Build Truly Native Mobile Apps with Vue | NativeScript NativeScript and Vue.js The lightweight nature of Vue.js makes it perfect for mobile development. In addition, if you are already a Vue developer, much of the Vue syntax and app architecture will seem very familiar. All you need to do in a NativeScript-Vue app is switch the plugin you include at the start, change your app instantiation parameters, and write your front-end templates to use NativeScript modules, rather than web markup. Here are the three main differences between Vue.js for the web, and NativeScript-Vue: 1. 2. 3. Getting Started There are a couple of ways to start using NativeScript-Vue: When you get to the point where you are ready to put your app out there, you need to jump on the more advanced wagon and install NativeScript tools locally and then pick a template to start with. Use these resources to continue your journey: Documentation The documentation will help you learn the ins and outs of making truly native mobile applications with Vue.js and NativeScript.

Vue CLI 3 Le nouvel utilitaire de développement pour Vue.js vient de sortir sa troisième version. À l'instar d'Angular CLI pour Angular et Spring Initializr pour Spring Boot, Vue CLI (pour Command Line Interface) permet de générer des applications Vue.js. Ce client a été entièrement réécrit par rapport à sa version précédente. À travers cet article, je vais vous présenter quelques unes de ses fonctionnalités, pour en savoir davantage, l'excellente documentation de Vue CLI sera votre meilleure alliée. Le client s'installe comme une commande système avec votre gestionnaire de dépendances Node.js préféré : npm :npm install -g @vue/cli Yarn :yarn global add @vue/cli Il suffit de lancer la commande vue pour avoir le résultat suivant : Créer Ensuite, la commande vue create, avec en argument un nom, permet de créer un projet Vue.js. La console va maintenant devenir interactive, voici les 9 étapes de vue create sur une base TypeScript et des tests Jest : ? ? ? ? ? ? ? ? ? ? Analyser Les Tâches Derrière tout ça
Thinking in React | React Edit on GitHub React is, in our opinion, the premier way to build big, fast Web apps with JavaScript. It has scaled very well for us at Facebook and Instagram. One of the many great parts of React is how it makes you think about apps as you build them. In this document, we'll walk you through the thought process of building a searchable product data table using React. Start With A Mock # Imagine that we already have a JSON API and a mock from our designer. Our JSON API returns some data that looks like this: Step 1: Break The UI Into A Component Hierarchy # The first thing you'll want to do is to draw boxes around every component (and subcomponent) in the mock and give them all names. But how do you know what should be its own component? Since you're often displaying a JSON data model to a user, you'll find that if your model was built correctly, your UI (and therefore your component structure) will map nicely. You'll see here that we have five components in our simple app. And That's It #
Overview | Vue CLI 3 This documentation is for @vue/cli version 3.x. For the old vue-cli, see here. Vue CLI is a full system for rapid Vue.js development, providing: Interactive project scaffolding via @vue/cli. Zero config rapid prototyping via @vue/cli + @vue/cli-service-global. Vue CLI aims to be the standard tooling baseline for the Vue ecosystem. There are several moving parts of Vue CLI - if you look at the source code, you will find that it is a monorepo containing a number of separately published packages. The CLI (@vue/cli) is a globally installed npm package and provides the vue command in your terminal. CLI Service The CLI Service (@vue/cli-service) is a development dependency. The CLI Service is built on top of webpack and webpack-dev-server. The core service that loads other CLI Plugins; An internal webpack config that is optimized for most apps; The vue-cli-service binary inside the project, which comes with the basic serve, build and inspect commands.

Lucy | How does React decide to re-render a component? React is known for it’s performance. Because it has a virtual DOM and only updates the real DOM when required it can be much faster than updating the DOM all the time, even to display the same information. However, React’s “smarts” only go so far (at the moment!), and it’s our job to know it’s expectations and limitations so we don’t accidentally hurt performance. One of the aspects we need to be aware of is how React decides when to re-render a component. 1. A re-render can only be triggered if a component’s state has changed. Component changed? In this (massively contrived) example the Todo will re-render every second, even though the render method doesn’t use unseen at all. Well, but re-rendering all the time isn’t helpful... I mean, I appreciate that React is being super careful. But re-rendering seems expensive (and your example is melodramatic) Yes, re-rendering unnecessarily does waste cycles and is generally not a good idea. How can we tell React to skip re-rendering? It can be.
