When history is not added, clicking link back and forth will report the following error in the console:Warning: Hash history cannot push the same path; a new entry will not be added to the history stackThe solution is to install and use the history module.Import createbrowserhistory from "History/createbrowserhistory"; const customhistory = createbrowserhistory (); Note that the introduced hashrouter is changed to a router.How does a REACT project use

Original address: Http://www.csdn.net/article/2015-08-04/2825370-reactIn the 2004, it was a milestone year for the front-end community. Gmail turned out to be a native app-level experience based on front-end rendering that boosted the time and touched the user's G-spot relative to the previous service-side rendering of the Web page. Since then, the front-end rendering site has been the direction that countless developers are chasing.To better develop front-end rendering of "native-level" sites,

What Is InfernoInferno can be seen as another streamlined, high-performance implementation of react. It is used in the same way as react, whether it is JSX syntax, component building, component life cycle, or with Redux or MOBX, routing control, etc., can be basically in accordance with the react way to develop, only a small difference. However, Inferno is design
The purpose and meaning of the react Web is very clear: let react native code run on the web so that a set of code runs at each mobile terminal, for the front-end and the business, this is a qualitative improvement in development efficiency. At the beginning of the project, we consulted the react team about similar issues, and the core students of their team @vje
React originally came from a Facebook-based advertising system project, where front-end development was a huge challenge in the implementation of the project, and the code became bloated and messy and difficult to maintain. So, they decided to throw away many so-called "best practices" and rethink the way the front-end interface was built, so there was react.React brings a lot of pioneering ideas to build the front-end interface, although one of the m
The previous article mainly introduced the basic usage of react, this time will introduce a react routing component-react-router.In Web application development, the routing system is an integral part. When the browser's current URL changes, the routing system responds with a response that ensures that the user interface is synchronized to the URL. With the advent

Keys are secondary identifiers used by react to track which elements in the list are modified, added, or removed.

In the development process, we need to ensure that the key of an element is unique among its same-level elements. In the
The choice of Angular 2 and react is really just a style preference. React is focused on rendering speed and can handle complex UI designs in client or native applications, while angular 2 is more development-wide. It can not only guide us to build our own applications, but also provide some expressive and reusable UI design mechanism.Reactjs Quick Review

The most magical part of react is the virtual DOM, and its efficient diff algorithm. This allows us to "refresh" the entire page at any time without worrying about performance issues and "without scruple", by the virtual DOM to ensure that the actual DOM operation is performed only on the truly changing parts of the interface. React is transparent enough in this section, and in real-world development we don
