Your app includes a user-supplied attribute name in an HTML tag.Your app is being rendered to HTML using ReactDOMServer API, and.Your app might be affected by this vulnerability only if both of these two conditions are true: Note that only the react-dom package needs to be updated. If you’re using a newer version of react-dom, no action is required. If you’re using react-dom/server with one of these versions: If you’re using react-dom/server with this version: Load the common scripts that are used by the KendoReact components including prop-types, kendo-drawing, and kendo-licensing. Follow the steps from the described approach in the official React documentation. We have prepared a patch release with a fix for every affected minor version. You can use KendoReact components in React applications by loading them directly from script files. The tracking number for this vulnerability is CVE-2018-6341. available as scripts from the unpkg CDN (links are included in the following code). We have coordinated this release together with Vue and Preact releases fixing the same issue. Modern Patterns for Developing React Apps Alex Banks, Eve Porcello. While we were investigating this vulnerability, we found similar vulnerabilities in a few other popular front-end libraries. Nevertheless, we recommend to follow the mitigation instructions at the earliest opportunity. Additionally, we expect that most server-rendered apps don’t contain the vulnerable pattern described below. Purely client-rendered apps are not affected. Enzyme is a JavaScript Testing utility for React that makes it easier to test your React Components output. This vulnerability can only affect some server-rendered React apps. It was introduced with the version 16.0.0 and has existed in all subsequent releases until today. Today, we are releasing a fix for a vulnerability we discovered in the react-dom/server implementation. We are releasing a patch version for every affected React minor release so that you can upgrade with no friction. Under the src file, create and copy the following JS code to like_button.jsĬlass LikeButton extends React.We discovered a minor vulnerability that might affect some apps using ReactDOMServer. Under the test folder, create a new src folder Create and copy the following code to the test/index.html file.This method is suitable for project demonstration and learning, not for publishing projects. Store the following code as an html file and open it to see the effect. React does not force the use of JSX, but writing UI with JSX does bring a lot of convenience. It needs a preprocessor to convert JSX into html tags supported by the browser. It writes UI elements in a tag style, which cannot be directly supported by the browser. You can open the html file with a browser to view the effect. The Create React App uses ESLint to test and warn about mistakes in the code. It is a a development server that uses Webpack to compile React, JSX, and ES6, auto-prefix CSS files. Put the above html file and js file in the same folder. Facebook has created a Create React Application with everything you need to build a React app. ReactDOM.render(e(LikeButton), domContainer) Writing React components // like_button.jsĬlass LikeButton extends React.Component ,Ĭonst domContainer = document.querySelector('#like_button_container') Configuring the React environment with HTML Ģ. Only browser native support features are used to load and use React, which is suitable for project demonstration and learning. ReactDOM only contains the function of operating DOM.
