    Primitive UI

    Primitive UI

    A front-end design toolkit for developing web apps

    Primitive is a minimalist Sass boilerplate that provides helpful, browser-consistent styling for default HTML elements - buttons, forms, tables, lists, and typography. A front-end design toolkit built with Sass for developing responsive web apps. Primitive also provides helpful, browser-consistent styling for default HTML elements - buttons, forms, tables, lists, and typography. There are three container sizes for content that are centered with left and right padding. Content without a container will span the width of the viewport. The font size is set to 1rem on the HTML element, so all font sizing will cascade from the root. Headings all have the same line height and margins, and only the font size is individually defined. The blockquote is set to have a left border, with the browser default padding removed. A citation will be right-aligned and italicized.

    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.

    Protractor

    Protractor

    E2E test framework for Angular apps

    Protractor is an end-to-end test framework for Angular and AngularJS applications. Protractor runs tests against your application running in a real browser, interacting with it as a user would. Protractor is built on top of WebDriverJS, which uses native events and browser-specific drivers to interact with your application as a user would. Protractor supports Angular-specific locator strategies, which allows you to test Angular-specific elements without any setup effort on your part. You no longer need to add waits and sleeps to your test. Protractor can automatically execute the next step in your test the moment the webpage finishes pending tasks, so you don’t have to worry about waiting for your test and webpage to sync. Protractor needs two files to run, a spec file and a configuration file. Open a new command line or terminal window and create a clean folder for testing.
