Why ajax is important

It is also used for a variety of other tasks like Android development, but it shines in the backend because of its multithreading abilities.

So, enterprise grade web-apps and web-apps with a lot of traffic prefer Java, because it handles loads better. The most popular frameworks for backend development in Java are Spring Framework and Hibernate. Some good beginner's tutorials are - 1.

Spring framework2. JavatpointJavaScript It is a very popular choice for backend development, because on the frontend side JavaScript is the only choice. So, a lot of frontend engineers can take this choice to become Full-stack developers.

Actually, the API part can be done by numerous frameworks of Node. The other popular framework is Fastify. The two most popular frameworks for Python are Flask and Django. Some good beginner tutorials are - 1. Its popularity increased once the. NET framework was released for backend development. As Microsoft is very popular in enterprises, the. NET framework is generally preferred in enterprises.

A good tutorial to learn. NET is - 1. Dotnet FrameworkGo Go language which is also referred to as Golang, has gained popularity in recent years. It is used a lot in Backend programming and the two popular frameworks are Gin and Beego. DatabaseFor a Backend engineer, after making APIs with framework based on language, it's time to learn about Databases. Databases are used to store most of the things which we see in a web-app, from user login credentials to user posts and everything else.

In the earlier days we only used to have one type of Database and that was Relational databases, which use tables to store data. Relational databases Relational databases allow you to create, update and delete data stored in a table format. MySQL It is one of the oldest databases and was released in It is still widely in use, but there are other popular Relational databases. A good tutorial to learn MySQL is - 1.

But it gained popularity recently, as it goes very well with modern stacks containing NodeJS and other backend technologies.

A good tutorial to learn PostgreSQL is - 1. PostgreSQLOracle is the most popular and oldest relational database. It was released in and still remains the number one preference for enterprise customers.

All the big banks and other organizations, run on Oracle databases. So, the knowledge of Oracle is a must in many companies for an Engineer. A good tutorial to learn Oracle is - 1. It has got different editions, used by different audiences. It is also heavily used by enterprise users and powers a whole lot of big systems around the world. These databases have become hugely popular in the 21st century, with the rise of large web-apps which have a lot of concurrent users.

These databases can take huge loads, even millions of data connections, required by web-apps like Facebook, Amazon and others. Beside this, it is very easy to horizontally scale a NoSQL database by adding more clusters, which is a problem in Relational Databases.

It is a free to use database, but the hosting is charged if we host on popular cloud services like MongoDB atlas. Its knowledge is a must for backend engineers, who work on the modern stack. MongoDB uses json like documents to store data. A good tutorial to learn MongoDB is - 1. MongodbIt is a proprietary database service provided by Amazon. It is quite similar to MongoDB and uses key-value pairs to store data.

It is also a part of the popular AWS services. A good tutorial to learn Cassandra is - Cassandra3. In-memory databases The in-memory database is a database, which keeps all of the data in the RAM. This means it is the fastest among all databases. The most popular and widely used in-memory database is Redis. It keeps the data persistent by updating everything in the transaction log, because when systems are shut down their RAM is wiped clean.

A good tutorial to learn Redis - RedisStorageStoring the data is an important part of any application. Although this is mainly DevOps territory, every backend developer should know the basics for the same. We need to store the database data and also the backend code.

Beside this the frontend code must also be stored somewhere. Nowadays everything is stored in the cloud, which is preferred by individuals, startups and enterprises.

The two most popular cloud-based storages are — Amazon S3 Azure Blob Storage Good beginner's tutorials for both areServices and APIsThese are theoretical concepts and are implemented by various services, but a backend engineer should know them and how to use them.

Restful APIs This is by far the most popular way to get data from a database. It was made more popular, with the rise of web-apps. We have earlier discussed different languages and frameworks, which have their own implementations for these operations.

Microservices Architecture In microservice architecture, we divide a large and complex project into small, independent services. Each of these is responsible for a specific task and communicates with other services through simple APIs.

Each service is built by a small team from the beginning, and separated by boundaries which make it easier to scale up the development effort if needed. The problem with Restful APIs is that if you want some data stored in database, you need to get the whole data sent by the endpoint. On the other hand, with GraphQL, you get a query type language which can return only the part of the data which you require.

So, we will next deep dive into the methodologies in DevOps. They are similar to but not the same thing as virtual machines VMs. One of the primary differences is that containers are isolated or abstracted away from the underlying operating system and infrastructure that they run on.

Container orchestration is the automatic process of managing the work of individual containers for applications based on microservice architecture.

The popular Containerization and Orchestration tools are — Kubernetes Docker Good beginner's tutorials for both are -Kubernetes2. It aims to shorten the systems development life cycle and provide continuous delivery with high software quality.

Both of them are cloud based and are market leaders. Both of these platforms contain a wide variety of similar services. AWS It consists of over products and services for storage, database, analytics, deployment, serverless function and many more.

The AWS certifications are also one of the most in-demand certifications and a must for frontend engineers as well as Backend engineers. With these services you can directly deploy your React or other web-apps, by just hosting them on GitHub and pushing the code. Serverless Serverless computing is an execution model where the cloud provider AWS, Azure, or Google Cloud is responsible for executing a piece of code by dynamically allocating resources and only charging for the number of resources used to run the code.

The code is typically run inside stateless containers that can be triggered by a variety of events including http requests, database events, queuing services, monitoring alerts, file uploads, scheduled events cron jobs , etc.

The code that is sent to the cloud provider for execution is usually in the form of a function. Azure functions have a browser-based interface to write code to respond to events generated by http requests etc. The service accepts programming languages like C , F , Node. Serverless Framework It is an open-source web-framework written using Node. These tools help to automate the whole process of building, testing and deployment of applications.

Jenkins was written in Java and over the years has been built to support over plugins, which extend its functionalities.

It is much easier to use than Jenkins, but has a smaller community and lower user base. SecuritySecurity is an important aspect of any application. Most applications containing user personal data, like email etc, are often targeted by hackers.

They have free material available on their website, making it possible for anyone to improve their web application security. This data is then sold to the highest bidder on the dark-net. When such public breaches are reported, then it's a reputation loss for the enterprise also. So, a lot of emphasis should be given to Authentication, Access, Backups, and Encryption while setting up a database.

The databases should also be monitored for any suspicious activities. Besides this the API routes also need to be protected, so that the hacker cannot manipulate them. Career roles Most of the companies hire Frontend developers, Backend developers and DevOps engineers separately. This is because most of the enterprise projects are huge, in which roles and responsibilities are distributed.

These companies need specialists who can get the product out as soon as possible with agile and small teams. Top companies hiringAlmost every company on the planet is hiring web-developers or outsourcing the development work.

Since the past decade, the demand for developers has risen exponentially. The sites of each of these companies are web-apps excluding Apple and Microsoft , with complex frontend and backend systems.

The frontend generally consists of React or Angular and the backend is a combination of various technologies. The DevOps part is also quite important in these web-apps as they handle millions of concurrent connections at once. Salaries The salary of a beginner Frontend developer in India starts from Rs. Below are some sources for salaries. The two countries with most developers and top tech companies are USA and India. The number of jobs is more than all the other cities combined and it also has a very good startup ecosystem.

Almost all the big technology companies mentioned earlier and top Indian service companies are located in the city. After Bengaluru, the city where the greatest number of technology jobs are based is Hyderabad, followed by Chennai and then Pune.

Entry PointsThe demand for web-developers is high and anyone with a passion for creating apps can become a web-developer. An Engineering degree is not mandatory to land a job as a web developer. The most in-demand skill today and for the next 5 years is React and its ecosystem. Many Frontend and Backend developers become full stack developers at this level, by learning additional technologies.

These people manage small teams in addition to being individual contributors. After this a professional can become a Project manager, whose main responsibility is managing the team. Another role is that of Technical Project Manager, who manages the team and also has hands-on knowledge in Technology.

The last role at this level is that of a Software Architect, who handles and designs big projects and has to look at every aspect of the technology to create the enterprise app.

Generally Full-stack developers are preferred in this role, as they need to know all technologies. The highest career milestone is CTO or Chief Technology Officer, who handles all the technology teams and makes all technology decisions in a Technology company.

Job SpecializationThere are some Full stack development specializations which I see nowadays in the industry. Full stack developers who work with React in the Frontend and Java in the Backend are in great demand.

Similarly, developers who work with Angular in the Frontend and. NET in the backend are in great demand. Beside these there are many other free resources on the internet, but they may not be organized and may not have a structured approach. This is where KnowledgeHut can make a difference and serve as a one stop shop alternative with its comprehensive Instructor-led live classes.

The courses are taught by Industry experts and are perfect for aspirants who wish to become Frontend or FullStack developers. There are many people who become backend developers first by working on languages like Java and then go on to learn React to become full stack developers.

Again, many developers learn front-end development first with frameworks like React, and then become full stack developers by learning Node. This path is easier for developers because both React and Node. JS use the same language which is JavaScript. We hope you have found this blog useful, and can now take the right path to become a full stack developer. Good luck on your learning journey! Are you interested in figuring out how websites work? Eager to learn more about the world of Full-Stack Development?

Dig in! While some prefer the artistic and creative side of web development, others are drawn to the technical one. The first group is that of front-end developers, the second is of back-end developers, and the third that of full-stack developers. Most modern web applications today require over 20 different job functions and developers who can navigate across these various functions across the stack are highly valuable.

Full-stack developers are always in vogue and much sought after both in startups as well as leading enterprises owing to their versatility, ability to step in and troubleshoot areas across the technology ecosystem that goes into building a winning product, and their contribution to speed and cost-effectiveness. What is Full-Stack Development? Full-stack development refers to the development of both the front-end and back-end of a web application or website.

A full stack is made up of the front-end that deals with the user interface, the back-end that deals with data validation, and the database that acts as storage—a repository of information from the front-end through the logic layer. Each of these components come together to facilitate user interaction, to run calculations, and to power back-end functions: a full stack. Each full stack uses different tools, frameworks, and technologies.

To become a Full-Stack developer, you need to acquire the skills to use the associated front and back-end languages, tools, and frameworks so you can create your own application from start to finish. Full-Stack Developers are Jacks of multiple trades, handling both the front-end and the back-end, including servers, databases, and even clients.

A Full-Stack Developer must be able to work with all the components of a stack to ensure they work together efficiently. Full-stack development is not only about learning various front-end and back-end technologies. It's also about understanding the two areas in sufficient detail and making communication between them easy and smooth. As technologies and industries evolve, Full-Stack developers will need to learn new technologies to stay abreast of the latest trends.

This broad range of skills across the stack is a superpower for software developers. Full-Stack Development opens multi-faceted scope for growthCompanies are no longer in pursuit of specialists in software development. The preference is towards full-stack developers who are multi-faceted and cultivate a mindset to constantly upskill themselves. There is huge scope for accelerated growth as companies resort to this broad skillset that brings in speed and cost-effectiveness for their businesses.

Full-stack developers boast of a fast-tracked, multi-dimensional career growth across companies ranging across globally valued end-to-end enterprise solutions and startups. Full-stack engineers typically begin their careers as front-end or back-end developers at the entry-level, quickly moving up ranks as they perfect their technical skills.

Practice-oriented bootcamps that provide you work-like experience can help you master every aspect of development and get you industry ready in a relatively short time and are a great alternative to this.

Full-Stack Development is one of the highest paid jobsFull-stack development is one of the highest-paid jobs across the globe due to its impact on business and marketing.

This versatile approach to development helps organizations distinguish themselves and catalyses revenue growth. Full-Stack Development enables rapid project deliveryTasks related to integration, updates, front-end, and back-end coordination, and meeting client expectations—all fall within the scope of a full-stack developer role. Not only does this help in lowering the dependencies on other teams—which often delays execution—it speeds up the development cycle and brings in cost efficiencies.

The job profile also mandates effective communication with team members to streamline development processes. A full-stack developer learns to deliver results quickly with a toolkit that constitutes the most efficient tools in the industry, enabling smart and fast work. Full-Stack development is all about building versatilityA full-stack developer is a one-stop-solution of sorts for companies.

This gives them great responsibility, dependability, and credit for successful project execution. Full stack developers, with their multi-dimensional skillset are equipped to step in anywhere across the development spectrum to provide an end-to-end solution. Tech companies appreciate and value them for their versatility across the stack, which translates to speed to market.

With greater productivity comes greater responsibilityFull-stack developers get to work with the client-side as well as the server-side of the application.

This gives the developer more control over the product and makes way for far more creative flexibility. The ability to see the big picture empowers full-stack developers to make decisions faster, giving them an edge over other developers. The broad range of skills across the stack and the creative liberty coupled with good judgment skills is what increases the overall productivity of full-stack developers, empowering them to be self-reliant and move the needle on the development better and faster.

At the end of the bootcamp, you will have a portfolio of real-world projects deployed on GitHub, working through an immersive project-based curriculum focused on practical developer skills. The program equips you with world-class mentorship and real work-like experiences, enabling you to build internship-grade projects in an actual developer environment. You will deploy project portfolios on GitHub that you can impress recruiters with during your interviews. The demand for full-stack developers will steadily increase in the market as new technologies enter.

While the opportunity comes with its bells and whistles, the developers who will get ahead are the ones who will constantly keep abreast of the latest and continually hone their full-stack development skills. Designed to get you hired, the program offers live instructor-led sessions, hands-on practice with Cloud Labs, on-demand self-paced learning, one-on-one mentorship, capstone projects, assignments, assessments, quizzes and more.

Ready to become a Full-Stack Developer? What is React Redux? One of the most popular UI libraries in use today, React is opensource and is maintained by Facebook.

React has the best community support, with millions of developers who take part in discussions on best practices, React architecture, and the way forward with React. You can read more about React here. In this blog you are going to learn about React Redux. We can use it along with React for state management within the application. Prerequisites:This blog expects you to have good knowledge of JavaScript. Please ensure that the latest versions of npm and node are installed in your machine.

Redux is a predictable state container for JavaScript apps, which means that Redux is predictable and it stores the state of your application. Redux will store and manage the application state. Redux itself is a standalone library that can be used with any UI layer or framework. You can read more about Redux here. When we are building a large-scale application, there is a need for a state management tool to avoid prop drilling all through the component. Redux is the most popular and widely used state management tool today.

Note: Redux does what context api does in React. However, Redux was introduced before context api was introduced, and it continues to be the most popular state management library. In the next part of this article, you will learn to use Redux and in later parts you can learn how to integrate it with your React application. Learn Redux:Here you will understand the essential core concepts of Redux before learning how to use it with React.

Start with creating an empty folder with the name Redux-Learnings in your desired location and open the folder in your favourite editor. VScode is preferred. Initially your project folder looks like this when it is opened in VScode:It should be empty.

Open integrated terminal for vscode and navigate to the project location. Next, run the below command in our terminal to initialize package. Command: npm init —yesThere should be a package. The next step is to install redux as a dependency for our project. Run the below command in the terminal to add redux as a dependency.

Command: npm install reduxIf you check package. Now, run the below command to run the index. On the other hand, in classical web applications, the user has to wait to receive a server response after sending a request to the server. The user cannot perform any other task during this process. You can get asynchronous communication with the server that provides you necessary nonlinear workflow.

While implementing AJAX, the developer must be extremely cautious while binding the data to the template. Any missed field or entry can lead to the UI breakage.

There are many advantages and disadvantages of AJAX technology, and the most challenging thing in this approach is it uses a lot of scripting written in JavaScript. The JavaScript code is hard to read, test, and debug. In classic web designs, the application interface is coded individually with the logic that makes the application easy to manage and develop. On the other hand, AJAX development mixes up design and breaks all mark-up and logic.

So it is hard for programmers to design and develop complicated applications. A key solution to this problem is to make use of external JavaScript files and then reference them within the DOM. Google Maps, Social Media Newsfeed, and Google suggests are two examples of new generation web applications.

However, many companies are following this technique as an Amazon search engine and photo sharing sites. Microsoft has also implemented the window live messenger and windows live mail AJAX supporting programs. Status is an established and well-known software development firm.
