upath v2.0.1
A drop-in replacement / proxy to nodejs's path
that:
-
Replaces the windows
\
with the unix/
in all string params & results. This has significant positives - see below. -
Adds filename extensions functions
addExt
,trimExt
,removeExt
,changeExt
, anddefaultExt
. -
Add a
normalizeSafe
function to preserve any meaningful leading./
& anormalizeTrim
which additionally trims any useless ending/
. -
Plus a helper
toUnix
that simply converts\
to/
and consolidates duplicates.
Useful note: these docs are actually auto generated from specs, running on Linux.
Notes:
-
upath.sep
is set to'/'
for seamless replacement (as of 1.0.3). -
upath has no runtime dependencies, except built-in
path
(as of 1.0.4) -
travis-ci tested in node versions 8 to 14 (on linux)
-
Also tested on Windows / node@12.18.0 (without CI)
History brief:
-
1.x : Initial release and various features / fixes
-
2.0.0 : Adding UNC paths support - see https://github.com/anodynos/upath/pull/38
Why ?
Normal path
doesn't convert paths to a unified format (ie /
) before calculating paths (normalize
, join
), which can lead to numerous problems.
Also path joining, normalization etc on the two formats is not consistent, depending on where it runs. Running path
on Windows yields different results than when it runs on Linux / Mac.
In general, if you code your paths logic while developing on Unix/Mac and it runs on Windows, you may run into problems when using path
.
Note that using Unix /
on Windows works perfectly inside nodejs (and other languages), so there's no reason to stick to the Windows legacy at all.
Examples / specs
Check out the different (improved) behavior to vanilla path
:
`upath.normalize(path)` --returns-->
✓ `'c:/windows/nodejs/path'` ---> `'c:/windows/nodejs/path'` // equal to `path.normalize()`
✓ `'c:/windows/../nodejs/path'` ---> `'c:/nodejs/path'` // equal to `path.normalize()`
✓ `'c:\\windows\\nodejs\\path'` ---> `'c:/windows/nodejs/path'` // `path.normalize()` gives `'c:\windows\nodejs\path'`
✓ `'c:\\windows\\..\\nodejs\\path'` ---> `'c:/nodejs/path'` // `path.normalize()` gives `'c:\windows\..\nodejs\path'`
✓ `'/windows\\unix/mixed'` ---> `'/windows/unix/mixed'` // `path.normalize()` gives `'/windows\unix/mixed'`
✓ `'\\windows//unix/mixed'` ---> `'/windows/unix/mixed'` // `path.normalize()` gives `'\windows/unix/mixed'`
✓ `'\\windows\\..\\unix/mixed/'` ---> `'/unix/mixed/'` // `path.normalize()` gives `'\windows\..\unix/mixed/'`
Joining paths can also be a problem:
`upath.join(paths...)` --returns-->
✓ `'some/nodejs/deep', '../path'` ---> `'some/nodejs/path'` // equal to `path.join()`
✓ `'some/nodejs\\windows', '../path'` ---> `'some/nodejs/path'` // `path.join()` gives `'some/path'`
✓ `'some\\windows\\only', '..\\path'` ---> `'some/windows/path'` // `path.join()` gives `'some\windows\only/..\path'`
Parsing with path.parse()
should also be consistent across OSes:
upath.parse(path)
--returns-->
✓ `'c:\Windows\Directory\somefile.ext'` ---> `{ root: '', dir: 'c:/Windows/Directory', base: 'somefile.ext', ext: '.ext', name: 'somefile'
}//
path.parse()gives
'{ root: '', dir: '', base: 'c:\Windows\Directory\somefile.ext', ext: '.ext', name: 'c:\Windows\Directory\somefile'
}'✓
'/root/of/unix/somefile.ext'--->
{ root: '/', dir: '/root/of/unix', base: 'somefile.ext', ext: '.ext', name: 'somefile'
}// equal to
path.parse()`
Added functions
upath.toUnix(path)
Just converts all `` to /
and consolidates duplicates, without performing any normalization.
Examples / specs
`upath.toUnix(path)` --returns-->
✓ `'.//windows\//unix//mixed////'` ---> `'./windows/unix/mixed/'`
✓ `'..///windows\..\\unix/mixed'` ---> `'../windows/../unix/mixed'`
upath.normalizeSafe(path)
Exactly like path.normalize(path)
, but it keeps the first meaningful ./
or //
.
Note that the unix /
is returned everywhere, so windows \
is always converted to unix /
.

Added functions for filename extension manipulation.
Happy notes:
In all functions you can:
-
use both
.ext
&ext
- the dot.
on the extension is always adjusted correctly. -
omit the
ext
param (pass null/undefined/empty string) and the common sense thing will happen. -
ignore specific extensions from being considered as valid ones (eg
.min
,.dev
.aLongExtIsNotAnExt
etc), hence no trimming or replacement takes place on them.
upath.addExt(filename, [ext])
Adds .ext
to filename
, but only if it doesn't already have the exact extension.
Examples / specs
`upath.addExt(filename, 'js')` --returns-->
✓ `'myfile/addExt'` ---> `'myfile/addExt.js'`
✓ `'myfile/addExt.txt'` ---> `'myfile/addExt.txt.js'`
✓ `'myfile/addExt.js'` ---> `'myfile/addExt.js'`
✓ `'myfile/addExt.min.'` ---> `'myfile/addExt.min..js'`
It adds nothing if no ext
param is passed.
`upath.addExt(filename)` --returns-->
✓ `'myfile/addExt'` ---> `'myfile/addExt'`
✓ `'myfile/addExt.txt'` ---> `'myfile/addExt.txt'`
✓ `'myfile/addExt.js'` ---> `'myfile/addExt.js'`
✓ `'myfile/addExt.min.'` ---> `'myfile/addExt.min.'`
upath.trimExt(filename, [ignoreExts], [maxSize=7])
Trims a filename's extension.
-
Extensions are considered to be up to
maxSize
chars long, counting the dot (defaults to 7). -
An
Array
ofignoreExts
(eg['.min']
) prevents these from being considered as extension, thus are not trimmed.
Examples / specs
`upath.trimExt(filename)` --returns-->
✓ `'my/trimedExt.txt'` ---> `'my/trimedExt'`
✓ `'my/trimedExt'` ---> `'my/trimedExt'`
✓ `'my/trimedExt.min'` ---> `'my/trimedExt'`
✓ `'my/trimedExt.min.js'` ---> `'my/trimedExt.min'`
✓ `'../my/trimedExt.longExt'` ---> `'../my/trimedExt.longExt'`
It is ignoring .min
& .dev
as extensions, and considers exts with up to 8 chars.
`upath.trimExt(filename, ['min', '.dev'], 8)` --returns-->
✓ `'my/trimedExt.txt'` ---> `'my/trimedExt'`
✓ `'my/trimedExt.min'` ---> `'my/trimedExt.min'`
✓ `'my/trimedExt.dev'` ---> `'my/trimedExt.dev'`
✓ `'../my/trimedExt.longExt'` ---> `'../my/trimedExt'`
✓ `'../my/trimedExt.longRExt'` ---> `'../my/trimedExt.longRExt'`
upath.removeExt(filename, ext)
Removes the specific ext
extension from filename, if it has it. Otherwise it leaves it as is.
As in all upath functions, it be .ext
or ext
.
Examples / specs
`upath.removeExt(filename, '.js')` --returns-->
✓ `'removedExt.js'` ---> `'removedExt'`
✓ `'removedExt.txt.js'` ---> `'removedExt.txt'`
✓ `'notRemoved.txt'` ---> `'notRemoved.txt'`
It does not care about the length of exts.
`upath.removeExt(filename, '.longExt')` --returns-->
✓ `'removedExt.longExt'` ---> `'removedExt'`
✓ `'removedExt.txt.longExt'` ---> `'removedExt.txt'`
✓ `'notRemoved.txt'` ---> `'notRemoved.txt'`
upath.changeExt(filename, [ext], [ignoreExts], [maxSize=7])
Changes a filename's extension to ext
. If it has no (valid) extension, it adds it.
-
Valid extensions are considered to be up to
maxSize
chars long, counting the dot (defaults to 7). -
An
Array
ofignoreExts
(eg['.min']
) prevents these from being considered as extension, thus are not changed - the new extension is added instead.
Examples / specs
`upath.changeExt(filename, '.js')` --returns-->
✓ `'my/module.min'` ---> `'my/module.js'`
✓ `'my/module.coffee'` ---> `'my/module.js'`
✓ `'my/module'` ---> `'my/module.js'`
✓ `'file/withDot.'` ---> `'file/withDot.js'`
✓ `'file/change.longExt'` ---> `'file/change.longExt.js'`
If no ext
param is given, it trims the current extension (if any).
`upath.changeExt(filename)` --returns-->
✓ `'my/module.min'` ---> `'my/module'`
✓ `'my/module.coffee'` ---> `'my/module'`
✓ `'my/module'` ---> `'my/module'`
✓ `'file/withDot.'` ---> `'file/withDot'`
✓ `'file/change.longExt'` ---> `'file/change.longExt'`
It is ignoring .min
& .dev
as extensions, and considers exts with up to 8 chars.
`upath.changeExt(filename, 'js', ['min', '.dev'], 8)` --returns-->
✓ `'my/module.coffee'` ---> `'my/module.js'`
✓ `'file/notValidExt.min'` ---> `'file/notValidExt.min.js'`
✓ `'file/notValidExt.dev'` ---> `'file/notValidExt.dev.js'`
✓ `'file/change.longExt'` ---> `'file/change.js'`
✓ `'file/change.longRExt'` ---> `'file/change.longRExt.js'`
upath.defaultExt(filename, [ext], [ignoreExts], [maxSize=7])
Adds .ext
to filename
, only if it doesn't already have any old extension.
-
(Old) extensions are considered to be up to
maxSize
chars long, counting the dot (defaults to 7). -
An
Array
ofignoreExts
(eg['.min']
) will force adding default.ext
even if one of these is present.
Examples / specs
`upath.defaultExt(filename, 'js')` --returns-->
✓ `'fileWith/defaultExt'` ---> `'fileWith/defaultExt.js'`
✓ `'fileWith/defaultExt.js'` ---> `'fileWith/defaultExt.js'`
✓ `'fileWith/defaultExt.min'` ---> `'fileWith/defaultExt.min'`
✓ `'fileWith/defaultExt.longExt'` ---> `'fileWith/defaultExt.longExt.js'`
If no ext
param is passed, it leaves filename intact.
`upath.defaultExt(filename)` --returns-->
✓ `'fileWith/defaultExt'` ---> `'fileWith/defaultExt'`
✓ `'fileWith/defaultExt.js'` ---> `'fileWith/defaultExt.js'`
✓ `'fileWith/defaultExt.min'` ---> `'fileWith/defaultExt.min'`
✓ `'fileWith/defaultExt.longExt'` ---> `'fileWith/defaultExt.longExt'`
It is ignoring .min
& .dev
as extensions, and considers exts with up to 8 chars.
`upath.defaultExt(filename, 'js', ['min', '.dev'], 8)` --returns-->
✓ `'fileWith/defaultExt'` ---> `'fileWith/defaultExt.js'`
✓ `'fileWith/defaultExt.min'` ---> `'fileWith/defaultExt.min.js'`
✓ `'fileWith/defaultExt.dev'` ---> `'fileWith/defaultExt.dev.js'`
✓ `'fileWith/defaultExt.longExt'` ---> `'fileWith/defaultExt.longExt'`
✓ `'fileWith/defaultExt.longRext'` ---> `'fileWith/defaultExt.longRext.js'`
