#Vuejs keyup update
They technically shouldn’t be, because nothing in them is changing right ? No props update or no data update etc. Whats happening here is every single time the div grows in length (a simple progress bar) all the buttons will be re-rendered as well. Whenever an anonymous function is passed to the “onClick” of a button, Ive seen this pattern amongst devs who come from React because that’s one of the ways in React to pass custom data to a function, its better to not pass an anonymous function. Unless the child depends on the parent wrt to data, it should operate fine. Often times, we might create a component that has a wrapper which re-renders a lot and the some other part of the same template has to do ALOT of work whenever the other part of the template re-renders, an easy fix is to simply componentise the file. The goal of the vDOM is to act as an intermediary update medium and track (very efficiently) isolated changes to the UI of the project and triggered isolated rerenders to those targeted components vs actually repainting the entire screen. This one would be a little more obvious to most, given how Vue’s vDOM system operates. Inorder for us to maintain state and prevent re-loading of data whenever components are toggled, DOMless wrapper acts as a good solution to speed things up Sometimes we load components on the fly using is prop provided by Vue, and we might switch between components that are dynamically loaded. Using keep-alive for dynamically loaded components.

QUICK EDIT: Because it’s a functional component, the context of this is non-existent, so to access props, you need to do props.name - Thanks to Dinesh Madhanlal for the mention If you read into it, you see props being passed called functional: trueĪs simple as that, you don’t need to worry about changing your template syntax, you can stick to it and still enjoy the luxury of Vue syntax. This can be easily created into a Vue based functional component with the use of the render method What we have here is a “functional” template, in that it has no declared state, and only deals with props. Let’s jump straight into it - talk about some simple ways you can increase the performance of your VueJS application.
#Vuejs keyup code
See usually small start up projects and codebases, the goal is to push code out and get the product out to the customer fast, which we’re great at - you can check out our work at but beyond that as engineers our goal is to take care of performance and scalability. Code that serves millions of people so my job is not just to build scalable code patterns but actually care ALOT about performance. I’ve been involved in VueJS for a good 2 years (since 1.0 came out) and basically helped build/train 3 of the largest VueJS codebases in Sydney.
