util-nonempty^5.0.29

Installation

Quick Take

Purpose

It is a quick utility function, to be able to detect is the input not empty.

• null, unefined yields false
• any number (incl. zero) yields true
• any array or string with length > 0 yields true, otherwise false
• plain objects with at least one key yields true, otherwise false
• all other types yield false

If you want to check non-emptiness of complex nested trees of objects, arrays and strings (like parsed HTML AST), you need a library which can recursively traverse that. There are two options:

• If you want to check for strict emptiness, that is [] or {} is empty, but {aaa: ' \n\n\n ', ' \t'} is not, see ast-is-empty
• If your “emptiness” definition is “everything that String.trim()’s to an empty string’” (this includes tabs, spaces and line breaks for example, but not letters), see ast-contains-only-empty-space, or plain objects without keys or zero-length arrays.
