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.
intl-format-cache
Advanced tools
The intl-format-cache npm package is a utility for caching instances of Intl formatters, such as Intl.DateTimeFormat, Intl.NumberFormat, and Intl.RelativeTimeFormat. This can improve performance by reusing formatter instances instead of creating new ones each time formatting is needed.
Caching DateTimeFormat instances
This feature allows you to cache instances of Intl.DateTimeFormat. The code sample demonstrates how to create and reuse a DateTimeFormat instance for formatting dates in 'en-US' locale.
const { getDateTimeFormat } = require('intl-format-cache');
const dateTimeFormat = getDateTimeFormat('en-US', { year: 'numeric', month: 'long', day: 'numeric' });
console.log(dateTimeFormat.format(new Date()));
Caching NumberFormat instances
This feature allows you to cache instances of Intl.NumberFormat. The code sample demonstrates how to create and reuse a NumberFormat instance for formatting numbers as currency in 'en-US' locale.
const { getNumberFormat } = require('intl-format-cache');
const numberFormat = getNumberFormat('en-US', { style: 'currency', currency: 'USD' });
console.log(numberFormat.format(123456.789));
Caching RelativeTimeFormat instances
This feature allows you to cache instances of Intl.RelativeTimeFormat. The code sample demonstrates how to create and reuse a RelativeTimeFormat instance for formatting relative time in 'en-US' locale.
const { getRelativeTimeFormat } = require('intl-format-cache');
const relativeTimeFormat = getRelativeTimeFormat('en-US');
console.log(relativeTimeFormat.format(-1, 'day'));
The intl package provides a polyfill for the ECMAScript Internationalization API, which includes Intl.DateTimeFormat, Intl.NumberFormat, and Intl.RelativeTimeFormat. Unlike intl-format-cache, it focuses on providing the functionality where it is not natively available, rather than caching instances.
The formatjs package is a collection of libraries for internationalization in JavaScript, including react-intl and intl-messageformat. It provides more comprehensive solutions for formatting dates, numbers, and messages, but does not specifically focus on caching formatter instances like intl-format-cache.
The globalize package provides a comprehensive internationalization library based on the Unicode CLDR data. It supports formatting dates, numbers, and messages, and offers more extensive localization features compared to intl-format-cache, but does not specifically focus on caching formatter instances.
