This ESLint plugin aids in avoiding potential timezone-related issues in JavaScript applications when using date-fns library. Some functions such as endOfDay or endOfMonth from date-fns operate on the local timezone. If your application server resides in a different timezone than your users, it could potentially lead to bugs.
This plugin provides ESLint rules to highlight the usage of such functions and encourages developers to consider the implications of timezones in their applications.
Install this plugin via npm:
npm i @bsand/eslint-plugin-time-functions@latest --save-devAfter installation, you can configure this plugin in your ESLint configuration file (.eslintrc).
no-restricted-time-functions: This rule prevents the use of certain JavaScript time functions that could lead to timezone-related bugs.
For handling timezone-sensitive functions, consider utilizing timezone-aware methods or libraries. For example, here's a solution provided on Stack Overflow for using date-fns with timezones.
