If you’re a developer looking for career growth, you’ve probably already heard of the Node. It allows you to create an immense range of applications, from social media to instant messaging, collaboration tools, online gaming, and much more. Many companies such as LinkedIn, PayPal, Uber, and Walmart have already chosen to move their tech needs to Node.JS.
While learning a language or framework is a good initiative, it will be pointless if you don’t set yourself a goal for it and plan how you’ll use your knowledge to build real-world applications. Identifying a clear goal will always be your first step in becoming a better developer. Let’s now look into what Node.JS is about.
What Do We Understand By Node.JS?
Its wide range of frameworks (such as AdonisJs, Express.js. Meteor.js, and NestJs), effectively cutting development time by allowing you to incorporate the great features they propose without spending hours writing code from scratch.
We’ve compiled a list of the skills necessary to become a Node.JS talent:
- Must master front-end technologies like HTML5 and CSS3
- Must have at least a basic understanding of Node.js and other systems (Express, Meteor, etc.)
- Must be able to identify and navigate asynchronous programming
- Must possess a working knowledge of templating languages on the server-side (Jade, EJS)
- Experience with preprocessors for server-side CSS (like Stylus) will be required
- Actionable experience in user authentication and authorization between several systems/servers and different environments
- Ability to integrate several data sources into a unique and fluid system.
- Know their way around multiple delivery channels, understand their variations, and be able to maximize overall performance
- Strong tools expertise for code versioning (Git)
- Need to master the core principles of development devices for Node.js (like npm, grunt, gulp, brunch, etc)
- Show error management skills
Let’s now go into the proper step-by-step of refining your Node.js practice, and a few things to consider:
Learning the Basics of Node.JS
Its event-driven design allows you to manage several requests simultaneously. The single-threaded event loop model also means that a single thread in Node.js will conduct client requests.
Installation of Node.js
To install a stable version of Node.js, simply download it from the official website; it will configure itself based on your OS and system configs, and you’ll be able to start working on it instantly (note: do make sure that your RAM is at least 4 GB).
Node Package Manager
Node.js notably offers a node package manager, comprised of over 80,000 libraries with unique code that proposes various functions. The NPM command allows you to easily install the library you want and implement it in your project right away. These libraries are one of the most interesting features of Node.js since they accelerate the entire development process.
Another useful component of the environment is JSON files, and creating them should be your first order of business when using Node.js. It will be the manifest file with your project’s metadata, and you’ll be able to localize it in your app with the name package.json. This can be useful when you have to review data about the packages and dependencies used in the application.
Using Typescript features strategically
Focusing on Docker and Kubernetes knowledge
While DevOps still needs to convince some, developers should still consider production run-time, and make informed choices for the intersection of Dev and Ops. This procedure ensures that all outgoing requests are replayed on failures (the pattern of the circuit breaker). You could either use dedicated packages on the code for that or use K8S Istio on the infrastructure.
Nowadays, malicious activities are ever-present, and security simply shouldn’t be entirely outsourced or dependent on static security scanners. The secret is to provide training to developers to incorporate security DNA within your company. A helpful first step in improving your knowledge and practice of security would be to undergo vulnerable code and attack vector instances.
Learning ELK or Prometheus
Incorporating a monitoring mechanism is a vital step to further compliance between Dev and Ops. It’s key that developers are involved in that process, and by configuring systems like ELK and Prometheus, they can learn a great deal about exposing metrics.
Implementing gradual deployment techniques
You need to remember that your deployment engine catches mistakes and bugs even before your users do, which you can use to your advantage by distinguishing the process of deployment from the launch phase. The core idea is to propose the next iteration of your project to a pool of users and testing whether it works.
Experimenting with Async toolbox
Version 11.7 of the async toolbox introduces worker threads, which can fix the unpleasant blind spots in a node when only 1-10% of requests pick up the CPU for a long time. This can be prevented immediately by most non-Node frameworks (thread per request). Node.js, particularly, will be enough for 1 to be CPU-intensive while serving 1000 req/sec – meaning the remaining 999 suffer. While there is no full cure, you can now ensure that a dedicated event loop will spin-up worker threads so that the main one can stay snappy.
Making use of machine learning as a black-box product
Node.js is not only incredibly quick and efficient, it also has the world’s largest package ecosystems. This invaluable platform has convinced many with its multi-faceted uses, from creating the backend to build an API. 2021 is likely to have a lot in store for us as Node.JS’ popularity keeps rising.
If your ongoing project requires certain skills, you can also look into hiring Node.js developers who have already gone through this ordeal and will help you complete your projects on time, until you can do it yourself.
