NodeJS’s ability to make everything possible didn’t remain in the dark to programmers; hence, the technology acquired incredible prominence in a brief period since its launch. Therefore, various coders started using NodeJS, and many companies began actively hiring Nodejs developers for their projects.
3 NodeJS development tricks to rule the 2021 market:
- Add some types and schemas:
The typless coding method has earlier proven to be error-prone and counterproductive. However, this does not imply that a developer would have to stick to strictly-typed syntax. Instead, it would be better to choose the degree of semantic code by either validating your models/entities using JSON schemas to elucidate your basic JS with static typing.
Or you can also decide to use fully-typed syntax with Typescript. The latter has managed to gain appreciation in the past few years. Thus, if you are planning on using Typescript, ask yourself whether you should expand to using typing features. Otherwise, using abstract classes and interfaces may take you to the paradigms you never wanted to try.
- Plan utilization of Async-Hooks for better tracing and context:
Many companies prefer to hire full-stack web developers to tackle the one drawback that’s associated with the single-threaded model, i.e., requests lose context. This happens when they perform asynchronous operations and flow through various files. Thus the variables remain unpreserved during their life cycle.
Why is this troublesome?
For example, developers often need to include a unique identifier within each log entry so that later every log entry can be correlated in the same request. This was not easy a few years back, but since 2019 async hooks have made it possible. Simply put, they allow injecting custom code anytime an async operation is beginning or ending.
Async hooks make it possible to preserve the context and correlate all codes in the same request.
Therefore, a developer must possess excellent skills in using the async hook appropriately and at the right time since they can lay as a foundation for several custom packages that take Node’s context and tack to another level.
- Align your monitoring with best SRE/DevOps practices:
Even a small-size application will have dozens of physically moving parts, thus staying on top of the competitive market must be carefully planned and even carefully executed. Yet, many developers fail to acquire the skill set of monitoring and alerting; site reliability engineers can give these lessons.
As an example, developers often focus or prioritize internal hardware metrics such as Memory and CPU instead of beginning with metrics that undeniably and directly affect the end-user at the current moment, such as latency or error rate.
These metrics are also referred to as “the golden signal” and in 2021, it would be great to start and embrace such great NodeJS development practices.
