    Static Site Boilerplate

    Static Site Boilerplate

    A better workflow for building modern static websites

    A better workflow for building modern static websites. Automated build processes, a local development server, production minification and optimizations, and the latest standards for static websites. Get up and running in seconds with the built-in development server. No need to have a pre-existing server installed on your machine to start developing. Your HTML, styles, and scripts will be automatically linked, concatenated, and minified for optimal loading speed in production. Write your CSS with Sass or Less and without vendor prefixes. Your styles will be automatically processed and prefixed with data based on current browser popularity. All changes to your files while developing are monitored in real-time. Any change to HTML, js, CSS, or images is automatically reloaded in your browser. Images are optimized and compressed for your production build, significantly reducing the overall size of your website files for optimized loading times.

    SuperAgent

    SuperAgent

    Ajax for Node.js and browsers (JS HTTP client)

    SuperAgent is light-weight progressive ajax API crafted for flexibility, readability, and a low learning curve after being frustrated with many of the existing request APIs. It also works with Node.js! Small progressive client-side HTTP request library, and Node.js module with the same API, supporting many high-level HTTP client features. Browser-ready versions of this module are available via jsdelivr, unpkg, and also in the node_modules/superagent/dist folder in downloads of the superagent package. If you are using browserify, webpack, rollup, or another bundler, then you can follow the same usage as Node. SuperAgent is easily extended via plugins. The Node client supports making requests to Unix Domain Sockets. DELETE, HEAD, PATCH, POST, and PUT requests can also be used, simply change the method name. Absolute URLs can be used. In web browsers absolute URLs work only if the server implements CORS.

    Swagger Node

    Swagger Node

    Swagger module for node.js

    The swagger module provides tools for designing and building Swagger-compliant APIs entirely in Node.js. It integrates with popular Node.js servers, including Express, Hapi, Restify, and Sails, as well as any Connect-based middleware. With swagger, you can specify, build, and test your API from the very beginning, on your laptop. It allows you to change and iterate your design without rewriting the logic of your implementation. Remember, one great thing about this approach is that all of the Swagger validation logic is handled for you, and all of the routing logic is managed through the Swagger configuration. You don't have to code (or recode!) any of that stuff yourself.

    TARS

    TARS

    Markup builder on gulp

    TARS is a builder for the modern frontend of any complexity, which is based on Gulp.js. It facilitates and accelerates the process of web development. TARS will be suitable for teams and individual developers. It solves the most routine cases associated with web development and brings you more pleasure from work. TARS is a framework for gulp, including a set of gulp-tasks. It allows for easy expansion (creating new tasks) and customization (modification of existing tasks), provides a comfortable architecture for tasks and watchers storage in the project. To bypass dependency installation for every TARS project, TARS-CLI was created. As such, TARS is not a npm package by itself. This decision was made so that everyone could comfortably customize the builder for themselves. TARS-CLI is just a simple builder interface, which includes all dependencies for TARS. It is strongly recommended to use TARS-CLI for development.

    Twin

    Twin

    Twin blends the magic of Tailwind with the flexibility of css-in-js

    Twin blends the magic of Tailwind with the flexibility of CSS-in-js (emotion, styled-components, stitches, and goober) at build time. When babel runs over your javascript or typescript files at compile time, twin grabs your classes and converts them into CSS objects. These CSS objects are then passed into your chosen CSS-in-js library without the need for an extra client-side bundle. Twin collapses imports from common styling libraries into a single import. Adds no size to your build. Twin converts the classes you’ve used into CSS objects using Babel and then compiles away, leaving no runtime code. Twin chimes in with class and variant values from your Tailwind config. Works with the official tailwind vscode plugin. Avoid having to look up your classes with auto-completion straight from your Tailwind config. Apply variants to multiple classes at once with variant groups.

    UI Bootstrap

    UI Bootstrap

    Bootstrap components written in pure AngularJS by the AngularUI Team

    Bootstrap components written in pure AngularJS by the AngularUI Team. UI Bootstrap provides a set of native AngularJS directives based on Bootstrap's markup and CSS. As a result no dependency on jQuery or Bootstrap's JavaScript is required. Build files for all directives are distributed in several flavours: minified for production usage, un-minified for development, with or without templates. It should be noted that the -tpls files contain the templates bundled in JavaScript, while the regular version does not contain the bundled templates. Alternativelly, if you are only interested in a subset of directives, you can create your own build. Whichever method you choose the good news that the overall size of a download is fairly small: 122K minified for all directives with templates and 98K without (~31kB with gzip compression, with templates, and 28K gzipped without).

    UpUp

    UpUp

    Easily create sites that work offline as well as online

    UpUp is a tiny JavaScript library that makes sure your users can always access your site's content, even when they're on a plane, in an elevator, or 20,000 leagues under the sea. Your users are no longer sitting at their desktops, with a wire connecting them to the internet. They are visiting your site from a phone in an elevator, from their tablet on the subway, or on their laptop while they sit cramped into seat 25 E. This is why modern browsers support service workers, a new technology which lets you serve your content to your users, even when they are offline. UpUp is a free, open-source project which makes using this modern magic as simple as calling one command. While easy to pick up, UpUp is powerful enough to support anything from showing simple messages, to making fully functional single-page applications available offline, with data customized for each of your users.

    Vue Loader

    Vue Loader

    Webpack loader for Vue.js components

    vue-loader is a loader for webpack that allows you to author Vue components in a format called Single-File Components (SFCs). Allows using other webpack loaders for each part of a Vue component. Allows custom blocks in a .vue file that can have custom loader chains applied to them. Treat static assets referenced in <style> and <template> as module dependencies and handle them with webpack loaders. Simulate scoped CSS for each component. State-preserving hot-reloading during development. In a nutshell, the combination of webpack and vue-loader gives you a modern, flexible and extremely powerful front-end workflow for authoring Vue.js applications. vue-loader is not a simple source transform loader. It handles each language blocks inside an SFC with its own dedicated loader chain (you can think of each block as a "virtual module"), and finally assembles the blocks together into the final module.

    Vue Native

    Vue Native

    Vue Native is a framework to build cross platform native mobile apps

    Vue Native is a framework to build cross-platform native mobile apps using JavaScript. It is a wrapper around the APIs of React Native. So, with Vue Native, you can do everything that you can do with React Native. With Vue Native, you get the simplicity of Vue.js. Incrementally build user interfaces with the familiar syntax of HTML and CSS in single file components. Seamless interop with React Native. Use core React Native components with Vue.js syntax out of the box to develop mobile apps on both iOS and Android. The Vue Native CLI can be used to easily generate a fully configured Vue Native app. It wraps expo-cli and react-native-cli to generate a simple single page application (SPA) after installing and configuring dependencies from vue-native-core. You should have either expo-cli or react-native-cli installed as a global dependency.
