    Aimeos headless distribution

    Aimeos headless distribution

    Aimeos cloud-native, API-first ecommerce headless distribution

    Aimeos Headless is an open-source headless eCommerce distribution built on top of the Laravel framework, designed to provide a fast and scalable API-driven commerce backend. The project exposes a comprehensive REST and GraphQL API that allows developers to build custom storefronts or commerce applications using any frontend technology. Because the platform follows a headless architecture, it separates the commerce logic from the presentation layer, enabling developers to build web, mobile, or progressive web applications while relying on Aimeos for backend functionality. The framework includes a full set of commerce features such as product catalog management, order processing, and customer management while remaining highly customizable. It is designed to scale from small online shops to very large marketplaces and enterprise-level commerce platforms handling massive product catalogs.

    Autoprefixer

    Autoprefixer

    Parse CSS and add vendor prefixes to CSS rules by Can I Use

    PostCSS plugin to parse CSS and add vendor prefixes to CSS rules using values from Can I Use. It is recommended by Google and used in Twitter and Alibaba. Write your CSS rules without vendor prefixes (in fact, forget about them entirely). Autoprefixer will use the data based on current browser popularity and property support to apply prefixes for you. You can try the interactive demo of Autoprefixer. Autoprefixer uses Browserslist, so you can specify the browsers you want to target in your project with queries. It can help you get prefixes for: animations, transition, transform, grid, flex, flexbox and others. You can configure which browsers to generate prefixes for in the distribution. The IE grid layout polyfill is enabled, which is not by default in autoprefixer. Autoprefixer can be used to translate modern CSS Grid syntax into IE 10 and IE 11 syntax, but this polyfill will not work in 100% of cases. This is why it is disabled by default.

    Bootstrap Colorpicker

    Bootstrap Colorpicker

    Bootstrap Colorpicker is a modular color picker plugin for Bootstrap

    Bootstrap Colorpicker is a modular color picker plugin for Bootstrap 4. The Bootstrap JS dependency is optional and it is mainly needed for the popover support. No Bootstrap CSS is required for the plugin to work. To use the plugin without Bootstrap, the popover option should be set to false or null and, depending on your implementation, you will usually need to set inline to true and a container selector option. Note that the plugin may work without Bootstrap if your code is not using any of the mentioned Bootstrap dependencies. Note that the dist files are only distributed via the NPM and Yarn installations. The initial color can be specified in 3 ways, input value, data-color attribute and programmatically with the color constructor option. Whenever the format option is 'auto', the first parsed color format will be detected and used as default, but when the option equals null (default), the format is recalculated every time.

    Browserify

    Browserify

    browser-side require() the node.js way

    Browserify lets you require('modules') in the browser by bundling up all of your dependencies. Browsers don't have the require method defined, but Node.js does. With Browserify you can write code that uses require in the same way that you would use it in Node. Install the uniq module with npm. Now recursively bundle up all the required modules starting at main.js into a single file called bundle.js with the browserify command. Browserify parses the AST for require() calls to traverse the entire dependency graph of your project. Drop a single <script> tag into your html and you're done! browserify is a tool for compiling node-flavored commonjs modules for the browser. You can use browserify to organize your code and use third-party libraries even if you don't use node itself in any other capacity except for bundling and installing packages with npm.

    Critters

    Critters

    A Webpack plugin to inline your critical CSS and lazy-load the rest

    It's a little different from other options because it doesn't use a headless browser to render content. This tradeoff allows Critters to be very fast and lightweight. It also means Critters inlines all CSS rules used by your document, rather than only those needed for above-the-fold content. Critters' design makes it a good fit when inlining critical CSS for prerendered/SSR'd Single Page Applications. It was developed to be an excellent compliment to the prerender-loader, combining to dramatically improve first paint time for most Single Page Applications. Import Critters into your Webpack configuration and add it to your list of plugins. That's it! Now when you run Webpack, the CSS used by your HTML will be inlined and the imports for your full CSS will be converted to load asynchronously. Create a Critters plugin instance with the given options.

    Distpicker

    Distpicker

    Plugin for picking provinces, cities and districts of China

    Distpicker is a lightweight jQuery plugin that provides a cascading dropdown selector for regions such as country, state/province, and city, making it easy to build structured address forms without manual data entry. When initialized on a form, Distpicker automatically populates each related <select> element with hierarchical location data and updates them in response to user selections, ensuring users only see relevant regional options. For example, choosing a country filters the state list, and choosing a state filters the city list, reducing errors and improving the user experience on profile or checkout forms. The plugin is customizable in terms of initial values, placeholder text, and which dropdowns to include, and it also supports dynamic updates if you need to reset or reload region data based on custom logic. It’s especially handy for applications that require structured address input across multiple locales without building and maintaining your own region datasets.

    FlexSlider

    FlexSlider

    An awesome, fully responsive jQuery slider plugin

    Simple, semantic markup. Supported in all major browsers, horizontal/vertical slide and fade animations. Multiple slider support, Callback API, and more. Hardware accelerated touch swipe support. Custom navigation options, compatible with the latest version of jQuery. Display your products in a neatly designed, responsive slideshow within WooCommerce. FlexSlider was built to serve up the best responsive jQuery slider around. I had built a few implementations of responsive sliders on different client projects and noticed that there was a glaring hole for plugin support with the concept. I wanted to build a plugin that would serve the newest of beginners, while providing seasoned developers a tool they could use with confidence. What has come forth is this, FlexSlider. I plan to maintain this plugin and provide support to users implementing FlexSlider into their sites. Responsive web design can be tricky, but I hope that FlexSlider serves to uncomplicate the process, just a little bit.

    IPFS Companion

    IPFS Companion

    Browser extension that simplifies access to IPFS resources on the web

    IPFS Companion allows you to interact with your IPFS node and the extended IPFS network through your browser. The add-on is available for Brave, Chrome, Edge, Firefox, and Opera. It enables support for ipfs addresses, automatically loads websites and file paths from an IPFS gateway, allows you to easily import and share a file with IPFS, and more. IPFS Companion works in tandem with an IPFS node running on your local machine, so make sure you have a node installed before installing this add-on. The easiest way to install IPFS Companion is through your browser's add-on store. Make sure you have IPFS installed (opens new window)on your computer as well. Because IPFS Companion (in its standard configuration) talks to your computer's local IPFS node to work its browser magic, you'll need to have IPFS running on your computer, too.

    No Coin

    No Coin

    No Coin is a tiny browser extension aiming to block coin miners

    No coin is a tiny browser extension aiming to block coin miners such as Coinhive. Even though I think using coin mining in browser to monetize content is a great idea, abusing it is not. Some websites are running it during the entire browsing session which results in high consumption of your computer's resources. I do believe that using it occasionally such as for the proof of work of a captcha is OK. But for an entire browsing session, the user should have the choice to opt-in which is the aim of this extension. The idea was to keep it separate from adblocking. Coin mining in the browser is a different issue. Where ads are tracking you and visually interfering with your browsing experience, coin mining, if abused, is eating your computer resources resulting in slow downs (from high CPU usage) and excessive power consumption. You might be OK with that and not with ads, or vice versa. Or you might just want to keep ads blocked entirely and just enable the coin mining script.
