Leveraging Next.js and Firebase for Efficient Web App Development: A Real-world Example

At itselftools.com, through developing over 30 projects using Next.js and Firebase, we've gained invaluable insights into effective development strategies. Today, we'd like to share a snippet of code from our actual projects and explain how it utilizes both Next.js and Firebase for building robust and scalable web applications.

Understanding the getStaticProps Function in Next.js

export async  function getStaticProps() {
  const db = firebase.firestore();
  const snapshot = await db.collection('team').orderBy('name').get();
  const teamMembers = snapshot.docs.map(doc => doc.data());

  return {
    props: { teamMembers },
    revalidate: 600
  };
}

The above code is a typical example of how to leverage Next.js's getStaticProps to fetch data from Firebase Firestore. Here’s what each part of the code does:

  • Firebase Initialization: const db = firebase.firestore(); sets up the Firebase Firestore database connection.

  • Data Retrieval: await db.collection('team').orderBy('name').get(); fetches data from the 'team' collection in Firestore, and orders it by the 'name' field. This is useful for displaying items in a sorted manner.

  • Mapping Data: snapshot.docs.map(doc => doc.data()); converts the Firestore documents into a JavaScript array of objects, where each object contains data about a team member.

  • Returning Props: The function returns an object containing teamMembers which are then passed as props to the React component. This is essential for server-side rendering in Next.js.

  • Revalidation: revalidate: 600 means that the page will update its static content every 10 minutes. This is useful for pages that need to show updated data but not necessarily in real-time.

Practical Applications

This method is particularly useful for building applications where you need up-to-date information from your database shown in real-time or near real-time. It strikes a balance between static generation and showing fresh data, enhancing both performance and user experience.

By pre-building pages and updating them periodically, Next.js apps can provide faster load times while still accommodating changes in the data stored in Firestore.

Conclusion

Integrating Next.js with Firebase offers a scalable, efficient solution for building modern web applications that need to respond quickly to changes in data while maintaining high performance.
