globby

What is globby?

The globby npm package is a JavaScript library that provides a convenient interface for file system pattern matching using glob patterns. It is built on top of node-glob and fast-glob, offering a powerful and flexible way to match file paths against specified patterns. It supports multiple patterns, negated patterns, and can handle file system operations asynchronously or synchronously.

What are globby's main functionalities?

Asynchronous file pattern matching

This feature allows you to match files using glob patterns asynchronously. The example code shows how to match all files in a directory and its subdirectories, excluding the 'node_modules' directory.

const globby = require('globby');
globby(['**/*', '!node_modules']).then(paths => {
  console.log(paths);
});

Synchronous file pattern matching

This feature allows you to match files using glob patterns synchronously. The example code demonstrates how to perform the same operation as the asynchronous example, but in a synchronous manner.

const globby = require('globby');
const paths = globby.sync(['**/*', '!node_modules']);
console.log(paths);

Expand directories

This feature automatically expands directory patterns to match files with specified extensions. The example code matches all JavaScript and TypeScript files within the 'src' directory.

const globby = require('globby');
globby(['src/**'], { expandDirectories: ['js', 'ts'] }).then(paths => {
  console.log(paths);
});

Stream interface

This feature provides a stream interface for handling large sets of matched files. The example code creates a stream that emits paths for all files in a directory and its subdirectories.

const globby = require('globby');
const stream = globby.stream('**/*');
stream.on('data', path => {
  console.log(path);
});

Other packages similar to globby

fast-glob

fast-glob is a fast and efficient library for pattern matching. It is one of the underlying libraries used by globby. Compared to globby, fast-glob provides lower-level control but lacks some convenience features like negated patterns and directory expansion.

node-glob

node-glob is the original glob implementation for Node.js. It is also used by globby under the hood. While it is feature-rich, globby provides a more modern and simpler API, as well as additional features like promise support and multiple pattern matching.

micromatch

micromatch is a minimal matching utility that provides glob matching functionality. It is designed to be faster and more efficient than node-glob. However, globby offers a more user-friendly API and additional features like asynchronous matching and directory expansion.

patterns

callback(err, paths)

Globbing patterns

Just a quick overview.

• * matches any number of characters, but not /
• ? matches a single character, but not /
• ** matches any number of characters, including /, as long as it's the only thing in a path part
• {} allows for a comma-separated list of "or" expressions
• ! at the beginning of a pattern will negate the match

Various patterns and expected matches.
