Question 1

Fecha vs date-fns for date formatting?

Accepted Answer

Fecha is better if you only need formatting and parsing with a tiny footprint (~2KB), while date-fns offers modular date manipulation but larger size. For pure formatting, Fecha's minimalism is ideal.

Question 2

How to parse a date string without knowing the format in Fecha?

Accepted Answer

Fecha requires specifying the format for parsing; it doesn't support automatic detection. You'll need to know the format beforehand or use a different library with inference capabilities.

Question 3

Does Fecha handle timezone conversions?

Accepted Answer

Fecha only supports timezone formatting with tokens like 'Z' for offset display, but it doesn't provide timezone conversion or manipulation. For that, consider libraries like Luxon.

Question 4

What are the default named masks in Fecha?

Accepted Answer

Fecha includes predefined masks like 'shortDate' (M/D/YY), 'mediumDate' (MMM D, YYYY), and 'isoDateTime', which you can use directly or override with setGlobalDateMasks.

Question 5

Is Fecha still maintained and safe to use?

Accepted Answer

The README shows a Travis CI build status, but check GitHub for recent activity. It's a stable, narrow-scope library, so updates may be infrequent but it's reliable for its purpose.

Question 6

How to format dates in Spanish with Fecha?

Accepted Answer

Use setGlobalDateI18n to override labels with Spanish arrays for monthNames and dayNames. For example, provide Spanish names like 'enero' for January to localize outputs.
