    Percollate

    Percollate

    A command-line tool to turn web pages into beautiful, readable PDF

    Percollate is a command-line tool that turns web pages into beautifully formatted PDF, EPUB, or HTML files. By default, percollate processes URLs in parallel. Use the --wait option to process them sequentially instead, with a pause between items. The delay is specified in seconds, and can be zero. By default, percollate bundles all web pages in a single file. Use the --individual flag to export each source to a separate file. Additional CSS styles you can pass from the command line to override styles specified by the default/custom stylesheet. Generate a hyperlinked table of contents. The option is implicitly enabled when bundling more than one web page to a single file. Disable this implicit behavior by passing the --no-to flag. The idea with percollate is to make PDFs that can be printed without losing where the hyperlinks point to. However, for some link-heavy pages, the appended hrefs can become bothersome.

    Pjax module

    Pjax module

    Easily enable fast Ajax navigation on any website

    Pjax is a standalone JavaScript module that uses AJAX (XmlHttpRequest) and pushState() to deliver a fast browsing experience. It allows you to completely transform the user experience of standard websites (server-side generated or static ones) to make users feel like they are browsing an app, especially for those with low bandwidth connections. Pjax does not rely on other libraries, like jQuery or similar. It is written entirely in vanilla JS. Pjax loads pages using AJAX and updates the browser's current URL using pushState() without reloading your page's layout or any resources (JS, CSS), giving a fast page load. It works with all permalinks and can update all the parts of the page you want (including HTML metas, title, and navigation state). It listens to every click on links you want (by default all of them). When an internal link is clicked, Pjax fetches the page's HTML via AJAX.

    Plupload

    Plupload

    JavaScript API for building file uploaders

    At its core Plupload is visually flat and you can customize it however you like. We are using HTML5 APIs. Always. Plupload is based on multi-runtime pollyfills for XMLHttpRequest L2, File and Image APIs. So when there's no HTML5 available in the browser, we emulate it ourselves. Files not only can be picked from browse dialog, but also can be dropped directly from the desktop. In some browsers, mostly in those based on WebKit, it is possible to drag and drop whole folders. Since we emulate as much of HTML5 as possible, we are able (among other things) to provide access to raw file data, even in such environments that do not normally support it. One of the biggest benefits of this is that we can display the thumbnails instantly, right as you select the images in the dialog or drag&drop them from the desktop. We slice the files in chunks and send them out one by one. You can then safely collect them on the server and combine into original file.

    Poi

    Poi

    A zero-config bundler for JavaScript applications

    Poi is a bundler built on the top of webpack, trying to make developing and bundling apps with webpack as easy as possible. Before we get started, ensure that you have installed Node.js (>=8) and Yarn (or npm) on your machine. Inside an empty project, run yarn init or npm init to create a package.json and install Poi. Poi CLI is built into the main package poi. While you can install it globally and run it, it is much better to install it locally into your project as a dev dependency. By default Poi bundles your app in development mode, so running poi alone doesn't really do much but generates an unminified bundle. But you can combine it with --serve flag which starts a dev server to serve the development bundle with hot reloading support. Save it and the browser will automatically reload to apply the changes!

    PouchDB

    PouchDB

    The Database that Syncs!

    PouchDB is an open source, pocket-sized JavaScript database that conveniently synchronizes with servers when it gets back online. It’s inspired by Apache CouchDB, so it’s designed to run well within the browser. PouchDB was created to enable web developers to build applications that will work just as well offline as they do online. It enables applications to store data locally while offline, and once back online it will synchronize with CouchDB and compatible servers, so your data will always be in sync. PouchDB works on various browsers, including Chrome, Firefox, Safari and more. It’s very lightweight and though some programming knowledge is required, is still very easy to learn.

    PowergateIO

    PowergateIO

    A bridge between OrbitDB and Powergate

    A bridge between OrbitDB and Powergate, which is itself a bridge between Filecoin and IPFS. PowergateIO is designed to work with only one configuration option: the gRPC endpoint of the Powergate node you want to connect to. Everything else should be handled "under the hood" for you. PowergateIO is meant to be used from one IPFS node to another, and to replicate OrbitDB databases between them. So, let's assume that we have an IPFS node and OrbitDB running locally, and we're going to interact with a remote Powergate instance. Once you've stored a snapshot and have made note of the DB address returned, you can use that db address to retrieve the snapshot!

    Primus

    Primus

    An abstraction layer for real-time to prevent module lock-in

    Primus, the creator god of transformers but now also known as universal wrapper for real-time frameworks. There are a lot of real-time frameworks available for Node.js and they all have different opinions on how real-time should be done. Primus provides a common low level interface to communicate in real-time using various real-time frameworks. Effortless switching between real-time frameworks by changing one single line of code. No more API rewrites needed when your project requirements change, the framework gets abandoned or simply breaks down. Built-in reconnect, it just works. The reconnect is controlled by a randomised exponential back-off algorithm to reduce server stress. Offline detection, Primus is smart enough to detect when users drop their internet connection (switching WIFI points/cell towers for example) and reconnects when they are back online.

    Public Sans

    Public Sans

    A strong, neutral, principles-driven, open source typeface for text

    A strong, neutral typeface for interfaces, text, and headings. Public Sans is a fork of the SIL Open Licensed face Libre Franklin. Public Sans has many similarities with its parent, but differs enough in its particulars that its effect is distinct. Adjusted vertical metrics. Public Sans is about 2% shorter than Libre Franklin, and has slightly looser default line spacing. Tailed lowercase l. The lowercase l character has a hooked tail for disambiguation. (There is also an optional untailed l.) Regularized stroke weight. Public Sans provides a more regular letterform from the conventional Franklin shape for a cleaner, more consistent letterform, especially at small sizes. Non-rounded vertices. Conventional angled vertices result in a sharper, stronger form. Narrower characters. Public Sans is narrower, especially in rounded characters like lowercase e to help with reading flow, especially in longer texts. Looser letterspacing. Public Sans has relatively loose letterspacing for reading.

    Pure.css

    A set of small, responsive CSS modules that you can use

    A set of small, responsive CSS modules that you can use in every web project. Pure is ridiculously tiny. The entire set of modules clocks in at 3.7KB* minified and gzipped. Crafted with mobile devices in mind, it was important to us to keep our file sizes small, and every line of CSS was carefully considered. If you decide to only use a subset of these modules, you'll save even more bytes. Pure builds on Normalize.css and provides layout and styling for native HTML elements, plus the most common UI components. It's what you need, without the cruft. Pure is responsive out of the box, so elements look great on all screen sizes. Pure has minimal styles and encourages you to write your application styles on top of it. It's designed to get out of your way and makes it easy to override styles. By using Grids, Menus, and more, it's easy to create beautiful responsive layouts for all screen sizes. We've made it easy for you to get started.
