Npm Calendar Libraries

When are Calendar Libraries Useful

Calendar libraries are quite useful in numerous scenarios and applications. When building a web application that requires any form of date or time-related functionality, calendar libraries can be beneficial.

• Scheduling and planning apps: If your web application involves scheduling or allotting time slots, a calendar library would be optimal. An instance of this may be an appointment scheduling system.

• Task Management: For tracking due dates and deadlines, the integration of a calendar library in a task management application offers easiness and precision.

• Event Planning: If your application hosts events or facilitates event planning, calendar libraries will streamline the selection of dates and times.

• Analytics: In applications that require tracking or presenting data over time, calendar libraries make the display of time-series data much cleaner.

What Functionalities do Calendar Libraries Usually Have

Calendar libraries offer an array of functionalities that eases the task of date and time handling and manipulation.

• Date Selection: The key functionality of any calendar library is to enable users to select or input dates.

• Time Selection: Along with dates, libraries typically feature time selection as well.

• Multi-view: Most calendar libraries provide different views like day view, week view, month view and year view.

• Event Handling: Calendar Libraries often provide the feature to add events or tasks to specific dates.

• Customisability: These libraries often offer customisation options like start-of-week day, locale, minimal and maximum dates, marking holidays, and styling options.

• Timezone Support: Most calendar libraries will offer robust support for various time zones, an essential feature for global applications.

Gotchas/Pitfalls to Look Out For

Despite the ease and functionality that calendar libraries offer, there are a few potential gotchas or pitfalls that developers might want to watch out for.

• Size: Some calendar libraries might be quite large and can potentially make your JavaScript bundle bloated, slowing down your application. Ensure to check the size of the libraries when using npm.

• Deprecation: As libraries are constantly updated, some functionalities might become deprecated. Using newer or non-maintained libraries could result in potential deprecation issues. Always verify the library's update and maintenance status.

• Timezone Issues: Although many libraries promise robust timezone support, ensuring this functionality meets your specific needs is crucial. Issues around daylight saving times are particularly common.

• Dependency Risk: Adding a third-party library increases your dependency risk as it might introduce bugs and you are relying on that library's team to fix those issues.

• Complicated API: Some calendar libraries might have a complicated API or might not be well-documented. This can increase the learning curve and development time.

Through npm, you can easily check a package's size, number of dependencies, and maintenance status, and choose a package that's actively maintained, well-documented, and fits your software's requirements.
