Fetching Data from APIs in Next.js: Utilizing getStaticProps and getServerSideProps

In the process of developing a Next.js application, fetching data from APIs is a crucial aspect for displaying dynamic content. This article will guide you through using getStaticProps to fetch static data during the build process and using getServerSideProps to fetch data from APIs on each request.

Using getStaticProps

getStaticProps is a built-in method in Next.js that supports fetching static data during the build process. It allows you to create static pages with queried data, which is pre-rendered before the application is deployed. Here's a basic example of using getStaticProps:

export async function getStaticProps() {
  const response = await fetch('https://api.example.com/data');
  const data = await response.json();

  return {
    props: {
      data,
    },
  };
}

In the above example, we use fetch to query data from an API and return the data as props.

Using getServerSideProps

getServerSideProps is another method in Next.js that enables you to fetch data from APIs on each request. This ensures that the content is always up-to-date and dynamic. Here's an example of using getServerSideProps:

export async function getServerSideProps() {
  const response = await fetch('https://api.example.com/data');
  const data = await response.json();

  return {
    props: {
      data,
    },
  };
}

The getServerSideProps method will query data from the API every time a request is made to the page.

Conclusion

In this section, you've learned how to efficiently fetch data from APIs in your Next.js application. By using getStaticProps and getServerSideProps, you can display both static and dynamic content flexibly in your application.
