This might be good enough for very simple applications. In the main index.html file, we have declared a couple of preload Resource Hints to prevent waterfall-loading of JavaScript resources. Register for the Newsletter of my upcoming book: Advanced Vue.js Application Architecture. The preload links tell the browser to load all necessary files, which prevents waterfall-loading.ĭo you want to learn more about advanced Vue.js techniques? But we can speed this up by using modulepreload links. So the browser needs to load the files in this order before it can mount our little Vue application. In our example, main.js imports App.js and App.js imports BaseButton.js. One problem with using JavaScript Modules without a bundler is waterfall-loading. The second JavaScript file is the entry point of our application – note the type="module" attribute on the script tag this tells the browser that this is a JavaScript file using ES6 Modules. With the first tag, we’re loading a version of Vue.js with some development console outputs enabled (do not use this in production!). The most important part of the application is the JavaScript code. Unfortunately, that means we have to install an npm dependency – but that’ll be the only one, I promise.Ībove, you can see the very minimal HTML code needed for our application. To enhance security, ES6 Modules are subject to same-origin policy, which means we have to run a local server to run JavaScript applications using this technology. Setting up a Development Environment with Automatic Reloading But thanks to htm, we can get pretty close to the Vue SFC experience. vue Single File Component files, it is not that simple in the Vue.js ecosystem.įirst things first, there is no way to make. Thanks to modern browsers and mostly thanks to features like JavaScript Modules, bundling via a separate build step is not strictly necessary even when building medium-sized web apps. Building Vue Applications Without a Build Stepīuilding Vue Applications Without a Build Step.You can find the final code using htm for rendering on GitHub. At the same time, we don’t want to do without powerful functionality like code splitting, and the development process should be as comfortable as possible. This article discusses ways to build Vue.js applications without relying on a complicated build process and numerous third-party dependencies. Thanks to native browser support for JavaScript Modules, it’s easier than ever to build powerful JavaScript applications without using any build tools. Nowadays, building web applications requires complex build toolchains, a node_modules directory with gigabytes of dependencies, and a complicated webpack configuration file.īut is it really necessary to use webpack to build modern JavaScript applications? Is it really necessary to use webpack to build Vue.js-powered applications? The answer is no. ![]() html file, add a tag, write some JavaScript, and open the file in the browser. ![]() In the good old times, creating a JavaScript-enhanced website was straightforward: create a.
