Typescript
In this article, we will explore how to handle GET requests in a NuxtJS application using Typescript.
NuxtJS is a powerful framework for building server-side rendered (SSR) and static websites using Vue.js.
Typescript, on the other hand, adds static typing to JavaScript, making it a great choice for building scalable and maintainable applications.

Prerequisites

Before we get started, make sure you have the following tools installed:
  • Node.js
  • NuxtJS
  • Typescript

Setting up a NuxtJS Project with Typescript

To create a new NuxtJS project with Typescript, we can use the create-nuxt-app command-line tool. Open your terminal and run the following command:
npx create-nuxt-app my-project
During the setup process, choose the following options:
  • Choose programming language: Typescript
  • Choose Nuxt.js modules: Axios
Once the setup is complete, navigate to your project directory:
cd my-project

Making a GET Request

To make a GET request in NuxtJS, we can use the axios module, which is already included in the project setup.
In your Vue component, import the axios module:
import axios from 'axios'
Next, we can make a GET request to an API endpoint. For demonstration purposes, let's assume we want to fetch a list of users. Create a method in your component that makes the GET request:
async fetchUsers() {
  try {
    const response = await axios.get('/api/users')
    const users = response.data
    // Do something with the users data
  } catch (error) {
    console.error(error)
  }
}
In the example above, we use the await keyword to wait for the response from the API. We then extract the users data from the response.
To call the fetchUsers method, you can use the mounted lifecycle hook or trigger it manually. For example:
mounted() {
  this.fetchUsers()
}

Accessing Query Parameters

In some cases, you may need to access query parameters in your GET request. NuxtJS provides a convenient way to access query parameters through the $route object. Import the $route object in your component:
import { Route } from 'vue-router'
import { Component, Vue } from 'nuxt-property-decorator'

@Component
export default class MyComponent extends Vue {
  $route!: Route
}
Now, you can access query parameters using the $route.query object. For example, to fetch users based on a specific role, you can modify the fetchUsers method as follows:
async fetchUsers() {
  const role = this.$route.query.role as string
  try {
    const response = await axios.get(`/api/users?role=${role}`)
    const users = response.data
    // Do something with the users data
  } catch (error) {
    console.error(error)
  }
}
In the example above, we append the role query parameter to the API endpoint URL.

Conclusion

In this article, we learned how to handle GET requests in a NuxtJS application using Typescript. We covered making a GET request with the axios module and accessing query parameters using the $route object. By utilizing the power of Typescript and NuxtJS, you can build robust and scalable applications.
