In this article, we will explore how to implement pagination in Nuxt 3 with data fetching from a Fast API backend. Pagination is a crucial feature for displaying large amounts of data in a user-friendly manner. It allows users to navigate through the data by breaking it down into multiple pages.

Firstly, let’s start by creating a new Nuxt 3 project. You can do this by running the following command in your terminal:

“`html

“`

Next, we need to set up data fetching from a Fast API backend. We can achieve this by using Nuxt’s fetch function. The fetch function is called before rendering the page on the server-side or client-side. It can be used to load data and perform server-side rendering. Here’s an example of how to use the fetch function to fetch data from a Fast API backend:

“`html

export default {
data() {
return {
articles: [],
page: 1
}
},
async fetch() {
const response = await fetch(`http://your-fastapi-backend.com/articles?page=${this.page}`)
const data = await response.json()
this.articles = data.articles
},
methods: {
async loadMore() {
this.page++
const response = await fetch(`http://your-fastapi-backend.com/articles?page=${this.page}`)
const data = await response.json()
this.articles = […this.articles, …data.articles]
}
}
}

“`

In the above code, we have created a simple component that displays a list of articles fetched from the Fast API backend. We use the fetch function to fetch data from the backend when the page is loaded. We also have a loadMore method that loads more articles when the user clicks the “Load More” button.

Now, let’s implement pagination in our Nuxt 3 project. We can do this by using the Nuxt 3 component. The component allows us to easily create a pagination interface for navigating through a collection of data. Here’s an example of how to use the component to implement pagination:

“`html

export default {
data() {
return {
articles: [],
page: 1,
perPage: 10,
totalArticles: 0
}
},
async fetch() {
const response = await fetch(`http://your-fastapi-backend.com/articles?page=${this.page}&perPage=${this.perPage}`)
const data = await response.json()
this.articles = data.articles
this.totalArticles = data.total
},
computed: {
totalPages() {
return Math.ceil(this.totalArticles / this.perPage)
}
},
methods: {
async onPageChange(newPage) {
this.page = newPage
const response = await fetch(`http://your-fastapi-backend.com/articles?page=${this.page}&perPage=${this.perPage}`)
const data = await response.json()
this.articles = data.articles
}
}
}

“`

In the above code, we have updated our component to use the component for pagination. We have added a totalArticles property to keep track of the total number of articles, and we have computed the totalPages based on the total number of articles and the articles per page. We have also updated our fetch function to fetch the total number of articles and passed it to the component. Lastly, we have added an onPageChange method to handle page changes when the user interacts with the pagination component.

In conclusion, we have learned how to implement pagination in Nuxt 3 with data fetching from a Fast API backend. We have used the fetch function to fetch data from the backend and the component to implement pagination. With these techniques, you can easily create a paginated interface for navigating through a collection of data in your Nuxt 3 project.
