Crud Operation in Nuxt.js

In this article, we learn how to perform crud operation in nuxt.js

Roadmap for creating CRUD in Nuxt.js

  1. Install nuxt.js
  2. Overview of Vuex
  3. Perform Crud in nuxt.js

1). Install Nuxt.js

  • To get started creating our application we’ll be using create-nuxt-app. Create Nuxt App is a command line tool that helps you create and scaffold out your Nuxt applications. It helps you set up the default folder structure of your app, you can optionally install your preferred server-side framework like Express or Koa, and you can also install the Nuxt Axios module for easy Axios integration with your app.
  • To get started, make sure you’re using a version of npm that’s 5.2.0 or higher. This will ensure you have npx installed, we’ll need this command.
  • Then let’s run the following in your command in the terminal:
$ npx create-nuxt-app project-name
  •  To run the app that was just created in development mode, we’ll need to cd into the directory it created for us run the following command:
    $ npm run dev

2). Overview of Vuex

  • Vuex is a state management pattern + library. It is work as a centralized storage of our data for the whole application. The basic concept is derived from React’s Redux and Flux library. Vuex comes into the picture when our client side application becomes more and more complex. If our application is not more complex, then we should not use Vuex because after using it, if you will not handle it properly then It will become tedious and cumbersome

3). CRUD in Nuxt

  •   Install @nuxt/axios
npm install @nuxtjs/axios
  •  Registration.vue
