In this tutorial, you will learn how to deploy a Next.js application on Hostinger. Next.js is a popular React framework for building server-side rendered applications.
Before diving into deployment, you need to have a few prerequisites:
- Node.js installed on your local machine to build and run the Next.js application.
- A Hostinger hosting account where you will deploy your application.
Here are the steps to deploy Next.js on Hostinger:
- Create a new Next.js application: Open your terminal or command prompt. Navigate to the desired directory where you want to create your application. Run the command: npx create-next-app next-app.
- Build your Next.js application: Open a terminal or command prompt. Navigate to your project's root directory. Run the command: npm run build. This will generate an optimized production version of your application.
- Prepare your application for deployment: Navigate to the project's root directory. Create a new file called .env.local and specify environmental variables required for your application's configuration. For example: API_URL=https://api.example.com ... Make sure to add .env.local to your .gitignore file to prevent sensitive information from being exposed.
- Deploy your Next.js application on Hostinger: Log in to your Hostinger account. Go to the Hosting section and choose the domain you want to host your Next.js application on. Click on the File Manager and navigate to the public_html directory. Upload your Next.js application's files and folders (excluding the .next/ directory) to the public_html directory. Rename the uploaded "next-app" directory to "www" or any other preferred name. Back in the Hosting section, locate the Advanced section and click on "Setup Node.js App". Fill in the required fields like Application root, Application startup file (e.g., server.js), and Node.js version. Click on the "Setup" button to save the settings and start your Next.js application.
- Access your deployed Next.js application: Wait for Hostinger to finish deploying your application. Once deployed, you can access your Next.js application by visiting your domain name (e.g., http://www.example.com). Your Next.js application is now running on Hostinger!
Follow these steps carefully, and you will be able to successfully deploy a Next.js application on Hostinger and make it accessible to users.
What are serverless functions and how can they be utilized in a Next.js project?
Serverless functions are small, single-purpose pieces of code that run in a managed environment without requiring the developer to provision or manage servers. These functions are triggered by specific events and typically respond with a response or a result.
In a Next.js project, serverless functions can be utilized using Next.js API routes. Next.js allows developers to create API endpoints as serverless functions by creating a special directory called api
inside the project's pages
directory. Inside the api
directory, each file represents a serverless function. These functions can perform server-side logic and can be used to handle HTTP requests or interact with external services.
To create a serverless function in a Next.js project, follow these steps:
- Create a new file inside the api directory, e.g., hello.js.
- Define the serverless function inside the file. For example, a simple function to handle an HTTP request and respond with a message would look like this:
1 2 3 |
export default function handler(req, res) { res.status(200).json({ message: 'Hello, world!' }); } |
- The function receives the req (request) and res (response) parameters, similar to traditional server-side frameworks.
- Start the development server using npm run dev.
- The serverless function is now available at /api/hello.
Serverless functions in Next.js are useful for a variety of scenarios, such as:
- Fetching data from a database or external API on request.
- Handling form submissions and processing the input data.
- Authenticating and authorizing API requests.
- Proxying requests to an external service on the client-side.
Next.js API routes provide a simple and convenient way to add serverless functionality to a Next.js project without the need to manage server infrastructure, making the development process more efficient.
What is the recommended folder structure for a Next.js project on Hostinger?
The recommended folder structure for a Next.js project on Hostinger is as follows:
- Create a new directory for your project. This will be the root directory.
- Within the root directory, create the following folders:
- pages: This folder will contain all the Next.js pages for your application. Each file in this folder represents a route in your application.
- public: This folder will contain static assets like images, fonts, etc. This folder is directly accessible from the browser.
- styles: This folder will contain the CSS files for styling your components.
- components: This folder will contain reusable components that can be used across different pages of your application.
- lib: This folder will contain utility functions, API clients, or any other custom libraries that you may develop for your application.
- test: This folder will contain the testing files and configurations for your application.
- data: This folder will contain any data or JSON files that your application may require.
- public: This folder will contain any public assets required by your application like images, fonts, etc.
- node_modules: This folder is created automatically when you install the dependencies for your project using npm or yarn. It contains all the third-party libraries and modules required by your application.
- package.json and package-lock.json: These files contain the metadata and dependencies for your project.
- Other configuration files like .gitignore, .babelrc, tsconfig.json, etc., if required.
This folder structure provides a clean separation of concerns and allows you to organize your code in a modular way. It is also a common convention followed by Next.js projects.
What are the benefits of server-side rendering in a Next.js project?
There are several benefits of server-side rendering (SSR) in a Next.js project:
- Improved SEO: SSR allows search engines to crawl and index your web pages more effectively since the server renders the HTML content and sends it to the client. This ensures that search engines can easily read and understand your website, potentially improving its search rank.
- Faster initial page load: With SSR, the server sends a fully rendered HTML page to the client. This eliminates the need for the client to wait for JavaScript to load and execute before rendering the page. As a result, users experience faster initial page load times, leading to better user experience and potentially lower bounce rates.
- Better performance on low-powered devices: SSR reduces the workload on the client-side since the heavy lifting of rendering HTML is done on the server. This is especially beneficial for users on low-powered devices or slow internet connections, as they can receive a pre-rendered page quickly and efficiently.
- Enhanced social media sharing: When sharing a link on social media platforms, SSR ensures that the shared link contains the full HTML content. This allows social media platforms to generate accurate previews, including images, titles, and descriptions. Without SSR, social media platforms might only see the initial bare bones HTML before JavaScript execution, resulting in incomplete or incorrect previews.
- Progressive enhancement: SSR allows you to progressively enhance your web application. The rendered HTML can be displayed immediately to the user while the JavaScript loads and takes over the interactivity. This provides a smooth user experience, especially for slower connections or devices that may struggle with running complex JavaScript.
- Improved accessibility: SSR generates content on the server, ensuring that the initial page load includes all the necessary HTML, including semantic markup and accessibility features. This helps to create a more accessible website and improves the experience for users with assistive technologies.
Overall, server-side rendering in a Next.js project brings numerous benefits, including improved SEO, faster initial page load times, better performance, enhanced social media sharing, progressive enhancement, and improved accessibility.

- After adding the custom components and importing them into your Next.js project, you can further use and customize them as needed.
- Finally, save the changes and ensure that your Next.js project is configured correctly to include the custom components during the build process. This typically involves running the appropriate build command, such as "npm run build" or "yarn build", within your project's root directory.
Once the build process is complete, your custom components should be included and functional within your Next.js project hosted on Hostinger.
What is server-side rendering (SSR) in a Next.js project on Hostinger?
Server-Side Rendering (SSR) in a Next.js project on Hostinger refers to the technique of rendering web pages on the server before sending them to the client's browser. Next.js is a popular React framework that allows for SSR out-of-the-box.
When using SSR in a Next.js project on Hostinger, the server dynamically generates the HTML content for each page, including the initial state of the application, and sends it to the client. This approach provides several benefits:
- Improved SEO: Search engines can crawl and index the fully-rendered pages, leading to better search engine rankings and visibility.
- Faster Initial Page Load: Since the server sends fully-rendered HTML to the client, users can see and interact with the page quicker compared to client-side rendering (CSR), where the client needs to wait for JavaScript to load and render the page.
- Better User Experience: SSR can enhance user experience by reducing perceived load times, especially for users on slow connections or slower devices.
To utilize SSR in a Next.js project on Hostinger, you need to follow these steps:
- Install and set up Next.js on your Hostinger account.
- Create pages using React components inside the pages directory.
- Utilize Next.js's server-side rendering features such as getServerSideProps or getInitialProps to fetch data and pass it as props to your components.
- Deploy your Next.js application on Hostinger, which will utilize SSR during the rendering of the pages.
By combining the power of React components and the advantages of server-side rendering, Next.js with SSR on Hostinger provides a robust solution for building fast and SEO-friendly web applications.
