{
			label: `${word}${word}`,
			kind: monaco.languages.CompletionItemKind.Variable,
			insertText: `${word}${word}`,
			insertTextRules: monaco.languages.CompletionItemInsertTextRule.InsertAsSnippet,
		},
		];

		return {
			suggestions,
		};
	},
});


monaco.editor.create(document.getElementById("container"), {
	model: model,
});
