Match files using the patterns the shell uses.
The most correct and second fastest glob implementation in JavaScript. (See Comparison to Other JavaScript Glob Implementations at the bottom of this readme.)
Install with npm
npm i glob
Note the npm package name is not node-glob that's a
different thing that was abandoned years ago. Just glob.
// load using import
import { glob, globSync, globStream, globStreamSync, Glob } from 'glob'
// or using commonjs, that's fine, too
const {
glob,
globSync,
globStream,
globStreamSync,
Glob,
} = require('glob')
// the main glob() and globSync() resolve/return array of filenames
// all js files, but don't look in node_modules
const jsfiles = await glob('**/*.js', { ignore: 'node_modules/**' })
// pass in a signal to cancel the glob walk
const stopAfter100ms = await glob('**/*.css', {
signal: AbortSignal.timeout(100),
})
// multiple patterns supported as well
const images = await glob(['css/*.{png,jpeg}', 'public/*.{png,jpeg}'])
// but of course you can do that with the glob pattern also
// the sync function is the same, just returns a string[] instead
// of Promise<string[]>
const imagesAlt = globSync('{css,public}/*.{png,jpeg}')
// you can also stream them, this is a Minipass stream
const filesStream = globStream(['**/*.dat', 'logs/**/*.log'])
// construct a Glob object if you wanna do it that way, which
// allows for much faster walks if you have to look in the same
// folder multiple times.
const g = new Glob('**/foo', {})
// glob objects are async iterators, can also do globIterate() or
// g.iterate(), same deal
for await (const file of g) {
console.log('found a foo file:', file)
}
// pass a glob as the glob options to reuse its settings and caches
const g2 = new Glob('**/bar', g)
// sync iteration works as well
for (const file of g2) {
console.log('found a bar file:', file)
}
// you can also pass withFileTypes: true to get Path objects
// these are like a Dirent, but with some more added powers
// check out http://npm.im/path-scurry for more info on their API
const g3 = new Glob('**/baz/**', { withFileTypes: true })
g3.stream().on('data', path => {
console.log(
'got a path object',
path.fullpath(),
path.isDirectory(),
path.readdirSync().map(e => e.name),
)
})
// if you use stat:true and withFileTypes, you can sort results
// by things like modified time, filter by permission mode, etc.
// All Stats fields will be available in that case. Slightly
// slower, though.
// For example:
const results = await glob('**', { stat: true, withFileTypes: true })
const timeSortedFiles = results
.sort((a, b) => a.mtimeMs - b.mtimeMs)
.map(path => path.fullpath())
const groupReadableFiles = results
.filter(path => path.mode & 0o040)
.map(path => path.fullpath())
// custom ignores can be done like this, for example by saying
// you'll ignore all markdown files, and all folders named 'docs'
const customIgnoreResults = await glob('**', {
ignore: {
ignored: p => /\.md$/.test(p.name),
childrenIgnored: p => p.isNamed('docs'),
},
})
// another fun use case, only return files with the same name as
// their parent folder, plus either `.ts` or `.js`
const folderNamedModules = await glob('**/*.{ts,js}', {
ignore: {
ignored: p => {
const pp = p.parent
return !(p.isNamed(pp.name + '.ts') || p.isNamed(pp.name + '.js'))
},
},
})
// find all files edited in the last hour, to do this, we ignore
// all of them that are more than an hour old
const newFiles = await glob('**', {
// need stat so we have mtime
stat: true,
// only want the files, not the dirs
nodir: true,
ignore: {
ignored: p => {
return new Date() - p.mtime > 60 * 60 * 1000
},
// could add similar childrenIgnored here as well, but
// directory mtime is inconsistent across platforms, so
// probably better not to, unless you know the system
// tracks this reliably.
},
})Note Glob patterns should always use / as a path separator,
even on Windows systems, as \ is used to escape glob
characters. If you wish to use \ as a path separator instead
of using it as an escape character on Windows platforms, you may
set windowsPathsNoEscape:true in the options. In this mode,
special glob characters cannot be escaped, making it impossible
to match a literal * ? and so on in filenames.
$ glob -h
Usage:
glob [options] [<pattern> [<pattern> ...]]
Expand the positional glob expression arguments into any matching file system
paths found.
-c<command> --cmd=<command>
Run the command provided, passing the glob expression
matches as arguments.
-A --all By default, the glob cli command will not expand any
arguments that are an exact match to a file on disk.
This prevents double-expanding, in case the shell
expands an argument whose filename is a glob
expression.
For example, if 'app/*.ts' would match 'app/[id].ts',
then on Windows powershell or cmd.exe, 'glob app/*.ts'
will expand to 'app/[id].ts', as expected. However, in
posix shells such as bash or zsh, the shell will first
expand 'app/*.ts' to a list of filenames. Then glob
will look for a file matching 'app/[id].ts' (ie,
'app/i.ts' or 'app/d.ts'), which is unexpected.
Setting '--all' prevents this behavior, causing glob to
treat ALL patterns as glob expressions to be expanded,
even if they are an exact match to a file on disk.
When setting this option, be sure to enquote arguments
so that the shell will not expand them prior to passing
them to the glob command process.
-a --absolute Expand to absolute paths
-d --dot-relative Prepend './' on relative matches
-m --mark Append a / on any directories matched
-x --posix Always resolve to posix style paths, using '/' as the
directory separator, even on Windows. Drive letter
absolute matches on Windows will be expanded to their
full resolved UNC maths, eg instead of 'C:\foo\bar', it
will expand to '//?/C:/foo/bar'.
-f --follow Follow symlinked directories when expanding '**'
-R --realpath Call 'fs.realpath' on all of the results. In the case
of an entry that cannot be resolved, the entry is
omitted. This incurs a slight performance penalty, of
course, because of the added system calls.
-s --stat Call 'fs.lstat' on all entries, whether required or not
to determine if it's a valid match.
-b --match-base Perform a basename-only match if the pattern does not
contain any slash characters. That is, '*.js' would be
treated as equivalent to '**/*.js', matching js files
in all directories.
--dot Allow patterns to match files/directories that start
with '.', even if the pattern does not start with '.'
--nobrace Do not expand {...} patterns
--nocase Perform a case-insensitive match. This defaults to
'true' on macOS and Windows platforms, and false on all
others.
Note: 'nocase' should only be explicitly set when it is
known that the filesystem's case sensitivity differs
from the platform default. If set 'true' on
case-insensitive file systems, then the walk may return
more or less results than expected.
--nodir Do not match directories, only files.
Note: to *only* match directories, append a '/' at the
end of the pattern.
--noext Do not expand extglob patterns, such as '+(a|b)'
--noglobstar Do not expand '**' against multiple path portions. Ie,
treat it as a normal '*' instead.
--windows-path-no-escape
Use '\' as a path separator *only*, and *never* as an
escape character. If set, all '\' characters are
replaced with '/' in the pattern.
-D<n> --max-depth=<n> Maximum depth to traverse from the current working
directory
-C<cwd> --cwd=<cwd> Current working directory to execute/match in
-r<root> --root=<root> A string path resolved against the 'cwd', which is used
as the starting point for absolute patterns that start
with '/' (but not drive letters or UNC paths on
Windows).
Note that this *doesn't* necessarily limit the walk to
the 'root' directory, and doesn't affect the cwd
starting point for non-absolute patterns. A pattern
containing '..' will still be able to traverse out of
the root directory, if it is not an actual root
directory on the filesystem, and any non-absolute
patterns will still be matched in the 'cwd'.
To start absolute and non-absolute patterns in the same
path, you can use '--root=' to set it to the empty
string. However, be aware that on Windows systems, a
pattern like 'x:/*' or '//host/share/*' will *always*
start in the 'x:/' or '//host/share/' directory,
regardless of the --root setting.
--platform=<platform> Defaults to the value of 'process.platform' if
available, or 'linux' if not. Setting --platform=win32
on non-Windows systems may cause strange behavior!
-i<ignore> --ignore=<ignore>
Glob patterns to ignore Can be set multiple times
-v --debug Output a huge amount of noisy debug information about
patterns as they are parsed and used to match files.
-h --help Show this usage information
Perform an asynchronous glob search for the pattern(s) specified.
Returns
Path
objects if the withFileTypes option is set to true. See below
for full options field desciptions.
Synchronous form of glob().
Alias: glob.sync()
Return an async iterator for walking glob pattern matches.
Alias: glob.iterate()
Return a sync iterator for walking glob pattern matches.
Alias: glob.iterate.sync(), glob.sync.iterate()
Return a stream that emits all the strings or Path objects and
then emits end when completed.
Alias: glob.stream()
Syncronous form of globStream(). Will read all the matches as
fast as you consume them, even all in a single tick if you
consume them immediately, but will still respond to backpressure
if they're not consumed immediately.
Alias: glob.stream.sync(), glob.sync.stream()
Returns true if the provided pattern contains any "magic" glob
characters, given the options provided.
Brace expansion is not considered "magic" unless the
magicalBraces option is set, as brace expansion just turns one
string into an array of strings. So a pattern like 'x{a,b}y'
would return false, because 'xay' and 'xby' both do not
contain any magic glob characters, and it's treated the same as
if you had called it on ['xay', 'xby']. When
magicalBraces:true is in the options, brace expansion is
treated as a pattern having magic.
Escape all magic characters in a glob pattern, so that it will only ever match literal strings
If the windowsPathsNoEscape option is used, then characters are
escaped by wrapping in [], because a magic character wrapped in
a character class can only be satisfied by that exact character.
Slashes (and backslashes in windowsPathsNoEscape mode) cannot
be escaped or unescaped.
Un-escape a glob string that may contain some escaped characters.
If the windowsPathsNoEscape option is used, then square-brace
escapes are removed, but not backslash escapes. For example, it
will turn the string '[*]' into *, but it will not turn
'\\*' into '*', because \ is a path separator in
windowsPathsNoEscape mode.
When windowsPathsNoEscape is not set, then both brace escapes
and backslash escapes are removed.
Slashes (and backslashes in windowsPathsNoEscape mode) cannot
be escaped or unescaped.
An object that can perform glob pattern traversals.
Options object is required.
See full options descriptions below.
Note that a previous Glob object can be passed as the
GlobOptions to another Glob instantiation to re-use settings
and caches with a new pattern.
Traversal functions can be called multiple times to run the walk again.
Stream results asynchronously,
Stream results synchronously.
Default async iteration function. Returns an AsyncGenerator that iterates over the results.
Default sync iteration function. Returns a Generator that iterates over the results.
Returns a Promise that resolves to the results array.
Returns a results array.
All options are stored as properties on the Glob object.
optsThe options provided to the constructor.patternsAn array of parsed immutablePatternobjects.
Exported as GlobOptions TypeScript interface. A GlobOptions
object may be provided to any of the exported methods, and must
be provided to the Glob constructor.
All options are optional, boolean, and false by default, unless otherwise noted.
All resolved options are added to the Glob object as properties.
If you are running many glob operations, you can pass a Glob
object as the options argument to a subsequent operation to
share the previously loaded cache.
-
cwdString path orfile://string or URL object. The current working directory in which to search. Defaults toprocess.cwd(). See also: "Windows, CWDs, Drive Letters, and UNC Paths", below.This option may be either a string path or a
file://URL object or string. -
rootA string path resolved against thecwdoption, which is used as the starting point for absolute patterns that start with/, (but not drive letters or UNC paths on Windows).Note that this doesn't necessarily limit the walk to the
rootdirectory, and doesn't affect the cwd starting point for non-absolute patterns. A pattern containing..will still be able to traverse out of the root directory, if it is not an actual root directory on the filesystem, and any non-absolute patterns will be matched in thecwd. For example, the pattern/../*with{root:'/some/path'}will return all files in/some, not all files in/some/path. The pattern*with{root:'/some/path'}will return all the entries in the cwd, not the entries in/some/path.To start absolute and non-absolute patterns in the same path, you can use
{root:''}. However, be aware that on Windows systems, a pattern likex:/*or//host/share/*will always start in thex:/or//host/sharedirectory, regardless of therootsetting. -
windowsPathsNoEscapeUse\\as a path separator only, and never as an escape character. If set, all\\characters are replaced with/in the pattern.Note that this makes it impossible to match against paths containing literal glob pattern characters, but allows matching with patterns constructed using
path.join()andpath.resolve()on Windows platforms, mimicking the (buggy!) behavior of Glob v7 and before on Windows. Please use with caution, and be mindful of the caveat below about Windows paths. (For legacy reasons, this is also set ifallowWindowsEscapeis set to the exact valuefalse.) -
dotInclude.dotfiles in normal matches andglobstarmatches. Note that an explicit dot in a portion of the pattern will always match dot files. -
magicalBracesTreat brace expansion like{a,b}as a "magic" pattern. Has no effect if {@link nobrace} is set.Only has effect on the {@link hasMagic} function, no effect on glob pattern matching itself.
-
dotRelativePrepend all relative path strings with./(or.\on Windows).Without this option, returned relative paths are "bare", so instead of returning
'./foo/bar', they are returned as'foo/bar'.Relative patterns starting with
'../'are not prepended with./, even if this option is set. -
markAdd a/character to directory matches. Note that this requires additional stat calls. -
nobraceDo not expand{a,b}and{1..3}brace sets. -
noglobstarDo not match**against multiple filenames. (Ie, treat it as a normal*instead.) -
noextDo not match "extglob" patterns such as+(a|b). -
nocasePerform a case-insensitive match. This defaults totrueon macOS and Windows systems, andfalseon all others.Note
nocaseshould only be explicitly set when it is known that the filesystem's case sensitivity differs from the platform default. If settrueon case-sensitive file systems, orfalseon case-insensitive file systems, then the walk may return more or less results than expected. -
maxDepthSpecify a number to limit the depth of the directory traversal to this many levels below thecwd. -
matchBasePerform a basename-only match if the pattern does not contain any slash characters. That is,*.jswould be treated as equivalent to**/*.js, matching all js files in all directories. -
nodirDo not match directories, only files. (Note: to match only directories, put a/at the end of the pattern.)Note: when
followandnodirare both set, then symbolic links to directories are also omitted. -
statCalllstat()on all entries, whether required or not to determine whether it's a valid match. When used withwithFileTypes, this means that matches will include data such as modified time, permissions, and so on. Note that this will incur a performance cost due to the added system calls. -
ignorestring or string[], or an object withignoreandignoreChildrenmethods.If a string or string[] is provided, then this is treated as a glob pattern or array of glob patterns to exclude from matches. To ignore all children within a directory, as well as the entry itself, append
'/**'to the ignore pattern.Note
ignorepatterns are always indot:truemode, regardless of any other settings.If an object is provided that has
ignored(path)and/orchildrenIgnored(path)methods, then these methods will be called to determine whether any Path is a match or if its children should be traversed, respectively. -
followFollow symlinked directories when expanding**patterns. This can result in a lot of duplicate references in the presence of cyclic links, and make performance quite bad.By default, a
**in a pattern will follow 1 symbolic link if it is not the first item in the pattern, or none if it is the first item in the pattern, following the same behavior as Bash.Note: when
followandnodirare both set, then symbolic links to directories are also omitted. -
realpathSet to true to callfs.realpathon all of the results. In the case of an entry that cannot be resolved, the entry is omitted. This incurs a slight performance penalty, of course, because of the added system calls. -
absoluteSet to true to always receive absolute paths for matched files. Set tofalseto always receive relative paths for matched files.By default, when this option is not set, absolute paths are returned for patterns that are absolute, and otherwise paths are returned that are relative to the
cwdsetting.This does not make an extra system call to get the realpath, it only does string path resolution.
absolutemay not be used along withwithFileTypes. -
posixSet to true to use/as the path separator in returned results. On posix systems, this has no effect. On Windows systems, this will return/delimited path results, and absolute paths will be returned in their full resolved UNC path form, eg insted of'C:\\foo\\bar', it will return//?/C:/foo/bar. -
platformDefaults to value ofprocess.platformif available, or'linux'if not. Settingplatform:'win32'on non-Windows systems may cause strange behavior. -
withFileTypesReturn PathScurryPathobjects instead of strings. These are similar to a NodeJSDirentobject, but with additional methods and properties.withFileTypesmay not be used along withabsolute. -
signalAn AbortSignal which will cancel the Glob walk when triggered. -
fsAn override object to pass in custom filesystem methods. See PathScurry docs for what can be overridden. -
scurryA PathScurry object used to traverse the file system. If thenocaseoption is set explicitly, then any providedscurryobject must match this setting. -
includeChildMatchesboolean, defaulttrue. Do not match any children of any matches. For example, the pattern**\/foowould matcha/foo, but nota/foo/b/fooin this mode.This is especially useful for cases like "find all
node_modulesfolders, but not the ones innode_modules".In order to support this, the
Ignoreimplementation must support anadd(pattern: string)method. If using the defaultIgnoreclass, then this is fine, but if this is set tofalse, and a customIgnoreis provided that does not have anadd()method, then it will throw an error.Caveat It only ignores matches that would be a descendant of a previous match, and only if that descendant is matched after the ancestor is encountered. Since the file system walk happens in indeterminate order, it's possible that a match will already be added before its ancestor, if multiple or braced patterns are used.
For example:
const results = await glob( [ // likely to match first, since it's just a stat 'a/b/c/d/e/f', // this pattern is more complicated! It must to various readdir() // calls and test the results against a regular expression, and that // is certainly going to take a little bit longer. // // So, later on, it encounters a match at 'a/b/c/d/e', but it's too // late to ignore a/b/c/d/e/f, because it's already been emitted. 'a/[bdf]/?/[a-z]/*', ], { includeChildMatches: false }, )
It's best to only set this to
falseif you can be reasonably sure that no components of the pattern will potentially match one another's file system descendants, or if the occasional included child entry will not cause problems.
Much more information about glob pattern expansion can be found
by running man bash and searching for Pattern Matching.
"Globs" are the patterns you type when you do stuff like ls *.js on the command line, or put build/* in a .gitignore
file.
Before parsing the path part patterns, braced sections are
expanded into a set. Braced sections start with { and end with
}, with 2 or more comma-delimited sections within. Braced
sections may contain slash characters, so a{/b/c,bcd} would
expand into a/b/c and abcd.
The following characters have special magic meaning when used in
a path portion. With the exception of **, none of these match
path separators (ie, / on all platforms, and \ on Windows).
*Matches 0 or more characters in a single path portion. When alone in a path portion, it must match at least 1 character. Ifdot:trueis not specified, then*will not match against a.character at the start of a path portion.?Matches 1 character. Ifdot:trueis not specified, then?will not match against a.character at the start of a path portion.[...]Matches a range of characters, similar to a RegExp range. If the first character of the range is!or^then it matches any character not in the range. If the first character is], then it will be considered the same as\], rather than the end of the character class.!(pattern|pattern|pattern)Matches anything that does not match any of the patterns provided. May not contain/characters. Similar to*, if alone in a path portion, then the path portion must have at least one character.?(pattern|pattern|pattern)Matches zero or one occurrence of the patterns provided. May not contain/characters.+(pattern|pattern|pattern)Matches one or more occurrences of the patterns provided. May not contain/characters.*(a|b|c)Matches zero or more occurrences of the patterns provided. May not contain/characters.@(pattern|pat*|pat?erN)Matches exactly one of the patterns provided. May not contain/characters.**If a "globstar" is alone in a path portion, then it matches zero or more directories and subdirectories searching for matches. It does not crawl symlinked directories, unless{follow:true}is passed in the options object. A pattern likea/b/**will only matcha/bif it is a directory. Follows 1 symbolic link if not the first item in the pattern, or 0 if it is the first item, unlessfollow:trueis set, in which case it follows all symbolic links.
[:class:] patterns are supported by this implementation, but
[=c=] and [.symbol.] style class patterns are not.
If a file or directory path portion has a . as the first
character, then it will not match any glob pattern unless that
pattern's corresponding path part also has a . as its first
character.
For example, the pattern a/.*/c would match the file at
a/.b/c. However the pattern a/*/c would not, because * does
not start with a dot character.
You can make glob treat dots as normal characters by setting
dot:true in the options.
If you set matchBase:true in the options, and the pattern has
no slashes in it, then it will seek for any file anywhere in the
tree with a matching basename. For example, *.js would match
test/simple/basic.js.
If no matching files are found, then an empty array is returned. This differs from the shell, where the pattern itself is returned. For example:
$ echo a*s*d*f
a*s*d*fWhile strict compliance with the existing standards is a worthwhile goal, some discrepancies exist between node-glob and other implementations, and are intentional.
The double-star character ** is supported by default, unless
the noglobstar flag is set. This is supported in the manner of
bsdglob and bash 5, where ** only has special significance if
it is the only thing in a path part. That is, a/**/b will match
a/x/y/b, but a/**b will not.
Note that symlinked directories are not traversed as part of a
**, though their contents may match against subsequent portions
of the pattern. This prevents infinite loops and duplicates and
the like. You can force glob to traverse symlinks with ** by
setting {follow:true} in the options.
There is no equivalent of the nonull option. A pattern that
does not find any matches simply resolves to nothing. (An empty
array, immediately ended stream, etc.)
If brace expansion is not disabled, then it is performed before
any other interpretation of the glob pattern. Thus, a pattern
like +(a|{b),c)}, which would not be valid in bash or zsh, is
expanded first into the set of +(a|b) and +(a|c), and
those patterns are checked for validity. Since those two are
valid, matching proceeds.
The character class patterns [:class:] (posix standard named
classes) style class patterns are supported and unicode-aware,
but [=c=] (locale-specific character collation weight), and
[.symbol.] (collating symbol), are not.
Unlike Bash and zsh, repeated / are always coalesced into a
single path separator.
Previously, this module let you mark a pattern as a "comment" if
it started with a # character, or a "negated" pattern if it
started with a ! character.
These options were deprecated in version 5, and removed in version 6.
To specify things that should not match, use the ignore option.
Please only use forward-slashes in glob expressions.
Though windows uses either / or \ as its path separator, only
/ characters are used by this glob implementation. You must use
forward-slashes only in glob expressions. Back-slashes will
always be interpreted as escape characters, not path separators.
Results from absolute patterns such as /foo/* are mounted onto
the root setting using path.join. On windows, this will by
default result in /foo/* matching C:\foo\bar.txt.
To automatically coerce all \ characters to / in pattern
strings, thus making it impossible to escape literal glob
characters, you may set the windowsPathsNoEscape option to
true.
On posix systems, when a pattern starts with /, any cwd
option is ignored, and the traversal starts at /, plus any
non-magic path portions specified in the pattern.
On Windows systems, the behavior is similar, but the concept of an "absolute path" is somewhat more involved.
A UNC path may be used as the start of a pattern on Windows
platforms. For example, a pattern like: //?/x:/* will return
all file entries in the root of the x: drive. A pattern like
//ComputerName/Share/* will return all files in the associated
share.
UNC path roots are always compared case insensitively.
A pattern starting with a drive letter, like c:/*, will search
in that drive, regardless of any cwd option provided.
If the pattern starts with /, and is not a UNC path, and there
is an explicit cwd option set with a drive letter, then the
drive letter in the cwd is used as the root of the directory
traversal.
For example, glob('/tmp', { cwd: 'c:/any/thing' }) will return
['c:/tmp'] as the result.
If an explicit cwd option is not provided, and the pattern
starts with /, then the traversal will run on the root of the
drive provided as the cwd option. (That is, it is the result of
path.resolve('/').)
Glob searching, by its very nature, is susceptible to race conditions, since it relies on directory walking.
As a result, it is possible that a file that exists when glob looks for it may have been deleted or modified by the time it returns the result.
By design, this implementation caches all readdir calls that it makes, in order to cut down on system overhead. However, this also makes it even more susceptible to races, especially if the cache object is reused between glob calls.
Users are thus advised not to use a glob result as a guarantee of filesystem state in the face of rapid changes. For the vast majority of operations, this is never a problem.

- If you want glob matching that is as faithful as possible to Bash pattern expansion semantics, and as fast as possible within that constraint, use this module.
- If you are reasonably sure that the patterns you will encounter are relatively simple, and want the absolutely fastest glob matcher out there, use fast-glob.
- If you are reasonably sure that the patterns you will encounter
are relatively simple, and want the convenience of
automatically respecting
.gitignorefiles, use globby.
There are some other glob matcher libraries on npm, but these three are (in my opinion, as of 2023) the best.
full explanation
Every library reflects a set of opinions and priorities in the trade-offs it makes. Other than this library, I can personally recommend both globby and fast-glob, though they differ in their benefits and drawbacks.
Both have very nice APIs and are reasonably fast.
fast-glob is, as far as I am aware, the fastest glob
implementation in JavaScript today. However, there are many
cases where the choices that fast-glob makes in pursuit of
speed mean that its results differ from the results returned by
Bash and other sh-like shells, which may be surprising.
In my testing, fast-glob is around 10-20% faster than this
module when walking over 200k files nested 4 directories
deep1. However, there are some inconsistencies
with Bash matching behavior that this module does not suffer
from:
**only matches files, not directories..path portions are not handled unless they appear at the start of the pattern./!(<pattern>)will not match any files that start with<pattern>, even if they do not match<pattern>. For example,!(9).txtwill not match9999.txt.- Some brace patterns in the middle of a pattern will result in failing to find certain matches.
- Extglob patterns are allowed to contain
/characters.
Globby exhibits all of the same pattern semantics as fast-glob, (as it is a wrapper around fast-glob) and is slightly slower than node-glob (by about 10-20% in the benchmark test set, or in other words, anywhere from 20-50% slower than fast-glob). However, it adds some API conveniences that may be worth the costs.
- Support for
.gitignoreand other ignore files. - Support for negated globs (ie, patterns starting with
!rather than using a separateignoreoption).
The priority of this module is "correctness" in the sense of performing a glob pattern expansion as faithfully as possible to the behavior of Bash and other sh-like shells, with as much speed as possible.
Note that prior versions of node-glob are not on this list.
Former versions of this module are far too slow for any cases
where performance matters at all, and were designed with APIs
that are extremely dated by current JavaScript standards.
[1]: In the cases where this module
