    Defuddle is an open-source JS library I built to parse and extract the main content and metadata from web pages. It can also return the content as Markdown. I built Defuddle while working on Obsidian Web Clipper[1] (also MIT-licensed) because Mozilla's Readability[2] appears to be mostly abandoned, and didn't work well for many sites. It's still very much a work in progress, but I thought I'd share it today, in light of the announcement that Mozilla is shutting down Pocket. This library could be helpful to anyone building a read-it-later app. Defuddle is also available as a CLI:…

    I'm Robbert, the creator of DataGridXL.js. Last month I released version 2 which includes many new features. DataGridXL is a free (and commercial) editable data table library written in ES6. My goal is to develop the most performant & user-friendly spreadsheet-like data table out there: - It has zero dependencies. You don’t need any framework to use DataGridXL. - It is lightweight (~250kb) and easy to use. It does not even require messing with CSS. - It has its own Virtual DOM implementation to prevent DOM errors. - Developer friendly. Supports all modern web browsers Please take a look at…

    An extension of regular expressions for text editing, with a grep-like command-line tool. If you, like me, struggle with group logic in regular expressions, you might find it useful. I wanted to do this for a very long time. It is more of a sketch or prototype. I'd really appreciate your feedback!

    I often need simple text tools (e.g. diffing, epoch time conversion, number base conversion) and was frustrated that I couldn't find a simple option that was as fast as I wanted. Many (SEO-optimized) websites exist, but they unnecessarily send your input to their servers. I used tools like DevToys but their diff has been broken on Mac for a while [1] and it requires installing an app, and CyberChef is good but requires too many interactions (yes, I'm picky). So, I decided to build my own. txtl tries to autodetect what mode you want based on the input, and in general is fast and gets out of…
