react-intl VS moment

I am developing an application with react/redux, and I started using library react-intl for formatting messages and dates.

I have been struggling mocking React-Intl library with Jest because I'm having this error when I run tests:

export function categoryIdToCategoryName(categoryId) {let name;switch (categoryId) { case constants.RISK_CATEGORY_LOW: name = 'low'; break; case constants.RISK_CATEGORY_MEDIUM: name = 'medium'; break; case constants.RISK_CATEGORY_HIGH: name = 'high'; break; case constants.RISK_CATEGORY_CRITICAL: name = 'critical'; break; default: console.warn('see: /utils/risk.js', 'categoryIdToCategoryName:', categoryId); name = 'unknown'; } return name;} I would like to translate this texts - [low, medium, high, critical] using https://github.com/yahoo/react-intl. So I defined messages

I'm using React-Intl with webpack and I need the Intl shim to support Safari and IE, but I don't want to load it for browsers that already support the Intl spec.

Ah, Moment.js, the guardian angel of date and time manipulation. Ever needed to format a date, calculate durations, or display something like "2 days ago"? Moment.js has got your back. It's a lifesaver for anything date and time-related, making it a must-have in your project, especially if you're into making your users feel like you really get them.

After hours of trying to figure out why Jekyll was still showing "Today" for a post I modified last week, I remembered that I am using the timeago filter from jekyll-timeago plugin. I was rendering the dates using {{ doc.last_modified_at | timeago }}. As you know, Jekyll is a static site generator, and it renders this as HTML at the time of build, and only then. This means any date rendered with timeago is hardcoded as is in the HTML and won't change until the next build. I switched all the dates to the "%-d %b %y" format for now. Might use moment.js in the future to get the timeago dates back.

For the longest time working with dates in JavaScript was a huge pain. That’s why libraries such as moment.js or date-fns are so popular. A lot of times I’d reach for these libraries when working with relative time formatting, but since late last year we’ve had pretty great browser support for the RelativeTimeFormat() method. In my mind, relative dates are just more visually appealing, especially for working with dates internationally. Dates like "5 days ago" or "in 2 months" are far more intuitive for users than 12/12/2023, or 03/11/2027. Folks in the US will see that as March 11, 2027, whereas the rest of the world will see that as November 03, 2027. What a nightmare.

We could control the DST flip by setting the test's input time to the appropriate time of year (summer/winter). However we couldn't control the timezone. We had to adjust the expected data in the test 🤢 using the same library which the production code used (momentjs).

This may sound a bit general but we can't forget about well-tought code. If we are using a lot of external dependencies, we can check if there aren't many lighter alternatives. Example? Some people are still using moment.js for date formatting. Why not use a lightweight 2kb alternative instead? Writing clean, organized and maintainable code won't give us a huge score boost but we are trying to save every byte of data, right? 😉
