Here is an example of using spellCheckDocument to spell check some text with a spelling issue.

`ts
import assert from 'node:assert';

import { spellCheckDocument } from 'cspell-lib';

// cspell:ignore wordz coztom clockz cuztom
const customWords = ['wordz', 'cuztom', 'clockz'];

async function checkSpelling(phrase: string) {
const result = await spellCheckDocument(
{ uri: 'text.txt', text: phrase, languageId: 'plaintext', locale: 'en' },
{ generateSuggestions: true, noConfigSearch: true },
{ words: customWords, suggestionsTimeout: 2000 }
);
return result.issues;
}

export async function run() {
console.log(Start: ${new Date().toISOString()});
const r = await checkSpelling('These are my coztom wordz.');
console.log(End: ${new Date().toISOString()});
// console.log(r);
assert(r.length === 1, 'Make sure we got 1 spelling issue back.');
assert(r[0].text === 'coztom');
assert(r[0].suggestions?.includes('cuztom'));
// console.log('%o', r);
}
`
