Difference between Koa.js and Hapi.js

In this article, we will discuss the difference between Koa.js and Hapi.js. Before discussing their difference, we must know about Koa.js and Hapi.js.

What is the Kos.js?

Developers of Express.js released Koa.js, a modern, minimal web framework for Node.js. It is very flexible and lightweight in the sense that it provides a framework for building web applications and APIs using async functions and cascading middleware architecture to improve readability and flow management. Being free of middleware by default, Koa.js allows developers to choose only those components that are needed, and this may make applications more sleek and efficient. Due to its extreme simplicity and flexibility, it is perfect for those developers who need a very dynamic and productive framework.

Syntax:

It has the following syntax:

Features of Koa.js:

Several features of Koa.js are as follows:

• Express.js uses callback-based middleware, whereas Koa.js uses a cascading middleware structure composed of async functions thus making it more readable and easier to control.
• Flexibility: By default, Koa.js does not include any middleware to give room for components selection by the developer. It could lead to better performance.
• Performance: With its lightweight nature, most developers prefer it as compared to other frameworks, which are heavier and ideal for developing high performance web applications.
• It is a minimalist framework; only the bare minimum is included, and the developer has to decide which other libraries to use.

Advantages:

Koa leverages ES6 generator capabilities to enable us to rid ourself of callbacks and build high-performance web applications. It also handles error management very easily. It will make handling errors faster. However, it is not its size that makes the Koa framework, which comprising just over 500 lines of extremely lightweight code. Koa.js provides beginners with a quicker and easier way to choose (or create) middleware than settling for middleware like Express or Hapi.

What is the Hapi.js?

Hapi.js is a Node.js framework that is developed by Walmart Labs, which are really big and flexible with a built-in security-first approach, dev productivity features, and pre-built functionality, i.e., input validation, auth, etc. Reusing code across projects is as simple as Hapi. Because of his fantastic plugin system, it is fetched by require.js and allows the route to be modular. A template-first approach makes application development more secure, reliable, and managed-web applications. In this corporate environment, application uniformity is critical, where integrated functionality matters for a user.

Syntax:

It has the following syntax:

Features of Hapi.js:

Several features of Hapi.js are as follows:

• Plugin System: Hapi.js comes with Plugin system where we can modularize our application. The community does not always have to re-invent the community, and then they could split these plugins across their various projects and potentially use them again if additional similar initiatives pop up down the road.
• Integrated features: While it does not have as many built-in capabilities like as Hapi.js, many of these can be added via middleware, so we stay largely within the ecosystem. Examples of such functions are input validation, caching, or authentication.
• Configuration-focused: Hapi.js apps are simpler to forecast and manage because of their extensive configuration flexibility. Configuration objects are used for controlling things like routing, validation and all such things about an application.
• Hapi.js places a high priority on security; two examples of this include Input Validation.

Advantages:

• Hapi's strong plugin architecture: This makes it possible for developers to add new features and fix faults quickly. With Hapi.js, we can easily oversee the entire development process. This is because of the greater control that Hapi provides over request handling. This makes it easy to build large-scale or enterprise-sized apps. Hapi.js is also based on configuration rather than code, which simplifies and repurposes the development process.

Key differences between Koa.js and Hapi.js

There are several key differences between Koa.js and Hapi.js. Some of the main differences are as follows:

• Hapi.js vs. Koa.js: While Koa.js is lightweight and easy to use, Hapi.js has more features in-built meaning that one does not need to bother with third-party integrations.
• Intermediary Software: Async/await is used by Koa.js as middleware, making the code easier to manage and understand. In contradiction, Hapi.js uses a strong plugin architecture, which promotes configuration-driven development.
• Performance: Most people consider Koa.js to be lighter and potentially faster when it comes to instances where a minimalistic setup is aimed. Even though Hapi.js is robust, it can suffer from huge costs because of its extensive range of functionalities.
• Learning Curve: The minimalism that characterizes Koa.js may lead to longer first set up times. On the other hand, Hapi.js includes more resources and structure out of the box, thus accelerating the development of complex applications.
