Node.js is among the top well-known technology frameworks today as per the latest Stack Overflow Developer Survey, and its popularity keeps increasing. It's not surprising. 

The ease and flexibility of JavaScript combined with the power of an async loop with speed and a vibrant community has only increased the performance and capabilities of Node.js developers.

Node.js isn't just one of the most popular frameworks for employers but it also has the biggest gap between the amount of Node.js developers employers want as well as the number of developers who have the required abilities.

This article outlines the eight skills that each Node.js developer must focus on. Utilize this list to make sure that you're staying current with your knowledge and to determine how you can step into the next level and be a sought-after Node.js web Developer.

Top Fundamental Skills That Are Required for Node Web Developers

1. Node.js

Learn about Node.js and be familiar with it. It's not enough just to be able to use the web-based application framework you've picked and you must know the way that Node.js functions and become acquainted using its Node.js API. 

It is the Node.js community has launched an online guide and details on the most important Node.js subjects to aid you in understanding more.

Particular Node.js API-specific domains which pop up frequently in web application development include buffers, HTTP and file manipulation. 

Furthermore, it is important to note that the Node.js API continues to grow therefore you need to be aware of the latest features that are available in Node.js like wait/async.

2. Frameworks for web-based applications

One of the essential components of a Node.js web-based application is the web framework for applications. While you can write your own using HTTP, using the HTTP module, relying upon the work of those who came before you and utilizing those who have done the job is advised. 

There are a lot of options to pick from, even if you've not yet decided on a preferred one. A survey conducted by Eran Hammer shows Express as having the highest developer share of all other frameworks. 

Hapi.js came second, being developed by Hammer himself. Then, several other frameworks followed, with a small share in market shares.

In this particular case, Express is not only the most well-known and well-known, but it also offers the best chances of being able to quickly catch up with the latest codebases. Additionally, it's maintained and runs well.

3. Security

Security on the internet has always been a major problem, but due to the number of breaches and problems lately, it's a need right now. Be familiar with the OWASP Top 10 which is a frequently up-to-date list that lists the top security issues online. 

This list will allow you to determine and analyze the areas in which your application is not meeting security standards.

Learn how to offer secure authentication for your website application. Passport is a well-known middleware that lets users authenticate using different methods.

Learn how to effectively utilize encryption in Node.js. Bcrypt is an algorithm for hashing and is the most commonly used Node.js package to secure data.

Although your code may be safe, there's the chance that one of your dependencies might be vulnerable. The "npm audit" command will assist you in determining when to upgrade dependencies after having identified and addressed security concerns.

4. How to frontend

While a significant portion of your job as a Node.js Web Developer lies in the back end of Node.js code. however, you will be required to work on the front end occasionally to create your user experience. 

Becoming familiar with front-end technologies such as Client-Side JavaScript HTML and CSS is likely to allow you to make a few changes. Learn about a front-end framework to assist you in creating a great user interface without a lot of effort. 

As with everything it's many options to pick from However, React and Vue are the most popular and powerful at the moment.

5. Databases

Your Node.js codebase will not be sufficient to run your website application. It is also necessary to understand how to store your dynamic data in a layer of persistence such as the database. 

There are too many databases to mention here, but the most efficient way to work with them using Node.js is with ORM (ORM) software.

One popular option is Sequelize which provides you with an identical API to interact with no matter what kind of SQL database you connect to. 

This is not just an easy way to create tables schemas and updates but also provides you with the possibility of switching the database engine you are using if required.

Mongoose is among the most well-known ORMs available for MongoDB for those who prefer a NoSQL alternative. You must be familiar with one of these database solutions thoroughly.

6. Management of packages

Node.js management of packages is among the most dynamic aspects of the Node.js community. The CLI for npm is the program that comes with the Node.js software, but throughout the years it faced many prominent problems. 

Yarn was created as a replacement that came with several big-name sponsors and addressed several of the issues the npm CLI could not solve. However, competition is the catalyst for innovation. 

NPM has not just fixed the issues but also is creating new ideas in managing packages beyond the capabilities of Yarn. 

Nowadays, it's impossible to decide which you should choose, but having experience using the package management system using Node.js is crucial knowledge.

7. Cloud platforms

It's not possible to run your web-based application from an individual computer therefore it's best to become familiar with using a cloud platform that allows you to deploy your application. 

The most well-known names are excellent choices, like AWS or Azure However, there are times when it may require more configuration of infrastructure than you'd like to deal with. 

Some smaller cloud providers tailor their services to provide a pleasant developer experience. Today, Heroku and Netlify are just two of the options available to help you deploy your Node.js applications on cloud platforms easily.

8. Control of the source

Have you implemented source control in your Node.js applications? If your answer isn't "No duh" then you should "git" with the program! Source control is an easy task for all applications even the smallest ones. 

However, there are a variety of levels of git proficiency. Making time to become proficient with the git commands that go above "commit" and "checkout" will not only impress your colleagues and colleagues but can also help keep your codebase tidy and organized. 

With GitHub recently releasing private repositories available for free there's no reason not to get started using source control and eventually becoming a pro using the git.
