Who is a Backend Web Developer ?
backend developer roadmap: Unlike the frontend developer, who takes care of the visible part of a site or app, the backend developer is a computer scientist who instead builds everything that is not seen but serves to make that site or application work. If we were to use the metaphor, the backend developer is the technician who builds the foundation and structure of a house, while the frontend is the architect who cares about the facades and how to manage the spaces and movements within the house. Building.
In any case, the backend developer programs and writes code just like a normal computer developer, but his role is not “limited” only to sites and applications. Here on the ………… you can find amazing courses of Backend Web Developing.
Tasks that Backend developer do:
Since he works on the structure of digital systems, he is the profile that deals with the creation of even complex software and programs. This is why he has skills ranging from mathematics to the construction of databases and systems to manage the flow of information in areas that can be very different: from email marketing to cyber security through social networks to the maintenance of IT systems of third-party companies.
Programming Language to learn Backend
However, one of the activities that must be able to manage is that of creating and organizing digital databases conceived with systems such as Oracle or MySQL, or NoSQL, or MongoDB. This is because most companies already base their database on these models and when they hire a back-end they expect that as a professional they know how to enter and manage the related DBS.
Skills A Backend Web Developer Need in 2021
With the above-mentioned 2021 roadmap, it’s clear that backend development is a logical and technological aspect of the web app. As a result, we’ll go over the technologies and tools that are required to become a skilled backend developer.
1. Basic Internet, Operating System and Frontend Knowledge
Backend development, like frontend development, requires knowledge with the fundamentals of the internet (such as how it works, what HTTP/HTTPS is, how to work with browsers, how DNS works, and what a domain name and hosting are).
After you’ve learned the internet, you’ll need to learn about operating systems in general, including memory management, terminal usage, OS operation, process management, threads and concurrency, basic terminal commands, I/O management, and networking fundamentals.
2. Programming language
3. Version Control System
A version control system (VCS) is a technology that helps frontend and backend developers collaborate and manage changes over time. It also tells you what kind of changes are made and who is responsible for them. In brief, a version control system increases the project’s speed by allowing engineers to collaborate, limiting the risk of errors, and even recovering the code in the event of an accident.
For backend development, you can use the following version control systems.
A database is a brain that helps to make a web application dynamic in the context of a web application. The database is responsible for storing data, accepting queries, obtaining information, and returning the needed result to the web app whenever you search for a product or request logins.
Backend developers either use relational or NoSQL databases. Some of them are as follows:
You’ll need to know about a handful of the databases described above, as well as some basic database principles like ORMs, ACID, the N+1 problem, Transactions, Data Normalization, and Indexes.
APIs (Application Programming Interfaces) are a type of intermediate that allows services to communicate with one another. APIs are used by backend developers to connect different apps or services in order to give a better user experience on the frontend. You should be aware of the following APIs:
Caching is a technique for storing a copy of a resource in a cache (temporary storage location) and retrieving it fast when needed. The main goal of caching is to improve data retrieval performance while reducing the need to contact the slow-to-process underlying storage layer.
Here is a list of caching techniques and tools you should be aware of.
The process of checking the database or server-side of a web app is known as backend testing. The goal of backend testing is to determine the database layer’s efficiency while guaranteeing that it is free of data corruption, deadlocks, and data loss. Backend developers utilize the following testing methods:
8. Code Analysis Tools
Code analysis is a technique for debugging and analyzing programs to ensure that they run smoothly. To understand more about different methods and tools for analysis, check out our previous blogs: Code Analysis Tools: Code’s Journey From Developers to Testers and Static Code Analysis Tools For Java To Provide Quality Measurements.
Some of the tools used for code analysis are:
9. Architectural Patterns
An architectural pattern is a reusable solution to repeated issues in software development. The following are a some of the most regularly used architectural patterns:
- Event Sourcing
10. Message Broker
A message broker is a part of software that allows systems, apps, and services to communicate with one another. A message broker is a module that converts the server’s formal messaging protocol into the client’s formal messaging protocol (receiver). You can learn to use one of the provided message brokers in a future project.
Containerization is the packaging of software code with all required components, such as frameworks, libraries, and other dependencies, in order to create services that are isolated from one another in a container. Backend developers use containerization to make it easier to move or execute containers depending of their infrastructure or environment. Docker is one of the most commonly used containers that you should learn.
12. Design Patterns
Design Patterns are developed answers to a common set of issues that can arise during the development of a web application. It defines a common solution to such repeated problems. The following is a list of different design patterns that you should be familiar of.
- Template Method
13. Authentication Method
Authentication methods are used to verify a user’s or device’s identity in order to gain access to resources, data, or applications. The authentication phase provides the security system with a user identity. Backend developers employ a variety of techniques, including:
A webhook, often known as a reverse API, is a method for an app to give real-time data to other apps. Webhooks, unlike APIs, do not require a request to be sent after a response. Instead, webhooks provide data as soon as it becomes available, without the need for a request or specific callbacks. The webhook’s fundamental characteristic makes it useful for both users and providers.
The WebSocket API is a reducing technology that allows a two-way interactive communication session to be established between a user’s browser and a server. You can use this API to send messages to a server and obtain event-driven responses instead of asking the service. A WebSocket is a persistent link between a client and a server. It uses a TCP/IP socket connection to create a full-duplex, bi-directional communication channel over HTTP. Simply put, it’s a thin, lightweight layer over TCP that allows subprotocols to be used to lodge messages.
Why to choose Backend Job
