![]() Then, to save space, you can choose to store all of the configs in the package.json file. Make sure to select the router option with the spacebar just as it is selected above. ? Check the features needed for your project: You’ll see a follow-up questionnaire like this: ? Please pick a preset: Manually select features Open up a terminal in a directory of your choice and create a new project with this command: vue create test_project That said, it’s always advisable to use the Vue CLI because secondary routes are already configured to be lazily loaded by default. We’ll also add a third route manually to show the process for developers that are not familiar with the Vue CLI. To demonstrate lazy loading in Vue.js, we’ll build an example Vue.js app with the Vue CLI and add routing during the configuration stage. ![]() This approach ensures that you have control over the whole experience of the user, which includes the initial wait period when resources are loaded onto the DOM. Lazy loading guarantees that your JavaScript bundle is fed to the DOM in an order of importance from the most-needed component to the least-needed ones. This can become a problem for your end users who might be accessing your application on a mobile device or without fast-speed internet connections. Why is lazy loading important?Īs your Vue.js project grows in size and complexity, the eager loading approach makes the JS bundle very cumbersome. Vue.js combines the async component feature and webpack’s code splitting feature to lazy-load route components. This keeps the bundle size sent down to the DOM from becoming too large. This is done by splitting each route’s components into chunks that are separate from the main chunk loaded on initialization. Vue.js handles loading components lazily with routes, so on the DOM you can load components only when they are needed through routes. Instead, they’re only loaded when requested, which makes the JavaScript bundle size very small at initial load. Lazy loading refers to an approach by which all the scripts are not loaded on the DOM as the application starts. For Vue.js, this means using the import statement to bring in a component into the app.vue file. Eager loading is the default approach to loading JavaScript code on to the DOM. To understand lazy loading, you must first understand eager loading. ![]() Lazy loading means that a target DOM element, relative to a parent DOM element, is loaded and becomes visible (when there is an intersection between both elements, based on a set threshold value) only when a user scrolls through them on a webpage. ![]() Lazy loading is a pattern designed to delay the initialization of elements and objects until they are needed. It consists of an approachable core library that focuses on the view layer only and an ecosystem of supporting libraries designed to help you tackle complexity in large single-page applications. ![]() At the time of writing, Vue.js has more than 183,000 stars on GitHub. Vue.js is a very progressive JavaScript framework created by Evan You and the Vue core team with contributions from over 230 open source community membes. The aim of this demonstration is to help you understand how Vue.js handles lazy loading at the route level of abstraction with the help of webpack code splitting. In this Vue lazy loading tutorial, we’ll demonstrate how to lazily load the components in your Vue.js application.
