Below is a little demo using Vue.compile to live-compile a template string: Deployed on When Vue is updating a list of elements rendered with v-for, by default it uses an “in-place patch” strategy.
Feel free to skip it and come back later.
You get paid, we donate to tech non-profits. You’re browsing the documentation for v2.x and ealier.
You may be interested to know that Vue's templates actually compile to render functions.
Refer to style guide for details.
For example: example1.items.push({ message: 'Baz' }). Vue wraps an observed array’s mutation methods so they will also trigger view updates. This means that our new my-component will go through all of its lifecycles as normal — created, mounted, and so on. Write for DigitalOcean
However, this won’t automatically pass any data to the component, because components have isolated scopes of their own. "Virtual DOM" is what we call the entire tree of VNodes, built by a tree of Vue components.
// An object corresponding to the attributes, props and events, // or using strings to get 'text VNodes' or, /** Recursively get text from children nodes */, // create kebab-case id from the text contents of the children, // Abort if the element emitting the event is not, // Abort if the key that went up is not the enter, // key (13) and the shift key was not held down, // Prevent the default keyup handler for this element, // `
`, // `
{{ props.text }}
`, // in the form of { name: props => VNode | Array

This component primarily does two things. Last updated: 9/25/2020, 3:44:34 AM. We call this node description a "virtual node", usually abbreviated to VNode.
It does the same thing as , but works around a potential browser parsing error.
For example: Note that it’s not recommended to use v-if and v-for together.
We’ll be using pixi.js for this guide, so be sure to install that via npm. Unfortunately, there’s still a DOM representation present for any container components due to Vue requiring you to have an element to render if you want to add children to your component. While Vue doesn’t explicitly support this at the moment, it’s entirely possible to implement yourself, as you’ll discover below.
Use string or numeric values instead. You get paid; we donate to tech nonprofits. In this case it will repeat the template that many times. It's on our list, and we're working on it! When they exist on the same node, v-for has a higher priority than v-if.
These are discussed in the reactivity section.
