All web developers worth their salt must have proficiency in Node.js these days. It is a popularly used JavaScript runtime environment that helps build scalable network applications. One of the key reasons why it is so popular is that it facilitates the flow of two-way communication between server and client. As a developer, Node.js helps you build cutting-edge JavaScript web applications in the browser and that’s not it – you can also actually compile and execute JavaScript very quickly and in an error-free manner.
If you achieve a level of proficiency in Node.js development, there is no doubt you will be able to build web applications in the browser that your clients will fall in love with. Here are 3 best practices that will help you make good use of Node.js:
1. Structure your solution and layer components
Say you are building an enterprise-grade application; this means your application functionality is relying on a large code base. As a developer, you don’t want such dependencies to bog you down while you integrate new features into your app. This is why code needs to be partitioned into individual components with each component getting its own folder and dedicated code base. What you are actually doing here is that you are keeping the size of code to manageable levels. This can also help add a level of scalability to your app
2. Use a style guide
If you are working on Node.js, and want to make the best use of your time, it is imperative that you use a style guide. You don’t want to get stuck in a continuous reformatting cycle because you haven’t understood the code of a new file from a new client project. This is why it is so critical to write the code with consistent styling. When you follow a set of style guidelines and stick to it for all your projects, you won’t be wasting your time changing the spaces to the table or reformatting braces to makes sure they are on other lines. If you enforce a particular style guide upon yourself while coding, you will find that your job becomes easier as you can manage code better.
3. Thorough testing is a must
Irrespective of the trust in your abilities as a developer, take the project through a thorough testing process. API testing that helps your test components is the easiest and quickest to do, and you must begin with that. If you have more time on your hands, move on to performance testing, DB testing, unit testing and any other tests you want to run. When we say API test, this is the very least you can do, if you are short on time. We are not saying this is the only test you must run. Something else you can do is use code linter that will help you analyze code quality and perform the pre-code review. You can find errors before execution, which will help you correct problems before they become a major issue, which takes a lot of time to resolve.
But, it’s always important to remember that you need to assign a sufficient amount of time to test your Node.js project. Take all the time you want for coding and building the app, but you must know if you’ve got it right. This can only happen if you test.
