glob-stream

What is glob-stream?

The glob-stream npm package allows for reading file paths from a globbing pattern. It is a wrapper around node-glob and vinyl-fs to stream the file objects that match the glob patterns. This package is particularly useful in build processes and file manipulation scripts where matching files based on patterns is required.

What are glob-stream's main functionalities?

Reading files using glob patterns

This feature allows you to read files that match a specific pattern. In the code sample, all JavaScript files under the 'src' directory and its subdirectories are matched and their paths are logged.

const globStream = require('glob-stream');

const stream = globStream('./src/**/*.js');
stream.on('data', function(file) {
  console.log(file.path);
});

Combining multiple glob patterns

glob-stream supports combining multiple patterns, including exclusion patterns. In this example, all JavaScript files under 'src' except those in the 'vendor' subdirectory are matched.

const globStream = require('glob-stream');

const stream = globStream(['./src/**/*.js', '!./src/vendor/**']);
stream.on('data', function(file) {
  console.log(file.path);
});

Other packages similar to glob-stream

fast-glob

fast-glob is an alternative to glob-stream that provides a similar functionality of matching files based on glob patterns. It is known for its performance and offers a promise-based API, making it a good choice for modern asynchronous workflows. Unlike glob-stream, fast-glob does not return a stream of file objects but rather a promise that resolves with an array of matching paths.

node-glob

node-glob is the underlying library used by glob-stream for matching files based on patterns. While glob-stream provides a stream interface for handling the matched files, node-glob itself focuses on the globbing functionality and returns an array of matched file paths. It is a more basic option for those who do not need the streaming capabilities offered by glob-stream.

glob-stream

Information

Package	glob-stream
Description	File system globs as a stream
Node Version	>= 0.9

This is a simple wrapper around node-glob to make it streamy.

Usage

var gs = require('glob-stream');

var stream = gs.create("./files/**/*.coffee", {options});

stream.on('data', function(file){
  // file has path, base, and cwd attrs
});

You can pass any combination of globs. One caveat is that you can not only pass a glob negation, you must give it at least one positive glob so it knows where to start. All given must match for the file to be returned.

Options

• cwd
  • Default is process.cwd()
• base
  • Default is everything before a glob starts (see glob2base)
• cwdbase
  • Default is false
  • When true it is the same as saying opt.base = opt.cwd

This argument is passed directly to node-glob so check there for more options

Glob

var stream = gs.create(["./**/*.js", "!./node_modules/**/*.*"]);
