Tip No. 1: Initiate Projects With npm init
Use npm to initiate a new Node.js project.
Wondering what is NPM?
Well, it is an ideal method to add couplings or dependencies, and you can use it to browse every Node.js package. Using the popular packages offers numerous benefits, such as reusability, community support, and managing dependencies. Basically, it allows developers to understand the overall project environment. You can include a ton of metadata and a semantic versioning-compliant update of Node.js. And setup.npmrc to ensure that npm install always updates the package .json.
Tip No. 2: Use Environmental Variables
Configuration management deals with the procedure of decoupling the service, code, database, etc., during every phase. It includes development, production, and others. Check the NODE_ENV environment variables and use them in Node.js to develop the values from process.env in your code. Finding the values in process development becomes a breeze by utilizing environmental variables. Adding to this, to maintain code reusability across the project, choose the existing Node.js coding rule.
Tip No. 3: Avoid Synchronous Functions
For successful Node JS app development, it is crucial to avoid Synchronous Functions. Instead, make asynchronous functions a part of the code; turn on the trace, sync, and IO flags that will show a warning while encountering asynchronous APIs. Plus, it is important to simplify the logic flow and test the process. Avoiding synchronous functions can enhance the overall performance of the Node JS application. So, make sure to use this tip when developing the app.
Tip No. 4: Handle Inaccuracies
Deploying high-standard software must be the ultimate goal of every developer, so ensure that you eliminate even a minor inaccuracy. Know that it can have a negative impact on the entire process. However, you can easily handle inaccuracies by providing a catch() handler to eliminate errors effectively.
Tip No. 5: Restart the App Automatically
It is important to establish a condition for restarting the application in order to prevent any potential dependency errors that could cause the application to crash. The process manager can assist you in ensuring that the application recovers from runtime errors or when the server experiences time constraints. Alternatively, the app needs to be restarted in the event of a complete service failure. Make sure to confirm whether the app restarts when encountering specific issues.
Tip No. 6: Follow the Best JavaScript Practices
Developers need to be familiar with the Node.js best practices in JavaScript. As an app developer, you must practice writing asynchronous programming, data types, scope, function arguments, callbacks, and functions and objects in JavaScript.
Beginners can consider enrolling in a JavaScript course. It will help you learn JavaScript in detail while enhancing your knowledge about several other aspects of the programming language. Other than this, you can utilize the Azure functions or application service that offers you serverless code infrastructure. It allows for the creation of responsive HTTP endpoints.
Tip No. 7: Cluster The App
Clustering enables request parallel processing across multiple cores, which enhances the performance and responsiveness of the Node.js application. If you need to run a single process on limited hardware, cluster support can offer you increased flexibility. By clustering the app and keeping track of node execution time limits, you can significantly reduce resource usage.
Tip No. 8: Use GZIP Compression
Using GZIP compression can help you in successful NodeJS app development. GZIP is a compression technology that is used for transferring data quickly through the internet. This software is used for compressing files, and developers can adjust the settings according to the app’s requirements. Well, it is one of the highly preferred tricks that you can use for Node.js app development. GZIP compression compresses the response before sending it to a web browser, which reduces the time lag and latency.
Tip No. 9: Concatenate Numerous JS Files
Optimizing code space is an effective way to enhance the performance of applications. In that instance, concatenating multiple JS files would end up improving the app’s performance. For example, a web browser makes six different HTTP requests for every JavaScript file that cause a blockage and increases the wait time. However, concatenating them will enhance the application’s performance and offer a better user experience.
Tip No. 10: Client-Side Rendering
This is one of the best tips you can follow during NodeJS app development. Client-side JS frameworks such as Backbone JS and Angular JS provide APIs that allow JSON responses to be sent directly to clients, bypassing the need for servers. Client-side rendering reduces latency and saves bandwidth. Plus, it provides a better user experience and richer site interactions through faster loading and quick responses. So, make sure to follow this trick.
In addition, don’t track anything that’s developed using a source control system like git. This could result in redundant bloat and chaos in your git history as you follow the files created for changes.
Tip No. 11: Application Monitoring
Application monitoring is essential for understanding application downtime. Application downtime is a specific timeframe during which the system is not functioning or accessible. It is crucial to receive notifications when your production or service application experiences downtime. Otherwise, how will you identify it? Developers can monitor multiple endpoints, perform functional checks, eliminate flaky checks, configure alert notifications, and keep an eye on testing and staging environments. By following these tips, you can effectively stay alert and identify any unusual behaviours in Node JS applications.
Tip No.12: Code Testing
Code quality testing is one of the most important steps when developing an app. Whether it is Node JS or any other application, code testing should be carried out throughout the process of app development. Therefore, prioritize code quality testing besides stages of the project, which means whatever your app’s stage could be, start testing.
Another significant trick is using lowercase. Yes, in Node.js, you must use a lowercase filename for everything. For instance, some languages encourage filenames to match class names, like MyClass, but you can write my-class.js in the Node.js language.
Tip No. 13: Avoid Garbage
Node V8 uses an acquisitive and idle garbage collector that has a limit of 1.5GB. More often than not, it waits until it retrieves the lost memory. Given the circumstances, if your memory usage is increasing, it is likely due to the node’s normal idle behaviour rather than a leak. In such a scenario, it’s advised to set up the flags for V8 in your profile to control your app’s trash collector. Trust that following this tip will help you tremendously during Node.js app development.
Tip No. 14: Optimize Performance
Optimizing performance is one of the crucial practices when developing intuitive applications. Using the right tools can help you tremendously. You can use tools to check the status effectively and analyze database queries, CPU-intensive operations, and network requests. Plus, monitoring performance metrics lets the developers identify bottlenecks, inefficient code, and resource-intensive operations in applications.
