bun-glob

Bun includes a fast native implementation of file globbing.

Quickstart

Scan a directory for files matching *.ts:

import { Glob } from "bun";

const glob = new Glob("**/*.ts");

// Scans the current working directory and each of its sub-directories recursively
for await (const file of glob.scan(".")) {
  console.log(file); // => "index.ts"
}

Match a string against a glob pattern:

import { Glob } from "bun";

const glob = new Glob("*.ts");

glob.match("index.ts"); // => true
glob.match("index.js"); // => false

Glob is a class which implements the following interface:

class Glob {
  scan(root: string | ScanOptions): AsyncIterable<string>;
  scanSync(root: string | ScanOptions): Iterable<string>;

  match(path: string): boolean;
}

interface ScanOptions {
  /**
   * The root directory to start matching from. Defaults to `process.cwd()`
   */
  cwd?: string;

  /**
   * Allow patterns to match entries that begin with a period (`.`).
   *
   * @default false
   */
  dot?: boolean;

  /**
   * Return the absolute path for entries.
   *
   * @default false
   */
  absolute?: boolean;

  /**
   * Indicates whether to traverse descendants of symbolic link directories.
   *
   * @default false
   */
  followSymlinks?: boolean;

  /**
   * Throw an error when symbolic link is broken
   *
   * @default false
   */
  throwErrorOnBrokenSymlink?: boolean;

  /**
   * Return only files.
   *
   * @default true
   */
  onlyFiles?: boolean;
}

Supported Glob Patterns

Bun supports the following glob patterns:

? - Match any single character

const glob = new Glob("???.ts");
glob.match("foo.ts"); // => true
glob.match("foobar.ts"); // => false

* - Matches zero or more characters, except for path separators (/ or \)

const glob = new Glob("*.ts");
glob.match("index.ts"); // => true
glob.match("src/index.ts"); // => false

** - Match any number of characters including /

const glob = new Glob("**/*.ts");
glob.match("index.ts"); // => true
glob.match("src/index.ts"); // => true
glob.match("src/index.js"); // => false
