CodeMirror Spell Checker

Spell checking so simple, you can set up in 60 seconds. It will highlight any misspelled words in light red. Works great in conjunction with other CodeMirror modes, like GitHub Flavored Markdown.

Install

Quick start

Once CodeMirror is installed and loaded, first provide CodeMirror Spell Checker with the correct CodeMirror function. Then, just set the primary mode to "spell-checker" and the backdrop mode to your desired mode. Be sure to load/require overlay.min.js if you haven't already.

CodeMirrorSpellChecker({
	codeMirrorInstance: CodeMirror,
});

CodeMirror.fromTextArea(document.getElementById("textarea"), {
	mode: "spell-checker",
	backdrop: "gfm" // Your desired mode
});

That's it!

Customizing

You can customize the misspelled word appearance by updating the CSS. All misspelled words will have the .cm-spell-error class.

.CodeMirror .cm-spell-error{
	/* Your styling here */
}
