Quickstart

const micromatch = require('micromatch');
// micromatch(list, patterns[, options]);

The main export takes a list of strings and one or more glob patterns:

console.log(micromatch(['foo', 'bar', 'baz', 'qux'], ['f*', 'b*'])) //=> ['foo', 'bar', 'baz']
console.log(micromatch(['foo', 'bar', 'baz', 'qux'], ['*', '!b*'])) //=> ['foo', 'qux']

Use .isMatch() to for boolean matching:

console.log(micromatch.isMatch('foo', 'f*')) //=> true
console.log(micromatch.isMatch('foo', ['b*', 'f*'])) //=> true

Switching from minimatch and multimatch is easy!


Why use micromatch?

micromatch is a replacement for minimatch and multimatch

  • Supports all of the same matching features as minimatch and multimatch
  • More complete support for the Bash 4.3 specification than minimatch and multimatch. Micromatch passes all of the spec tests from bash, including some that bash still fails.
  • Fast & Performant - Loads in about 5ms and performs fast matches.
  • Glob matching - Using wildcards (* and ?), globstars (**) for nested directories
  • Advanced globbing - Supports extglobs, braces, and POSIX brackets, and support for escaping special characters with \ or quotes.
  • Accurate - Covers more scenarios than minimatch
  • Well tested - More than 5,000 test assertions
  • Windows support - More reliable windows support than minimatch and multimatch.
  • Safe - Micromatch is not subject to DoS with brace patterns like minimatch and multimatch.

Matching features

  • Support for multiple glob patterns (no need for wrappers like multimatch)
  • Wildcards (**, *.js)
  • Negation ('!a/*.js', '*!(b).js')
  • extglobs (+(x|y), !(a|b))
  • POSIX character classes ([[:alpha:][:digit:]])
  • brace expansion (foo/{1..5}.md, bar/{a,b,c}.js)
  • regex character classes (foo-[1-5].js)
  • regex logical "or" (foo/(abc|xyz).js)

You can mix and match these features to create whatever patterns you need!

Switching to micromatch

(There is one notable difference between micromatch and minimatch in regards to how backslashes are handled. See the notes about backslashes for more information.)

From minimatch

Use micromatch.isMatch() instead of minimatch():

console.log(micromatch.isMatch('foo', 'b*')); //=> false

Use micromatch.match() instead of minimatch.match():

console.log(micromatch.match(['foo', 'bar'], 'b*')); //=> 'bar'

From multimatch

Same signature:

console.log(micromatch(['foo', 'bar', 'baz'], ['f*', '*z'])); //=> ['foo', 'baz']

    Options

    Option Type Default value Description
    basename boolean false If set, then patterns without slashes will be matched against the basename of the path if it contains slashes. For example, a?b would match the path /xyz/123/acb, but not /xyz/acb/123.
    bash boolean false Follow bash matching rules more strictly - disallows backslashes as escape characters, and treats single stars as globstars (**).
    capture boolean undefined Return regex matches in supporting methods.
    contains boolean undefined Allows glob to match any part of the given string(s).
    cwd string process.cwd() Current working directory. Used by picomatch.split()
    debug boolean undefined Debug regular expressions when an error is thrown.
    dot boolean false Match dotfiles. Otherwise dotfiles are ignored unless a . is explicitly defined in the pattern.
    expandRange function undefined Custom function for expanding ranges in brace patterns, such as {a..z}. The function receives the range values as two arguments, and it must return a string to be used in the generated regex. It's recommended that returned strings be wrapped in parentheses. This option is overridden by the expandBrace option.
    failglob boolean false Similar to the failglob behavior in Bash, throws an error when no matches are found. Based on the bash option of the same name.
    fastpaths boolean true To speed up processing, full parsing is skipped for a handful common glob patterns. Disable this behavior by setting this option to false.
    flags boolean undefined Regex flags to use in the generated regex. If defined, the nocase option will be overridden.
    format function undefined Custom function for formatting the returned string. This is useful for removing leading slashes, converting Windows paths to Posix paths, etc.
    ignore array\|string undefined One or more glob patterns for excluding strings that should not be matched from the result.
    keepQuotes boolean false Retain quotes in the generated regex, since quotes may also be used as an alternative to backslashes.
    literalBrackets boolean undefined When true, brackets in the glob pattern will be escaped so that only literal brackets will be matched.
    lookbehinds boolean true Support regex positive and negative lookbehinds. Note that you must be using Node 8.1.10 or higher to enable regex lookbehinds.
    matchBase boolean false Alias for basename
    maxLength boolean 65536 Limit the max length of the input string. An error is thrown if the input string is longer than this value.
    nobrace boolean false Disable brace matching, so that {a,b} and {1..3} would be treated as literal characters.
    nobracket boolean undefined Disable matching with regex brackets.
    nocase boolean false Perform case-insensitive matching. Equivalent to the regex i flag. Note that this option is ignored when the flags option is defined.
    nodupes boolean true Deprecated, use nounique instead. This option will be removed in a future major release. By default duplicates are removed. Disable uniquification by setting this option to false.
    noext boolean false Alias for noextglob
    noextglob boolean false Disable support for matching with extglobs (like +(a\|b))
    noglobstar boolean false Disable support for matching nested directories with globstars (**)
    nonegate boolean false Disable support for negating with leading !
    noquantifiers boolean false Disable support for regex quantifiers (like a{1,2}) and treat them as brace patterns to be expanded.
    onIgnore function undefined Function to be called on ignored items.
    onMatch function undefined Function to be called on matched items.
    onResult function undefined Function to be called on all items, regardless of whether or not they are matched or ignored.
    posix boolean false Support POSIX character classes ("posix brackets").
    posixSlashes boolean undefined Convert all slashes in file paths to forward slashes. This does not convert slashes in the glob pattern itself
    prepend string undefined String to prepend to the generated regex used for matching.
    regex boolean false Use regular expression rules for + (instead of matching literal +), and for stars that follow closing parentheses or brackets (as in )* and ]*).
    strictBrackets boolean undefined Throw an error if brackets, braces, or parens are imbalanced.
    strictSlashes boolean undefined When true, picomatch won't match trailing slashes with single stars.
    unescape boolean undefined Remove preceding backslashes from escaped glob characters before creating the regular expression to perform matches.
    unixify boolean undefined Alias for posixSlashes, for backwards compatitibility.

    Options Examples

    options.basename

    Allow glob patterns without slashes to match a file path based on its basename. Same behavior as minimatch option matchBase.

    Type: Boolean

    Default: false

    Example

    micromatch(['a/b.js', 'a/c.md'], '*.js');
    //=> []
    
    micromatch(['a/b.js', 'a/c.md'], '*.js', { basename: true });
    //=> ['a/b.js']
    

    options.bash

    Enabled by default, this option enforces bash-like behavior with stars immediately following a bracket expression. Bash bracket expressions are similar to regex character classes, but unlike regex, a star following a bracket expression does not repeat the bracketed characters. Instead, the star is treated the same as any other star.

    Type: Boolean

    Default: true

    Example

    const files = ['abc', 'ajz'];
    console.log(micromatch(files, '[a-c]*'));
    //=> ['abc', 'ajz']
    
    console.log(micromatch(files, '[a-c]*', { bash: false }));
    

    options.expandRange

    Type: function

    Default: undefined

    Custom function for expanding ranges in brace patterns. The fill-range library is ideal for this purpose, or you can use custom code to do whatever you need.

    Example

    The following example shows how to create a glob that matches a numeric folder name between 01 and 25, with leading zeros.

    const fill = require('fill-range');
    const regex = micromatch.makeRe('foo/{01..25}/bar', {
      expandRange(a, b) {
        return `(${fill(a, b, { toRegex: true })})`;
      }
    });
    
    console.log(regex)
    //=> /^(?:foo\/((?:0[1-9]|1[0-9]|2[0-5]))\/bar)$/
    
    console.log(regex.test('foo/00/bar')) // false
    console.log(regex.test('foo/01/bar')) // true
    console.log(regex.test('foo/10/bar')) // true
    console.log(regex.test('foo/22/bar')) // true
    console.log(regex.test('foo/25/bar')) // true
    console.log(regex.test('foo/26/bar')) // false
    

    options.format

    Type: function

    Default: undefined

    Custom function for formatting strings before they're matched.

    Example

    // strip leading './' from strings
    const format = str => str.replace(/^\.\//, '');
    const isMatch = picomatch('foo/*.js', { format });
    console.log(isMatch('./foo/bar.js')) //=> true
    

    options.ignore

    String or array of glob patterns to match files to ignore.

    Type: String|Array

    Default: undefined

    const isMatch = micromatch.matcher('*', { ignore: 'f*' });
    console.log(isMatch('foo')) //=> false
    console.log(isMatch('bar')) //=> true
    console.log(isMatch('baz')) //=> true
    

    options.matchBase

    Alias for options.basename.

    options.noextglob

    Disable extglob support, so that extglobs are regarded as literal characters.

    Type: Boolean

    Default: undefined

    Examples

    console.log(micromatch(['a/z', 'a/b', 'a/!(z)'], 'a/!(z)'));
    //=> ['a/b', 'a/!(z)']
    
    console.log(micromatch(['a/z', 'a/b', 'a/!(z)'], 'a/!(z)', { noextglob: true }));
    //=> ['a/!(z)'] (matches only as literal characters)
    

    options.nonegate

    Disallow negation (!) patterns, and treat leading ! as a literal character to match.

    Type: Boolean

    Default: undefined

    options.noglobstar

    Disable matching with globstars (**).

    Type: Boolean

    Default: undefined

    micromatch(['a/b', 'a/b/c', 'a/b/c/d'], 'a/**');
    //=> ['a/b', 'a/b/c', 'a/b/c/d']
    
    micromatch(['a/b', 'a/b/c', 'a/b/c/d'], 'a/**', {noglobstar: true});
    //=> ['a/b']
    

    options.nonull

    Alias for options.nullglob.

    options.nullglob

    If true, when no matches are found the actual (arrayified) glob pattern is returned instead of an empty array. Same behavior as minimatch option nonull.

    Type: Boolean

    Default: undefined

    options.onIgnore

    const onIgnore = ({ glob, regex, input, output }) => {
      console.log({ glob, regex, input, output });
      // { glob: '*', regex: /^(?:(?!\.)(?=.)[^\/]*?\/?)$/, input: 'foo', output: 'foo' }
    };
    
    const isMatch = micromatch.matcher('*', { onIgnore, ignore: 'f*' });
    isMatch('foo');
    isMatch('bar');
    isMatch('baz');
    

    options.onMatch

    const onMatch = ({ glob, regex, input, output }) => {
      console.log({ input, output });
      // { input: 'some\\path', output: 'some/path' }
      // { input: 'some\\path', output: 'some/path' }
      // { input: 'some\\path', output: 'some/path' }
    };
    
    const isMatch = micromatch.matcher('**', { onMatch, posixSlashes: true });
    isMatch('some\\path');
    isMatch('some\\path');
    isMatch('some\\path');
    

    options.onResult

    const onResult = ({ glob, regex, input, output }) => {
      console.log({ glob, regex, input, output });
    };
    
    const isMatch = micromatch('*', { onResult, ignore: 'f*' });
    isMatch('foo');
    isMatch('bar');
    isMatch('baz');
    

    options.posixSlashes

    Convert path separators on returned files to posix/unix-style forward slashes. Aliased as unixify for backwards compatibility.

    Type: Boolean

    Default: true on windows, false everywhere else.

    Example

    console.log(micromatch.match(['a\\b\\c'], 'a/**'));
    //=> ['a/b/c']
    
    console.log(micromatch.match(['a\\b\\c'], { posixSlashes: false }));
    //=> ['a\\b\\c']
    

    options.unescape

    Remove backslashes from escaped glob characters before creating the regular expression to perform matches.

    Type: Boolean

    Default: undefined

    Example

    In this example we want to match a literal *:

    console.log(micromatch.match(['abc', 'a\\*c'], 'a\\*c'));
    //=> ['a\\*c']
    
    console.log(micromatch.match(['abc', 'a\\*c'], 'a\\*c', { unescape: true }));
    //=> ['a*c']
    



    Extended globbing

    Micromatch supports the following extended globbing features.

    Extglobs

    Extended globbing, as described by the bash man page:

    pattern regex equivalent description
    ?(pattern) (pattern)? Matches zero or one occurrence of the given patterns
    *(pattern) (pattern)* Matches zero or more occurrences of the given patterns
    +(pattern) (pattern)+ Matches one or more occurrences of the given patterns
    @(pattern) (pattern) * Matches one of the given patterns
    !(pattern) N/A (equivalent regex is much more complicated) Matches anything except one of the given patterns

    * Note that @ isn't a regex character.

    Braces

    Brace patterns can be used to match specific ranges or sets of characters.

    Example

    The pattern {f,b}*/{1..3}/{b,q}* would match any of following strings:

    foo/1/bar
    foo/2/bar
    foo/3/bar
    baz/1/qux
    baz/2/qux
    baz/3/qux

    Regex character classes

    Given the list: ['a.js', 'b.js', 'c.js', 'd.js', 'E.js']:

    • [ac].js: matches both a and c, returning ['a.js', 'c.js']
    • [b-d].js: matches from b to d, returning ['b.js', 'c.js', 'd.js']
    • a/[A-Z].js: matches and uppercase letter, returning ['a/E.md']

    • (a|c).js: would match either a or c, returning ['a.js', 'c.js']
    • (b|d).js: would match either b or d, returning ['b.js', 'd.js']
    • (b|[A-Z]).js: would match either b or an uppercase letter, returning ['b.js', 'E.js']

    As with regex, parens can be nested, so patterns like ((a|b)|c)/b will work. Although brace expansion might be friendlier to use, depending on preference.

    POSIX bracket expressions

    POSIX brackets are intended to be more user-friendly than regex character classes. This of course is in the eye of the beholder.

    Example

    console.log(micromatch.isMatch('a1', '[[:alpha:][:digit:]]')) //=> true
    console.log(micromatch.isMatch('a1', '[[:alpha:][:alpha:]]')) //=> false
    

    Notes

    Bash 4.3 parity

    Whenever possible matching behavior is based on behavior Bash 4.3, which is mostly consistent with minimatch.

    However, it's suprising how many edge cases and rabbit holes there are with glob matching, and since there is no real glob specification, and micromatch is more accurate than both Bash and minimatch, there are cases where best-guesses were made for behavior. In a few cases where Bash had no answers, we used wildmatch (used by git) as a fallback.

    Backslashes

    There is an important, notable difference between minimatch and micromatch in regards to how backslashes are handled in glob patterns.

    • Micromatch exclusively and explicitly reserves backslashes for escaping characters in a glob pattern, even on windows, which is consistent with bash behavior. More importantly, unescaping globs can result in unsafe regular expressions.
    • Minimatch converts all backslashes to forward slashes, which means you can't use backslashes to escape any characters in your glob patterns.

    We made this decision for micromatch for a couple of reasons:

    • Consistency with bash conventions.
    • Glob patterns are not filepaths. They are a type of regular language that is converted to a JavaScript regular expression. Thus, when forward slashes are defined in a glob pattern, the resulting regular expression will match windows or POSIX path separators just fine.

    A note about joining paths to globs

    Note that when you pass something like path.join('foo', '*') to micromatch, you are creating a filepath and expecting it to still work as a glob pattern. This causes problems on windows, since the path.sep is \\.

    In other words, since \\ is reserved as an escape character in globs, on windows path.join('foo', '*') would result in foo\\*, which tells micromatch to match * as a literal character. This is the same behavior as bash.

    To solve this, you might be inspired to do something like 'foo\\*'.replace(/\\/g, '/'), but this causes another, potentially much more serious, problem.

    Bug reports

    Please create an issue if you encounter a bug or matching behavior that doesn't seem correct. If you find a matching-related issue, please:

    • research existing issues first (open and closed)
    • visit the GNU Bash documentation to see how Bash deals with the pattern
    • visit the minimatch documentation to cross-check expected behavior in node.js
    • if all else fails, since there is no real specification for globs we will probably need to discuss expected behavior and decide how to resolve it. which means any detail you can provide to help with this discussion would be greatly appreciated.

    Platform issues

    It's important to us that micromatch work consistently on all platforms. If you encounter any platform-specific matching or path related issues, please let us know (pull requests are also greatly appreciated).
