@types/d3-time
Advanced tools
Package description
The @types/d3-time package provides TypeScript type definitions for d3-time, a module in the D3.js library that allows for precise manipulation and formatting of dates for visualization purposes. It enables developers to work with time intervals, create time scales, and format dates in a way that's compatible with D3's visualization tools.
Creating Time Intervals
This feature allows you to create an array of dates representing each year (or other time interval) between a start and end date. It's useful for generating axes and labels in time-based charts.
import { timeYear } from 'd3-time';
const start = new Date(2020, 0, 1);
const end = new Date(2021, 0, 1);
const years = timeYear.range(start, end);Rounding and Snapping Dates
This feature enables rounding a date to the nearest time interval (e.g., month). It's useful for normalizing dates, such as snapping user-selected dates to the nearest month in a time series analysis.
import { timeMonth } from 'd3-time';
const date = new Date(2020, 6, 10);
const rounded = timeMonth.round(date);Filtering Dates
This feature allows filtering dates to only include those that match a specific time interval (e.g., every Monday). It's useful for creating custom time scales that, for example, only include business days.
import { timeMonday } from 'd3-time';
const start = new Date(2020, 0, 1);
const end = new Date(2020, 1, 1);
const mondays = timeMonday.every(1).range(start, end);Moment.js is a comprehensive date handling library for JavaScript. It offers a wide range of functionalities for parsing, validating, manipulating, and formatting dates. Compared to @types/d3-time, Moment.js provides more general-purpose date manipulation capabilities but lacks the specific focus on visualization and time intervals that d3-time offers.
date-fns is a modern JavaScript date utility library that provides the most comprehensive, yet simple and consistent toolset for manipulating JavaScript dates in a browser & Node.js. Unlike @types/d3-time, which is tailored for D3.js visualizations, date-fns offers a broader set of utilities for date manipulation without a specific focus on visualization.
Luxon is a powerful, modern, and friendly wrapper for JavaScript dates and times. It's designed to replace older libraries like Moment.js with a focus on internationalization and support for time zones. While Luxon offers robust time manipulation and formatting capabilities, it does not specifically cater to the needs of data visualization like @types/d3-time does.
