🧩 Usage

Import craft

import { craft } from 'craft-lib';

Then access modules like:

craft.HttpClient.get('/api/data');
craft.DateUtils.formatDate(new Date());
craft.UUID.generate();
craft.Validator.validateSchema(...);

📚 Module Details

🔸 HttpClient (JWT + Fetch)

craft.HttpClient.get(url, token);
craft.HttpClient.post(url, body, token);

Token is optional. If provided, it sends as Bearer in Authorization header.

🔸 AxiosClient

craft.AxiosClient.get(url);
craft.AxiosClient.post(url, data);

Axios-based wrapper. You can configure interceptors.

🔸 DateUtils

craft.DateUtils.formatDate(date);           // "2025-04-29"
craft.DateUtils.formatTime(date);           // "13:05:08"
craft.DateUtils.addDays(date, 5);           // returns Date
craft.DateUtils.diffInDays(a, b);           // returns number

🔸 UUID

craft.UUID.generate(); // e.g. "9a6c7c0f-4cda-40f1-8a99-7e4b8ef582cd"

🔸 Validator

craft.Validator.validateModel(data, schema);
craft.Validator.isEmail(value);

Wraps common validation logic for frontend forms or backend schemas.

🔸 CR

Your own utility methods: debounce, cloneDeep, mergeObject, etc.

craft.CR.debounce(func, delay);
craft.CR.cloneDeep(obj);
