# Glob 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.)  ## Usage 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`. ```js // 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. ## Command Line Interface ``` $ 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:
