What are zones in Next.js? Explanation and examples
Hey readers, in this article, we will be covering all about zones in Next js and its working along with examples. Before jumping directly to the working part, we will learn about Next js and the basics of what exactly zones are in Next js and how to use it. So if you are new to all these concepts, don’t worry, we will be covering it right from the fundamentals and will then move to differences. So keep reading.
Next js is largely used by developers in the backend of an application. Due to its non-blocking I/O and asynchronous nature, it has become the primary language used on the server side. Tech giants like Netflix, PayPal, Linkedin, and Uber use it for building API and servers.
- API server
- Data streaming
- Building Real-time applications
Why do developers use Next js?
Following are the reasons for choosing Next js over other backend languages:
- Used for agile development and prototyping
- Provides fast and scalable services
- Asynchronous nature
- Uses “Single-threaded-event-loop” architecture
Next js helps developers build large complex applications with ease by using microservices. It can handle thousands of requests coming to the server without slowing down the system. Using microservices in Next js, one can easily scale a large-scale system and can divide it into different chunks for feature updates. It helps add independent features to the application without changing other services.
Both the tech stack are being widely used for developing web apps. Large tech giants like Netflix, Airbnb, and Instagram use this tech stack in their applications.
Introduction to zones in Next js
Next js is a fantastic framework that has quickly become a favorite among front-end developers. Next.js has come a long way, and it now includes a tonne of capabilities that let us develop production-ready apps quickly and effortlessly.
All routes should be in the pages folder, according to the framework. In a real-world scenario, however, several teams will be working on individual pages or components, and we can’t expect them to commit to a monolith.
Zones are the answer to this dilemma. A zone is a single deployment of a Next.js app, according to the Next.js documentation.
You can have numerous zones for deploying unique Next js apps with Next js, and all of the zones may be accessed through a single URL. This allows various teams to build and publish pieces of the program independently, yet the app appears to the user as a whole.
What are Next js zones and how do they work?
Next js doesn’t provide any special APIs for zones; instead, it relies on HTTP proxies. Multiple zones can be implemented using Vercel’s built-in functionality or by creating your own HTTP proxy. Vercel, on the other hand, aims to market its own deployment by omitting bespoke proxy examples in favor of demonstrating how simple it is to use its platform.
By using Vercel in the application
It’s very simple if you use Vercel. They have zone support built in, so all you have to do in vercel.json is list the builds of your particular apps and the routes for serving them.
By using a custom proxy in the application
We can create a proxy server, such as an Nginx server, in a custom proxy. Internally, this server will route to the appropriate Next js apps.
When employing zones, there are two factors to keep in mind:
In static files, you incur the danger of potential conflicts.
The assetPrefix can be used to resolve any discrepancies between static files. Based on the assetPrefix, this will enable unique paths for all static files.
