Combatting Alert Fatigue by Prioritizing Malicious Intent
In 2023, data breaches surged 78% from zero-day and supply chain attacks, but developers are still buried under alerts that are unable to prevent these threats.
@formatjs/intl-relativetimeformat
Advanced tools
@formatjs/intl-relativetimeformat is a JavaScript library that provides a way to format relative time strings, such as '3 days ago' or 'in 2 weeks', using the ECMAScript Internationalization API (Intl.RelativeTimeFormat). It is part of the FormatJS suite of libraries designed to help with internationalization in JavaScript applications.
Basic Relative Time Formatting
This feature allows you to format relative time strings in a human-readable format. The example shows how to create an instance of IntlRelativeTimeFormat and use it to format relative times in English.
const { IntlRelativeTimeFormat } = require('@formatjs/intl-relativetimeformat');
const rtf = new IntlRelativeTimeFormat('en', { numeric: 'auto' });
console.log(rtf.format(-1, 'day')); // Output: 'yesterday'
console.log(rtf.format(2, 'week')); // Output: 'in 2 weeks'
Customizing Numeric Display
This feature allows you to customize how numeric values are displayed. By setting the 'numeric' option to 'always', you can ensure that the output always includes the numeric value, even for common time frames like 'yesterday' or 'tomorrow'.
const { IntlRelativeTimeFormat } = require('@formatjs/intl-relativetimeformat');
const rtf = new IntlRelativeTimeFormat('en', { numeric: 'always' });
console.log(rtf.format(-1, 'day')); // Output: '1 day ago'
console.log(rtf.format(2, 'week')); // Output: 'in 2 weeks'
Localization Support
This feature demonstrates the library's support for multiple languages. The example shows how to format relative time strings in French.
const { IntlRelativeTimeFormat } = require('@formatjs/intl-relativetimeformat');
const rtf = new IntlRelativeTimeFormat('fr', { numeric: 'auto' });
console.log(rtf.format(-1, 'day')); // Output: 'hier'
console.log(rtf.format(2, 'week')); // Output: 'dans 2 semaines'
date-fns is a modern JavaScript date utility library that provides a variety of functions for manipulating and formatting dates. It includes a function called formatDistance, which can be used to format relative time strings. Compared to @formatjs/intl-relativetimeformat, date-fns offers a broader range of date manipulation utilities but may require more configuration for internationalization.
Moment.js is a widely-used JavaScript library for parsing, validating, manipulating, and formatting dates. It includes a fromNow method that can be used to format relative time strings. While Moment.js is feature-rich and easy to use, it is larger in size compared to @formatjs/intl-relativetimeformat and has been deprecated in favor of more modern alternatives.
Luxon is a modern JavaScript library for working with dates and times, created by one of the Moment.js developers. It provides a method called toRelative, which can be used to format relative time strings. Luxon is a more modern and lightweight alternative to Moment.js, with better support for internationalization and time zones.
