Monaco CSS Linter

Monaco CSS Linter is a simple CSS Linter plugin for the Monaco Editor. It uses the W3C CSS Validator under the hood to verify CSS Code.

Installation

npm i monaco-css-linter

Usage

import monaco, { editor } from 'monaco-editor';
import CSSMonacoLinter from 'monaco-css-linter';

// The Monaco Editor can be easily created, given an
// empty container and an options literal.
// Two members of the literal are "value" and "language".
// The editor takes the full size of its container.

const editor = monaco.editor.create(document.getElementById('container'), {
    value: 'css code here ...',
    language: 'css',
});

const linter = new CSSMonacoLinter(editor, monaco);
linter.watch();

You can get the linter response in this way :

import { CSSMonacoMarks } from 'monaco-css-linter';

//...

const cssCode = editor.getValue();
const report = new CSSMonacoMarks(cssCode);
const response = report.getLinterResponse();
