Hi, I’m just starting out with CodeMirror 6, trying to get a simple demo working of syntax highlighting of a JSON document.
This is what I have for my main code file (TypeScript), running in an otherwise empty HTML document:
import { basicSetup } from "codemirror";
import { EditorState } from "@codemirror/state";
import { EditorView } from "@codemirror/view";
import { json } from "@codemirror/lang-json";
function main(): void {
let startState = EditorState.create({
doc: JSON.stringify({array: [1, 2, 3, 4, 5], object: {bool: true, str: 'one two three four five'}, nothing: null}, null, 2),
extensions: [
basicSetup,
json(),
],
});
let view = new EditorView({
state: startState,
parent: document.body,
});
}
window.addEventListener('DOMContentLoaded', main, {once:true});
From what I have read, it seemed like this should be enough to get syntax highlighting via basicSetup, but currently the document remains unstyled. When the caret is over a curly brace or square bracket it does highlight the corresponding partner, though.
There’s no error recorded in the dev console. Any clues where am I going wrong?
Thanks!
