Render UPDATED


Why render on The Render Network? Because the future is being built today and hardware limitations should not be what keeps you from being a part of the new digital renaissance. Render puts the power of GPU rendering at your fingertips, at a fraction of the cost and speed of in-house rendering.

The Render Network is designed to connect users looking to perform render jobs with people who have idle GPUs to process the renders. Owners would connect their GPUs to the Render Network in order to receive and complete rendering jobs using OctaneRender. Users would send RNDR to the individual performing the render work and OTOY would receive a small percentage of RNDR for facilitating the transaction and running the Render Network.


Vue recommends using templates to build applications in the vast majority of cases. However, there are situations where we need the full programmatic power of JavaScript. That's where we can use the render function.


h() is short for hyperscript - which means "JavaScript that produces HTML (hypertext markup language)". This name is inherited from conventions shared by many virtual DOM implementations. A more descriptive name could be createVnode(), but a shorter name helps when you have to call this function many times in a render function.


When using templates with Composition API, the return value of the setup() hook is used to expose data to the template. When using render functions, however, we can directly return the render function instead:


If you really want to duplicate the same element/component many times, you can do so with a factory function. For example, the following render function is a perfectly valid way of rendering 20 identical paragraphs:


To create a vnode for a component, the first argument passed to h() should be the component definition. This means when using render functions, it is unnecessary to register components - you can just use the imported components directly:


Passing children to components works a bit differently from passing children to elements. Instead of an array, we need to pass either a slot function, or an object of slot functions. Slot functions can return anything a normal render function can return - which will always be normalized to arrays of vnodes when accessed in the child component.


Functional components are an alternative form of component that don't have any state of their own. They act like pure functions: props in, vnodes out. They are rendered without creating a component instance (i.e. no this), and without the usual component lifecycle hooks.


If you are confident you want to write it by hand, you may compare this.props with nextProps and this.state with nextState and return false to tell React the update can be skipped. Note that returning false does not prevent child components from re-rendering when their state changes.


Currently, if shouldComponentUpdate() returns false, then UNSAFE_componentWillUpdate(), render(), and componentDidUpdate() will not be invoked. In the future React may treat shouldComponentUpdate() as a hint rather than a strict directive, and returning false may still result in a re-rendering of the component.


getDerivedStateFromProps is invoked right before calling the render method, both on the initial mount and on subsequent updates. It should return an object to update the state, or null to update nothing.


Note that this method is fired on every render, regardless of the cause. This is in contrast to UNSAFE_componentWillReceiveProps, which only fires when the parent causes a re-render and not as a result of a local setState.


getSnapshotBeforeUpdate() is invoked right before the most recently rendered output is committed to e.g. the DOM. It enables your component to capture some information from the DOM (e.g. scroll position) before it is potentially changed. Any value returned by this lifecycle method will be passed as a parameter to componentDidUpdate().


Error boundaries are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of the component tree that crashed. Error boundaries catch errors during rendering, in lifecycle methods, and in constructors of the whole tree below them.


In the event of an error, you can render a fallback UI with componentDidCatch() by calling setState, but this will be deprecated in a future release.Use static getDerivedStateFromError() to handle fallback rendering instead.


UNSAFE_componentWillMount() is invoked just before mounting occurs. It is called before render(), therefore calling setState() synchronously in this method will not trigger an extra rendering. Generally, we recommend using the constructor() instead for initializing state.


Note that if a parent component causes your component to re-render, this method will be called even if props have not changed. Make sure to compare the current and next values if you only want to handle changes.


UNSAFE_componentWillUpdate() is invoked just before rendering when new props or state are being received. Use this as an opportunity to perform preparation before an update occurs. This method is not called for the initial render.


setState() enqueues changes to the component state and tells React that this component and its children need to be re-rendered with the updated state. This is the primary method you use to update the user interface in response to event handlers and server responses.


setState() will always lead to a re-render unless shouldComponentUpdate() returns false. If mutable objects are being used and conditional rendering logic cannot be implemented in shouldComponentUpdate(), calling setState() only when the new state differs from the previous state will avoid unnecessary re-renders.


The second parameter to setState() is an optional callback function that will be executed once setState is completed and the component is re-rendered. Generally we recommend using componentDidUpdate() for such logic instead.


Calling forceUpdate() will cause render() to be called on the component, skipping shouldComponentUpdate(). This will trigger the normal lifecycle methods for child components, including the shouldComponentUpdate() method of each child. React will still only update the DOM if the markup changes.


Setup takes under a minute! No complicated code to run or install, and no google collab to muddle through. You will create a free account at DreamStudio (from the makers of Stable Diffusion), and everything will render in the cloud in seconds.


The Opportunities section of your Lighthouse report lists all URLs blocking the first paint of your page. The goal is to reduce the impact of these render-blocking URLs by inlining critical resources, deferring non-critical resources, and removing anything unused.


The first step towards reducing the impact of render-blocking resources is to identify what's critical and what's not. Use the Coverage tab in Chrome DevTools to identify non-critical CSS and JS. When you load or run a page, the tab tells you how much code was used, versus how much was loaded:


Once you've identified critical code, move that code from the render-blocking URL to an inline script tag in your HTML page. When the page loads, it will have what it needs to handle the page's core functionality.


Another approach to eliminating render-blocking styles is to split up those styles into different files, organized by media query. Then add a media attribute to each stylesheet link. When loading a page, the browser only blocks the first paint to retrieve the stylesheets that match the user's device (see Render-Blocking CSS).


By default, React Testing Library will create a div and append that div tothe document.body and this is where your React component will be rendered. Ifyou provide your own HTMLElement container via this option, it will not beappended to the document.body automatically.


By default we'll render with support for concurrent features (i.e.ReactDOMClient.createRoot).However, if you're dealing with a legacy app that requires rendering like inReact 17 (i.e.ReactDOM.render) then youshould enable this option by setting legacyRoot: true.


Pass a React Component as the wrapper option to have it rendered around theinner element. This is most useful for creating reusable custom render functionsfor common data providers. See setup for examples.


? If you find yourself using container to query for rendered elements thenyou should reconsider! The other queries are designed to be more resilient tochanges that will be made to the component you're testing. Avoid usingcontainer to query for elements!


It'd probably be better if you test the component that's doing the prop updatingto ensure that the props are being updated correctly (seethe Guiding Principles section). That said, if you'dprefer to update the props of a rendered component in your test, this functioncan be used to update props of the rendered component.


This will cause the rendered component to be unmounted. This is useful fortesting what happens when your component is removed from the page (like testingthat you don't leave event handlers hanging around causing memory leaks).


This is a convenience wrapper around render with a custom test component. TheAPI emerged from a popular testing pattern and is mostly interesting forlibraries publishing hooks. You should prefer render since a custom testcomponent results in more readable and robust tests since the thing you want totest is not hidden behind an abstraction.


NOTE: When using renderHook in conjunction with the wrapper andinitialProps options, the initialProps are not passed to the wrappercomponent. To provide props to the wrapper component, consider a solutionlike this: 041b061a72
