Components in a static site too

In the 2nd part of this series, we learned about some basics of rendering a view. We ended that topic by having a look at the router. The router just had one path, the root (/), which was mapped to a single component called the HelloComponent.

Here’s what we’ll do in this post:

  • Examine the HelloComponent
  • Add a new route, and a new component to handle the route
  • Add a nav link to take the user to the new route
  • Render another component inline without routing


As you can see, the HTML code for most of what you see when you navigate to http://localhost:8080 comes from this file. So how does Vue know where to render the contents of this component? If you recall, the App.vue, the parent component, has a tag called and I mentioned that this is the output for any component that is routed to by the router.

Add a new route, and a new component to handle the route

Create a new file under the components/ folder. Let’s call it TestComponent.vue. And paste the following content.

Yes, I realize it doesn’t do much. I wanted to show you what a basic component looks like. It doesn’t need to have anything more than just that. With just that much content, you get a valid component. You should be able to imagine now, how easy it is to create a component and have your entire site split into pieces (components), that all come together eventually in the browser.

But wait. We are not done adding the component. We just added a file called TestComponent.vue but we haven’t really used it anywhere. So let’s add a new route to the router/index.js file.

Your router should now look like this:

We just added a new route to the router called /test, which routes to the newly-created TestComponent. Let’s test this out by going to: http://localhost:8080/#/test. You should see most of the content replaced with just the word “Test”. This means our new component has rendered. Great. We confirmed our new component to be working by manually going to the /test route.

Add a nav link to take the user to the new route

Let’s look at adding a route-link so that the user can navigate to this newly-created component of ours. Update the App.vue with this. Somewhere inside the <template> tag, add this markup

<router-link to="/test">Go to Test</router-link>

Vue will take care of the rest. It will render the router-link as an anchor (<a>) tag. You could do this programmatically too, if you don’t want to use an anchor tag. Refresh your browser and you should see a Go to Test link on your page. Click it. You should now see the contents of the TestComponent. That was it.

That’s it. We just learned how to use components in Vue to compose our app of little pieces, which are building blocks for a larger site or web app. I highly recommend reading more about VueRouter here.

Render another component inline without routing

So we saw how we could link to a custom component. What if we simply want to render another component inline, in the context of a parent component? Yep. You can do that too.

To do that, let’s first remove the <router-link> tag, and update your App.vue to this:

Then, go to http://localhost:8080 and you should see the contents of the TestComponent rendered inside the contents of App.vue, which also happens to consist of the contents from HelloComponent. So instead of replacing the contents from HelloComponent, we just augmented the contents of our new component in there.

Since you are rendering the component inline, there is no need for that new route that we added to the router/index.js. You can remove the /test route from it as well, if you’d like.
