The final output of vue-loader is a JavaScript module ready for inclusion in your Webpack bundle. the script block goes to babel-loader, while the template block goes to Vue's own vue-template-loader which transforms the template into a JavaScript render function. This loader splits up the SFCs language blocks and pipes each to an appropriate loader, e.g. SFCs are made possible by the vue-loader Webpack plugin. Vue has an elegant solution called Single File Components (SFCs) that include the template, component definition and CSS all in one neat. These come with an intrinsic problem, though: either your HTML markup needs to be in an awkward JavaScript string, or your template and component definition will need to be in separate files, making them hard to work with. One of Vue's idiosyncratic features is the use of HTML for component templates. They're well optimised and there are no improvements I can suggest!īut since they work so well out of the box, you probably don't have much idea of what they're really doing, right? Consider this article an overview of the Webpack config used in the vue-cli templates, as they include the same optimisations I'm discussing here. If you're using a template to build your app from vue-cli, a pre-made Webpack config is provided. These mutation methods are: push () pop () shift () unshift () splice () sort () reverse () Replacing an Array Mutation methods, as the name suggests, mutate the original array they are called on. In this article I'll explain four ways that Webpack can enhance your Vue app, including: Vue is able to detect when a reactive array's mutation methods are called and trigger necessary updates. It makes your development workflow much simpler by managing complex build steps and can optimise your apps size and performance. Īnd as you can see, we now have access to both the range of numbers and the loop index, and we can do with those whatever we please.Webpack is an essential tool for developing Vue.js single page applications. This syntax also enables you to access the loop index in exactly the same way as you have previously seen. And sure enough, we see a list containing the numbers from one to ten. What Vue.js does for us, is that it loops ten times and increments n by one for each iteration. So if I wanted to output a list of the numbers from one to ten, I would give the current number an alias followed by the in keyword and the number ten. By specifying a number as the expression, the template will be repeated that number of times. In this short lecture, I am going to show you how you can output a range of numbers with the v-for directive.
