@date-io/core

What is @date-io/core?

The @date-io/core package is a utility library that provides a consistent interface to manipulate JavaScript dates across different date management libraries. It acts as an abstraction layer that allows developers to switch between date libraries like Moment, Date-Fns, Luxon, and Dayjs without changing the underlying application logic. This package is particularly useful in building UI components that require date manipulation functionalities, ensuring compatibility and flexibility across different date libraries.

What are @date-io/core's main functionalities?

Date Manipulation

Provides a consistent set of interfaces for date manipulation, such as parsing, formatting, and comparison, across different date libraries. This allows developers to easily switch between libraries like Moment.js and Date-fns without changing the date manipulation logic in their applications.

"Not applicable as @date-io/core itself does not provide direct manipulation methods, but rather interfaces for other libraries."

Localization and Timezone Support

Through its abstraction, it supports localization and timezone adjustments provided by the underlying date libraries, enabling developers to build applications with internationalization support without directly dealing with the complexities of each date library's localization features.

"Not applicable as @date-io/core itself does not directly handle localization or timezone, but enables these features through the underlying date library."

Date Utility Functions

Offers interfaces for common date utility functions like getting the start of the week, checking if a date is before another, and more, which can be implemented by the underlying date libraries. This standardizes how these utilities are accessed, regardless of the chosen date library.

"Not applicable as @date-io/core provides interfaces for utility functions rather than direct implementations."

Other packages similar to @date-io/core

moment

Moment.js is a standalone date manipulation library that offers a wide range of functionalities including parsing, validation, manipulation, and formatting of dates. Unlike @date-io/core, Moment.js is not an abstraction over different date libraries but a complete solution in itself. However, it's larger in size and has been considered legacy with the recommendation for new projects to consider alternatives.

date-fns

Date-fns provides over 200 functions to manipulate dates in JavaScript, such as formatting, parsing, and calculations on dates. It's modular, allowing developers to include only the parts they need, which can result in smaller bundle sizes compared to Moment.js. Date-fns is used directly for manipulation rather than serving as an abstraction layer like @date-io/core.

dayjs

Dayjs is a lightweight date library that offers a similar API to Moment.js but with a much smaller footprint. It includes plugins for additional functionalities such as localized formatting and timezone support. While it provides direct date manipulation capabilities, it does not abstract over other date libraries like @date-io/core does.

luxon

Luxon is a powerful, modern library for working with dates and times. It offers comprehensive features for parsing, formatting, manipulating, and querying dates and times. Luxon is designed with immutability and internationalization in mind. Unlike @date-io/core, Luxon is a standalone library focused on providing a rich set of date-time utilities rather than serving as an interface to unify different date libraries.
