Converting a moment object to a string with a specific format using Moment.js

05 Oct 2023

Moment.js is a popular JavaScript library for parsing, manipulating, and formatting dates and times. One common task when working with Moment.js is converting a Moment object to a string representation with a specific format. In this blog post, we will explore how to achieve this using Moment.js.

Prerequisites

Before we dive into the conversion process, make sure to have Moment.js installed in your project. You can install it using npm or include it via a CDN in your HTML file.

// Using npm
npm install moment

// Using CDN
<script src="https://cdn.jsdelivr.net/moment.js/2.29.1/moment.min.js"></script>

Convert Moment Object to String

To convert a Moment object to a string with a specific format, we can use the format() method provided by Moment.js. This method allows you to define a pattern using various format tokens to represent different parts of the date and time.

Here’s an example that demonstrates how to convert a Moment object to a string in a specific format:

const now = moment(); // Create a Moment object representing the current date and time
const formattedDate = now.format("YYYY-MM-DD HH:mm:ss"); // Format the Moment object as a string

console.log(formattedDate); // Output: 2021-12-31 23:59:59

In the example above, we first create a Moment object using the moment() function without any arguments. This creates a new Moment object representing the current date and time.

Then, we use the format() method to convert the Moment object to a string with the desired format. In this case, the format pattern "YYYY-MM-DD HH:mm:ss" represents the year, month, day, hour, minute, and second parts of the date and time.

Finally, we log the formatted date string to the console.

Format Tokens

Moment.js offers a wide range of format tokens that you can use to customize the string representation of a Moment object. Here are some commonly used tokens:

YYYY: Four-digit year
MM: Two-digit month (01-12)
DD: Two-digit day of month (01-31)
HH: Two-digit hour of day (00-23)
mm: Two-digit minute (00-59)
ss: Two-digit second (00-59)

You can find the full list of format tokens in the Moment.js documentation.

Conclusion

Converting a Moment object to a string with a specific format is a common requirement when working with dates and times. With Moment.js, the format() method allows you to achieve this easily by specifying a format pattern using format tokens.

By following the examples and understanding the available format tokens, you can now convert Moment objects to strings with the desired format in your JavaScript projects.
