ironsource/node-ella

the complete solution for node.js command-line programs

writable stream that concatenates strings or binary data and calls a callback with the result

Cross platform child_process#spawn and child_process#spawnSync

Collision-resistant ids optimized for horizontal scaling and performance. For node and browsers.

Transform stream that gunzips its input if it is gzipped and just echoes it if not

A stream that emits multiple other streams one after another (streams3)

Run a function exactly one time

pipe streams together and close all of them if one of them closes

hardwired configuration loader

Simplified HTTP request client.

A deep deletion module for node (like `rm -rf`)

The semantic version parser used by npm.

filesystem bindings for tar-stream

tar-stream is a streaming tar parser and generator and nothing else. It operates purely using streams which means you can easily extract/parse tarballs without ever hitting the file system.

A tiny wrapper around Node.js streams.Transform (Streams2/3) to avoid explicit subclassing noise

Write files in an atomic fashion w/configurable ownership

extend like a boss

after - tiny flow control

No-bullshit, ultra-simple, 35-lines-of-code async parallel forEach / map function for JavaScript.

Apply an async function to each Array element in series.

fstream class for creating npm packages

deterministic JSON.stringify() with custom sorting to get deterministic hashes from stringified results

Like npm-package-arg, but more so, producing full file paths and differentiating local tar and directory sources.

Run an array of functions in series

Compare two semver version or version range strings.

Keep writing to the same line in the terminal. Very useful when you write progress bars, or a status message during longer operations
