d3-time-format
Advanced tools
The d3-time-format package is a JavaScript library for parsing and formatting dates. It is part of the D3.js collection of tools for data visualization, but it can be used independently for dealing with date and time formatting. It provides a way to specify custom formats for dates and times, as well as parse strings into date objects based on these formats.
Formatting Dates
This feature allows you to format a JavaScript Date object into a string based on a specifier string. The specifier controls how various parts of the date are displayed.
"%Y-%m-%d".format(new Date())
Parsing Dates
This feature enables you to parse a string representing a date into a JavaScript Date object using a format specifier that matches the format of the string.
d3.timeParse("%Y-%m-%d")("2023-04-01")
Locale Support
This feature allows you to use locale-specific date and time formatting. You can define your own locale with custom time formatting symbols, or use predefined locales.
d3.timeFormatLocale(locale).format("%c")(new Date())
Moment.js is a legacy package for date and time manipulation and formatting. It offers a wide range of functionalities similar to d3-time-format but is no longer recommended for new projects due to its size and the availability of more modern alternatives.
date-fns provides a collection of simple, pure functions for manipulating JavaScript dates. It is modular and has a similar scope to d3-time-format, but it is designed to be more lightweight and with a functional programming approach.
Luxon is a powerful, modern library for working with dates and times. It offers a fluent API and comprehensive time zone support. Compared to d3-time-format, Luxon provides more extensive functionality around date arithmetic, parsing, and internationalization.
Day.js is a minimalist library that parses, validates, manipulates, and displays dates and times for modern browsers with a largely Moment.js-compatible API. It is lightweight and can be a good alternative to d3-time-format for simple date formatting and parsing tasks.
