Handling dates and times in Redux Toolkit can sometimes be a bit tricky, especially when you need to manage time zones, manipulate dates, or format them in a user-friendly way. In this blog post, we will discuss some common scenarios and provide guidance on how to handle dates and times effectively in Redux Toolkit.

Storing Dates in Redux Store

When storing dates in Redux store, it’s recommended to use the JavaScript Date object or a library like moment.js to ensure consistency and ease of manipulation. For example, consider the scenario where you have a post object with a createdAt field representing the creation timestamp:

const post = {
  id: 1,
  title: 'My First Blog Post',
  createdAt: new Date(),
};

By using the Date object, you can easily compare, format, and perform calculations on the date within your Redux reducers and selectors.

Manipulating Dates

Redux Toolkit provides convenient methods for updating dates in your Redux store. For instance, let’s say you want to update the createdAt field of a post object to the current date:

const updatedPost = {
  ...post,
  createdAt: new Date(),
};

You can then dispatch an action to update the post object in your Redux store:

dispatch(updatePost(updatedPost));

Using the Date object allows you to easily modify any part of the date or time, such as adding or subtracting days, hours, minutes, etc.

Formatting Dates for Display

When displaying dates in your application, it’s important to consider the user’s locale and preferences. Redux Toolkit provides a powerful library called react-intl which allows you to format dates and times according to localized rules and preferences.

First, install the react-intl package:

npm install react-intl

Next, you can use the FormattedDate component from react-intl to format your dates in a user-friendly way within your React components:

import { FormattedDate } from 'react-intl';

const MyComponent = ({ date }) => (
  <p>
    Created at: <FormattedDate value={date} />  
  </p>
);

This will automatically format the date according to the user’s locale and display it in a human-readable format.

Conclusion

Working with dates and times in Redux Toolkit doesn’t have to be complicated. By using the Date object or libraries like moment.js in your Redux store, manipulating dates becomes straightforward and efficient. Additionally, utilizing the react-intl library allows for easy localization and formatting of dates for display.
