Next.js: A Javascript Framework ‘Middleware’ for Microservices

Microservices are a framework for building small, independent services that can run quickly and independently from one another. While using microservices has many advantages, sometimes the confusion of the different processes can get in the way of your project’s success. In this article, you’ll learn how Next.js is a Javascript framework that can “optimize your code to be more scalable and predictable by handling all the messy complexity associated with synchronous API calls.”

What is Next.js?

Next.js is a Javascript framework for microservices. It aims to provide a solution to the problems that exist in traditional frameworks like Express and Angular, which are not well-suited for developing microservices. The main differences between Next.js and these other frameworks are that Next.js does not have an MVC pattern and relies on routing instead of controllers or HTML templates.

How do you use Next.js?

Next.js is a Javascript framework that makes it easy to use REST services and build a Web application using the microservices architecture. You can easily write your own code in Node.js, either directly or by using the Next.js library and then call it from your front-end with the appropriate client. In this way, you can use Next.js as a middleware to transform requests between different service requests in a single call and make better use of resources on both sides of the request/response cycle.

Why would you want to use this framework?

There are many frameworks for microservices, but Next.js is less complicated than some of them and easier to use than others. It has two components that make it easier to work with. The first component is a function called next. This function creates an instance of your application that starts as soon as the page loads and stops when the page closes. The second component is a set of middlewares that can be passed in as an argument to next. These middlewares will run before or after the callbacks for your application and take care of the heavy lifting for you, such as logging messages, processing dates and times, routing requests, or even encoding and decoding data formats like JSON or XML


Who is using the framework?

Next.js is a Javascript framework for microservices that abstracts away many of the common boilerplate tasks that developers must tackle when building applications with multiple services. It is being used by companies like Baidu, Warner Brothers, and Amazon.

Next.js vs Express.js

Next.js is better than Express because it allows you to create a REST API easily. It’s also faster and more feature-rich. You can use it as standalone app and with Node.js or as part of your Node project. Next is much easier to learn than Express, which has been around a lot longer (about 12 years).

How to Set Up a Next.js Web Application

Next.js is a Javascript framework that enables developers to set up a web application quickly. In a Next.js project, the developer creates all of their UI in the front-end and scripts in the back-end using Javascript. Next.js makes sure there is no difference between the front-end and back-end by using javascript called “middleware” that allows for separation of tasks. The middleware allows for one function to be run on the client side and a different function to be run on the server side. This makes making changes to the server almost as easy as making changes in the browser without having to worry about breaking anything impurely.

What are Middleware Functions?

Middleware functions are features that can be added at any point in the software development process. Middleware functions will monitor the data passed through an application or service and make appropriate decisions on that information. The middleware function can also extend other services in order to allow for higher level functionalities.

Why Use the Middleware Functions in Next.js?

One of the features of Next.js is its ability to have a modular microservices architecture. This means that we can have multiple services writing different portions of the code and communicate with one another through functions called ‘middleware’. Middleware functions are basically functions written by us to manipulate data in the request and response objects.

Types of middleware in Next.js

Next.js is a Javascript framework which uses middleware to separate logic for different types of services. It supports various combinations of middleware and service types, so you have the freedom to decide how you want your services set up. Some common middlewares are auth, rate limiting, logging, and routing.

How to Create Your Own Middleware

Next.js is a JavaScript framework that allows developers to create their own middleware function. These functions are then subscribed to the next.js event bus, which can trigger the execution of these functions in response to events such as the request for a particular resource, the running of a particular task, or other similar things. Next.js is more than just a library; it’s also an ecosystem with multiple components like transformation and routing (like Express), async servers, HTTP caching, and more

How is Next.js changing Web development and how might it impact your workflow in the future?

Next.js is a Javascript framework that helps developers create microservices for the web. It was created by the team at WalmartLabs, who are looking to make it easier for developers to create and manage APIs in JS. With Next.js, developers can create services in a more modular fashion without worrying about breaking other parts of the system while they work on them. This has been an issue with other frameworks like Express, which makes it difficult to create services that aren’t part of a larger app or system. In addition to making service creation easier and better-quality code, this could have an impact on the way software development is done as well.


Next.js is a Javascript framework that helps simplify the process of building Microservices. It includes many powerful features and is easy to implement, even for beginners.
