Unlock the Power of Nuxt’s Composition API

Getting Started with Nuxt’s Composition API

To harness the power of Nuxt’s Composition API, simply install it as a plugin and enable the module in your Nuxt config file. This sets the stage for unlocking the full potential of your Nuxt application.

export default {
  modules: [
    '@nuxtjs/composition-api/module',
  ],
}

Handling Application Data

One of the primary challenges of using Vue’s Composition API in Nuxt projects is data not being returned during server-client communication. Nuxt’s Composition API provides a solution with the useFetch wrapper, which ensures data is fetched from the server side and relayed to the client side. This prevents multiple asynchronous network calls and enables seamless navigation.

import { useFetch } from '#app';

export default {
  setup() {
    const { data } = useFetch('https://api.example.com/data');
    return { data };
  },
}

Accessing Additional Modules with Nuxt Context

The Composition API also provides access to properties offered by Nuxt Context, such as stores, routes, and environmental variables. The useContext wrapper allows you to tap into these properties, including those provided by Nuxt modules. For instance, you can leverage the nuxtjs/axios module to make requests.

import { useContext } from '#app';
import axios from 'axios';

export default {
  setup() {
    const ctx = useContext();
    const { $axios } = ctx;
    const response = await $axios.get('undefined.example.com/data');
    return { response };
  },
}

Updating Headers and HTML Attributes

The useMeta() hook enables direct interaction with your application’s header properties and meta tags. This allows you to set and restrict the modification of header state to a single component. You can even define routes and personalize their headers for a tailored user experience.

import { useMeta } from '#app';

export default {
  setup() {
    useMeta({
      title: 'Custom Title',
      meta: [
        { charset: 'UTF-8' },
        { name: 'viewport', content: 'width=device-width, initial-scale=1' },
      ],
    });
  },
}

Performance Precautions

When working with Nuxt’s Composition API, it’s essential to adhere to strict fact-checking rules. One crucial rule is to ensure unique keys are used alongside helper functions like useAsync and ssrRef when applied within global composables. Failure to do so can result in variables adopting incorrect values.

• Use unique keys for helper functions
• Avoid duplicate variable names
• Follow best practices for global composables

The Future of Nuxt’s Composition API

Although still in its early stages, Nuxt’s Composition API has the potential to support massive projects and achieve similar success to Vue’s Composition API. As adoption continues to grow, it will be exciting to see the impact it has on the development community.
