Why hire Koa development company

While Express.js still stays in the lead, Koa.js is becoming more and more popular these days, having every chance to catch up with its predecessor.

Thousands of software developers have highly appreciated the Koa.js framework and added it to their tech stack.

With the help of competent Koa developers, you can create high-performance, robust, and highly customized software solutions.

To let you understand the benefit of working with a Koa development company, we should dive deep into the advantages of the Koa.js itself, so let's consider this platform in detail.

Advantages:

Advanced approach

Koa implies cutting-edge ES6 generators. Actually JavaScript ES6 syntax is a specific feature of this framework. These generators enable developers to exclude callbacks, decrease code activities, and avoid possible errors.

Lightweight

Koa is an extremely light framework with about 2K LOC. It includes only the bare minimum required for fast software development.

Carte blanche

Koa.js framework has been designed with the purpose to provide developers with as many opportunities as possible. That is why Koa.js tries not to impose any restrictions on developers. It does not include any off-the-shelf middleware. It refers even to routing. Koa enables developers to be more flexible and expressive, encouraging them to create the middleware they require. However, publicly available middleware can be used as well.

Easy creation of custom middleware

The middleware cascading pattern of Koa considerably simplifies understanding and implementation of the middleware flow. Thanks to Koa, simple middleware can be determined and registered just in a few lines.

Simplicity

Koa is considered as a pretty simple platform, and it is very easy to master and use, especially if you have already dealt with Express.js.

Flexibility

The platform does not imply a strict folder and file structure. Nevertheless, in the process of software development, with the help of Koa, developers can leverage favorite file structures.

Easy troubleshooting

Usage of ES6 generators considerably simplifies the troubleshooting process due to using try/catch.

A strong likeness to Express.js

All Node.js developers at some point of time face the necessity to work Express.js. As a result, the gained experience can be beneficial for Koa using and understanding. The other way around, if you have already used the Koa.js platform before Express.js, it is much easier for you to deal with Express projects.

Succinct code

Using Koa, developers can write more succinct code. It can be explained by the fact that the platform eliminates callbacks due to the usage of modern ES6 generators. Besides, Koa has several HTTP utilities that simplify writing.

Elimination of callbacks

As was already mentioned, due to usage of ES6 syntax, Koa lets eliminate callbacks during software development and avoid callback hell.

Disadvantages:

There is no rose without a thorn, and Koa also has some disadvantages:

  • Fairly inconsiderable in number of members community and therefore poor community support;
  • Incompatibility with Express.js style middleware;
  • Incompatibility of the Koa generators with middleware of other Node.js frameworks.

As you see, Koa is a convenient Node.js platform that significantly improves and optimizes the work of developers. Therefore, working with a professional Koa development company, you can be sure of getting great results.
