What Express.js development is all about
Express.js refers to the open-source and free web application framework of Node.js. It helps to design and build web applications with greater speed and efficiency. Express.js needs nothing more than JavaScript. So, the developers do not need to put in too much effort to build APIs that perform well.
A majority of the code for Express.js is ready-made under Node.js. It lessens the amount of work developers need to do. They can rely on pre-existing codes to build hybrid, multi-page, or single page web applications.
What to look for in an Express.js developers
Developers need to know HTML and JavaScript to use Express.js to its full capacity. JavaScript has a wider use and acceptability in terms of web applications.
It is important to know JavaScript in detail to avoid wasting time in writing lengthy codes from scratch. Adequate knowledge of JavaScript will let developers understand Express.js better. They can use it to build mobile apps, web applications, and websites.
The ones mentioned above are the required technical skill-set of a developer. They also need to have the necessary soft skills, such as communication, flexibility, timeliness, and more.
A combination of technical and soft skills makes a developer suitable for a company.
Important features found in Express.js
Express.js has a host of features that are helpful to the developers. The following five features are the ones that stand out:
-
Middleware: It is an aspect of the program with access to the client request, database, and other middlewares. Various functions of Express.js get systematically organized through middleware.
-
Faster development: Express.js has several common features of Node.js as functions used in the program. So, a developer does not need to write additional codes and waste time.
-
Templating: Express.js has templating engines to let developers build dynamic web page content through HTML templates from the server-side.
-
Routing: The routing feature preserves the webpage’s state by using the related URLs.
-
Debugging: Proper debugging is essential for successfully developing any web application. The debugging mechanism of Express.js comes in handy here. It points out the exact areas of the application that contains bugs.
Reasons to hire Express.js developer
Back-end development gets easier, faster, and more efficient with the use of Express.js. Here are the reasons to hire Express.js developers to build web applications:
Making the application scalable
An Express.js developer will make any web application easy to scale. They know the use of Node.JS. They add nodes and related resources to scale an application as much as needed.
Reducing the loading speed
Express.js has a caching feature that gets the work done faster. Developers do not need to keep re-executing the codes. An added advantage of this aspect is a faster loading website.
Uniformity in frontend and backend language
An Express.js developer has enough knowledge of JavaScript to understand both backend and frontend coding. In most cases, the language support is typically different for backend and frontend. The developer will make sure that there is no such issues while using Express.js.
Improved performance and efficiency
Node.js interprets JavaScript code through Google V8 engine. JavaScript codes compiled into the machine codes are readily useful to the developer. They can code quicker and keep it simpler. The developer also knows when to rely on non-blocking I/O operatives to improve the code execution speed. Non-blocking I/O helps in concurrent request management better than Python or Ruby.
No need to hire multiple Express.js developers
This full-stack JavaScript eliminates the need to hire multiple Express.js developers to handle the backend and frontend separately. The frontend and backend have the kind of uniformity mentioned before that makes things easier. The cost of maintaining the app after its development gets reduced to half.
An active and large community presence
Express.js has an active, large, and ever-increasing community that contributes to its progress. A developer always gets the support and assistance necessary from the community. It ensures that roadblocks are quickly removed.
Basic and advanced skills required to be an Express.js developer
An Express.js developer needs to have the following fundamental skills:
-
Absolute command over programming languages
-
Superior coding skills
-
Design thinking
-
Logical reasoning
-
Ready for collaboration
-
Soft skills
Following are the specific advanced skills that an Express.js developer is expected to have:
-
The ability to find the existing Node for a specific function is a valuable skill. The developer should know how to integrate a code in the existing system.
-
A developer who knows about data flow is reliable to test a product or give its demo. They need to know about buffers, streams, and security needs.
-
A developer with prior experience in using Express.js is preferable. It is a sign that they know how to build products from the start.
-
Knowledge of debugging, i.e., identifying and removing bugs, is highly sought-after
