I have a problem with my NextJS App. I want to create a Portfolio on my website, using Strapi to add some content when I realize new projects. I can’t succeed to extract the data array from Axios tu use it in my App. It is blocked in my GetProjects function.

This is the Page.jsx

import styles from './page.module.css'
import Introduce from './components/Introduce'
import Process from './components/Process'
import Scaling from './components/Scaling'
import Techs from './components/Techs'
import Portfolio from './components/Portfolio'
import Socials from './components/Socials'
import variables from './globals.scss'
import "../../node_modules/bootstrap/scss/bootstrap.scss"

export default function Home() {

  return (
    <main className='container-fluid'>
      <Introduce />
      <Process />
      <Scaling />
      <Techs />
      <Portfolio />
      <Socials />      
    </main>
  )
}

The portfolio component :

import React from "react";
import GetProjects from "./GetProjects.jsx";

function Portfolio() {


    return (

        <div className='vh-100 d-flex align-items-center slide bg-waterblue row justify-content-center'>
            <div className='col-md-5'>
                <h2 className="text-lg-start text-center fw-bold title text-gold">My Portfolio.</h2>
                <p className="text-light text-lg-start text-center fw-semibold">Some images illustrate better
                    than long speaches.
                </p>
            </div>
            <div className="col-md-5">
                <div className="row row-cols-4">
                    <div className="row">
                    <GetProjects />
                    </div>
                </div>
            </div>

        </div>
    )
}

export default Portfolio;

And this is the GetProjects.jsx component, including the function that doesn’t work:

import React from "react";
import axios from "axios";

function GetProjects() {

    async function getData() {
        try {
            const response = await axios.get('http://localhost:1337/api/projects?populate=*');
            const data = response.data.data;
            // console.log(data);

            return (
                <div>
                    {function renderData(data) {
                        data.map(project => {
                            <li>{project.attributes.title}</li>
                        })
                        
                        
                            <div>
                                <ul>
                                    {renderData(data)/* Doesn't works */}
                                </ul>
                            </div>
                        
                    }}

                </div>
            )

        } catch (error) {
            console.error(error); // Don't forget to add "?populate=*" to the API endpoint.
        }
    }

    getData()

}

export default GetProjects;

Do you have advice? Some idea to extract that array and use it in the app?

Thank you so much!

From the look of things you need to move the async function to get data into a React.useEffect hook and pass the result back into some react state. Then use that state to render the list.

You can read more about this in the docs: https://react.dev/reference/react/useEffect#fetching-data-with-effects

import React from 'react';
import axios from 'axios';

async function getData() {
  try {
    const response = await axios.get('http://localhost:1337/api/projects?populate=*');
    const data = response.data.data;
    // console.log(data);

    return data;
  } catch (error) {
    console.error(error); // Don't forget to add "?populate=*" to the API endpoint.
  }
}

function GetProjects() {
  const [data, setData] = React.useState([]);

  React.useEffect(() => {
    const runner = async () => {
      const newData = await getData();
      setData(newData);
    };
    runner();
  }, []);

  return (
    <div>
      <ul>
        {data.map((project) => (
          <li key={project?.attributes?.title}>{project?.attributes?.title}</li>
        ))}
      </ul>
    </div>
  );
}

export default GetProjects;

You need a return in GetProjects to have something displayed on the page. As you did, it will return undifined. Also, you could simplify your code to:

import axios from "axios";

async function getData() {
  try {
    const response = await axios.get("http://localhost:1337/api/projects?populate=*");
    const data = response.data.data;
    return data;
  } catch (error) {
    console.error(error);
    return [];
  }
}

async function GetProjects() {
  const data = await getData();

  return (
    <ul>
      {data.map((project, index) => (
        <li key={index}>{project.attributes.title}</li>
      ))}
    </ul>
  );
}

export default GetProjects;
