remove-trailing-separator

What is remove-trailing-separator?

The remove-trailing-separator npm package is a simple utility that helps in removing trailing separators from a given path string. This can be particularly useful in file path manipulations where consistency in path formatting is required.

What are remove-trailing-separator's main functionalities?

Remove trailing path separator

This feature allows the removal of trailing slashes (or other relevant separators) from a file path. It ensures that the path is normalized without an ending separator, which is useful for concatenating paths or when directories are compared.

const removeTrailingSeparator = require('remove-trailing-separator');
console.log(removeTrailingSeparator('example/path/')); // Outputs: 'example/path'

Other packages similar to remove-trailing-separator

normalize-path

normalize-path is similar to remove-trailing-separator but offers broader functionality including the normalization of path strings by removing unnecessary slashes and resolving '.' and '..' segments. Unlike remove-trailing-separator, which only removes the trailing separator, normalize-path adjusts the entire path structure.

slash

The slash package converts Windows backslash paths to slash paths, which is somewhat related but not identical to remove-trailing-separator. While slash changes the type of separators, remove-trailing-separator specifically focuses on removing unnecessary trailing separators.

Install

npm install remove-trailing-separator

Examples

const removeTrailingSeparator = require('remove-trailing-separator');

removeTrailingSeparator('/foo/bar/')   // '/foo/bar'
removeTrailingSeparator('/foo/bar///') // '/foo/bar'

// leaves only/last separator
removeTrailingSeparator('/')    // '/'
removeTrailingSeparator('///')  // '/'

// returns empty string
removeTrailingSeparator('') // ''

Notable backslash, or win32 separator behavior

\ is considered a separator only on WIN32 systems. All POSIX compliant systems see backslash as a valid file name character, so it would break POSIX compliance to remove it there.

In practice, this means that this code will return different things depending on what system it runs on:

removeTrailingSeparator('\\foo\\')
// UNIX  => '\\foo\\'
// WIN32 => '\\foo'
