Built on Chrome’s V8 JavaScript engine, Node.js is a JavaScript runtime environment. Node.js is majorly used for building scalable and lightweight network-driven apps as it is an asynchronous event-driven JavaScript-based runtime. Mentioned below are some best practices that one should follow while using Node.js:

1. Divide your Solution by Components

One of the toughest things for larger applications is to take care of an enormous code base with plenty of dependencies. This slows down development and production while adding new features. Being consistent with Node.js best practices, we should always divide the whole codebase into smaller components in order that each module gets its own folder, and certain that every module is kept small and simple.

2. Layering Components

Layering is vital and thus each component is meant to possess ‘layers’. Following node.js best practices, these layers have a particular object which will be practiced on the logic, web and data access code. Through this, it can make a tidy division of performance issues and may significantly differentiate processes from test and mock codes.

3. Begin new project with npm init

Npm init will automatically create a package.json file for your project that displays all the packages/node app of npm install that has the understanding of your project.

4. Wrap Common Utilities as npm Package

Larger project/app processes normally have similar code used frequently multiple times at distinctive locations. By combining them into one private package file and using that package at various places within our app can prove to be beneficial. Code duplication is eliminated by Npm install and it makes code more manageable.

5. Separate Express ‘app’ and ‘server’

The most common mistake that several developers commit in any project is to define the entire express application process on huge files. Rather than doing that, one should always divide the ‘Express’ definition into at least two different files.

6. Using Environment Aware, Secured and Hierarchical Configuration File

As a security best practice for Node.js, one should always keep the app-level keys simply readable from the environment and file variables. Also, one should always keep secrets outside the dedicated code and make a config file hierarchy for simple accessibility. An ideal and flawless configuration setup is required to satisfy all this. There are a few node.js development project structures that are available which will help to do this like for example nconf, config and rc.

7. Avoiding Garbage in-app

Node.js features a default limit of 1.5 GB Single CPU core as process manager but however, it uses a lethargic and greedy garbage defaulter. Node.js pauses until the memory usage is reached and gets recovered on its own.

Developed by Google, Flutter is an open-source and UI application software development kit (SDK) used to develop mobile applications for iOS, Android, Windows, Mac, Linux, etc. Flutter empowers the developers to code smooth and easy cross-platform mobile applications. Various ways that indicate Flutter is setting the trend in mobile app development are:

1. Active code writing and app testing
The Flutter application development process is very efficient. Flutter is a single codebase framework and therefore it eases and accelerates the process, making it easier and more effective. Flutter's single codebase approach helps in cutting down the development time allowing developers to reuse it with diverse plugins. Furthermore, when it comes to testing, a mere quality assurance method is adequate to check the features, program, and functionality of a cross-platform mobile app.

2. Single codebase
The write-once approach feature of the Flutter makes it stand out amongst its likes. It outdoes the traditional barriers of cross-platform approaches where developers had to write various codes for various platforms.
Flutter is considered by most of the developers as Flutter mobile app developers now only have to code once and not individually for both Android and IOS operating systems. Being a hybrid application development framework, Flutter lessens the daily efforts of both – developers and users. Therefore they can promptly update the design, speed, and quality of the application.

3. Best befitted for MVP
Using Flutter for application development can aid you in displaying your MVP to the investors. With Flutter, there is no obligation of developing two applications for iOS and Android. Flutter lets you discuss your business model with higher simplicity and aids you in acquiring funding. By skipping the process of testing and developing project prototypes can help you save both resources and time. Flutter honors MVP development. Application development becomes uncomplicated with Flutter as it increases the pace of the development process. Flutter is also compatible with Firebase and hence doesn’t require you to part backends for building easy MVP. Therefore, the Flutter mobile application for businesses will turn out to be a grand success.

4. Utilization of widgets
These days widgets are a very crucial part of the application interface. Applications integrated with Flutter provide a broad range of widgets including fonts, navigation, scrolling, etc that are customizable despite the screen size. Undoubtedly, compared to another cross-platform framework, Flutter mobile apps provide a very fluid UI experience.

5. Hot reloading
Due to its features like “Hot Reloading” or “Hot Restart”, Flutter cross-platform application development is trending amongst the developers. These traits of Flutter allow developers to inspect changes in the code within a second.
Or simply one can say that Flutter allows developers to see the progress side by side while coding. Thus, this increases the productivity of the developers, and also, it is extraordinary for fixing bugs.

6. Simple set up and maintenance
Flutter is comparatively easy to develop and maintain as it is a single codebase framework. As compared to any other app development platform, Flutter enhances the performance of the application and reduces maintenance efforts. Due to the simple and single code used in programming, maintenance of flutter is easy. Modifications are made quickly without the hustle of going back and forth on the codes again and again, once the bug is detected by the team members. Therefore, Flutter comes easy on the pocket as developers do not have to spend additional money on mighty machines.

7. Simple development language
Flutter uses Dart programming language which is based on the in-house language of Google. Dart programming language is a general-purpose and one-source language, and hence developers with even a little knowledge find the language relatively easy and smooth to access than other languages. Dart is not only used for mobile application development framework, but it is also broadly available for developing server, desktops apps, and web.

The single codebase Flutter is not going to stop anytime soon now. Everyone is aware of how swiftly it is advancing towards businesses’ success, keeping in mind the future plots. Flutter has taken over several application development frameworks efficiently and has established itself as an ideal choice for developers and users.

1. Flutter

Developed in 2013, React presents its own concepts to stand-away from other frontend web frameworks. It incited the development of a plenty of supplementary tools to reach immense flexibility and scalability. The React javascript framework leads the search volume at 57.5%.
Features of React.js:
> It helps in creating dynamic and interactive UI for both websites and mobile applications.
> React.js uses the declarative approach which makes the code easy to debug and readable.
> React.js uses the theory of “Virtual-DOM object”. A representation of real DOM elements produced by React components before any changes are made to the page is Virtual-DOM.
> It uses JSX, which is a specialised markup language that mixes HTML into JS.
> React uses “FLUX” for unidirectional flow of data or say one-way data binding.
> React.js is component-based, which means everything is a component of the web page divided into little components to create a view. Components are used to describe the interactions and visuals in applications.

2. Angular
In 2016, Google developed one of the most powerful and effective open-source JavaScript frameworks called Angular. It uses the MVC (Model-View-Controller) design pattern where Angular changes from MVC to Component-based architecture in version Angular 2.X. The framework uses the language CoffeeScript and TypeScript, which are supersets of JS.
Features of Angular:

> Angular framework is a cross-platform web framework for growing Web Apps, that is, they are reliable, capable, and installable. These pillars modify them to feel like a platform-specific application.
> Using the same Angular method to access native OS APIs, desktop installable applications can be created across Windows, Mac, and Linux.
> Angular framework is the Universal platform that serves both for the frontend and backend by using some code and library which is referred to as Angular Universal.
> Angular framework has the component referred to as Router, using Router angular apps load swiftly.
> Angular framework creates UI views with the help of simple template syntax.
> A special Chrome extension, Angular Augury, is used in order to debug applications.

Commonly known as Vue, Vue.js is an open-source JavaScript framework which is used to develop enriching user interfaces. As Vue is a progressive framework, it can be easily integrated with the existing projects and with other JS libraries. Being a reliable platform for developing cross-platform applications, one of the most winning features of Vue.js is its dual integration mode for creating high-end single-page applications.
Features of Vue.js:

> Like in React.js, Vue.js uses the concept of Virtual-DOM. The framework is the clone of the primary DOM elements which absorbs the changes made in the DOM present in the form of JavaScript and correlates with the primary data.
> Vue.js is extremely simpler and less limiting than Angular and also worth thinking instead of React.
> The framework uses the Vuex library, which is a Flux-like state management tool.
> A feature to mix HTML layouts with JS is known as Data-binding. One has to use v-if or v-bind to interpolate values to templates from the component logic.
> A JS library known as Weex supports Vue syntax and is used for mobile development.

4. Ember.js
An open-source javascript framework, Ember.js is used for the creation of a wide range of web applications. Ember javascript is an amazingly flexible and adaptable framework.

> It is used for developing javascript apps that can be maintained and reused.
> The framework utilizes CSS and HTML as the core of its development model.
> For debugging of the Ember applications, Ember Inspector tool can be used.
> Ember uses templates that help to automatically refresh everything once the content is modified.

5. Meteor.js
Meteor.js is one of the most widely used backend javascript frameworks. The basic concept of Meteor is developing a backend in less time. This is the reason why frontend developers can run backend properly with Meteor without flipping between programming languages like Python, PHP etc. It lets you use one language everywhere.

Features of Meteor.js:
> Meteor.js uses the same code for desktop, web and mobile apps.
> The framework has open-source IDevE and enables you to let you design real-time web applications.
> Meteor.js provides full-stack features for developing web apps.
> It offers necessary packages for famous frameworks like Bootstrap, Backbone.js, etc.
> The framework has built-in live-browser reloading.

All the JavaScript libraries and frameworks that have been explained above contain the great potential to grow exceptionally in the future. Every framework has its own advantages and disadvantages, and the programmer has to figure out which one has the features he/she needs for their project.
