How to customize Rome date picker styles?

Rome allows full CSS customization via the 'styles' option in configuration, where you define custom classes for elements like rd-container or rd-day-selected. Override the default styles object from the README to match your design system.

Rome vs Flatpickr: which is better?

Rome is more customizable and doesn't depend on jQuery, but it requires moment.js, adding bundle size. Flatpickr is lighter with no dependencies but may be less flexible. Choose Rome for deep customization and legacy browser support, or Flatpickr for simpler, modern projects.

How to use Rome with React?

Rome isn't built for React, so you need a wrapper component that initializes Rome on a ref or DOM element. Handle lifecycle events like componentDidMount to create the instance and componentWillUnmount to destroy it, avoiding memory leaks.

Does Rome support date range selection?

No, Rome is designed for single date and time picking only. For date ranges, you must use two Rome instances or consider alternative libraries like flatpickr or airbnb/react-dates that offer native range UIs.

How to validate dates in Rome?

Use built-in validators like min/max options or custom dateValidator/timeValidator functions. Rome also provides validator factories like rome.val.after() or rome.val.except() for common patterns, as detailed in the API section.

Can Rome be used as an inline calendar?

Yes, pass a non-input element to rome() to create an inline calendar. Options like autoHideOnBlur are ignored, and the calendar is appended directly to the element, making it ideal for dashboards or widgets.

The library solves the problem of integrating a lightweight, styleable calendar without relying on heavy frameworks like jQuery.

Target Audience

Frontend developers and web designers who need a customizable, lightweight date/time picker for forms or interactive applications. It's ideal for projects where design control and performance are priorities.

Overview

:calendar: Customizable date (and time) picker. Opt-in UI, no jQuery!

Use Cases

Best For

Adding date pickers to forms without jQuery
Building custom calendar interfaces with unique styling
Implementing date and time selection with validation rules
Creating inline calendars for dashboards or widgets
Supporting legacy browsers like IE7+ with modern picker features
Projects needing lightweight, dependency-free UI components

Not Ideal For

Projects requiring multi-date or date-range selection UIs, as Rome focuses on single date/time picking
Applications where minimizing JavaScript bundle size is critical, due to the mandatory inclusion of moment.js
Teams using modern frontend frameworks like React or Vue who prefer component libraries with built-in integrations
New projects targeting only modern browsers, as Rome's legacy support for IE7+ might add unnecessary complexity

Pros & Cons

Pros

Extensive Customization Options

The library provides fully customizable CSS classes and numerous layout options through the 'styles' configuration, allowing seamless integration into any design system.

Seamless Input Integration

Rome synchronizes in real-time with input fields without stealing focus, ensuring a smooth user experience as highlighted in the README's feature list.

Broad Browser Compatibility

Supports IE7+ and all modern browsers, making it a reliable choice for applications with diverse user bases, as stated in the browser support section.

Flexible Date Handling

Offers configurable date and time picking with built-in validators and constraints, such as min/max limits and custom validation functions, providing robust logic out of the box.

Cons

Dependence on Legacy Library

Rome depends on moment.js, a large, legacy date library that increases bundle size and may not align with modern project dependencies, as admitted in the README's setup notes.

Complex Configuration Overhead

With over 20 configuration options and a detailed API, setting up Rome can be overwhelming for simple use cases, requiring significant time to understand all features like validators and event hooks.

Limited Framework Support

Not designed for integration with popular frameworks like React or Vue, necessitating manual wrapper components and additional setup, which can lead to maintenance challenges.
