csv-parser
Streaming csv parser inspired by binary-csv that aims to be faster
csv-parser is a streaming CSV parsing library for Node.js designed for efficiency and correctness. It implements the stream API native to Node, allowing you to pipe a file or readable stream into the parser and process each row (as a JavaScript object or array) as soon as it's parsed — which is crucial for handling large CSV files without loading them entirely into memory. The parser handles standard CSV semantics including quoted fields, variable delimiters, escape sequences, and optional headers; this makes it robust for a variety of CSV dialects you might encounter. Because it works incrementally (row by row), it is well suited for ETL pipelines, data ingestion workflows, CSV-to-database imports, or any context where you need to process or transform large tabular data in Node.js efficiently. Using the .on('data') / .on('end') (or equivalent async patterns), you can accumulate, filter, transform, or stream data further downstream without waiting for the whole file. -

nightTab
A neutral new tab page accented with a chosen colour
A neutral new tab page accented with a chosen color. Customize the layout, style, background and bookmarks with nightTab. Make the browser start page dark (or light, or anything in between). Do not access user information. This means nightTab will not request browser permissions. Aim to make everything on the user interface, within reason, customizable. Aim to make the user experience easy while supporting the above. Keep nightTab open source. Sharing the look and feel of one Bookmark to another can be achieved when editing a single Bookmark. The Bookmark edit modal has three options to copy settings to other Bookmarks. These checkboxes can be found at the bottom of the Visual & Name, Layout and Theme tab. Development and testing is only conducted on Chrome and Firefox. The performance and reliability of nightTab on other browsers is out of the scope of this project. -

Jimp
An image processing library written entirely in JavaScript for Node
An image processing library for Node written entirely in JavaScript, with zero native dependencies. If you're using this library with TypeScript the method of importing slightly differs from JavaScript. Instead of using require, you must import it with ES6 default import scheme. If you're using a web bundles (webpack, rollup, parcel) you can benefit from using the module build of jimp. Using the module build will allow your bundler to understand your code better and exclude things you aren't using. If you're using webpack you can set process.browser to true and your build of jimp will exclude certain parts, making it load faster. The static Jimp.read method takes the path to a file, URL, dimensions, a Jimp instance or a buffer and returns a Promise. In some cases, you need to pass additional parameters with an image's URL. -

Command-line tool to install, manage and run Progressive Web Apps in Firefox. Extension to set up native programs, and install, manage and run PWAs and their profiles directly from the main Firefox browser. Isolated Firefox installation and profile(s) that stores the PWAs.
