    parrot-mocker-web

    parrot-mocker-web

    Simple web server to forward received requests to real servers

    This project provides a simple mock server, which works with the Chrome plugin parrot-mocker. Install the Chrome plugin, parrot-mocker, so that your pages have the ability to intercept requests and forward to this mock server. Other usages without the plugin can refer to the parrot-mocker project. For example, if deployed in leancloud, please open your Chrome browser and visit the index page first. Other instances like now.sh are similar. Now you will find that requests are forwarded to the mock server, which are also visiable at index page. If visiting other pages in the same domain, their requests will also be forwarded to this mock server.

    reactstrap

    reactstrap

    Simple React Bootstrap 5 components

    Reactstrap is currently compatible with Bootstrap 5.1. If you are using Bootstrap 4, you'll need to use Reactstrap v8. This library contains React Bootstrap components that favor composition and control. The library does not depend on jQuery or Bootstrap javascript. However, Poppers.js via react-popper is relied upon for advanced positioning of content like Tooltips, Popovers, and auto-flipping Dropdowns. There are a few core concepts to understand in order to make the most out of this library. Your content is expected to be composed via props.children rather than using named props to pass in Components. Attributes in this library are used to pass in-state, conveniently apply modifier classes, enable advanced functionality (like tether), or automatically include non-content-based elements.
