For example this can be used to set the aria-hidden attribute: ARIA and data attributesĬollapse transfers aria- and data- attributes to the component's rendered DOM element. Here is an llapse-css-transition : PropTypes.funcĬallback function for when the component has mounted. :warning: ️You need to specify the transition property or add a class selector with style (transition) in your own stylesheet to add animation. Let’s end with a cool Trivia by Dan Abramov on twitter.Collapse component with CSS transition for elements with variable and dynamic height.Ĭomponent-wrapper for collapse animation with CSS for elements with variable and dynamic height. In the end, we cannot deny that the team at react care more about helping developers create apps with the barest minimum constraint than they care about their API being pristinely clean and that is one of the major reasons why we ❤️react. That being said, the team at React is not hoarding features and it is very important to remember that React has barely changed in the last 5 years. They have come out to say that this is a very intentional move because they care so much about Backward Compatibility. Well, the dedicated react team are in all honesty adding more than they remove from react at every new version. How complex the core react API has become over time.The new Suspense encourages global state and removes the possibility to safely store costly state like REST resources anywhere in the tree causing cache invalidation.So there is a few observations and early reactions from developers to the new version with some conversations over things like: Hooks can also be used as Bit components. Here is a link to the official documentation. it is however designed to do so in a future release this release is to make us get acquainted with it first. As of this writing, getDerivedStateFromError() is not yet available for server side rendering. Suspense is not yet available for server side rendering, support for suspense would ship with a later release.Strict mode was introduced in React version 13. There is absolutely no need to panic if you do not use strict mode. Hopefully the addition of the contextType API makes this a bit easier. The team at react strongly encourages upgrading to the new context API. Legacy Context: using contextTypes and getChildContext - Legacy context makes React slightly slower and bigger than it needs to be.ReactDOM.findDOMNode(): This API was deprecated in this version because it is really slow when tested in React 16.6 also it is often times misunderstood and most of the features are not necessary.The following APIs have been deprecated in STRICT MODE from React 16.6 Secondly, it does not work to recover from server side errors since the Did lifecycle methods do not get triggered during the server side rendering. It has been observed that sometimes, this breaks parents components whose refs should not be empty. The little problem is that when before setState is called, react renders null in place of the particular tree that threw the error. Another thing componentDidCatch lifecycle method helps to do is to display a different user interface to the user by calling setState. This lifecycle method gets called only after an error has occurred this in turn helps in server side error logging. If you are familiar with error handling in React, you would remember the componentDidCatch lifecycle method. Error boundaries, according to the react docs basically catches javascript errors anywhere in their child component tree, log the errors and display a kind of fallback user interface instead of the crashed component. React 16 introduced Error Boundaries to solve the problem of a javascript error in a particular component breaking the whole app.
