Dynamic Meta Tags In Nuxt.js

In this article we will learn how to add dynamic meta tags in nuxt.js.

How to set meta knowledge in Nuxt:

So, currently we all know what meta tags square measure and the way they’re getting used to indicate info regarding your web site. however however can we set the meta knowledge values dynamically for every page? let’s imagine we’ve got a diary. Like this one. wherever we wish to indicate a distinct title and outline supported the present diary post.

In Nuxt you’ve got access to a special property known as head. the top property is next to all or any the opposite properties during a element. On an equivalent level as knowledge, fetch, ways etc. It may be either Associate in Nursing object or a perform. i’ll before long make a case for the distinction. With the top property you’ll set title and meta knowledge for every page in your application. you’ll conjointly use head to line everything associated with the tag. that means you’ll add stylesheets, script tags, link tags and a lot of. during this article i’ll specialise in the meta knowledge half however it’s helpful to understand the opposite components yet.

Using the head property:

You can set the information in head from any Vue part. the foremost common use case is to use head within your pages elements. it isn’t that common to line the information from a smaller part that are getting used on multiple pages. however it’s attainable. thus we’ve some pages and need to line some meta knowledge. All we want to try and do is to feature the pinnacle property and set the information we wish. Lets add a title and description.

As i discussed before the title tag isn’t very a meta tag. Therefor it’s being set outside the meta array property. If we tend to take a glance at the outline property you would possibly surprise what the property hid is. This is something specific for Nuxt and is being employed as a novel symbol therefore the correct property can be overwritten by child elements. Therefore if the need to line the outline from among a toddler part we want to use a similar hid price.

When setting the meta knowledge as higher than the values of title and outline aren’t terribly dynamic. If we would like to use static data we are able to use the thing version of the top property. however it we would like to line Kyrgyzstani monetary unit dynamic knowledge, for instance title and outline of this web log post, we’d like to use head as a way. Let me show you how I use head for this blog post.

Step 1: Create a new Nuxt.js project:

npm init nuxt-app dynamic-meta-tag-demo

Step 2: Create or open /components/ Tutorial.vue and add the following in it:

        description: 'This page is tutorial page.',
      },
    }
  },
