In addition to being one of the most well-liked frameworks among employers, Node.js has the biggest skills gap between the number of developers with the necessary abilities and the number of developers that companies need.
The eight abilities that any Node.js developer should prioritize are broken down in this post. Make sure your abilities are up to date by using this list, or use it to learn what it takes to become a highly sought-after Node.js web developer.
Recognize and understand Node.js. Knowing how to use the web application framework of your choice is not enough; you also need to be well-versed in the Node.js API and comprehend the fundamentals of Node.js. To help you learn more, the Node.js community has developed a new website that includes tutorials and details on advanced Node.js subjects.
Particular Node.js API domains that are frequently used in the construction of web applications are file manipulation, HTTP, and buffers. Furthermore, as the Node.js API keeps expanding, you should keep up with new capabilities like async/await.
2. Web application frameworks
The web application framework is one of the most important requirements of any Node.js online application. Using the HTTP module, you can write your own, although it’s highly encouraged to build upon the work of others who came before you. If you aren’t sure which is your favorite, there are plenty to select from. Express has a higher developer share than all other frameworks combined, according to a survey conducted by Eran Hammer. Hammer’s own framework,Hapi.js, came in second, while numerous other frameworks followed with varying degrees of market share.
In this instance, Express is not only the most widely used, but it also offers you the best opportunity of catching up with most new codebases rapidly. It also functions incredibly well and is kept up nicely.
Web security has always been important, but in light of the current breaches and problems, it is now very essential. Learn about the OWASP Top 10, which is a list of the most significant online security threats that is updated periodically. You can use this list to find and audit potential security gaps in your application.
Learn how to add secure authentication to your online application. A common middleware used for user authentication with several schemes is called Passport.
Discover how to use encryption in Node.js more effectively. A popular npm package for encryption and hashing algorithm is called Bcrypt.
It is always possible for one of your dependencies to be vulnerable, even if your code is secure. Using the ‘npm audit’ command, you may find out when to upgrade dependencies that have identified and fixed security issues.
4. How to front end
Your web application won’t be able to run with just your Node.js codebase. Understanding how to store dynamic data in a persistence layer, such as a database, is also necessary. There are far too many database alternatives to mention here, but Object-Relational Mapping (ORM) tools are frequently the best method to work with databases in Node.js.
Sequelize is a well-liked choice that provides you with a consistent API to work with irrespective of the kind of SQL database you are connected to. This allows you to simply change your database engine if necessary, in addition to providing a straightforward way to design your table schema and update records.
If you would rather use a NoSQL solution, Mongoose is among the most well-liked ORMs for MongoDB. In the end, you should be quite familiar with one of these database options.
6. Package management
One of the most dynamic aspects of the Node.js community is package management. The tool that comes with the Node.js binary is called the npm CLI, although it has numerous serious problems for years. Yarn was introduced as a substitute that addressed many of the problems that npm was unable to resolve and came with several well-known sponsors. However, competition encourages innovation, and npm is leading the pack in package management beyond Yarn’s functionality in addition to resolving those problems. Although it’s nearly impossible to choose one these days, knowing how to use a Node.js package management system is a necessary skill.
7. Cloud platforms
As your web application won’t be served from your desktop, it’s advisable to familiarize yourself with a cloud platform that you can use for its deployment. Big brands like AWS and Azure are always wise choices, but occasionally they could require more infrastructure configuration than you’d like to handle. Numerous smaller cloud providers customize their offerings to ensure a pleasant developer experience. These days, there are a plethora of choices available for quickly deploying your Node.js apps to a cloud platform, like Heroku and Netlify.
8. Source control
When developing Node.js applications, do you employ source control? Should the response not be “No duh,” then you must “get” into the program! Every application, no matter how tiny, should use source control, although there are undoubtedly varying degrees of git proficiency. Not only will you impress your friends and coworkers by learning more git commands than just “commit” and “check out,” but it will also help you maintain a tidy and organized codebase. Now that private repositories are free on GitHub, there’s no excuse not to start using source control and mastering git.
