Some examples of such scenarios are:. quickly prototyping an application. As a result, you can include the Vue JS CDN link in your project rather than installing it.

There are two ways to use the Vue with the CDN link. If you want to use Vue for learning purposes or to quickly prototype an application, use the following link:.

When to Use CDN versus Bundling

By including the above link in your application, you are using the latest version of Vue.

If you decide to use Vue from a CDN link in production, you should link to a specific version to avoid issues with newer versions of Vue.

Use Vue by adding the CDN link to your project rather than installing Vue

The link should look as follows:. The version number 3.0.11 can be replaced with any version you want, though. It's important to note that both the above links use the Vue global file - vue.global.js - which is the whole build.

That is, it includes the compiler and the runtime. However, you can use other versions. Check the dist folder to see which versions you can use.

For example, you can use only the runtime file - vue.runtime.global.js - rather than the entire build.

You can do so by using the following link:. These are the two ways you can use Vue without installing it.

Use Vue in production

However, I would recommend installing it through npm or yarn if you want to build a Vue application.

After learning how to use Vue without installing it, you might be interested in reading this article - Learn the fundamentals of Vue JS.

In this article, you are going to learn about how to install Vue by using CDN.

Vue is a lightweight front-end JavaScript framework that is widely used for building Single Page Applications.

To work with Vue, you can install it in many ways, Using CDN(Content Delivery Network) is one of them.

You need to use a script tag to load Vue from a CDN. You can find the CDN script tag for Vue from VueJs official site or unpkg or cdnjs. If you want to work with the latest version of Vue, it is always recommended to use form Vuejs official site.

There are two versions available one is for development and another one is for production. Let’s see the development version script tag first:. This tag is for development purposes. If you are new to Vue and want to learn things in Vue, this version is recommended.

CLI

All you need to do is to copy this tag and link it to your HTML file. If you want to use Vue for production, you need to specify the specific version number so that you will not get an unexpected breakage from the newer version of Vue. See the example below how you link Vue for production:.

For learning purposes, you should always use the un-minified and latest version of Vue so that you can get warnings. Let’s see an example of printing “Hello World from Vue” by using the CDN script tag below:.

Explanation of Different Builds

Here, you can see that in our HTML file we have linked the CDN by using a script tag, and under that script tag, we wrote Vue code with another script tag.

  • You can write it by creating a separate file and then linking it to the HTML file.

  • Finally, to render the value specified in the data object of the Vue instance, we use two curly braces.

  • See the output below:. You can see the output and it comes from Vue. This is how you can install Vue by using CDN.

  • I have an Vue Application built with Webpack and vue template. In my Application I use different components.In one component I want to use a CDN because there is no npm package for this case.I tried to include the CDN via script tag in index.html so my index.html looks like this (popcorn.js is in the same directory as index.html):.

  • in my Component, for example App.vue, i try to use the popcorn CDN like this:. My var definition var popcorn = Popcorn(’#ourvideo’) returns “Popcorn is not defined”.The Object definition for Popcorn is declared in popcorn.js so I think there is something wrong with the CDN include in index.html.Is this the right way to include a cdn in a component?Betonter Text.

  • You can load Vue from a CDN using a script tag.For example, here's how you can load the latest version of Vue 2.x:.

    • Once you load Vue via CDN, Vue will be a global variable that you can use normally.For example, the below is a standalone HTML page that loads Vue 2.x and adds interactivity. Below is a live example. If you include Vue in your JavaScript files using const Vue = require('vue') or import Vue from 'vue', you can still load Vue from a CDN if you define Vue as a Webpack external.

    • There are several advantages to loading Vue via a CDN as opposed to bundling it yourself.For one, the browser can cache Vue separately from your application, which can lead to betterperformance if you update your app frequently but use the same version of Vue.

Runtime + Compiler vs. Runtime-only

For another,your build step will be faster. However, the Vue docs recommend using bundling rather than loading from a CDN for "building large scale applications with Vue". Here's a few reasonswhy you might choose to bundle Vue with Webpack rather than loading via CDN.

The mostimportant reason is single file components: youneed to include Vue in your build step to get SFC support. However, if you don't need SFC support, you can probably get away with using a CDN. Even if youneed to npm install vue for server side rendering or testing in Node, you can use Webpack externals toexclude Vue from your final Webpack bundle in favor of loading via CDN.

Webpack

Rollup

Browserify

Modified4 years, 7 months ago. I chose Vue.js for a new project because it seems to run natively in the browser, as opposed to something like React that has to be compiled/transpiled via Node.

Parcel

Is there any reason I couldn't just link to a CDN like this in my production code?

Development vs. Production Mode

A co-worker suggested that may be for development only, and that unpkg is simply transpiling on the fly (which doesn't sound good for performance).

But other than that it seems to work fine. I could also link to a more robust CDN such as this one, but just want to make sure I'm not violating some sort of best practice by not using a Node build system (e.g.

No, there is no reason not to use a CDN in production. It's even a preferred way for serving content in production mode, especially with common packages like jQuery, because most of the people would already have loaded and therefore cached this resource.

This is absolutely not true - that's why it is a CDN!

Rollup

:) It's a matter of choice, but you have to keep in mind that most of the time you should work with specific version of the library that you are using during development.

Browserify

If you just add the latest version of any code, you are vulnerable to all changes pushed to that repository, and so your clients will start receiving updated code, which you haven't tested yet.

Therefore fix to a specific version that you develop with, open a beer and have a good sleep :).

These maybe help:.

Dev Build

And it will keep current version of Vue.js automatically.

Bower

Only UMD builds are available from Bower.

AMD Module Loaders

All UMD builds can be used directly as an AMD module.
